My form submit button is not showing correctly

- by JackR

I have created an form that submits the contents to email. I have used the exact same coding in many other websites, but for my new website http://www.peterevansfuneraldirectors.co.uk/contact-us.html the submit button is just a grey square with text, rather than the usual button. Also the hand doesn't come up on hover. My form code is... <form action="php/FormToEmail.php" method="post" name="ContactForm" id="ContactForm" onsubmit="MM_validateForm('name','','R','email','','RisEmail','message subject','','R','message','','R');return document.MM_returnValue" > <div class="form-text"> <b>Name<span class="purple">*</span></b><br /> <input name="name" type="text" id="name" size="35" style="height:23px; background-color:#FFF; color:#000; border: 1px solid #CCC;" /> </div><br /> <div class="form-text"> <b>Email<span class="purple">*</span></b><br /> <input name="email" type="text" id="email" size="35" style="height:23px; background-color:#FFF; color:#000; border: 1px solid #CCC;" /> </div><br /> <div class="form-text"> <b>Message Subject<span class="purple">*</span></b><br /> <input name="message subject" type="text" id="message subject" size="35" style="height:23px; background-color:#FFF; color:#000; border: 1px solid #CCC;" /> </div><br /> <div class="form-text"> <b>Message<span class="purple">*</span></b><br /> <textarea name="message" type="text" id="message" rows="8" cols="55" style="background-color:#FFF; color:#000; border: 1px solid #CCC;" ></textarea> </div><br /> <div class="submit-button"> <input type="submit" name="submit" value="Submit" /> </div> </form> Thanks in advance!

Add/delete row from a table

- by yogsma

I have this table with some dependents information and there is a add and delete button for each row to add/delete additional dependents. When I click "add" button, a new row gets added to the table, but when I click the "delete" button, it deletes the header row first and then on subsequent clicking, it deletes the corresponding row. Here is what I have: Javascript code function deleteRow(row){ var d = row.parentNode.parentNode.rowIndex; document.getElementById('dsTable').deleteRow(d); } HTML code <table id = 'dsTable' > <tr> <td> Relationship Type </td> <td> Date of Birth </td> <td> Gender </td> </tr> <tr> <td> Spouse </td> <td> 1980-22-03 </td> <td> female </td> <td> <input type="button" id ="addDep" value="Add" onclick = "add()" </td> <td> <input type="button" id ="deleteDep" value="Delete" onclick = "deleteRow(this)" </td> </tr> <tr> <td> Child </td> <td> 2008-23-06 </td> <td> female </td> <td> <input type="button" id ="addDep" value="Add" onclick = "add()"</td> <td> <input type="button" id ="deleteDep" value="Delete" onclick = "deleteRow(this)" </td> </tr> </table>

menu with: hover, click, class change and ajax

- by abdullah kahraman

Hello! I have made a menu that adds class "active" on hover to each li, and removes the class when hovered out, except on li s that has a class "active" already. So far, this is done. However I have another .click() on every li that loads a content to somewhere with ajax. The problem starts here, when I click, I want to add class "active" to clicked element and remove class from all of them. I add the class, but the li that had class "active" before the click doesn't get "active" when hovered, I think the "active" class is not removed from it? Can anyone help? <div id="menu"> <ul> <li><a href="index.php" id="homeLink">home</a></li> <li><a href="#">news</a></li> <li><a id="test" href="#" class="active">blog</a></li> <li><a href="#">gallery</a></li> <li><a href="#">about</a></li> <li><a href="contact.php" id="contactLink">contact</a></li> <li id="ajaxP" style="display:none"><img alt="loading" style="border:none;" src="images/ajax-loader.gif"/></li> </ul> </div> Here is the jquery: $("#menu").find("a").not(".active").each(function(){ $(this).hover(function(){ alert($(this)); $(this).addClass("active"); },function(){ $(this).not(".clicking").removeClass("active"); }); }); $("#homeLink").click(function(){ var myThis=$(this); $("#ajaxP").fadeIn("slow"); $("#normalcontent").hide("slow").load("index.php #normalcontent").slideDown("slow"); $("#primarycontainer").hide("slow").load("index.php #primarycontainer").slideDown("slow"); $("#ajaxP").fadeOut("normal"); $("#menu").find("a").each(function(){ $(this).unbind('mouseover').unbind("mouseout"); $(this).removeClass("active clicking"); }); myThis.addClass("active clicking"); return false; });

How to fine tune FluentNHibernate's auto mapper?

