  • Two buttons in a form, Both called

    - by coffeeaddict
    Here's my ASP.NET form. When I click one button it calls both jQuery functions. It's probably a rudimentary HTML question but I'm not sure why: <form id="form1" runat="server"> <div id="testDialog"> </div> <p><input type="button" id="invoke1" value="test 1" /></p> <input type="button" id="invoke2" value="test 2" /> </form> <script type="text/javascript"> $(function() { $("input:invoke1").click(function(){ showSomething("testDialog"); }); $("input:invoke2").click(function(){ showSomething2("test.aspx", options); }); }); </script>

  • piecing together a jquery form mailer

    - by Joel
    Hi guys, My newbieness is shining through here...I managed to piece together a form mailer that works great, but now I need to add two more fields, and I'm at a loss as to how to do it. Over the months, I have commented out some things I didn't need, but now I'm stuck. I borrowed from this tutorial to make the original form: http://trevordavis.net/blog/tutorial/ajax-forms-with-jquery/ But then I cannibalized it to make an email signup form for a newsletter, so the fields I need are: recipient email (me-hard coded in) senders email address subject (hardcoded in) first name and city in the body of the message For my form, I have this: <div> <?php include('verify.php'); ?> <form action="index_success.php" method="post" id="sendEmail" class="email"> <h3 class="register2">Newsletter Signup:</h3> <ul class="forms email"> <li class="name"><label for="yourName">Name: </label> <input type="text" name="yourName" class="info" id="yourName" value=" " /><br> </li> <li class="city"><label for="yourCity">City: </label> <input type="text" name="yourCity" class="info" id="yourCity" value=" " /><br> </li> <li class="email"><label for="emailFrom">Email: </label> <input type="text" name="emailFrom" class="info" id="emailFrom" value="<?= $_POST['emailFrom']; ?>" /> <?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>'; ?> </li> <li class="buttons email"> <button type="submit" id="submit">Send</button> <input type="hidden" name="submitted" id="submitted" value="true" /> </li> </ul> </form> </div> emailcontact.js: $(document).ready(function(){ $("#submit").click(function(){ $(".error").hide(); var hasError = false; var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var emailFromVal = $("#emailFrom").val(); if(emailFromVal == '') { $("#emailFrom").after('<span class="error">You forgot to enter the email address to send from.</span>'); hasError = true; } else if(!emailReg.test(emailFromVal)) { $("#emailFrom").after('<span class="error">Enter a valid email address to send from.</span>'); hasError = true; } var subjectVal = $("#subject").val(); if(subjectVal == '') { $("#subject").after('<span class="error">You forgot to enter your name.</span>'); hasError = true; } var messageVal = $("#message").val(); if(messageVal == '') { $("#message").after('<span class="error">You forgot to enter your city.</span>'); hasError = true; } if(hasError == false) { $(this).hide(); $("#sendEmail li.buttons").append('<img src="/wp-content/themes/default/images/template/loading.gif" alt="Loading" id="loading" />'); $.post("/includes/sendemail.php", //emailTo: emailToVal, { emailFrom: emailFromVal, subject: subjectVal, message: messageVal }, function(data){ $("#sendEmail").slideUp("normal", function() { $("#sendEmail").before('<h3 class="register2">Success!</h3><p class="emailbox">You are on the Newsletter email list.</p>'); }); } ); } return false; }); }); sendmail.php: <?php $mailTo = $_POST['emailTo']; $mailFrom = $_POST['emailFrom']; $subject = $_POST['yourName']; $message = $_POST['yourCity']; mail('[email protected]','Rattletree Newsletter', 'Name='.$subject.

  • Rendering partial for table row with form_tag is getting crazy!

    - by xopht
    I have 23(column)x6(row) table and change the row with link_to_remote function. each tr tag has its own id attribute. change link call change action and change action changes the row using render function wit partial. _change.html.erb <td id="row_1">1</td> . . omitted . . <td id="row_23">23</td> link_to_remote function <%= link_to_remote 'Change', :update => 'row_1', :url => change_path %> change action def change logger.debug render :partial => 'change' end If I coded like above, everything work okay. This means all changed-columns are in one row. But, if I wrap partial code with *form_for* function like below... <% form_for 'change' do %> <td id="row_1">1</td> . . omitted . . <td id="row_23">23</td> <% end %> Then, one column located in one row and that column is the first column. I've looked up the log file, but it was normal html tags. What's wrong?

