Hi, I am trying to use the Google Maps API in a Coldfusion template that is a border type cflayoutarea container. However the map simply doesn't show up: <cfif isdefined("url.lat")> <cfset lat="#url.lat#"> <cfset lng="#url.lng#"> </cfif> <head> <script src= "http://maps.google.com/maps?file=api&amp;v=2&amp;ke...
Are there any good tools to generate JavaScript? I remember in .NET, there was Script# - don't know its status today. Anyone have experience with any tools? ...
I've been wondering, is there a performance difference between using named functions and anonymous functions in Javascript? for (var i = 0; i < 1000; ++i) { myObjects[i].onMyEvent = function() { // do something }; } vs function myEventHandler() { // do something } for (var i = 0; i < 1000; ++i) { myObjects[i...
I am trying to write some JavaScript RegEx to replace user inputed tags with real html tags, so [b] will become <b> and so forth. the RegEx i am using looks like so var exptags = /\[(b|u|i|s|center|code){1}]((.){1,}?)\[\/(\1){1}]/ig; with the following JavaScript s.replace(exptags,"<$1>$2</$1>"); this works fine for single nested t...

As the title states, I'd be interested to find a safe feature-based (that is, without using navigator.appName or navigator.appVersion) way to detect Google Chrome. By feature-based I mean, for example: if(window.ActiveXObject) { // internet explorer! } Edit: As it's been pointed out, the question doesn't make much sense (obviousl...
RPO 1.0 (Runtime Page Optimizer) is a recently (today?) released component for ASP and Sharepoint that compresses, combines and minifies (I can’t believe that is a real word) Javascript, CSS and other things. What is interesting is that it was developed for ActionThis.com a NZ shop that saw at TechEd last year. They built a site that q...
I've got a site that provides blog-friendly widgets via JavaScript. These work fine in most circumstances, including self-hosted Wordpress blogs. With blogs hosted at Wordpress.com, however, JavaScript isn't allowed in sidebar text modules. Has anyone seen a workaround for this limitation? ...
I have three unordered lists that have been created as Scriptaculous Sortables so that the user can drag items within the lists and also between them: var lists = ["pageitems","rowitems","columnitems"]; Sortable.create("pageitems", { dropOnEmpty: true, containment: lists, constraint: false }); Sortable.create("rowitems", { dropO...
I have a Yahoo map with lots of markers (~500). The map performs well enough until I close the page, at which point it pauses (in Firefox) and brings up a "Stop running this script?" dialog (in IE7). If given long enough the script does complete its work. Is there anything I can do to reduce this delay? This stripped down code exhibits...

Ever wanted to have an HTML drag and drop sortable table in which you could sort both rows and columns? I know it's something i'd die for. There's a lot of sortable lists going around but finding a sortable table seems to be impossible to find. I know that you can get pretty close with the tools that script.aculo.us provides but i ran ...

I have several RequiredFieldValidators in an ASP.NET 1.1 web application that are firing on the client side when I press the Cancel button, which has the CausesValidation attribute set to "False". How can I get this to stop? I do not believe that Validation Groups are supported in 1.1. Here's a code sample: <asp:TextBox id="Userna...
I thought I'd found the solution a while ago (see my blog): If you ever get the JavaScript (or should that be JScript) error "Can't execute code from a freed script" - try moving any meta tags in the head so that they're before your script tags. ...but based on one of the most recent blog comments, the fix I suggested may not work...
I've seen this done in a few sites, an example is artofadambetts.com. The scroll bar on the page scrolls only an element of the page, not the entire page. I looked at the source and havent't been able to figure it out yet. How is this done? ...
I am looking for a good JavaScript library for parsing XML data. It should be much easier to use than the built-in XML DOM parsers bundled with the browsers. I got spoiled a bit working with JSON and looking forward to something on similar lines for XML. ...
What it a good starting point for learning javascript? I'm a well versed C and Java programmer and I have some decent experience in C++, so I'm looking for a few suggestions: What is some good reference material? Is there a particular IDE/editor that is worth looking at? I use vim for C/C++ development and I used IntelliJ Idea for Ja...
It's common to want browsers to cache resources - JavaScript, CSS, images, etc. until there is a new version available, and then ensure that the browser fetches and caches the new version instead. One solution is to embed a version number in the resource's filename, but will placing the resources to be managed in this way in a directory...
