• Zend Framework - tinyMCE - plugin folders are mistaken to be controllers? Help

  - by Ali

  Hi guys I'm trying to integrate the tinymce plugin however I'm running into problems such that almost every feature which requires a plugin to be rendered i.e the add url popup or add image pop up - it opens an empty pop up window. Even if I try to open it inline I get the same blank popup window.. I noticed that whenever I click on lets say url button in tinymCE it opens with reference to my localhost and because of that I'm assuming my application is mistaking the containing javascript folder to be some controller or action. How can I fix this please - I've set up mod rewrite to allow clean urls as well as ignore the javascript folder but this is a different issue altogether :( what should I be looking at here.. I can't notice any error sin firebug..

• Rails ActiveRecord BigNum to JSON

  - by Jon Hoffman

  Hi, I am serializing an ActiveRecord model in rails 2.3.2 to_json and have noticed that BigNum values are serialized to JSON without quotes, however, javascript uses 64 bits to represent large numbers and only ~52(?) of those bits are available for the integer part, the rest are for the exponent. So my 17 digit numbers become rounded off, grrr. Try the following in the Firebug console: console.log(123456789012345678) So, I'm thinking that the json encoder should be smart enough to quote numbers that are too big for the javascript engines to handle. How do I fix up rails to do that? Or, is there a way to override the encoding for a single property on the model (I don't want to_s elsewhere)? Thanks.

• How to inform users that webapplication does not support IE6

  - by Paul Szulc

  I have web application and I do not really care about IE6 users. However I would like to have some kind of feautre that would informe users that they are using IE6 and that their browser is not supported. I was thinking about two possible solutions: pop-out window (probably Javascript) with text informing the user on every page he enters some special page with information, that user would be redirected to whenever he tries to access my application Both solutions will be sufficient, however I would prefer the second one. Probably some magic javascript needs to be involved, can anyone could please provide a solution to this?

• jQuery AJAX not redirecting?

  - by MidnightLightning

  I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?

• RegAsm for Class Library Used in VB6 Application

  - by michael.lukatchik

  To be short and to the point, I've built a C# class library that is both COM-Visible and Registered for COM Interop. I've compiled the library, which resulted in the generation of .dll and .tlb files. I have another machine that's running a VB6 application. So, I copied the .dll and .tlb files over to C:/Windows/system32 folder on the machine. I then registered those files using the following: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\Windows\system32\TestClass.dll /tlb:TestClass.tlb After the files were registered successfully, I added a project reference to the Test.tlb file from inside my VB6 app, then I tried to invoke a method in my new referenced class like so: Dim myObject As TestNamespace.TestClass Set myObject = New TestNamespace.TestClass MsgBox (myObject.TestMethod()) It doesn't work, and I receive a -2147024894 Automation Error. I've read that I shouldn't install the dll into a private folder like system32. I should either be registering in the GAC or I should be registering in another location using the "/codebase" option: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\TestClass.dll /tlb:TestClass.tlb /codebase Is there any reason I shouldn't be using system32? Past devs that have worked on this project have placed assembly files used by this VB6 project into system32 and there haven't seemed to be any issues. When I register my dll in the system32 location, I get the Automation Error. When I register my dll in another location (i.e. C:/), the method call into my class library from VB6 works as expected. What gives? I should mention that we will NOT be using the GAC to register any DLL's. That's just the way it is. Any help is appreciated. Mike

• Setting a session variable in Global.asax causes AJAX errors

  - by Fly_Trap

  I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour. If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below. E.g. I have file called JScript.js containing the code: function myAlert() { alert("Hi World"); } And in my Default.aspx file I reference the js with the code: <script src="JScript.js" type="text/javascript"></script> And in the body onload event I call the myAlert() function: <body onload="myAlert()"> And finally in the Global.asax file: Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs) HttpContext.Current.Session("myVar") = "MyValue" End Sub If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads. Why is this?

