• Ajax problem not displaying data using multiple javascript calls...

  - by Ronedog

  I'm writing an app that uses ajax to retrieve data from a mysql db using php. Because of the nature of the app, the user clicks an href link that has an "onclick" event used to call the javascript/ajax. I'm retrieving the data from mysql, then calling a separate php function which creates a small html table with the necessary data in it. The new table gets passed back to the responseText and is displayed inside a div tag. The tables only have around 10-20 rows of data in them. This functionality is working fine and displays the data in html form exactly as it needs to be on the page. The problem is this. the HREF "onclick" event needs to run multiple scripts one right after the other. The first script updates the "existing" data and inside the "update_existing" function is a call to refresh a section of the page with the updated HTML from the responseText. Then when that is done a "display_html" function is called which also updates a different section of the page with it's newly created HTML table. The event looks like this: Update This string gets built dynamically using php with parameters supplied, but for this example I simply took the parameters out so it didn't get confusing. The "update_existion() function actually calls the display_html() function which updates a section of the page as needed. I need to update a different section of the page on the same click of the mouse right after the update, which is why I'm calling the display_html() again, right after it. The problem is only the last call is being updated on my screen. In other words, the 2nd function call "display_html()" executes and displays the refreshed data just fine, but the previous call to update_existing() runs and updates the database properly, but doesn't display on the screen unless I press the browsers "refresh" button, which of course displays the new data exactly how I want it to, but I don't want the users to have to press the "refresh" button. I tried adding multiple "display_html() calls one right after the other, separating all of them with the semicolon and learned that only the very last function call actually refreshed the div element on the html page with the table information, although all the previous display_html() calls worked, they couldn't be seen on the page without a refresh of the browser. Is this a problem with javascript, or the ajax call, or is this a limitation in the DOM that only allows one element to be updated at a time. The ajax call is asynchroneous, but I've tried both, only async works period. This is the same in both Firefox and Internet Explorer Any ideas what's going on and how to get around it so I can run these multiple scripts?

• jQuery scrollTo plugin to scroll screen to div wouldn't work, why?

  - by Michael Mao

  Hi all: I am working on a web application, whose mock-up page can now be found at: our server If you click on the blue title "step1" and then choose the option of "delivery to address", a form will show up using jQuery ajax load. No problem for this. Click on the "venue" radio button will take you to another form, no problem for this as well. If you scroll down a bit, you can see a textarea, top of that you can see a link called "what's this?". Click on it and the textarea shall be filled with sample words. The problem is, after clicking on the link, the webpage automatically scrolls to the top section. What I want is to keep the textarea to the center of screen after link is clicked. I am trying to use a jQuery plugin called "scrollTo", which can be found here From its demo page I can tell is what I want. And here is my code to try using it: function reloadDeliveryForm() { $('#deliveryForm').load('./ajax/deliveryToVenueForm.html', function(response, status, xhr) { if (status == "error") { $.prompt("Sorry but there was an error, please try again.<br />" + "If same error persists, please report to webmaster."); } else //deliveryForm loaded successfully { validateDeliveryForm(); $("#delivery_special").elastic(); $('#special_conditions_tip').click(function() { console.log("start filling"); fillTextareaWithExample(); console.log("end filling"); $.scrollTo('#delivery_special'); console.log("end scrolling"); }); } }); } From Firebug output I can tell the scrollTo function is called, but doesn't work. I've switched jQuery back to version 1.3.2, which is used on the demo page of the plugin, but that wouldn't help, either. Is there a problem with my coding? Which technique would you use to resolve this problem? Any suggestion is much appreciated.

