• How to get value of a input field in Javascript

  - by gaurav.mishra280295

  I am using valums-file-uploader plugin. It allows me to upload files using ajax. I have a problem with it. I have the following script- <input type="text" id="Gaurav" name="Gaurav" /> <script src="fileuploader.js" type="text/javascript"></script> <script> function createUploader(){ var uploader = new qq.FileUploader({ element: document.getElementById('file'), action: 'do-nothing.php', params:{param: document.getElementById('Gaurav').value}, allowedExtensions: ['jpg', 'jpeg', 'png', 'gif'], minSizeLimit: 1, debug: false }); } // in your app create uploader as soon as the DOM is ready // dont wait for the window to load window.onload = createUploader; </script> In it, I want to set the value of param entered by the user. The code is working properly for default value of Gaurav, but didn't work for user inputted value.

• Rails 3 get raw post data and write it to tmp file

  - by Andrew

  I'm working on implementing Ajax-Upload for uploading photos in my Rails 3 app. The documentation says: For IE6-8, Opera, older versions of other browsers you get the file as you normally do with regular form-base uploads. For browsers which upload file with progress bar, you will need to get the raw post data and write it to the file. So, how can I receive the raw post data in my controller and write it to a tmp file so my controller can then process it? (In my case the controller is doing some image manipulation and saving to S3.) Some additional info: As I'm configured right now the post is passing these parameters: Parameters: {"authenticity_token"=>"...", "qqfile"=>"IMG_0064.jpg"} ... and the CREATE action looks like this: def create @attachment = Attachment.new @attachment.user = current_user @attachment.file = params[:qqfile] if @attachment.save! respond_to do |format| format.js { render :text => '{"success":true}' } end end end ... but I get this error: ActiveRecord::RecordInvalid (Validation failed: File file name must be set.): app/controllers/attachments_controller.rb:7:in `create'

• How come jQuery can't remove this element?

  - by George Edison

  I have a table like this: <table id='inventory_table'> <tr id='no_items_avail'> <td> There are no items in the database. </td> </tr> </table> And I want to get rid of it with jQuery like this: $('#inventory_table tbody tr#no_items_avail').remove(); However it doesn't seem to be working at all. What am I doing wrong? Edit: Also, the row above was originally inserted into the DOM with another jQuery call: $('#inventory_table tbody').append("<tr id='no_items_avail'....... If that helps. And, running: alert($('#no_items_avail').text()); yields "There are no items in the database." as expected.

• Colspan in IE7/8 not respected

  - by Stefan Kendall

  The DOM looks like this: <table> <tr> <td>a</td>...<td>g</td> </tr> <tr> <td colspan="3"> <table> ... </table> </td> </tr> <tr> <td></td>...<td></td> </tr> </table> Any idea why this wouldn't work in IE? I tried setting width:auto on the TD holding the inner table, and table-layout:fixed isn't viable because the tabular data is generated dynamically. What could be going wrong?

• Changing content of HTMLDocument displayed in a JTextPane

  - by kayahr

  I'm displaying some tables as HTML code (rendered by a Freemarker template) with a JTextPane. I also have some HTML links in this HTML output which can be used to interact with the values of the table (For example "Delete a row" and stuff like this). Currently I always recreate the whole HTML output on each change and replace the whole document in the JTextPane with the new one. This is getting really slow and the JTextPane always changes the scroll position when I do this. Is it possible to change only parts of the HTML code during runtime without replacing the whole document? In a real browser I would use the DOM and do something like document.getElementById("price").innerHTML = "$123.44". Is something like that possible with the HTMLDocument in a JTextPane?

• Does XercesC contain an extensive logic of XMLSchema validation?

  - by seas

  Tried to implement a small XML validation tool with XercesC. For some reason I cannot use existing validators right from the box - I need some preprocessing and would like to combine it with validation in a single tool. I used DOM parser and specified DOMErrorHandler. Instead of a set of errors with detailed messages like I saw from xmllint for the same xml and xmlschema files, only one message appeared that document has a wrong structure without details. Probably, I did something wrong. But also assume XercesC doesn't contain xmllint functionality right from the box. Does anybody can give me a hint before I spent too much time? Thanks.

• What is the best way to deserialize generics written with a different version of a signed assembly?

