I always wanted to add an AJAX-style search to my website - thanks to this nice plugin, I could easily add it. It needed some customization, though, because the colors would not quite fit my theme. Also, I wanted to make my site XHTML valid, but unfortunately, the plugin uses two attributes which are not within the standard: “autocomplete” and “placeholder”.

I realized that I do not need “placeholder”, and I turn on the autocomplete feature with JavaScript, instead - I simply added it to the ls.init function within the live_search.js:

init:function() {
document.getElementById("s").setAttribute("autocomplete","off");
(...)

I actually got this JavaScript trick from the Mozilla Wiki.

This plugin is awesome - thanks for providing it!

Thanks to Stefan for implementing my suggested “show all” feature!