• php $_FILES error code returning an unexpected error

  - by EmmyS

  I have some code that allows users to upload multiple files at once. It was never getting to a specific point after the upload, so I put in an echo to test for the value of the error code, and it's returning a value that I'm not sure I understand. Here's the code: $tmpTarget = PCBUG_UPLOADPATH; foreach ($_FILES["attachments"]["error"] as $key => $error) { if ($error == UPLOAD_ERR_OK) { $tmp_name = $_FILES["attachments"]["tmp_name"][$key]; $name = str_replace(" ", "_", $_FILES["attachments"]["name"][$key]); move_uploaded_file($tmp_name, "$tmpTarget/$name"); @unlink($_FILES["attachments"]["tmp_name"][$key]); } else { $errorFlag = true; echo "error = $error"; exit; } } The code that creates the attachments field looks like this: for($i=1; $i<=$max_no_img; $i++){ echo "<input type=file name='attachments[]' class='bginput'><br />"; } where $max_no_img is a variable set further up in the code, and PCBUG_UPLOAD path is a constant defined in an included file. Here's what's confusing: after I submit my form, I go and look in my uploads directory, and the files I've selected through the form are there - they uploaded correctly. However, the code is jumping into the else clause and $error is returning 4, which the php manual indicates means that no file was uploaded. Any ideas? The files very clearly are getting where they're supposed to. Is there some other definition of "uploaded" that isn't happening?

• jQuery Colorbox Iframe and Selector

  - by Joker

  I have this: $("a.money").colorbox({href:$("a.money").attr("href")+" div#content"}); Which opens an overlay but only of the content within the #content selector. If I add iframe:true, this will no longer work. Is there a way to get it to work with an iframe? Edit: The closest I could get it to work was by doing this: $("a.money").colorbox({iframe:true, width:700, height:425, onComplete: function() { alert('test'); $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); Although without the alert it doesn't appear to work, I looked into that and I think I need to use .live(), which led me to trying this: $('a.money').live('click', function() { url = this.href; // this is the url of the element event is triggered from $.fn.colorbox({href: url, iframe:true,width:700, height:425, onComplete: function() { $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); return false; }); Didn't work, I still needed to add an alert to make it work. In case you might be wondering what I'm trying to do. The webpage is loaded in the iframe, with all the elements in the #container, so that includes #header, #sidebars, but I only want to show the #content inside the iframe. However, this led me to another problem I realized. Assuming I got this to work without the alert, it will only work for that initial page. For example, if I loaded up a form in the iframe, after submitting the form, I would once again see the whole layout instead of just the #content portion. Is it possible to continue only showing the #content portion of the page upon further navigation?

• Retrieval of Single Entity + Ria Services

  - by Oliver

  Hi there, I am reading and doing some RnD on RIA as a solution for a new Silverlight project. I have read alot of the documentation and decided to do a small mockup of a system using .Net RIA Services. I want to know how to get a Single Entity from the Domain Service? example: I want to get a person and populate a form: public Person GetSinglePerson() { return new Person { ID = 4, FirstName = "Cyanide", LastName = "Happiness", Status=3 }; } Say I use the the DomainDataSource: <riaControls:DomainDataSource x:Name="source2" QueryName="GetSinglePersonQuery" AutoLoad="True"> <riaControls:DomainDataSource.DomainContext> <web:DataContext/> </riaControls:DomainDataSource.DomainContext> </riaControls:DomainDataSource> This only returns a EntityCollectionView? How do I bind for example in a form to properties that are in the Person Class? Like: <TextBox Text="{Binding FirstName, ElementName=source2}"/> Everything seems to come back as IEnumerable or as CollectionViews (like the DATA binding in the samples) which aren't useful for a single entity. I want a single persons entry, why do I want a CollectionView in which I cannot access properties directly. I have also use the: LoadOperation<Person> oLoadOperation = oDataContext.Load(oDataContext.GetSinglePersonQuery()); I am very close to giving up on this RIA idea and just going with a normal WCF service as it is more predictable and manageable at this stage.

• Should a Stack have a maximum size?

  - by Sotirios Delimanolis

  I'm practicing my knowledge of ADTs by implementing some data structures, even if most already exist. With Stacks, a lot of books and other documentation I've read talk about the stack throwing an error when you try to add an element but the stack is full. In a java implementation (or any other), should I specifically keep track of a maximum stack size (from constructor), check to see if that size is reached, and throw an overflow exception if it is? Or is not such a big deal?