  - by Rick Minerich

  In other cases it has been suggested that you simply add a SerializationBinder which removes the version from the assembly type. However, when using generic collections of a type found in a signed assembly, that type is strictly versioned based on its assembly. Here is what I've found works. internal class WeaklyNamedAssemblyBinder : SerializationBinder { public override Type BindToType(string assemblyName, string typeName) { ResolveEventHandler handler = new ResolveEventHandler(CurrentDomain_AssemblyResolve); AppDomain.CurrentDomain.AssemblyResolve += handler; Type returnedType; try { AssemblyName asmName = new AssemblyName(assemblyName); var assembly = Assembly.Load(asmName); returnedType = assembly.GetType(typeName); } catch { returnedType = null; } finally { AppDomain.CurrentDomain.AssemblyResolve -= handler; } return returnedType; } Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args) { string truncatedAssemblyName = args.Name.Split(',')[0]; Assembly assembly = Assembly.Load(truncatedAssemblyName); return assembly; } } However, causing the binding process to change globally seems rather dangerous to me. Strange things could happen if serialization was happening in multiple threads. Perhaps a better solution is to do some regex manipulation of the typeName? What do you think?

• Best Template Engine for ASP.NET MVC

  - by OnesimusUnbound

  I am exploring ASP.NET MVC and I wanted to add jQuery to make the site interactive. I used StringTemplate, ported to .Net, as my template engine to generate html and to send JSON. However, when I view the page, I could not see it. After debugging, I've realized that the $ is used by the StringTemplate to access property, etc and jQuery uses it too to manipulate the DOM. Gee, I've looked on other template engines and most of them uses the dollar sign :(. Any alternative template engine for ASP.Net MVC? I wanted to retain jQuery because MSFT announced that it will used in the Visual Studio (2008?) Thanks in Advance :)

• need a web browser in my desktop application

  - by javadahut

  part of the specification of this desktop application is to have a mini browser built in, so that you can enter URL, and navigate the site as you would on a normal browser. Access to the browser page's DOM is required, should let me programmatically change the rendering view of a page, should be cross-platform, renders javascript JDIC seems outdated and I've heard Mozswing doesn't run on Mac.... Jxbrowser license costs a grand and up. Is Java the wrong platform to be creating such app? Are there any other solutions out there for building an application like this ? Thank you.

• Is there a Post-Build Extensible Installer System

  - by Will Hughes

  We have a product that we need to create an installer for. It has a number of components which can be installed or not as the situation demands. When we ship our installation package, we want to be able to have that include any number of additional components to be installed. For example, Foo Manager Pro contains: Foo Manager Console Foo Manager Database Foo Manager Services That might be shipped as something like: FooManagerInstaller.exe FMPConsole.pkg FMPDatabase.pkg FMPServices.pkg A package might consist of something like: Manifest Files to be deployed Additional scripts to be executed (eg find file foo.config, do some XML Manipulation) If a client wants to add custom skins and a series of plugins as part of the install, they create their own packages: FMPConsoleSkins.pkg ClientWebservices.pkg If that client then ships it to someone else who wants to add more customisation - they can do so in the same way. We can build this from scratch - but wanted to check if this sort of install system already exists. We already have a set of NAnt scripts which do something not too far from this. But they're difficult to maintain, and quite complex. They don't offer any of the 'niceties' that we'd expect from an installer (like tracking deployed files and removing them if the install fails). We've been looking a little bit at NSIS and building MSIs using WiX, but it's not clear that these can offer us the capability for downstream to provide additional packages, without inventing our own installer language.

• selectors-api for data attributes

  - by MJ

  In HTML5, CSS selectors seem to operate well with data-* attributes. For example: <style> div[data-foo='bar'] { background:#eee; } </style> <div data-foo='bar'>colored</div> <div>not colored</div> will properly style the first . But, attempts to select such elements using the selectors-api fail. Examples: var foos = document.querySelectorAll("div[data-foo]='bar'"); or var foos = document.querySelectorAll("div data-foo='bar'"); in Chrome and Safari, this produces a cryptic error: SYNTAX_ERR: DOM Exception 12 Any thoughts on how to use the selectors-api to properly select elements on the basis of data-* attributes?

• Jquery selectors by CSS class in IE is really slow--workarounds?

  - by Sam Lee

  I have a web app where I have several elements with class="classA". I want to select and apply a function to all of them. I am doing the obvious thing, which is $(".classA").each(function () { ... }). This works just fine in Chrome/Safari/Firefox but is really slow in IE. It turns out IE has serious performance issues when selecting things by CSS class in jQuery. I was wondering if anyone has suggestions on good ways to deal with this. I can't use ID selectors because there can be multiple DOM elements I want to select.