- by Venemo

Okay, so yesterday I managed to get the latest trunk builds of NHibernate and FluentNHibernate to work with my latest little project. (I'm working on a bug tracking application.) I created a nice data access layer using the Repository pattern. I decided that my entities are nothing special, and also that with the current maturity of ORMs, I don't want to hand-craft the database. So, I chose to use FluentNHibernate's auto mapping feature with NHibernate's "hbm2ddl.auto" property set to "create". It really works like a charm. I put the NHibernate configuration in my app domain's config file, set it up, and started playing with it. (For the time being, I created some unit tests only.) It created all tables in the database, and everything I need for it. It even mapped my many-to-many relationships correctly. However, there are a few small glitches: All of the columns created in the DB allow null. I understand that it can't predict which properties should allow null and which shouldn't, but at least I'd like to tell it that it should allow null only for those types for which null makes sense in .NET (eg. non-nullable value types shouldn't allow null). All of the nvarchar and varbinary columns it created, have a default length of 255. I would prefer to have them on max instead of that. Is there a way to tell the auto mapper about the two simple rules above? If the answer is no, will it work correctly if I modify the tables it created? (So, if I set some columns not to allow null, and change the allowed length for some other, will it correctly work with them?) EDIT: I managed to achieve the above by using Fluent NHibernate's convention API. Thanks to everyone who helped! However, there is one more thing: after checking out the convention API, I really would like my IDs to be calld "ID", not "Id", but it seems to me that the PrimaryKey.Name.Is(x => "ID") is not working at all. If I add it to the conventions collection and rewrite my entities' properties to "ID" instead of "Id", it throws an exception that there is no primary key mapped. Any thoughts on this?

How to loop a json array and update links

- by azz0r

Hello, On page load, I do one call to get the current status of all the favourite links (display the right message aka: click to subscribe, click to unsubscribe. So far I have the following code: $(InitFavorite); function InitFavorite(){ var jList = $(".favourite_link"); var ids_to_check = {};//new Array(); $.each(jList, function () { var id = this.id; var object = id.split("_"); if (!ids_to_check[object[1]]) { ids_to_check[object[1]] = []; } ids_to_check[object[1]].push(object[0]); }); //console.log(ids_to_check); $.ajax({ type: 'POST', url: '/user/subscription/favourite-listing', data: ids_to_check, dataType: 'json', beforeSend: function(x) { if(x && x.overrideMimeType) { x.overrideMimeType("application/j-son;charset=UTF-8"); } }, error: function() { alert(1); }, success: function(returned_values) { $.each(returned_values, function() { console.log($(this)); }) } }); } My returned data is: {"env":"development","loggedIn":true,"translate":{},"aaron":"{\"Playlist\":{\"10\":\"Stop Recieving Updates For This Playlist\"},\"Clip\":{\"26\":\"Recieve Updates For This Clip\",\"27\":\"Recieve Updates For This Clip\",\"28\":\"Recieve Updates For This Clip\",\"29\":\"Stop Recieving Updates For This Clip\",\"30\":\"Recieve Updates For This Clip\"}}"} I would like it to loop through the data and for example update the class <a href="/user/subscription/toggle/id/26/object/Clip" class="favourite_link" id="26_Clip"> <img src="/design/images/icon/subscribe.png"> Add Clip To Favourites</a> However eaching through returned_values equals this in firebug: ["{", """, "P", "l", "a", "y", "l", "i", "s", "t", """, ":", "{", """, "1", "0", """, ":", """, "S", "t", "o", "p", " ", "R", "e", "c", "i", "e", "v", "i", "n", "g", " ", "U", "p", "d", "a", "t", "e", "s", " ", "F", "o", "r", " ", "T", "h", "i", "s", " ", "P", "l", "a", "y", "l", "i", "s", "t", """, "}", ",", """, "C", "l", "i", "p", """, ":", "{", """, "2", "6", """, ":", """, "R", "e", "c", "i", "e", "v", "e", " ", "U", "p", "d", "a", "t", "e", "s", " ", "F", "o", "r", " ", "T", "h", "i", "s", " ", "C", "l", "i", "p", """, ",", """, "2", "7", """, ":", """, "R", "e", "c", "i", "e", "v", "e", " ", "U", "p", "d", "a", "t", "e", "s", " ", "F", "o", "r", " ", "T", "h", "i", "s", " ", "C", "l", "i", "p", """, ",", """, "2", "8", """, ":", """, "R", "e", "c", "i", "e", "v", "e", " ", "U", "p", "d", "a", "t", "e", "s", " ", "F", "o", "r", " ", "T", "h", "i", "s", " ", "C", "l", "i", "p", """, ",", """, "2", "9", """, ":", """, "S", "t", "o", "p", " ", "R", "e", "c", "i", "e", "v", "i", "n", "g", " ", "U", "p", "d", "a", "t", "e", "s", " ", "F", "o", "r", " ", "T", "h", "i", "s", " ", "C", "l", "i", "p", """, ",", """, "3", "0", """, ":", """, "R", "e", "c", "i", "e", "v", "e", " ", "U", "p", "d", "a", "t", "e", "s", " ", "F", "o", "r", " ", "T", "h", "i", "s", " ", "C", "l", "i", "p", """, "}", "}"] How would I successfully loop that json array?

