Javascript is a programming or scripting language primarily used for client-sided programming in web browsers. It can also be used as a server-side programming language but this is generally used less often. Javascript was originally created by Netscape for their browser Netscape Navigator, and is now an implementation of the ECMAScript standard. It is typically used in web browsers for form validation, floating navigation, AJAX and other nifty things to make web pages more interactive.
If the text is too wide to fit into a container, a nice solution can be to have ellipsis to show there’s more information available. While not currently part of the official HTML specifications, it is possible to have ellipsis defined in CSS and it works for Internet Explorer, Safari, Chrome and Opera. It doesn’t work for Firefox but there’s a workaround that can be done with jQuery.
This post shows how to modify the right-click menu with jQuery – it’s possible to either completely disable right-click context senstive menus or replace them with a custom dialog which is applicable to the application. This can be done to the page as a whole or just a specific element.
Click handlers can be assigned to elements easily with jQuery so when the element is clicked some particular action is run. This post looks at how to add a click handler to an element, explains how adding multiple click handlers will fire all of them, and then how to remove the click events.
I use the YUI Compressor to minify Javascript and CSS files. By default it will remove all comments from the files but there is a simple solution to retaining comments in files, which is often necessary for example when preserving copyright and license terms of use etc.
Javascript functions can be passed as few or as many parameters as you like – the exact number of parameters specified in the function declaration is not exactly what must be passed in. This post shows how to set a default value for a parameter if it’s not passed in.
I was making some changes to an Apache configuration this morning to ensure mod_deflate was compressing CSS and Javascript files and discovered I’d either documented the content-type for Javascript incorrectly, or the Apache version and Linux distro I used at the time served Javascript differently.