• Which is a good way to maintain resources for Internationalization in .Net

  - by ashtee

  I have thought of three approaches to create and maintain resources in .Net projects for WinForms using Visual Studio 2008. (I am sure there should be more than three ways.) I need to decide on one before starting to implement internationalization for our product. Have individual sets of resource files (resx) for each windows form or piece of UI (a custom control) in each .net project. These are auto generated by Visual Studio when Localizable property is set to true in the form or control properties. Have one resource file per .net project. This is added manually and updated manually with the resource strings and messages. Have one resource manager project that has resources for all the components for a set of .net projects. Personally, I do not like the first approach as it creates numerous resources files. The only advantage we get in this approach is that we do not need to set text in UI elements manually. I like second and third approach as they are easy to maintain and there is only one set of resources that you need to handle. So no duplication of strings and messages. Easy for the translators also. What are your thoughts? Please share.

• JQuery Autocomplete plugin not working with JQuery 1.4.1

  - by Russ Clark

  I've been using the JQuery Autocomplete plugin with JQuery version 1.3.2, and it has been working great. I recently updated JQuery in my project to version 1.4.2, and the Autocomplete plugin is now broken. The JQuery code to add items to a textbox on my web page doesn't seem to be getting called at all. Does anyone know if the JQuery Autocomplete plugin is incompatible with JQuery version 1.4.2, and if there is a fix for this problem? Here is some sample code I've built in an ASP.Net web site (which works fine if I change the JQuery file to jquery-1.3.2.js, but nothing happens using jquery-1.4.2.js): <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <script type="text/javascript" src="js/jquery-1.4.2.js" ></script> <script type="text/javascript" src="js/jquery.autocomplete.js" ></script> <script type="text/javascript"> $(document).ready(function() { var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $(':input:text:id$=sapleUser').autocomplete(data); }); </script> </head> <body> <form id="form1" runat="server"> API Reference: <input id="sapleUser" autocomplete="off" type="text" runat="server" /> (try "C" or "E") </form> </body> </html>

• Show cue banner for wpf ComboBox with grouping

  - by Adam Duston

  I have a ComboBox in my WPF form: <ComboBox Margin="75,0,15,102" Name="videoFormatCombo" Height="23" VerticalAlignment="Bottom" DataContext="{StaticResource GroupedVideoFormats}" ItemsSource="{Binding}" ItemTemplate="{StaticResource VideoFormatTemplate}"> <ComboBox.GroupStyle> <GroupStyle HeaderTemplate="{StaticResource GroupHeader}"/> </ComboBox.GroupStyle> </ComboBox> As you might be able to guess, GroupedVideoFormats is a CollectionViewSource with grouping. I need to get a cue banner to display for this ComboBox. I've attempted the solution that is (very verbosely) outlined in this blog post, but it will not work for a ComboBox with grouped data. The two solutions outlined in superfluousprefixhttp://stackoverflow.com/questions/2548757/how-can-the-blank-space-in-a-c-combobox-be-filled-as-a-hint-for-the-user are for Windows Forms ComboBoxes only, and won't work with WPF. If it would help to see all the original source, this particular form is on github: superfluousprefixhttp://github.com/8planes/mirovideoconverter/blob/master/MSWindows/Windows/FileSelect.xaml . It's an open-source project, so the entire project is on github: superfluousprefixhttp://github.com/8planes/mirovideoconverter/tree/master/MSWindows . Thank you for any advice! Adam P.S. stackoverflow wouldn't let me make more than one anchor tag in my post, hence the long urls with the superfluous prefix. Sorry!

• javascript to reference input IDs in php loop and pass values back to same input ID