set/unset checkboxes in JSF

- by mykola

Hello, i've got one problem with checkboxes in JSF. I want them to behave dependently on each other, e.g., when i check a box which belongs to some object that has children then all checkboxes that belong to these children components must be checked either. And also when i uncheck one of child's checkbox the parent should be unchecked too. It's pretty simple with plain HTML/javascript, but i can't do anything with this under JSF. For some reason i can't set ID's for them because all checkboxes are rendered dynamically in a treetable and it prevents me from setting my own ID's, i.e. whatever i set in ID property only constant part will apply, all dynamic data that i pass is ignored. I tried to do it through valueChangeListener or validator but in both cases after i set needed values something sets them back! I don't know who does it and i can't do anything with this. Here's some code (i use OpenFaces treeTable): <o:treeTable id="instTreeTable" var="inst" ...> <...> <o:column id="isGranted" width="10%"> <f:facet name="header"> <h:outputText value="#{msg.access_granted}" /> </f:facet> <h:selectBooleanCheckbox value="#{inst.assignedToUser}" styleClass="treeTableText" valueChangeListener="#{MbUserInstitutions.onAccessGrantedChanged}" > <a4j:support event="onchange" reRender="instTreeTable"/> </h:selectBooleanCheckbox> </o:column> <...> </o:treeTable> MbUserInstitutions: public void onAccessGrantedChanged(ValueChangeEvent event) { Boolean granted = (Boolean) event.getNewValue(); Institution inst = getInstitution(); if (granted.booleanValue() && inst.hasChildren()) { setChildrenInsts(inst); } else if (!granted.booleanValue() && inst.getParentId() != null){ unsetParentInst(inst); } } private Institution getInstitution() { return (Institution) Faces.var("inst"); } private void setChildrenInsts(Institution parent) { for (Institution child: parent.getChildren()) { child.setAssignedToUser(true); if (child.hasChildren()) { setChildrenInsts(child); } } } private void unsetParentInst(Institution child) { child.setAssignedToUser(false); for (Institution inst: coreInsts) { if (inst.getId().equals(child.getParentId())) { unsetParentInst(inst); break; } } }

