Simple application of AJAX, including js popping up DIV layer, layer dragging, and ajax background reading data! Note that the getinfo.asp file is saved in utf-8 format. You can write and read database code in getinfo.asp! function createobj() {
if (window.ActiveXObject) {
return(new ActiveXObject(Microsoft.XMLHTTP));
}
else if (window.XMLHttpRequest) {
return(new XMLHttpRequest());
}
}
function personalInfo() {
var oBao=createobj();
var cont=document.getElementById(person_detial);
var cont_a=document.getElementById(person_content);
cont.style.display='block';
cont.style.cursor='pointer';
cont_a.innerHTML=Please wait, loading...;
var my_url=getinfo.asp?+Math.random();
oBao.open(get,my_url,true);
oBao.onreadystatechange=function(){
if(oBao.readyState==4){
if(oBao.status==200){
cont_a.innerHTML=oBao.responseText;
}else{
cont_a.innerHTML=An error occurred, the error code is: +oBao.status;
}
}
}
oBao.send();
}
