  • 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.

  • Web Page Opinions and Suggestions

    - by MrEnder
    Been working my * off on this for a few days trying to keep updating it to make it most efficient with everything I learn... I'm quite proud of it so far considering I'm not actually the best coder lol most JS and PHP confuses the crap outa me unless I do it from scratch. So anyways here is the link. Tell me what you think. Suggestions would be amazing. I'd love to know what I screwed up as long as you explain in detail as to why and how to fix it. I really hate when people hand me a huge snippet and expect me to understand it -_- Thanks Shelby LINK http://opentech.durhamcollege.ca/~in...rittains/labs/

  • Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • When should I observe javascript events on window vs. document vs. document.body?

    - by brahn
    I'm using prototype.js for my web app, and I have everything running on chrome, safari, and firefox. I am now working on IE8 compatibility. As I've been debugging in IE, I've noticed that there are javascript events for which I have previously set an observer on the window, e.g. Event.observe(window, eventType, function () {...}); (where eventType might be "dom:loaded", "keypress", etc.) and it works just fine in Chrome/Safari/Firefox. However, in IE the observer never fires. In at least some cases I could get this to work on IE by instead placing the observer on something other than window, e.g. document (in the case of "dom:loaded") or document.body (in the case of "keypress"). However, this is all trial-and-error. Is there some more systematic way to determine where to place these observers such that the results will be cross-browser compatible? Thanks!

  • Which one should I choose AMQP or XMPP for real-time browser-based game?

    - by Devyn
    Hi, I'm choosing between AMQP (RabbitMQ) vs XMPP (eJabberd) for my browser-based flash-free javascript powered real-time turn-based game. I don't know much about AMQP and XMPP protocol. I would like to use PHP for user-authorization and some data store-retrieve with MySQL. As far as I found out, RabbitMQ has PHP clients but eJabberd not. What I understood is javascript client calls PHP script and manipulate necessary processing and then pass to AMQP or XMPP server to pass the data to opponent player. There is a good book 'Pro XMPP Programming with JS and jQuery' from Wrox but there is no example with PHP. So following are my questions. 1) Which protocol is suit for my game? 2) Shall I choose RabbitMQ just for it's PHP client support?

  • How do you use vim's quickfix feature?

    - by hora
    I'm a pretty new Vim user and I've found that its learning curve is quite steep (at least for me). I just installed this vim script for JavaScriptLint error checking, which shows errors in vim's quickfix window once I save a buffer. However, I don't know what to do next.. How do I 'scroll' through all the errors? How do I close the quickfix 'window'? How do I get it to check for errors after I've made changes to my code? I've looked at the vim quickfix docs but the amount of commands are overwhelming and I can't seem to find what I want. Any help would be appreciated. A side question: is there any way to have javascriptlint check for js errors for code residing in a .html file? Thanks!

  • Using Javascript in Google Web Optimizer Page Sections

    - by Chris S
    Is it possible to use Javascript in the content of a page section variation? I want different variations to make different Javascript function calls, so I have variation content like: Variation 1 <script type="text/javascript">my_func('abc');</script> Variation 2 <script type="text/javascript">my_func('def');</script> However, when I preview my page, I can't verify that my_func(content){ alert(content); } is actually being run. Does GWO not support JS content, or am I missing something?

  • Django: tinyMCE and cross site javascript

    - by pistacchio
    Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

  • In an ASP.NET Web Site Project, what is the best option to manage modular widgets

    - by Juan Sagasti
    We are creating a modular Web Site Project and all the UI is based on simple html pages with javascript widgets. These widgets obtain the data from a WCF class located in the app_code folder. Each widget has 3 files [ js, css , cs] and an image directory: , and we want all these files to be located under the same directory, say: /widgets/mywidget/ The problem is that the .cs file needs to be in the app_code folder to be compiled dynamically and that would break our widget modularity forcing the installator to distribute the widget code in two places. One of the options is use compiled assemblies instead of .cs files and use Assembly.Load() or smthg similar to load them when needed. What other options do you see?

  • Eclipse Basic Web Development?

    - by Sean Ochoa
    I want to start doing web development with Eclipse. Not Java, tomcat, axis2, or anything else anymore complicated than basic XHTML / JS / CSS development, at this time. Problem 1: I realize that it can edit those files, but its trying to manage my HTML docs as part of "my workspace", and all I want it to do is manage the files as part of my local www server HTdocs directory. Problem 2: I would like to edit WYSIWYG-style, if possible. I tried installing a plug-in for that, but I wasn't able to get w4 toolkit to function properly. This would really help me to speed up development, I think. Follow-up: I've installed WTP and its dependencies (except for the tests portion, which had install problems due to dependencies that were seemingly irreconcilable).

  • Servlet receives OPTIONS instead of GET requests from jQuery?

    - by Urs
    All I want to achieve is to implement a servlet providing a json feed for my fullcalendar application. When I inspect http://arshaw.com/js/fullcalendar/examples/json.html with Bugzilla, I see that GET-requests are sent to receive the json feed. However, when I use this example within my scenario, fullcalendar seems to send OPTIONS-requests. The only difference is that I replaced "events: "json-events.php" with "http://localhost:8080/CalendarServletTest/HelloWorldServlet" (the url of my servlet). What do I miss? Or is this really a bug?