using CSS to center FLOATED input elements wrapped in a DIV

- by Tim

There's no shortage of questions and answers about centering but I've not been able to get it to work given my specific circumstances, which involve floating. I want to center a container DIV that contains three floated input elements (split-button, text, checkbox), so that when my page is resized wider, they go from this: ||.....[ ][v] [ ] [ ] label .....|| to this ||......................[ ][v] [ ] [ ] label.......................|| They float fine, but when the page is made wider, they stay to the left: ||.....[ ][v] [ ] [ ] label .......................................|| If I remove the float so that the input elements are stacked rather than side-by-side: [ ][v] [ ] [ ] label then they DO center correctly when the page is resized. SO it is the float being applied to the elements of the DIV#hbox inside the container that is messing up the centering. Is what I want to do impossible because of the way float is designed to work? Here is my DOCTYPE, and the markup does validate at w3c: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> Here is my markup: <div id="term1-container"> <div class="hbox"> <div> <button id="operator1" class="operator-split-button">equals</button> <button id="operator1drop">show all operators</button> </div> <div><input type="text" id="term1"></input></div> <div><input type="checkbox" id="meta2"></input><label for="meta2" class="tinylabel">meta</label></div> </div> </div> And here's the (not-working) CSS: #term1-container {text-align: center} .hbox {margin: 0 auto;} .hbox div {float:left; } I have also tried applying display: inline-block to the floated button, text-input, and checkbox; and even though I think it applies only to text, I've also tried applying white-space: nowrap to the #term1-container DIV, based on posts I've seen here on SO. And just to be a little more complete, here's the jQuery that creates the split-button: $(".operator-split-button").button().click( function() { alert( "foo" ); }).next().button( { text: false, icons: { primary: "ui-icon-triangle-1-s" } }).click( function(){positionOperatorsMenu();} ) })

how to update an Android ListActivity on changing data of the connected SimpleCursorAdapter

- by 4485670

I have the following code. What I want to achieve is to update the shown list when I click an entry so I can traverse through the list. I found the two uncommented ways to do it here on stackoverflow, but neither works. I also got the advice to create a new ListActivity on the data update, but that sounds like wasting resources? EDIT: I found the solution myself. All you need to do is call "SimpleCursorAdapter.changeCursor(new Cursor);". No notifying, no things in UI-Thread or whatever. import android.app.ListActivity; import android.database.Cursor; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.ListView; import android.widget.SimpleCursorAdapter; public class MyActivity extends ListActivity { private DepartmentDbAdapter mDbHelper; private Cursor cursor; private String[] from = new String[] { DepartmentDbAdapter.KEY_NAME }; private int[] to = new int[] { R.id.text1 }; private SimpleCursorAdapter notes; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.departments_list); mDbHelper = new DepartmentDbAdapter(this); mDbHelper.open(); // Get all of the departments from the database and create the item list cursor = mDbHelper.fetchSubItemByParentId(1); this.startManagingCursor(cursor); // Now create an array adapter and set it to display using our row notes = new SimpleCursorAdapter(this, R.layout.department_row, cursor, from, to); this.setListAdapter(notes); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); // get new data and update the list this.updateData(safeLongToInt(id)); } /** * update data for the list * * @param int departmentId id of the parent department */ private void updateData(int departmentId) { // close the old one, get a new one cursor.close(); cursor = mDbHelper.fetchSubItemByParentId(departmentId); // change the cursor of the adapter to the new one notes.changeCursor(cursor); } /** * safely convert long to in to save memory * * @param long l the long variable * * @return integer */ public static int safeLongToInt(long l) { if (l < Integer.MIN_VALUE || l > Integer.MAX_VALUE) { throw new IllegalArgumentException (l + " cannot be cast to int without changing its value."); } return (int) l; } }

