function include(path){
var a=document.createElement("script");
a.type = "text/javascript";
a.src=path;
var head=document.getElementsByTagName("head")[0];
head.appendChild(a);
}
include("http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js")

<script> <BR>function include(path){ <BR>var a=document.createElement("script"); <BR>a.type = "text/javascript"; <BR>a.src=path; <BR>//if (a.readStatus == 200) { <BR>var head=document.getElementsByTagName("head")[0]; <BR>head.appendChild(a); <BR>//} <BR>} <BR>include("http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js") <BR></script>
<script> <BR>$(function(){ <BR>function sendData(url, callback){ <BR>if(!url || typeof url !== 'string'){ <BR>return; <BR>} <BR>url += (url.indexOf('?') > 0 ?
