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.
I’ve been using the jQuery Facebox dialog plugin in a couple of my projects and one thing that annoys me by default is the loading screen appears at an arbitrary position on the page and then becomes centered after the content has loaded; it’s the moving after load I find messy. This post has a simple change that needs to be made to the Facebox code so it auto-centers the loading dialog.
When showing an inline popup in a webpage (as opposed to a popup window) it is nice to grey out the background a little to highlight that the user should now interact with the popup rather than the webpage. This post shows how to do the necessary HTML and CSS to achieve this and tomorrow’s post will look at implementing the greyed out background with the jQuery Facebox plug-in.
A few weeks ago I posted how to clear a form with Javascript and in this post look at how to do the same thing but using jQuery, which makes the code required to do it much more condensed.
Javascript does not have built-in functions to trim strings so they need to be defined either by using a Javascript framework/library such as jQuery which includes a trim function or to define trim functions yourself. This post shows how to create trim() ltrim() and rtrim() functions.
In my last jQuery post I looked at how to set, get and clear cookies with jQuery and now look at how to get a list of all the cookies that have been set. This is not jQuery specific and will work with just regular Javascript.
jQuery’s function append() can be used to add text or html to an element. It’s very easy to use and this post shows some example code and has a working example where you can type in some text that will be appended to a div.