JPA Inheritance and Relations - Clarification question

- by Michael

Here the scenario: I have a unidirectional 1:N Relation from Person Entity to Address Entity. And a bidirectional 1:N Relation from User Entity to Vehicle Entity. Here is the Address class: @Entity public class Address implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) privat Long int ... The Vehicles Class: @Entity public class Vehicle implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @ManyToOne private User owner; ... @PreRemove protected void preRemove() { //this.owner.removeVehicle(this); } public Vehicle(User owner) { this.owner = owner; ... The Person Class: @Entity @Inheritance(strategy = InheritanceType.JOINED) @DiscriminatorColumn(name="PERSON_TYP") public class Person implements Serializable { @Id protected String username; @OneToMany(cascade = CascadeType.ALL, orphanRemoval=true) @JoinTable(name = "USER_ADDRESS", joinColumns = @JoinColumn(name = "USERNAME"), inverseJoinColumns = @JoinColumn(name = "ADDRESS_ID")) protected List<Address> addresses; ... @PreRemove protected void prePersonRemove(){ this.addresses = null; } ... The User Class which is inherited from the Person class: @Entity @Table(name = "Users") @DiscriminatorValue("USER") public class User extends Person { @OneToMany(mappedBy = "owner", cascade = {CascadeType.PERSIST, CascadeType.REMOVE}) private List<Vehicle> vehicles; ... When I try to delete a User who has an address I have to use orphanremoval=true on the corresponding relation (see above) and the preRemove function where the address List is set to null. Otherwise (no orphanremoval and adress list not set to null) a foreign key contraint fails. When i try to delete a user who has an vehicle a concurrent Acces Exception is thrown when do not uncomment the "this.owner.removeVehicle(this);" in the preRemove Function of the vehicle. The thing i do not understand is that before i used this inheritance there was only a User class which had all relations: @Entity @Table(name = "Users") public class User implements Serializable { @Id protected String username; @OneToMany(mappedBy = "owner", cascade = {CascadeType.PERSIST, CascadeType.REMOVE}) private List<Vehicle> vehicles; @OneToMany(cascade = CascadeType.ALL) @JoinTable(name = "USER_ADDRESS", joinColumns = @JoinColumn(name = "USERNAME") inverseJoinColumns = @JoinColumn(name = "ADDRESS_ID")) ptivate List<Address> addresses; ... No orphanremoval, and the vehicle class has used the uncommented statement above in its preRemove function. And - I could delte a user who has an address and i could delte a user who has a vehicle. So why doesn't everything work without changes when i use inheritance? I use JPA 2.0, EclipseLink 2.0.2, MySQL 5.1.x and Netbeans 6.8

jquery, manipulate content inserted by ajax, without using the callback

- by Cody

I am using ajax to insert a series of informational blocks via a loop. The blocks each have a title, and long description in them that is hidden by default. They function like an accordion, only showing one description at a time amongst all of the blocks. The problem is opening the description on the first block. I would REALLY like to do it with javascript right after the loop that is creating them is done. Is it possible to manipulate elements created ofter an ajax call without using the callback?  <style> .placeholder, .long_description{ display:none;} </style> </head><body> <script> /* yes, this script is in the body, dont know if it matters */ $(document).ready(function() { $(".placeholder").each(function(){ // Use the divs to get the blocks var blockname = $(this).html(); // the contents if the div is the ID for the ajax POST $.post("/service_app/dyn_block",'form='+blockname, function(data){ var divname = '#div_' + blockname; $(divname).after(data); $(this).setupAccrdFnctly(); //not the actual code }); }); /* THIS LINE IS THE PROBLEM LINE, is it possible to reference the code ajax inserted */ /* Display the long description in the first dyn_block */ $(".dyn_block").first().find(".long_description").addClass('active').slideDown('fast'); }); </script>    <div id="div_servicetype" class="placeholder">servicetype</div> <div id="div_custtype" class="placeholder">custtype</div> <div id="div_custinfo" class="placeholder">custinfo</div> <div id="div_businfo" class="placeholder">businfo</div> </body>

meteor mongodb _id changing after insert (and UUID property as well)