• AJAX - Get response URL after redirect

  - by Stian

  Hello, I was wondering if there is a way to get the URL of the returned resource after a AJAX call in JavaScript? I want to use this with a form, which is in "mysite.com/users/add.html". This is a Spring MVC controller. If the validation of the form fails the controller will return the "users/add" view, but if the validation is OK it will do a redirect to "mysite.com/users/index.html", using return new ModelAndView(new RedirectView("/users/index.html")); Is there a way in JavaScript to find the URL of the returned page? Thanks, Stian

• Jquery broken by GetResponse (email marketing) web form script

  - by Jacob

  I'm working on a site that relies on quite a bit of javascript. The problem is, I'm not a javascript guru in the least. Yes, bit off more than I can chew, here. I'm using jquery for a spy effect, and use GetResponse for email signups. If I implement my GetResponse script, it breaks the area later in the page which depends on the jquery script. Pull the GetResponse script and it works just fine. Problem is, I need them both. ;) The trick, I suppose, is that the GetResponse script is actually another Jquery script, so it's getting called twice... Any help? The site is http://djubi.com/testserver Check out (urlabove)/nogetresponsescript.php to see it work without the GetResponse script. You should be able to see all the source just fine. Thanks everyone. jf

• jQuery - change a list of elements to an associative array

  - by Brian M. Hunt

  Given an associative array (of the sort returned by jQuery.serializeArray()) like this: [ { 'name': 'abc', 'value': 'aaa', '__proto__': [Object] }, { 'name': 'def', 'value': 'bbb', '__proto__': [Object] }, { 'name': 'abc', 'value': 'ccc', '__proto__': [Object] } ] How can one convert this, using either jQuery or just javascript, to an associative array of name: [values] like this: { 'abc': ['aaa', 'ccc'], 'def': ['bbb'] } This seems to essentially be the inverse of this question: Build associative array based on values of another associative array... but in Javascript (not PHP). I wasn't able to find this question on Stackoverflow, though I thought it would have been asked. Thank you for reading. Brian

• SetTimeout() and ClearTimeout() to stop freezing of IE8 and dialog aobut scripts overruning

  - by igl00

  I have some 3rd party software where i can open nsites and run javascript. Because some sites make me stack overflow i ussed the trick wih Registry to modify Styles WRAD to FFFFFF. Still some sites may do stack overflow due to DOM. I thought on start of running each site i would do javascript: setTimeout("window.status='one';",10000); then on then end i would like to clear it - my question is how to if this doesnt have any actual id? Will the usual clearTimeout() without anything inside do it fine?

• What is the best practice for writing bookmarklets

  - by Ritesh M Nayak

  I am writing some bookmarklets for a project that I am currently working on and I was wondering what the best practice for writing a bookmarklet was. I did some looking around and this is what I came up with javascript:void((function() { var%20e=document.createElement('script'); e.setAttribute('type','text/javascript'); e.setAttribute('src','http://someserver.com/bookmarkletcode.js'); document.body.appendChild(e) })()) I felt this is nice because the code can always be changed (since its requested every time) and still it acts like a bookmarklet. Are there are any problems to this approach ? Browser incompatibility etc? What is the best practice for this?

• GWT's JSONParser producing incorrect values for numbers.

  - by WesleyJohnson

  I'm work with GWT and parsing a JSON result from an ASP.NET webservice method that returns a DataTable. I can parse the result into a JSONvalue/JSONObject just fine. The issue I'm having is that one my columns in a DECIMAL(20, 0) and the values that are getting parsed into JSON aren't exact. To demonstrate w/o the need for a WS call, in GWT I threw this together: String jsonString = "{value:4768428229311981600}"; JSONObject jsonObject = JSONParser.parse( jsonString ).isObject(); Window.alert( jsonObject.toString() ); This in turn alerts: {"value":4768428229311982000} I'm under the understanding that GWT's JSONParser is just using eval() to do the parsing, so is this some sort of number/precision issue with JavaScript that I've never been aware of. I'll admit I don't work with numbers that much in JavaScript and I might be able to work around this by changing the .NET WebService to return this column as string, but I'd really rather not do that. Thanks for any help.

• Why does IE8 change flash callback function into object?

  - by Christian Hollbaum

  Hi Guys I have put 2 swf's (using swfobject 2) on the same website; One for playing a movie, and one for controlling the movie (I want to position them seperately, so they can't be in the same swf). I'm doing the communication between the two using javascript with jQuery, and externalcallback functions in both swf's. Everything is running smoothly on all browsers, but IE8. In IE8 I can only call the pause callback function in the control swf once. When it has been called it will not run properly the next time. After trying to debug what is happening live, using javascript's "type of" I have found that IE8 changes the callback function on the flash object from a function into an object when it has been triggered. Can anyone explain why this is happening? .. and maybe suggest how to avoid this? .. or change the object back to a function?