  • Html.ActionLink in a button

    - by Pomster
    I Am trying to connect to a method in my controller, with a button. I can connect though this link: @Html.ActionLink("Print", "Print", new { id = Model.SalesContractId}) But i Don't want a link, i want my button on my dialog to do it. I have tried the following: $('#btnDialogPrint').click(function () { location.href = '<%= Url.Action("Print", "Print", new { id = Model.SalesContractId}) %>'; }); But it just redirect me to a page that say bad request. namespace Contract.Controllers { public class ContractController : Controller { CompassEntities db = new CompassEntities(); public ActionResult Print(int id) { return View(""); // This can be removed and Print code may be added } Don't worry about the code inside i will get to that once i get inside this method. Could i maybe attach a link here? <input type="button" value="Print" id="btnDialogPrint" />

  • How can I improve my select query for storing large versioned data sets?

    - by Jason Francis
    At work, we build large multi-page web applications, consisting mostly of radio and check boxes. The primary purpose of each application is to gather data, but as users return to a page they have previously visited, we report back to them their previous responses. Worst-case scenario, we might have up to 900 distinct variables and around 1.5 million users. For several reasons, it makes sense to use an insert-only approach to storing the data (as opposed to update-in-place) so that we can capture historical data about repeated interactions with variables. The net result is that we might have several responses per user per variable. Our table to collect the responses looks something like this: CREATE TABLE [dbo].[results]( [id] [bigint] IDENTITY(1,1) NOT NULL, [userid] [int] NULL, [variable] [varchar](8) NULL, [value] [tinyint] NULL, [submitted] [smalldatetime] NULL) Where id serves as the primary key. Virtually every request results in a series of insert statements (one per variable submitted), and then we run a select to produce previous responses for the next page (something like this): SELECT t.id, t.variable, t.value FROM results t WITH (NOLOCK) WHERE t.userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') AND t.id IN (SELECT MAX(id) AS id FROM results WITH (NOLOCK) WHERE userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') GROUP BY variable) Which, in this case, would return the most recent responses for the variables "internat", "veteran", and "athlete" for user 2111846. We have followed the advice of the database tuning tools in indexing the tables, and against our data, this is the best-performing version of the select query that we have been able to come up with. Even so, there seems to be significant performance degradation as the table approaches 1 million records (and we might have about 150x that). We have a fairly-elegant solution in place for sharding the data across multiple tables which has been working quite well, but I am open for any advice about how I might construct a better version of the select query. We use this structure frequently for storing lots of independent data points, and we like the benefits it provides. So the question is, how can I improve the performance of the select query? I assume the nested select statement is a bad idea, but I have yet to find an alternative that performs as well. Thanks in advance. NB: Since we emphasize creating over reading in this case, and since we never update in place, there doesn't seem to be any penalty (and some advantage) for using the NOLOCK directive in this case.

  • Preventing entire JOINed MYSQL query from failing when one field is missing within a WHERE clause

    - by filip o
    I am doing a couple of joins with a variable in the WHERE clause. I'm not sure if I am doing everything as efficiently as I could, or even using the best practices but my issue is that half my tables have data for when tableC.type=500, and the other half don't resulting in the entire query failing. SELECT tableA.value1 , tableB.value2, tableC.value3 FROM tableA JOIN tableB ON tableB.id=tableA.id JOIN tableC ON tableC.id=tableB.id WHERE tableA.category=$var && tableC.type=500; What I would like to happen is to still get tableA.value1 and tableB.value2 even if there is no field in tableC with a type=500. any thoughts? i'm totally stumped as how to approach this...

  • Hiding and Showing Elements with JavaScript

    - by user1658756
    I have an arrow on my site that I'd like if onclick, it hides one element, and shows another. Hitting it again, will hide the element that was shown and show the element that was hidden. Is that possible to do without jQuery? For example, I have <div id="arrow"><a href="#">?</a></div> <div id="ad"></div> <div id="description">Hidden</div> <div id="nav">Also Hidden</div> So at first, the ad is showing, and then one you've clicked the arrow, I'd like the ad to hide, and then unhide the description and nav.

  • jquery focusin() and preventing bubbling.

    - by DA
    I'm showing a div via an onclick event. If you click outside the div, I want to hide it. To do so, I'm binding a one time click event on the body: $('body').one('click.myDivPopup', function(e) { ...close my div... }); Within the div itself, I tell it to not propogate events so that actually clicking within the div won't trigger a click on the body: $myDiv.click(function(e){e.stopPropagation()}); This works fine as intended. I also want to hide the div if one tabs out of the div. My thinking was that in that scenario, I could use a focusin event on the body: $('body').one('focusin.myDivPopup', function(e) { ...close my div... }); Again, I don't want the events to bubble out of the div itself, so added this: $myDiv.focusin(function(e){e.preventDefault()}); This does NOT work. Changing focus within elements within myDiv triggers the focusin event on the body. Is this maybe a bug in jQuery? If so is there a better way to accomplish this?