- by lommaj

I have meteor method that does an insert. Im using Regulate.js for form validation. I set the game_id field to Meteor.uuid() to create a unique value that I also route to /game_show/:game_id using iron router. As you can see I'm logging the details of the game, this works fine. (image link to log below) Meteor.methods({ create_game_form : function(data){ Regulate.create_game_form.validate(data, function (error, data) { if (error) { console.log('Server side validation failed.'); } else { console.log('Server side validation passed!'); // Save data to database or whatever... //console.log(data[0].value); var new_game = { game_id: Meteor.uuid(), name : data[0].value, game_type: data[1].value, creator_user_id: Meteor.userId(), user_name: Meteor.user().profile.name, created: new Date() }; console.log("NEW GAME BEFORE INSERT: ", new_game); GamesData.insert(new_game, function(error, new_id){ console.log("GAMES NEW MONGO ID: ", new_id) var game_data = GamesData.findOne({_id: new_id}); console.log('NEW GAME AFTER INSERT: ', game_data); Session.set('CURRENT_GAME', game_data); }); } }); } }); All of the data coming out of the console.log at this point works fine After this method call the client routes to /game_show/:game_id Meteor.call('create_game_form', data, function(error){ if(error){ return alert(error.reason); } //console.log("post insert data for routing variable " ,data); var created_game = Session.get('CURRENT_GAME'); console.log("Session Game ", created_game); Router.go('game_show', {game_id: created_game.game_id}); }); On this view, I try to load the document with the game_id I just inserted Template.game_start.helpers({ game_info: function(){ console.log(this.game_id); var game_data = GamesData.find({game_id: this.game_id}); console.log("trying to load via UUID ", game_data); return game_data; } }); sorry cant upload images... :-( https://www.evernote.com/shard/s21/sh/c07e8047-de93-4d08-9dc7-dae51668bdec/a8baf89a09e55f8902549e79f136fd45 As you can see from the image of the console log below, everything matches the id logged before insert the id logged in the insert callback using findOne() the id passed in the url However the mongo ID and the UUID I inserted ARE NOT THERE, the only document in there has all the other fields matching except those two! Not sure what im doing wrong. Thanks!

jQuery mobile ajax login form authentication

- by Jakub Zak

I know i already asked simillar question, but now when I work with jQuery Mobile I can't figure it out. So I have this form: <div data-role="page" data-theme="a" id="login_page"> <div data-role="header" data-position="fixed"> <h1>****</h1> </div> <div data-role="content"> <form id="login_form" method="POST" data-ajax="false"> <label for="basic">Username:</label> <input type="text" name="name" id="username" value=""/> <label for="basic">Password:</label> <input type="password" name="password" id="password" value=""/> <input type="submit" value="Login" id="login" name="login"/> </form> </div> <div data-role="footer" data-position="fixed"> <div data-role="navbar"></div> </div> </div> And I need to submit Username and Password to php script, where php replies and send "success" or "failed". Here is php: <?php session_start(); $username = $_POST["name"]; $password = $_POST["password"]; include('mysql_connection.php'); mysql_select_db("jzperson_imesUsers", $con); $res1 = mysql_query("SELECT * FROM temp_login WHERE username='$username' AND password='$password'"); $count=mysql_num_rows($res1); if($count==1){ echo "success"; }else{ echo "failed"; } ?> And to do all this I want to use this script: $(document).ready(function() { $("form").submit(function(){ $.mobile.showPageLoadingMsg(); $.ajax({ url: "http://imes.jzpersonal.com/login_control.php", type: "POST", dataType: "jsonp", jsonp: "jsoncallback", data: $("form#login_form").serialize(), success: function( response ){ $.mobile.changePage( "http://imes.jzpersonal.com/user_panel.html"); } }); return false; }); }); But I can't make it work, I know I must have mistakes in there, I just can't find them, or better way to do it. Thank you in advance for any help.

