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.
The title property of anchor tags in HTML show the text in black on a yellow background by default in most browsers, after mousing over the anchor for a second or two. This tutorial will show you how to style the title with CSS using jQuery and a small amount of Javascript and it will appear as soon as the user mouses over the link.
A couple of days ago, I needed to get the current page’s path and script filename with Javascript, excluding the protocol prefix, domain name and any parameters or hashtags which might be present. So here’s another page for future self reference and so I will remember it in the future.
After receiving a number of "creative" ways to reset forms with Javascript on my "clear a form with jQuery" post, I’ve decided to post the correct way to reset a form with Javascript.
A while back I wrote a series dealing with loading content and JSON data with jQuery and AJAX which culminated in the post "Load JSON data with jQuery, PHP and MySQL" which brought all the techniques together and loaded JSON data into select boxes when the first was changed. I was recently asked how to do this using radio buttons instead, which I show how to do in this post.
There is a bug in older versions of TinyMCE when using Webkit based browsers (Google Chrome and Apple’s Safari) which added and failed to remove hidden divs with the id _mcePaste. This post looks at the problem and offers two solutions: upgrade TinyMCE completely, or just upgrade the paste plugin.
I was asked a couple of days ago on my get and set form values with jQuery post how to make a secondary select box appear with jQuery when the first one is changed. The first might contain a list of countries and the second one some cities which changes as the country changes, allowing the user to select both their country and city. This post shows how to do this with several hidden sub-selects, and an earlier post shows how to do it with JSON and AJAX.
