本文實例講述了JavaScript基于Ajax實現(xiàn)不刷新在網(wǎng)頁上動態(tài)顯示文件內(nèi)容的方法。分享給大家供大家參考。具體如下：
!DOCTYPE html>
html>
head>
title>sharejs.com/title>
script>
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 xmlhttp.status==200)
{
document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","ajax_info.txt",true);
xmlhttp.send();
}
/script>
/head>
body>
div id="myDiv">h2>Let AJAX change this text/h2>/div>
button type="button" onclick="loadXMLDoc()">Change Content/button>
/body>
/html>