ASP.NET Elements are null when assigning data source

- by deccks

For some reason, all of the objects in my ASP.NET markup are now null when I try to assign values to their properties in the code behind. My project was going fine and then now when I try to assign a data source to a GridView, I get a null reference error. I have no idea why it's doing this. I am not doing nothing special. I am just trying to assign a value to a property to an asp.net element in on the page. The intellisense knows that the element is there and I get no errors when I build the project. It's just when I am running the website I get the null reference. I have been trying to fix this issue for a couple weeks now. Please Help. Thanks. Here is the code: protected void Page_PreRender(object sender, EventArgs e) { LoadData(); } private void LoadData() { Entities context = new Entities(); var types = (from t in context.CustomerTypes select t).OrderBy(t => t.TypeName); gvCustomerTypes.DataSource = types; gvCustomerTypes.DataBind(); } and on in the markup the gridview looks like this: <asp:GridView ID="gvCustomerTypes" runat="server" ShowHeader="true" GridLines="Both" AutoGenerateColumns="false" AlternatingRowStyle-BackColor="AliceBlue" Width="100%"> <Columns> <asp:TemplateField HeaderText="Customer Type Name" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left"> <ItemTemplate> <asp:Label ID="lblType" runat="server" Text='<%# Eval("TypeName") %>' /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Edit" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"> <ItemTemplate> <asp:HyperLink ID="HyperLink1" NavigateUrl='<%#Eval("CustomerTypeID", "CreateEditCustomerType.aspx?ID={0}") %>' Text="Edit" runat="server" /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Delete" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"> <ItemTemplate> <asp:LinkButton ID="LinkButton1" CommandName='<%#Eval("CustomerTypeID") %>' OnClientClick="javascript:return confirm('Are you sure you want to delete this Customer Type?');" OnCommand="DeleteCustomerType" Text="Delete" runat="server" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>

What to name 2 methods with same signatures

- by coffeeaddict

Initially I had a method in our DL that would take in the object it's updating like so: internal void UpdateCash(Cash Cash) { using (OurCustomDbConnection conn = CreateConnection("UpdateCash")) { conn.CommandText = @"update Cash set captureID = @captureID, ac_code = @acCode, captureDate = @captureDate, errmsg = @errorMessage, isDebit = @isDebit, SourceInfoID = @sourceInfoID, PayPalTransactionInfoID = @payPalTransactionInfoID, CreditCardTransactionInfoID = @CreditCardTransactionInfoID where id = @cashID"; conn.AddParam("@captureID", cash.CaptureID); conn.AddParam("@acCode", cash.ActionCode); conn.AddParam("@captureDate", cash.CaptureDate); conn.AddParam("@errorMessage", cash.ErrorMessage); conn.AddParam("@isDebit", cyberCash.IsDebit); conn.AddParam("@PayPalTransactionInfoID", cash.PayPalTransactionInfoID); conn.AddParam("@CreditCardTransactionInfoID", cash.CreditCardTransactionInfoID); conn.AddParam("@sourceInfoID", cash.SourceInfoID); conn.AddParam("@cashID", cash.Id); conn.ExecuteNonQuery(); } } My boss felt that creating an object every time just to update one or two fields is overkill. But I had a couple places in code using this. He recommended using just UpdateCash and sending in the ID for CAsh and field I want to update. Well the problem is I have 2 places in code using my original method. And those 2 places are updating 2 completely different fields in the Cash table. Before I was just able to get the existing Cash record and shove it into a Cash object, then update the properties I wanted to be updated in the DB, then send back the cash object to my method above. I need some advice on what to do here. I have 2 methods and they have the same signature. I'm not quite sure what to rename these because both are updating 2 completely different fields in the Cash table: internal void UpdateCash(int cashID, int paypalCaptureID) { using (OurCustomDbConnection conn = CreateConnection("UpdateCash")) { conn.CommandText = @"update Cash set CaptureID = @paypalCaptureID where id = @cashID"; conn.AddParam("@captureID", paypalCaptureID); conn.ExecuteNonQuery(); } } internal void UpdateCash(int cashID, int PayPalTransactionInfoID) { using (OurCustomDbConnection conn = CreateConnection("UpdateCash")) { conn.CommandText = @"update Cash set PaymentSourceID = @PayPalTransactionInfoID where id = @cashID"; conn.AddParam("@PayPalTransactionInfoID", PayPalTransactionInfoID); conn.ExecuteNonQuery(); } } So I thought hmm, maybe change the names to these so that they are now unique and somewhat explain what field its updating: UpdateCashOrderID UpdateCashTransactionInfoID ok but that's not really very good names. And I can't go too generic, for example: UpdateCashTransaction(int cashID, paypalTransactionID) What if we have different types of transactionIDs that the cash record holds besides just the paypalTransactionInfoID? such as the creditCardInfoID? Then what? Transaction doesn't tell me what kind. And furthermore what if you're updating 2 fields so you have 2 params next to the cashID param: UpdateCashTransaction(int cashID, paypalTransactionID, someOtherFieldIWantToUpdate) see my frustration? what's the best way to handle this is my boss doesn't like my first route?

