The code is very simple, here is not much nonsense, directly on the source code
The HTML code
<!doctype html>
<html>
<head>
<meta charset="utf-8"/>
</head>
<body>
<button type="button" onclick="show()"> The request data </button>
<script src="ajax.js"></script>
<script>
function show(){
Ajax('read.txt?datetime=new Date.getTime ',function(str){alert(str);},function(){alert(' failed ');})
};
</script>
</body>
</html>
Javascript code
function Ajax(url,fnSucc,fnFaild)
{
//1. Create an ajax object
if(window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
var oAjax=new XMLHttpRequest();
}
else
{// code for IE6, IE5
var oAjax=new ActiveXObject("Microsoft.XMLHTTP");
}
//2. Link server (open connection to server)
//Open (method, file name, asynchronous transfer)
oAjax.open('GET',url,true);
//3. Send
oAjax.send();
//Receive returns
oAjax.onreadystatechange=function()
{
if (oAjax.readyState==4)
{
if(oAjax.status==200)
{
fnSucc(oAjax.responseText);
}
else
{
fnFaild(oAjax.status);
}
};
};
}
The requested file is read.txt
Fill in the content casually
