  • 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

  • organise javascript code based on page

    - by David
    Hi I am relatively new to javascript development. At the moment I have a single javascript file with lots of little misc bits of code that get called in different part of the website. For example I have an event handler for some google maps stuff that is only called on 1 single page, I have some validation stuff for my contact page etc etc. My question, is how best to organise this code - given that each page only requires very little code but its different and specific per page? Oh, I am using jquery if that makes a difference.

  • How will Facebook Authenticate let me ID a user?

    - by Donny P
    I have a website where I need to have data that is ID'd by user. For example, they enter their favorite food: userid favorite food ------ ------------- 1 french fries 2 tacos 3 fish sticks 4 chipotle When I use Facebook Authentication, what identifier will I use for the userid? I'm assuming it's not name, since this would create duplicates. Is it just the person's Facebook ID? Also is the correct API to use for 3rd party websites 'Facebook Connect' or 'Facebook Authorization' or something else?

  • Disable JavaScript on window.open

    - by sonofdelphi
    I have a set of (X)HTML files that I need to open with window.open() from an application homepage. I am able to open these files and read the data within them. function openFiles() { var files = document.querySelectorAll('td a'); //The list of files to scan is stored as links in an HTML table for(var i = 0; i<files.length; i++){ //Open each file in a browser window win = window.open(files[i].href); //Can I prevent the JavaScript in these files from executing? } } But the problem is that the scripts within the HTML files also get executed when opened like this. This is rather time-consuming and unnecessary; also, the scripts within those files may have side-effects. Is there a way to prevent JavaScript from executing on load?

  • How do I add and remove an event listener using a function with parameters?

    - by Bungle
    Sorry if this is a common question, but I couldn't find any answers that seemed pertinent through searching. If I attach an event listener like this: window.addEventListener('scroll', function() { check_pos(box); }, false); it doesn't seem to work to try to remove it later, like this: window.removeEventListener('scroll', function() { check_pos(box); }, false); I assume this is because the addEventListener and removeEventListener methods want a reference to the same function, while I've provided them with anonymous functions, which, while identical in code, are not literally the same. How can I change my code to get the call to removeEventListener to work? The "box" argument refers to the name of an <iframe> that I'm tracking on the screen; that is, I want to be able to subscribe to the scroll event once for each <iframe> that I have (the quantity varies), and once the check_pos() function measures a certain position, it will call another function and also remove the event listener to free up system resources. My hunch is that the solution will involve a closure and/or naming the anonymous function, but I'm not sure exactly what that looks like, and would appreciate a concrete example. Hope that makes sense. Thanks for any help!

  • android mobile development performance vs extensibility

    - by mixm
    im developing a game in android, and i've been thinking about subdividing many of the elements of the game (e.g. game objects) into separate classes and sub-classes. but i know that method calls to these objects will cause some overhead. would it be better to improve performance or to improve extensibility?

  • Is there way to extend jQuery to handle a custom enter key event?

    - by Ken
    I write the following code all the time to handle when the enter key pressed: $("#selectorid").keypress(function (e) { if (e.keyCode == 13) { var targetType = e.originalTarget ? e.originalTarget.type.toLowerCase() : e.srcElement.tagName.toLowerCase(); if (targetType != "textarea") { e.preventDefault(); e.stopPropagation(); // code to handler enter key pressed } } }); Is there a way to extend jQuery so that I could just write: $("#selectorid").enterKeyPress(fn);

  • Make a steady automata in javascript

    - by RobertWHurst
    I'm working on a javascript game and I've got an automata system controlling game time and sprite animation as well as giving a hand to the path finding system for timing and such. My problem is on slow browsers the javascript loop I'm using for counting the time is not very accurate. It tends to jump around a lot. I there a way to force the loop to run consistantly at 30 fps? The automata can drop frames if it needs to catch up so if the solution requires droping frames thats ok.

  • Most hazardous performance bottleneck misconceptions

    - by David Murdoch
    The guys who wrote Bespin (cloud-based canvas-based code editor [and more]) recently spoke about how they re-factored and optimize a portion of the Bespin code because of a misconception that JavaScript was slow. It turned out that when all was said and done, their optimization produced no significant improvements. I'm sure many of us go out of our way to write "optimized" code based on misconceptions similar to that of the Bespin team. What are some common performance bottleneck misconceptions developers commonly subscribe to?

  • How to retrieve a style's value in javascript?