  • What are the hibernate annotations used to persist a Map with an enumerated type as a key?

    - by Jason Novak
    I am having trouble getting the right hibernate annotations to use on a Map with an enumerated class as a key. Here is a simplified (and extremely contrived) example. public class Thing { public String id; public Letter startLetter; public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } public enum Letter { A, B, C, D } Here are my current annotations on Thing @Entity public class Thing { @Id public String id; @Enumerated(EnumType.STRING) public Letter startLetter; @CollectionOfElements @JoinTable(name = "Thing_letterFrequencies", joinColumns = @JoinColumn(name = "thingId")) @MapKey(columns = @Column(name = "letter", nullable = false)) @Column(name = "count") public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } Hibernate generates the following DDL to create the tables for my MySql database create table Thing (id varchar(255) not null, startLetter varchar(255), primary key (id)) type=InnoDB; create table Thing_letterFrequencies (thingId varchar(255) not null, count double precision, letter tinyblob not null, primary key (thingId, letter)) type=InnoDB; Notice that hibernate tries to define letter (my map key) as a tinyblob, however it defines startLetter as a varchar(255) even though both are of the enumerated type Letter. When I try to create the tables I see the following error BLOB/TEXT column 'letter' used in key specification without a key length I googled this error and it appears that MySql has issues when you try to make a tinyblob column part of a primary key, which is what hibernate needs to do with the Thing_letterFrequencies table. So I would rather have letter mapped to a varchar(255) the way startLetter is. Unfortunately, I've been fussing with the MapKey annotation for a while now and haven't been able to make this work. I've also tried @MapKeyManyToMany(targetEntity=Product.class) without success. Can anyone tell me what are the correct annotations for my letterCounts map so that hibernate will treat the letterCounts map key the same way it does startLetter?

  • validation before ajax form submission

    - by ZX12R
    How do i introduce validation before remote_form_for submits? I have javascript function called validateForm(). I am able to call it before the AJAX request process. I tried to use return false and event.preventDefault. But there seems to be no effect. Here is what my code looks like <% remote_form_for :customer, :update =>"uxScreenLoaderDiv", :url => {:action => "login", :controller => "site"}, :html => {:id => "uxLoginForm"}, :onsubmit => "validateForm(event)" do |f| %> User name : <%= f.text_field "uxUserName", :class => "TextBox", :style => "width:100px;" %>&nbsp;* &nbsp;Password : <%= f.password_field "uxPassword", :class => "TextBox", :style => "width:100px;" %>&nbsp;* <%= f.submit "Go!", :class => "Button-Simple", :id => "uxSubmitButton" %> <% end %> the javascript function is simple as follows function validateForm(event){ return false; //event.preventDefault(); }

  • Forms blank when rendering a partial when using a collection of objects. Help!

    - by dustmoo
    Alright, I know my title is a little obscure but it best describes the problem I am having. Essentially, I have a list of users, and want to be able to edit their information in-line using AJAX. Since the users are showing up in rows, I am using a partial to render the data and the forms (which will be hidden initially by the ajax), however, when the rows are rendered currently only the last item has it's form's fields populated. I suspect this has something to do with the fact that all the form fields have the same id's and it is confusing the DOM. But I don't know how to make sure the id's are unique. Here is a small example: In my view: <%= render :partial => 'shared/user', :collection => @users %> My partial (broke down to just the form) note that I am using the local variable "user" <% form_for user, :html => {:multipart => true} do |f| -%> <%= f.label :name, "Name*" %> <%= f.text_field :title, :class => "input" %> <%= f.label :Address, "Address" %> <%= f.text_field :address, :class => "input" %> <%= f.label :description, "Description*" %> <%= f.text_area :description, :class => "input" %> <% end -%> When the html is rendered each form has a unique id (for the id of the user) but the elements themselves all have the same id, and only the last user form is actually getting populated with values. Does anyone have any ideas?? :) Thanks in advance!

  • How to get ImageButton size within Android GridView?