  - by Smudger

  I have a form which is essentially an autocomplete input box. I can get this to work perfectly for a single text box. What I need to do is create unique input boxes by using a php for loop. This will use the counter $i to give each input box a unique name and id. The problem is that the unique value of the input box needs to be passed to the javascript. this will then pass the inputted data to the external php page and return the mysql results. As mentioned I have this working for a single input box but need assistance with passing the correct values to the javascript and returning it to correct input box. existing code for working solution (first row works only, all other rows update first row input box) <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function lookup(inputString) { if(inputString.length == 0) { // Hide the suggestion box. $('#suggestions').hide(); } else { $.post("autocompleteperson.php", {queryString: ""+inputString+""}, function(data){ if(data.length >0) { $('#suggestions').show(); $('#autoSuggestionsList').html(data); } }); } } // lookup function fill(thisValue) { $('#inputString').val(thisValue); setTimeout("$('#suggestions').hide();", 200); } </script> </head> <body> <form name="form1" id="form1" action="addepartment.php" method="post"> <table> <? for ( $i = 1; $i <=10; $i++ ) { ?> <tr> <td> <? echo $i; ?></td> <td> <div> <input type="text" size="30" value="" id="inputString" onkeyup="lookup(this.value);" onblur="fill();" /> </div> <div class="suggestionsBox" id="suggestions" style="display: none;"> <img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" /> <div class="suggestionList" id="autoSuggestionsList"> &nbsp; </div> </div> </td> </tr> <? } ?> </table> </body> </html> code for autocompleteperson.php is: $query = $db->query("SELECT fullname FROM Persons WHERE fullname LIKE '$queryString%' LIMIT 10"); if($query) { while ($result = $query ->fetch_object()) { echo '<li onClick="fill(\''.$result->fullname.'\');">'.$result->fullname.'</li>'; } } in order to get it to work for all rows, I include the counter $i in each of the file names as below: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function lookup(inputString<? echo $i; ?>) { if(inputString<? echo $i; ?>.length == 0) { // Hide the suggestion box. $('#suggestions<? echo $i; ?>').hide(); } else { $.post("autocompleteperson.php", {queryString: ""+inputString<? echo $i; ?>+""}, function(data){ if(data.length >0) { $('#suggestions<? echo $i; ?>').show(); $('#autoSuggestionsList<? echo $i; ?>').html(data); } }); } } // lookup function fill(thisValue) { $('#inputString<? echo $i; ?>').val(thisValue); setTimeout("$('#suggestions<? echo $i; ?>').hide();", 200); } </script> </head> <body> <form name="form1" id="form1" action="addepartment.php" method="post"> <table> <? for ( $i = 1; $i <=10; $i++ ) { ?> <tr> <td> <? echo $i; ?></td> <td> <div> <input type="text" size="30" value="" id="inputString<? echo $i; ?>" onkeyup="lookup(this.value);" onblur="fill();" /> </div> <div class="suggestionsBox" id="suggestions<? echo $i; ?>" style="display: none;"> <img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" /> <div class="suggestionList" id="autoSuggestionsList<? echo $i; ?>"> &nbsp; </div> </div> </td> </tr> <? } ?> </table> </body> </html> The autocomplete suggestion works (although always shown on first row) but when selecting the data always returns to row 1, even if input was on row 5. I have a feeling this has to do with the fill() but not sure? is it due the the autocomplete page code? or does the fill referencing ThisValue have something to do with it. example of this page (as above) can be found here Thanks for the assistance, much appreciated. UPDATE - LOLO <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function lookup(i, inputString) { if(inputValue.length == 0) { // Hide the suggestion box. $('#suggestions' + i).hide(); } else { $.post("autocompleteperson.php", {queryString: ""+inputString+""}, function(data){ if(data.length >0) { $('#suggestions' + i).show(); $('#autoSuggestionsList' + i).html(data); } }); } } // lookup function fill(i, thisValue) { $('#inputString' + i).val(thisValue); setTimeout("$('#suggestions' + i).hide();", 200); } </script> </head> <body> <form name="form1" id="form1" action="addepartment.php" method="post"> <table> <? for ( $i = 1; $i <=10; $i++ ) { ?> <tr> <td> <? echo $i; ?></td> <td> <div> <input type="text" size="30" value="" id="inputString<?php echo $i; ?>" onkeyup="lookup(this.value);" onblur="fill();" /> </div> <div class="suggestionsBox" id="suggestions<? echo $i; ?>" style="display: none;"> <img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" /> <div class="suggestionList" id="autoSuggestionsList<? echo $i; ?>"> &nbsp; </div> </div> </td> </tr> <? } ?> </table> </body> </html> google chrome catched the following errors: first line on input, second line on loosing focus

• JQUERY Effect highlight, control the Start & End colors

  - by nobosh

  I have the following: $(".notifycell_email_dailydigest").effect('highlight'); The element I want to highlight is over a gray background. Problem is the highlight goes from Yellow to white, and has this ugly slow pause at the end on the white which makes the animation look horrible. How can I modify the highlighy to start with the yellow but end on the gray so it matches the background? Thanks

