Modified based on Jquery. The following are all scripts:

The Code is as follows:

// Word search
Var GLS = {};
GLS. startObj = null;
GLS. isdb = false;
GLS. allow = true;
GLS. isallow = function (){

};
GLS. mousedown = function (evt ){

// Page loading
$ (Document). ready (function (){
$ (Document. body). append ("

$ (Document). mousedown (GLS. mousedown). dblclick (GLS. dblclick). mouseup (GLS. mouseup );
});

Attach CSS/* search */

The Code is as follows:

A. GL_s {width: 68px; height: 20px; display: block; border: solid 1px #2b7ab7; line-height: 20px; padding-left: 18px; color: #084f10; font-size: 12px; font-weight: bold; background: url(search.gif) no-repeat left; text-decoration: none ;}
A. GL_s: link {filter: alpha (opacity = 71);-moz-opacity: 0.7; opacity: 0.7 ;}
A. GL_s: hover {filter: alpha (opacity = 100);-moz-opacity: 1.0; opacity: 1.0 ;}