• JavaScript data formatting/pretty printer

  - by Dan

  I'm trying to find a way to 'pretty print' a JavaScript data structure in a human-readable form for debugging. I have a rather big and complicated data structure being stored in JS and I need to write some code to manipulate it. In order to work out what I'm doing and where I'm going wrong, what I really need is to be able to see the data structure in its entirety, and update it whenever I make changes through the UI. All of this stuff I can handle myself, apart from finding a nice way to dump a JavaScript data structure to a human-readable string. JSON would do, but it really needs to be nicely formatted and indented. I'd usually use Firebug's excellent DOM dumping stuff for this, but I really need to be able to see the entire structure at once, which doesn't seem to be possible in Firebug. Any suggestions welcome, thanks in advance.

• Should frontend and backend handled by different controllers?

  - by DR

  In my previous learning projects I always used a single controller, but know I wonder if that is good practice or even always possible. In all RESTful Rails tutorials the controllers have a show, an edit and an index view. If an authorized user is logged on, the edit view becomes available and the index view shows additional data manipulation controls, like a delete button or a link to the edit view. Now I have a Rails application which falls exactly into this pattern, but the index view is not reusable: The normal user sees a flashy index page with lots of pictures, complex layout, no Javascript requirement, ... The Admin user index has a completly different minimalistic design, jQuery table and lots of additional data, ... Now I'm not sure how to handle this case. I can think of the following: Single controller, single view: The view is split into two large blocks/partials using an if statement. Single controller, two views: index and index_admin. Two different controllers: BookController and BookAdminController None of this solutions seems perfect, but for now I'm inclined to use the 3rd option. What's the preferred way to do this?

• What's so bad about in-line CSS?

  - by ChessWhiz

  When I see website starter code and examples, the CSS is always in a separate file, named something like "main.css", "default.css", or "Site.css". However, when I'm coding up a page, I'm often tempted to throw the CSS in-line with a DOM element, such as by setting "float: right" on an image. I get the feeling that this is "bad coding", since it's so rarely done in examples. I understand that if the style will be applied to multiple objects, it's wise to follow "Don't Repeat Yourself" (DRY) and assign it to a CSS class to be referenced by each element. However, if I won't be repeating the CSS on another element, why not in-line the CSS as I write the HTML? The question: Is using in-line CSS considered bad, even if it will only be used on that element? If so, why? Example (is this bad?): <img src="myimage.gif" style="float:right" />

• jQuery properties - problem

  - by Cristian Boariu

  Hi, I use this plugin: jQuery.i18n.properties I put this code: /* Do stuff when the DOM is ready */ jQuery(document).ready(loadMessage); /* * Add elements behaviours. */ function loadMessage() { jQuery("#customMessage").html("test"); jQuery.i18n.properties({ name:'up_mail_messages', path:'https://static.unifiedpost.com/apps/myup/customer/upmail/upmail_messages/', mode:'both', language:'en', callback: function() { var messageKey = 'up.mail.test'; //alert(eval(messageKey)); jQuery('#customMessage').html(jQuery.i18n.prop(messageKey)); } }); } I do not understand why, in the customeMessage div it prints out: [up.mail.test] instead of the value of it: up.mail.test=messages loaded from en Can anybody show me where i am wrong? I;ve spent about two hours on it without finding any clue... Many Thanks. Ps: here is the message file: https://static.unifiedpost.com/apps/myup/customer/upmail/upmail_messages/up_mail_messages_en.properties

• Most Lite-Weight XML Parser with XPath and Wide-char Support

  - by Mystagogue

  I want a lite-weight C++ XML parser/DOM that: Can take UTF-8 as input, and parse into UTF-16. Maybe it does this directly (ideal!), or perhaps it provides a hook for the conversion (such as taking a custom stream object that does the conversion before parsing). Offers some XPath support. I've been looking at RapidXML, the Kranf xmlParser, and pugiXML. The first two of those might permit requirement #1 by way of a hook. The third, pugiXML, supports the #2 requirement. But none of those three fulfill both requirements. What is the smallest (free) library that can handle both requirements?

• What are some of best Javascript memory detecting tools?