    - by stan
    I am looking for a way to retrieve the style from an element that has a style set upon it by the style tag. <style> #box {width: 100px;} </style> In the body <div id="box"></div> I'm looking for straight javascript without the use of libraries. I tried the following, but keep receiving blanks: alert (document.getElementById("box").style.width); alert (document.getElementById("box").style.getPropertyValue("width")); I noticed that I'm only able to use the above if I have set the style using javascript, but unable to with the style tags.

  • Change color of a table cell using javascript using dropdown menu

    - by Mike Burzycki
    I'd like to use some javascript code to change the background color of a single cell within a table. I have some code below which allows me to change the page background color. This is similar in concept to what I would like to do, but I would really like to be able to change just one cell...not the whole page. I have thought about making the rest of the cell borders and background colors white, leaving the cell I want to manipulate transparent, but I think this probably a brute force method that will cause me trouble down the road. Does anyone have any advice to do this with javascript? The page background color changing code is here: <form name="bgcolorForm">Try it now: <select onChange="if(this.selectedIndex!=0) document.bgColor=this.options[this.selectedIndex].value"> <option value="choose">set background color <option value="FFFFCC">light yellow <option value="CCFFFF">light blue <option value="CCFFCC">light green <option value="CCCCCC">gray <option value="FFFFFF">white </select></form> Thanks for the help, Mike

  • Performance of a proposed JEE architecture

    - by kineas
    I have concerns about the performance of the following architecture: j2ee application in an appserver, ejb session bean and DAOs remote (rich) client, a swing app. A classic, form-based client only one stateless ejb, the ejb is accessed via web services, not rmi, through a homegrown framework each web service request will get authenticated against an LDAP no state stored on the server, only client-side sessions I guess working on the rich GUI will involve a remote call in every 2-10 seconds, or more, per user. What do you think?

  • Implementing OFX specification with javascript

    - by John Langston
    Hey all, I am working on a personal project and need to retrieve financial data. After looking around how this is normally done it seems you can pay lots of money and license a service like Yodlee to get this data for you or you can implement a OFX client like wesabe has to communicate with financial institutions. Seeing as I don't have lots of money and wouldn't mind the challenge I decided to try to implement the ofx spec (unless one of you can suggest a cheap/free alternative!). I looked around for some ofx libraries other people have already written for use but didn't find anything that looked too great. I was wondering if anyone knew if it would be a bad idea to attempt this in Javascript (using XMLSocket from actionscript to handle the actual socket communication). If there is some really bad reason why I shouldn't do this please bring it up. If there is I'll just do it in Java but I think it would be neat to have it completely in javascript so it runs client-side. Anyways I was hoping for some helpful input, thanks.

  • My javascript to jQuery translation has a bug

    - by donpal
    My guess is that this javascript just finds the div called divid and then uses it with the sendit function. var somevalue = 19; if (navigator.appName.indexOf("Microsoft") != -1) { thediv = window["divid"]; } else { thediv = document["divid"]; } thediv.sendit(somevalue); I would imagine in jQuery it would look something as simple as this: var somevalue = 19; $('divid').sendit(somevalue); But it's not working!! What could I be missing? I should say that it's in the middle of other javascript code, could that be a problem?

  • Page zoom slows down page rendering

    - by Alex
    I'm building a map viewer much like Google maps and i've run into an interesting performance problem when a page is zoomed (i.e ctrl + OR ctrl -). It seems to affect all major browsers but Firefox has the worst problems as far as I can tell. The problem is that when the page is zoomed panning by dragging the mouse seems really sluggish. This can even be seen on Google maps. Pan the map left and right and note how smooth it is. Now press ctrl+ (3 or 4 times). Now pan the map left and right in the same way. Notice the difference? Does anyone know how I can minimize this problem?

  • assigning variables to DOM event listeners when iterating

    - by ptrn
    I'm thinking there's something basic stuff I'm missing here; for (var i=1; i<=5; i++) { var o = $('#asd'+i); o.mouseover(function() { console.info(i); }); } When hovering over the five different elements, I always get out the last value from iteration; the value 5. What I want is different values depending of which element I'm hovering, all from 1 to 5. What am I doing wrong here?

  • Testing site performance with multiple browsers and versions

    - by jasongullickson
    We're trying to document the performance difference of our site using different browsers. We use LoadRunner for load testing but I don't see a way to specify the "browser engine" it uses to run it's tests (perhaps it's using it's own?). In any event I'm not sure that LoadRunner is the right tool for this job but we own it so if we can use it, great. If not, is there another tool out there that I can use to record a script and run it automatically against a site using several different browsers?