jQuery function execute on Button Click and Enter/Return (key)

I'm trying to create a little search box that allows you to search Twitter based on the keyword you enter in the input field. While it's work, it only works if you press the Submit button. I would also like to be able to press the Enter or Return key to initiate the search. I've tried using the .sumbit function and wrapping my input around a form element with no success. Any insight would be greatly appreciate!

dynamically bound elements don't subscribe to CSS rules

- by user961627

I'm using ajax to dynamically populate a menu. The problem is the dynamically created elements do not follow the CSS rules, although they're created with the right classname. This is surprising. Here's my HTML: <div id='menu1'> <ul class='menu'> <?php $sql = /// /* some sql string, which works */ $result = mysql_query($sql); while($row = mysql_fetch_array( $result )) { $prod_id = $row['product_id']; $prod_name = $row['product_name']; echo "<li data-title='$prod_id' class='menu1_item'>".$prod_name."</li> "; } ?> </ul> </div> <div id='menu2'> <ul class='menu'> </ul> </div> <div id='menu3'> <ul class='menu'> </ul> </div> Here's my jquery: $(".menu1_item").click( function() { $.ajax({ type: "POST", data: { m: '2', id: $(this).attr('data-title') }, url: "fetch_designs.php", success: function(msg){ if (msg != ''){ $("#menu2").html(msg).show(); $(".menu2_item").bind('click',function() { $.ajax({ type: "POST", data: { m: '3', id: $(this).attr('data-title') }, url: "fetch_designs.php", success: function(msg){ if (msg != ''){ $("#menu3").html(msg).show(); } } }); //end menu2 click }); //end if } //end success } }); //end menu1 click }); My CSS is as follows: ul.menu li { cursor:pointer; list-style: none; } #menu1, #menu2, #menu3 { margin:50px; position:relative; display:block; float:left; } .menu1-item .menu2-item .menu3-item { padding:4px; background-color:lightgray; color:black; cursor:pointer; }

Rails, Edit page update in a window

- by Mike

I have my code working so that I have a table of businesses. There's a pencil icon you can click on the edit the business information. The edit information comes up in a partial inside of a modal pop up box. The only problem is that once they make the changes they want and click update, it sends them to the 'show' page for that business. What I want to happen is have the pop up box close and have it update the information. This is my update function in my controller. def update @business = Business.find(params[:id]) respond_to do |format| if @business.update_attributes(params[:business]) flash[:notice] = 'Business was successfully updated.' format.html { redirect_to(business_url(@business)) } format.js else format.html { render :action => "edit" } format.xml { render :xml => @business.errors, :status => :unprocessable_entity } end end end I tried following railscast 43 and i created an .rjs file but I couldn't get that to work at all. My update was still taking me to the show page. Any help would be appreciated. EDIT: Added some more code. <% form_for(@business) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> ... <%= f.label :business_category %><br /> <%= f.select :business_category_id, @business_categories_map, :selected => @business.business_category_id %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> This is my form inside of my edit page which is being called through the index in a pop up by: <div id="popupEdit<%=h business.id %>" class="popupContact"> <a class="popupClose<%=h business.id %>" id="popupClose">x</a> <% if business.business_category_id %> <% @business = business %> <%= render "business/edit" %> <% end %> </div>