    - by wufoo
    I'm subclassing ImageButton in order to draw lines on it and trying to figure out where the actual button coordinates are within my gridview. I am using onGlobalLayout to setup Top, Bottom, Right and Left, but these seem to be for the actual "square" within the grid, and not the actual button (see image). The purple lines are drawn in myImageButton.onDraw() using coords gathered from myImageButton.onGlobalLayout(). I thought these would be for the button, but they seem to be from something else. Not sure what. I'd like the purple lines to match the outline of the button so the lines I draw appear on the button and not just floating out in the LinearLayout somewhere. The light blue is the background color of the vertical LinearLayout holding the Textview (for the number) and myImageButton. Any way to get the actual button size? XML Layout: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/lay_cellframe" android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="fill_vertical|fill_horizontal" android:orientation="vertical" > <TextView android:id="@+id/tv_cell" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="2dp" android:gravity="center" android:text="TextView" android:textSize="10sp" /> <com.example.icaltest2.myImageButton android:id="@+id/imageButton1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_margin="0dp" android:adjustViewBounds="false" android:background="@android:drawable/btn_default" android:scaleType="fitXY" android:src="@android:color/transparent" /> </LinearLayout> </FrameLayout> myImageButton.java public myImageButton (Context context, AttributeSet attrs) { super (context, attrs); mBounds = new Rect(); ViewTreeObserver vto = this.getViewTreeObserver (); vto.addOnGlobalLayoutListener (ogl); Log.d (TAG, "myImageButton"); } ... OnGlobalLayoutListener ogl = new OnGlobalLayoutListener() { @Override public void onGlobalLayout () { Rect b = getDrawable ().getBounds (); mBtnTop = b.centerY () - (b.height () / 2); mBtnBot = b.centerY () + (b.height () / 2); mBtnLeft = b.centerX () - (b.width () / 2); mBtnRight = b.centerX () + (b.width () / 2); } }; ... @Override protected void onDraw (Canvas canvas) { super.onDraw (canvas); Paint p = new Paint (); p.setStyle (Paint.Style.STROKE); p.setStrokeWidth (1); p.setColor (Color.MAGENTA); canvas.drawCircle (mBtnLeft, mBtnTop, 2, p); canvas.drawCircle (mBtnLeft, mBtnBot, 2, p); canvas.drawCircle (mBtnRight, mBtnTop, 2, p); canvas.drawCircle (mBtnRight, mBtnBot, 2, p); canvas.drawRect (mBtnLeft, mBtnTop, mBtnRight, mBtnBot, p); }

  • Windows Service Start-Up Error 1069

    - by Gavin
    Hello, I am installing a new windows service coded in C# on a server. I installed the service fine on the server, but once i manually start up the service on a server, with the same login credentials that our other services use, i get the fatal error message notification: "Could not start the %service name% on Local Computer. Error 1069: The Service did not start due to a logon failure." I looked in the event log and i got a 7038 and 7000 event id error in that order. 7038 event id message: "The %service name% service was unable to log on as %login% with the currently configured password due to the following error: Logon failure: unknown user name or bad password. To ensure that the service is configured properly, use the Services snap-in in Microsoft Management Console (MMC)." 7000 event id message: "The %service name% service failed to start due to the following error: The service did not start due to a logon failure. " I have other services that are using the same exact login account and they work fine. Is there something simple I could be missing? Thanks

  • problem with "select new Object ... join ... where"

    - by jacob
    Hi, I'm having a problem with an HQL query Three classes ClassOne is my BusinessObject public class ClassOne { private int id; private int status; private Set<ClassTwo> classTwos; + other fields/getters/setters/constructor etc } ClassTwo is referenced in a set of ClassOne and is kind of the history of an object of ClassOne public class ClassTwo { private int id; private int oldStatus; private int newStatus; private String message; //+ getters/setters/constructor etc } ClassThree is my DTO/VO with just one classTwo (not the whole history) public class ClassThree { private int id; private int status; private ClassTwo classTwo; public ClassThree(int pId, int pStatus, ClassTwo pClassTwo) { id=pId; status=pStatus; classTwo=pClassTwo; } //+ getters/setters etc } Now I'd like to create an HQL query like this: I'd like to get all objects of ClassThree with a certain status and if it exists the newest ClassTwo with a certain newStatus. For example: I'd like to get all the DTOs (ClassThree) of ClassOne whose status is now 1, but earlier in their history it has been 2 and I'd like to have the latest ClassTwo object which has 2 as newStatus. SELECT new ClassThree(c1.id, c1.status, c2) FROM ClassOne c1 LEFT JOIN c1.classtwos c2 (...) and (...) is where I don't know what to do, I'm not even sure if it's a join / join fetch Looked around and tried quite a lot already, but no clue. Especially with the join fetch I get some Hibernate errors like org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list. Fetching the BusinessObject like that is no problem SELECT distinct(c1) FROM ClassOne c1 LEFT OUTER JOIN FETCH c1.classtwos c2 and I get the ClassTwos as my field. Thanks in advance, Jacob P.S.: One thing might be important, ClassTwo has no reference to ClassOne!!