  • Reliable way to get the "ancestor" of an object with a specific classname, using jQuery

    - by Matt Dawdy
    I've got a javascript function that gets called on change event of a select form element. So, the "this" variable in js refers to the select element. This select element is in a td tag, in a tr tag. The tr tag has a classname of "FilterDetailsRow". Now, I've tested, and if I use this syntax: var filterRow = $(this).parent().parent(); it gets me what I want. However, is there a better way to tell jQuery, "starting with "this" can you please go up my tree of parents until you find one with a classname of "FilterDetailsRow"? Here's what I came up with, but I want to make sure I"m not reinventing the wheel. function GetFilterDetailsRowOfObject(o) { if (o) { if (o.parent()[0].className.indexOf("FilterDetailsRow") != -1) return o; else return GetFilterDetailsRowOfObject(o.parent()); } else { return null; } } Thanks for any advice.

  • Uploadify uploadSettings with scripData does not work

    - by kubilayeksioglu
    Hi everyone, I am sending a file to my Java Servlet via jQuery Uploadify, there are no problems while sending the actual file. But when I try to send some scriptData with file along, to process on Servlet it just does not send anything. Here is the JS code: $("button").click(function(){ $("#uploadify").uploadifySettings('scriptData', {'length':'0.2'}); $('#uploadify').uploadifyUpload(); }); $('#uploadify').uploadify({ 'uploader': 'assets/uploadify/uploadify.swf', 'script': 'upload', 'folder': '/uploads' }); And here is the Servlet code on the server side: out.println(res.getParameter("length")); Only output I get is null, while expecting "0.2". I just cannot get what's wrong and any kind of help will be appreciated. Thanks in advance.

  • Geolocation under firefox 3.6 requires Proxy Authentication?

    - by prem
    I am trying to share my location on geolocation enabled pages from firefox 3.6, but doesn't seem to get any kind of success or failures. When I wrote my custom js containing navigator.geolocation.getCurrentPosition(func1,func2), the success callback isn't called at all. When I tamper the http requests on firefox, the request to https://www.google.com/loc/json returns with status: 407 [Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )]... Yes, my network is behind a proxy server. But the same works with Chrome. I didn't try other browsers yet.

  • How do you make javascript code execute *in order*

    - by Ed
    Okay, so I appreciate that Javascript is not C# or PHP, but I keep coming back to an issue in Javascript - not with JS itself but my use of it. I have a function: function updateStatuses(){ showLoader() //show the 'loader.gif' in the UI updateStatus('cron1'); //performs an ajax request to get the status of something updateStatus('cron2'); updateStatus('cron3'); updateStatus('cronEmail'); updateStatus('cronHourly'); updateStatus('cronDaily'); hideLoader(); //hide the 'loader.gif' in the UI } Thing is, owing to Javascript's burning desire to jump ahead in the code, the loader never appears because the 'hideLoader' function runs straight after. How can I fix this? Or in other words, how can I make a javascript function execute in the order I write it on the page...

  • Web Application Translation, methods and tools

    - by CiscoIPPhone
    I've developed a web application. It needs to be translated to languages other than English in the future, and ideally the translators shouldn't need to know HTML/JS/C++ to provide the translation. The server side of the web application is written in C++ and the majority of the localised text is in the HTML files. My question is: What approaches are there to translating web applications? - Are there any existing tools that would enable a translator who doesn't understand HTML to translate a site? Should I write an application that extracts the localised text from a html file and can re-substitute translated text? Do you just provide the html file to your translators to be localised? I'm aware the question isn't strictly programming related but the solution may involve programming and it may require some software engineering.

  • Mac dashboard widgets not loading external images

    - by andrhamm
    I set out to make a quick Mac OS X dashboard widget. I read the documentation and was pleased to find out they use simple HTML, JS, and CSS. I created my widget and it works when I open the .html file in Firefox, but it does not work when I install the widget to the dashboard. The widget is simple: it displays the most recent image from a weather web cam stream. The image URLs look like this: http://webcam.com/stream.jpg?1274213999617. The timestamp is appended to the URL and the server automatically responds with the latest image for that time. I did not write the server script. The widget appears to be loading correctly, but the web cam image will not load. Notice the blue question mark in the upper left. The image should appear over the square background image. Is there any special procedure for loading external images into a widget?

  • Add client-side events to ASP.Net custom control at runtime

    - by nw
    I'm building an ASP.net custom control that implements IScriptControl. I would like other users of my control to be able to assign client-side event handlers to the control. Unfortunately the JS generated by IScriptControl is always injected at the very bottom of the rendered page (see below), so any attempt to assign an event handler in the ASPX page fails because the code executes too early. ... <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(MyNamespace.MyControl, {}, null, null, $get("my_control_id")); }); //]]> </script> </form> What's the right way to assign an event handler to the instantiated control upon page load?