• jquery performing calculation on dynamically generated elements

  - by user306472

  I have a table made up of a row of 3 input elements: Price, Quanity, and Total. Under that, I have two links I can click to dynamically generate another row in the table. All that is working well, but actually calculating a value for the total element is giving me trouble. I know how to calculate the value of the first total element but I'm having trouble extending this functionality when I add a new row to the table. Here's the html: <table id="table" border="0"> <thead> <th>Price</th><th>Quantity</th><th>Total</th> </thead> <tbody> <tr> <td><input id ="price" type = "text"></input></td> <td><input id ="quantity" type = "text"></input></td> <td><input id ="total" type = "text"></input></td> </tr> </tbody> </table> <a href="#" id="add">Add New</a> <a href="#" id="remove">Remove</a> Here's the jquery I'm using: $(function(){ $('a#add').click(function(){ $('#table > tbody').append('<tr><td><input id ="price" type = "text"></input></td><td><input id ="quantity" type = "text"></input></td><td><input id ="total" type = "text"></input></td></tr>'); }); $('a#remove').click(function(){ $('#table > tbody > tr:last').remove(); }); }); $(function(){ $('a#calc').click(function(){ var q = $('input#quantity').val(); var p = $('input#price').val(); var tot = (q*p); $('input#total').val(tot); }); }); I'm new to jquery so there's probably a simple method I don't know about that selects the relevant fields I want to calculate. Any guidance would be greatly appreciated.

• add text to the choice_label of ChoiceField in Django

  - by pablo

  The ChoiceField creates a select html element and the options show the choice_label which is the _unicode_ of each model object. How can I change the text of the choice_label without modifying _unicode_ ? I have a Product model and I want to show in the options text the product name + price + link to edit. I've searched in fields.py and widgets.py but couldn't find what needed to be changed. Thanks

• Rails fields_for parameters for a has_many relation don't yield an Array in params

  - by user1289061

  I have a model Sensor with has_many and accepts_nested_attributes_for relationships to another model Watch. In a form to update a Sensor, I have something like the following <%= sensor_form.fields_for :watches do |watches_form| %> <%= watches_form.label :label %><br /> <%= watches_form.text_field :label %> <% end %> This is indended to allow editting of the already-created Watches belonging to a Sensor. This call spits form inputs as so: <input name="sensor[watches_attributes][0][label]" ... /> <input name="sensor[watches_attributes][0][id]" ... /> When this gets submitted, the params object in the Sensor controller gets an assoc like "sensor" => { "id"=>"1", "watches_attributes"=> { "0"=>{"id" => "1", "label" => "foo"}, "1"=>{"id" => "2", "label" => "bar"} } } For a has_many, accepts_nested_attributes_for update to work upon the @sensor.update_attributes call, it seems that that attributes key really must map to an Array. From what I've seen in the examples, the combination of has_many, accepts_nested_attributes_for, and sensor_form.fields_for should allow me to pass the resulting params object directly to @sensor.update_attributes and update each related object as intended. Instead the Sensor takes place, with no errors, but the Watch objects are not updated (since "watches_attributes" maps to a Hash instead of an Array?) Have I missed something?

• Canonical resource for forms-based design in ASP.NET MVC?

  - by Robert Harvey

  Is there a resource on the web that describes various form scenarios in ASP.NET MVC, and gives example solutions within a sensible, consistent design philosophy? Examples of such scenarios might be: One-to-many forms, like invoice data-entry forms. Foreign-table forms such as Add New User in a form that requires specifying a user Forms that require dynamic interaction, using Ajax or JSON. Popup forms Forms requiring multiple data records to be input, without postbacks. Note that there is considerable conceptual and technological overlap among these example scenarios. I am aware that there is a vast patchwork quilt of available technologies and examples out there that provide partial solutions and pieces of solutions, such as jQuery Ajax, CSS, and so forth. But I would like guidance in using these technologies in more effective and consistent ways. I am not considering web forms integration with an ASP.NET MVC application; I would still like my applications to be pure MVC. Nor am I, at the moment, considering a paid solution like Telerik. But I would like to know if someone has already done some of the work combining these technologies into a consistent, cohesive whole, that follows a sensible design philosophy. (an open source framework, perhaps?)