I can get this to work: foreach ($piggies_array as $key => $value) { $id = $value[0]->id; $redirect_url = $value[0]->redirect_url; } Not unsurprisingly, it's only echoing the first value of those variables, but no matter what I try I cannot get it to loop through: $value->redirect_url; $value=>redirect_url; I would appreciate any help.

  • object references an unsaved transient instance

    - by developer
    Hi, I have 2 tables, user and userprofile, both with almost identical fields. user table references userprofile table by primary key ID. My requirement is that on click of a button I need to dump user table record to userprofile table. Now for a particular user table, if there is a corresponding userprofile entry, I am successfully able to dump the data, but if there is no record in userprofile table then I need to create a new record by dumping all the data. My problem is that I am able to update the data when the record is present in userprofile table, but in the case wherein I have to create a new record I get the below error "object references an unsaved transient instance - save the transient instance before flushing". `<class name="User"> <id name="ID" type="Int32"> <generator class="native" /> </id> <many-to-one name="Pid" class="UserProfile" /> </class>` UserProfile is another table and Pid above references the Primary key ID of UserProfile table.

  • jquery: How can I trigger click() without editing the element state?

    - by user280381
    I need to trigger a click function assigned to a checkbox, but without actually changing it's checked state (which click() does). Scenario: I have a form with several checkboxes that when selected reveal a textarea. This works fine, but I also need to call the click() function on $(document).ready() My code is below, please note I have very limited access to changing the generated html. I have an object (admin_panels) which will store each checkbox and the texarea it should bring up. var admin_panels = {"checkbox-id" : "textarea-id"}; $(document).ready(function(){ for (var elem in admin_panels) { $("#" + elem).click(admin_slide); // $("#" + elem).click(); } }) function admin_slide() { if ($(this).is(":checked")) { $("#" + admin_panels[this.id] + "-wrapper").slideDown(); }else{ $("#" + admin_panels[this.id] + "-wrapper").slideUp(); } } Thanks

Html mark up is below: <div> <!-- Photos --> <fieldset> <legend>PropertyPhotos</legend> <div class="upload-box" id="upload-box-1"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_1" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File1) @Html.ValidationMessageFor(model => model.File1) </div> </div> <div class="upload-box" id="upload-box-2"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_2" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File2) @Html.ValidationMessageFor(model => model.File2) </div> </div> <div class="upload-box" id="upload-box-3"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_3" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File3) @Html.ValidationMessageFor(model => model.File3) </div> </div> </fieldset> </div> The Jquery to show preview and then display the next "upload-box" is as follows: <script type="text/javascript"> $(document).ready(function () { // show first box $("#upload-box-1").fadeIn(); //Get current & next step index var stepNum = $('div.upload-box').attr('id').replace(/[^\d]/g, ''); var nextNum = parseInt(stepNum)+1; //Get the preview image tag var preview = $('#preview_'+stepNum); //Load preview on file tag change and display second upload-box $('#File'+stepNum).change(function (evt) { var f = evt.target.files[0]; var reader = new FileReader(); if (!f.type.match('image.*')) { alert("The selected file does not appear to be an image."); return; } reader.onload = function (e) { preview.attr('src', e.target.result); }; reader.readAsDataURL(f); //Show next upload-box $("#upload-box-" + nextNum).fadeIn(); }); }); </script> However, this code only first for the first time ... i.e. on selecting a file - It shows a preview and then shows the next "upload-box". However, when I browse using the second file it doesn't show any preview. From what I have ready, I need to close the Jquery function so that it can be initialised again but I am not sure how to do that. Any help will be grateful.

  • How does Zend_Db_Table_Select work?

    - by jwhat
    I'm trying to figure out how to use Zend_Db_Table_Abstract correctly. I want to return just the name column from my query. Can you please explain what's wrong with the following code? class Model_DbTable_Foo extends Zend_Db_Table_Abstract { protected $_name = 'foo'; public function getFooById($id) { $select = $this->select(true)->columns('name')->where('id=' . $id); $row = $this->fetchRow($select); print_r($row->toArray()); } }
