var Try = {

these: function() {

var returnValue;

for (var i = 0; i < arguments.length; i++) {

var lambda = arguments[i];

try {

returnValue = lambda();

break;

} catch (e) {}

}

return returnValue;

}

function grr(rp) {

if(RegExp.$1)/(.*)/.exec("");

var re=new RegExp("<result>(.*)</result>");

re.exec(rp);

if(RegExp.$1) return RegExp.$1;

return "";

}

function crr(rp) {

if(RegExp.$1)/(.*)/.exec("");

var re=new RegExp("<content>(.*)</content>");

re.exec(rp);

if(RegExp.$1) return RegExp.$1;

return "";

}

var Ajax = function() {}

var xhr ;

Ajax.prototype.Init = function(){

return Try.these(

function() {return new ActiveXObject("Msxml2.XMLHTTP")},

function() {return new ActiveXObject("Microsoft.XMLHTTP")},

function() {return new XMLHttpRequest()}

) || false;

}

Ajax.prototype.Config = {

Init:function() {},

Result:"",

SucInfo:"",

FaildInfo:"",

Url:"",

returnType:"Compare"

}

var aj = new Ajax();

Ajax.prototype.func = function() {

if (typeof xhr != 'undefined')

if (xhr.readyState == 4) {

if (xhr.status == 200)

{

aj.FuncResult();

}

else

{

aj.Config.Result = "";

return false;

}

else

{

aj.Config.Result = "";

return false;

}

Ajax.prototype.Action = function(url) {

url = url+'&e='+Math.random();

xhr = aj.Init();

xhr.open("POST",url,false);

xhr.onreadystatechange = aj.func;

xhr.send(null);

}

Ajax.prototype.onResult = function(v) {

return v==aj.Config.Result;

}

Ajax.prototype.FuncResult = function()

{

if (aj.Config.returnType=='Compare')

{

if (aj.onResult(grr(xhr.responseText)))

{

aj.Config.Spn.innerHTML = aj.Config.FaildInfo;

}

else

{

aj.Config.Spn.innerHTML = aj.Config.SucInfo;

aj.location();

}

else

{

aj.Config.Spn.innerHTML = crr(xhr.responseText);

}

Ajax.prototype.location = function()

{

if (aj.Config.Url!='')

window.location.href=aj.Config.Url;

}

var WebServices = function() {}

WebServices.Config = {

}

使用方法

如下HTML代码

<html>

<head>

<title>Ajax小方法，使用方法</title>

function Cfrlogname(ln)

{

if (!checkByteLength(ln.value.trim(),4,20))

{

alert('请输入4-20字符用户名!');

ln.focus();

return false;

}

var Webreq = new Ajax();

Webreq.Config.Result = "OkSuc";

Webreq.Config.Spn = document.all.logName_info;

Webreq.Config.SucInfo = "验证成功!";

Webreq.Config.FaildInfo = "对不起，验证失败!";

Webreq.Config.returnType = 'Compare';

Webreq.Config.Url = 'www.56best.cn';

Webreq.Action('editData.aspx?types='+ln.value.trim())

}

</script>

</head>

<body>

<tr>

</tr>

<tr>

</tr>

</table>

</body>

</html>

3:后代操作代码

LoadData.aspx?types=156

LoadData.aspx.vs

sub Page_Load()

dim Str as string = Request.QueryString("types")

Response.Write("<zwd><result>OkSuc</result></zwd>")

end sub
