I'm working on drawing an SVG grid using Javascript. I've managed to get the axis drawn, as well as my quadrant labels. However I've run into an issue adding my dynamic points. I'm trying to draw the points in the onload event of the SVG element. When using Firebug I have been able to confirm that the circle elements representing my poi...
For my small wiki application, I mostly need to have the textarea used to edit the contents to use soft (or virtual) wrapping. However, in some cases, not wrapping the content would be preferable. I thought I would do this by simply having a button to turn off wrapping. Here is the simplified code: <form name="wikiedit" action="[[scri...
Can I convert a string representing a boolean value (e.g., 'true', 'false') into a intrinsic type in JavaScript? I have a hidden form in HTML that is updated based upon a user's selection within a list. This form contains some fields which represent boolean values and are dynamically populated with an intrinsic boolean value. However, o...
I want to be able to get a list of all differences between two JavaScript object graphs, with the property names and values where the deltas occur. For what it is worth, these objects are usually retrieved from the server as JSON and typically are no more than a handful of layers deep (i.e. it may be an array of objects that themselves...

I can't seem to get Javascript debugging working for my ASP.NET MVC application even though I can for a traditional ASP.NET WebForm app. I have followed the steps for unchecking the 'Disable Script Debugging' boxes for both IE and other. when I add a simple function to display an alert in both the site.master and any content view the b...
My code works great in IE8, Firefox and Safari. But it doesn't work properly in Opera. What happens is that the DIV is hidden but the space occupied by the DIV remains to appear in my web-page. <div style=" z-index:-1;height :380; width:760; position:relative; text-align:center" id="new-add"> <object id="banner-flash" classid="clsi...

I'm using event delegation to listen for events lower in the DOM, but it's not working for an onchange event on a select box. Does the onchange event propagate or bubble up the DOM? Googling has failed in finding a conclusive answer. ...
I've been working on a project called Axial that converts MSIL (compiled C# or VB.NET) to JavaScript. There are a few samples of working code, but some common situations don't work properly. (The current release doesn't work in production mode and the SVN code doesn't work in debug mode but is much cleaner.) I've heard from quite a few p...

I have an application that uses window.open() to generate dynamic popups. Unfortunately, I've had trouble creating the content of the new windows using the standard DOM functions (createElement, appendChild), and I've gone to using document.write() to generate the page. Concretely, how can I go from this: function writePopup() { va...

I have a control that is basically functioning as a client-side timer countdown control. I want to fire a server-side event when the count down has reached a certain time. Does anyone have an idea how this could be done? So, when timer counts down to 0, a server-side event is fired. ...
Let's say we have defined a CSS class that is being applied to various elements on a page. colourful { color: #DD00DD; background-color: #330033; } People have complained about the colour, that they don't like pink/purple. So you want to give them the ability to change the style as they wish, and they can pick their favourite ...
Hi - I'm using this XPath to get the value of a field: //input[@type="hidden"][@name="val"]/@value I get several results, but I only want the first. Using //input[@type="hidden"][@name="val"]/@value[1] Doesn't work. Once I have this, how do I pick up the value in Greasemonkey? I am trying things like: alert("val "+val.snapshotItem...

Is there a way (preferrably using JavaScript) to determine whether a URL is to a SWF or a JPG? The obvious answer is to sniff the filename for ".jpg" or ".swf" but I'm dealing with banners that are dynamically decided by the server and usually have a lot of parameters and generally don't include an extension. so i'm wondering if I co...
A pattern that's started to show up a lot in one of the web apps I'm working are links that used to just be a regular a-tag link now need a popup box asking "are you sure?" before the link will go. (If the user hits cancel, nothing happens.) We've got a solution that works, but somehow we're a web app shop without a Javascript expert, ...