  - by Philip Fourie

  Our team is faced with slow but serious Javascript memory leak. We have read up on the normal causes for memory leaks in Javascript (eg. closures and circular references). We tried to avoid those pitfalls in the code but it likely we still have unknown mistakes left in our code. I started my search for available tools but would like input from people with actual experience with these tools. Some of the tools I found so far (but have no idea how good and useful they would be for our problem): Sieve Drip JavaScript Memory Leak Detector Our search is not limited to free tools, it will be a bonus, but more importantly something that will get the job done. We do the following in our Javascript code: AJAX calls to a .NET WCF back-end that send back JSON data Manipulate the DOM Keep a fairly sized object model in the Javascript to store current state

• Convert pre-IEEE-574 C++ floating-point numbers to/from C#

  - by Richard Kucia

  Before .Net, before math coprocessors, before IEEE-574, Microsoft defined a bit pattern for floating-point numbers. Old versions of the C++ compiler happily used that definition. I am writing a C# app that needs to read/write such floating-point numbers in a file. How can I do the conversions between the 2 bit formats? I need conversion methods in both directions. This app is going to run in a PocketPC/WinCE environment. Changing the structure of the file is out-of-scope for this project. Is there a C++ compiler option that instructs it to use the old FP format? That would be ideal. I could then exchange data between the C# code and C++ code by using a null-terminated text string, and the C++ methods would be simple wrappers around sprintf and atof functions. At the very least, I'm hoping someone can reply with the bit definitions for the old FP format, so I can put together a low-level bit manipulation algorithm if necessary. Thanks.

• Escaping colons in hibernate createSQLQuery

  - by Stratosgear

  I am confused on how I can create an SQL statement containing colons. I am trying to create a view and I am using (notice the double colons): create view MyView as ( SELECT tableA.colA as colA, tableB.colB as colB, round(tableB.colD / 1024)::numeric, 2) as calcValue, FROM tableA, tableB WHERE tableA.colC = 'someValue' ); This is a postgres query and I am forced to use the double colons (::) in order to correctly run the statement. I then pass the above statement through: s.createSQLQuery(myQuery).executeUpdate(); and I get a: Exception in thread "main" org.hibernate.exception.DataException: \ could not execute native bulk manipulation query at org.hibernate.exception.SQLStateConverter.convert(\ SQLStateConverter.java:102) ... more stacktrace... with an output of my above statement changed as (notice the question mark): create view MyView as ( SELECT tableA.colA as colA, tableB.colB as colB, round(tableB.colD / 1024)?, 2) as calcValue, FROM tableA, tableB WHERE tableA.colC = 'someValue' ); Obviously, hibernate confuses my colons with named parameters. Is there a way to escape the colons (a google suggestion that mentions that a single colon is escaped as a double colon does NOT work) or another way of running this statement? Thanks.

• jQuery selector help - Can I generate a selector from clicking on an element?

  - by Kettenbach

  Hi All, I have jQuery, FireFox, Firebug, IE, and IE developer toolbar. When I am examing a page with either FireBug or IE Dev toolbar, I am able to click on an element and it shows me in the dom where the element is etc... Is there anyway to transform that selection into a valid jQuery selector? I know I can use ID, classes, and element relative to other elements etc... but what about when I am looking at some random table cell that doesn't have a class or id etc.. Can I generate a selector on the fly like that? I thought for sure there was. Any thoughts or ideas are always appreciated Thanks, ~ck in San Diego

• Define variable in variable/parameter and use in javascript?

  - by Ross

  I want to defined a variable/parameter in CSS and access it by javascript. What is the best way of doing this? One option I thought of would be to place a cutsom attribute on the body element, then access that attribute via jQuery. A little more info: I'm defining colour sets in CSS. I've created a function with RaphaelJS to draw a gradient background on the page. I want this function to use a highlight colour (which is not used elsewhere on the DOM) which will be defined in the CSS along with the other colour elements. Thanks

• Unique element ID to reference later

  - by Hanpan

  I'm trying to figure out a method of storing a unique reference to each tag on a particular page. I won't have any ability to edit the page content and I'll the generated UID to stay the same on every page refresh. Since browsers don't generate any kind of UID for elements, I was thinking that the only method to do this would be to execute a script which walks the DOM and creates a UID for each it comes across. I don't know how accurate this will be, especially considering I'll need to ensure it creates the same UID for the tag each time the script crawls the page. Can anyone think of any other, more accurate ways of mapping a page? Many thanks.

• button in XSL for AJAX usage

  - by phingko

  Hi guys, I wonder if its is possible to do AJAX when I put a button inside the xsl file; <input type = "button" id="laptop" value = "Add to Cart" onclick="sendCartRequest('Add');" /> That's what I do in my xsl file then in my js file I pass the id to the DOM and try to alert it make sure it is passed. And the alert appear to be empty. Is it a mistake to put the button in the xsl? or that's something else that cause it's empty? May be my DOMpath? Please point me a right direction. Thanks in advanced.