• Will ExtJS die?

  - by Stefan Kendall

  I look at ExtJS, and it appears to provide many of the RIA features that more bulky suites such as Flex provide, without the flash requirement. However, as Open-source initiatiatives such as jQuery-UI continue, will ExtJS simply die at some point? Furthermore, since flash penetration only continues to increase, why put stock in a javascript library? That said, JavaScript libraries such as jQuery have made gigantic leaps in providing easy-to-use APIs with great functionality, so maybe there's some merit in that. Thoughts? Opinions? ExtJS has a price tag, so I have to ask this question.

• What to do when GMap Satellite imagery is unavailable

  - by robstenson

  Hello-- is it possible to programmatically detect with the google maps api (javascript, v2) when satellite imagery is unavailable at a certain zoom level? I am creating some maps automatically and setting them to a certain zoom level, but in a few cases there is no satellite imagery available at that level, in which case I'd like to automatically back up a zoom level. Does the api expose some way of determining this lack of imagery? So far the only thing I can think of is trying to find out, with javascript, whether or not the image requests that the api makes are failing, and then reacting based on those failed image requests, but I can't really get it to work... and it seems a little inelegant. Thanks for your help!

• Fancy Box doesnt work please help

  - by JL

  I recently came across fancy box located here, I've followed every step in the instructions perfectly, but it doesn't work, anyone know what might be the problem? Here is a sample of my page source: Included the links to scripts as required, and CSS: <script src="jquery.fancybox-1.2.1/jquery.fancybox/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="jquery.fancybox-1.2.1/jquery.fancybox/jquery.fancybox-1.2.1.js" type="text/javascript"></script> <link href="jquery.fancybox-1.2.1/jquery.fancybox/jquery.fancybox.css" rel="stylesheet" type="text/css" /> <link href="css/main.css" rel="stylesheet" type="text/css" /> Then this should simply work: <a id="single_image" href="images/279641.jpg"><img src="images/279641.jpg" /></a> But it doesn't seem to do anything except open the image in a new window. Any suggestions, and thanks in advance.

The problem is i can't display the form again to make the user unscrambled the second, third ..etc words..

• Dynamically pixelate an html image element

  - by Chris Armstrong

  I'm to take an image on a webpage, and then use javascript (or whatever would be best suited) to dynamically 'pixelate' it (e.g. into 20px squares). Then, as the user scrolls down the page, I need the image to gradually increase in resolution, till it is no longer pixelated. Any ideas how I could go about doing this? I realise I could use php to resize an image and several times and just switch out the image, but that would require loading several extra images. Also, I know I could probably do the effect with flash & pixelbender, but I want to achieve it within the limitations of HTML5, CSS & Javascript if possible. Appreciate any thoughts!

• Is it possible to implement any kind of file upload recovery / resumption in a browser?

  - by Pete

  The project is a servlet to which people can upload files via, at present, HTTP POST. This is accompanied by Web page(s) providing a front-end to trigger the upload. We have more or less complete control over the servlet, and the Web pages, but don't want to impose any restrictions on the client beyond being a reasonably modern browser with Javascript. No Java applets etc. Files may potentially be large, and a possible use case is mobile devices on less reliable networks. Some people on the project are demanding the ability to resume an upload if the network connection goes down. I don't think this is possible with plain HTTP and Javascript in a browser, but I'd love to be proved wrong. Any suggestions?

• Why aren't double quotes and backslashes allowed in strings in the JSON standard?

  - by Dan Herbert

  If I run this in a JavaScript console in Chrome or Firebug, it works fine. JSON.parse('"\u0027"') // Escaped single-quote But if I run either of these 2 lines in a Javascript console, it throws an error. JSON.parse('"\u0022"') // Escaped double-quote JSON.parse('"\u005C"') // Escaped backslash RFC 4627 section 2.5 seems to imply that \ and " are allowed characters as long as they're properly escaped. The 2 browsers I've tried this in don't seem to allow it, however. Is there something I'm doing wrong here or are they really not allowed in strings? I've also tried using \" and \\ in place of \u0022 and \u005C respectively. I feel like I'm just doing something very wrong, because I find it hard to believe that JSON would not allow these characters in strings, especially since the specification doesn't seem to mention anything that I could find saying they're not allowed.
