xmlhttp異步的例子:
URL:<input name=a value="http://www.microsoft.com" style="width:600px">
<input οnclick="getXML()" type="button" value="得到源代碼">
<input οnclick="if(xh && xh.responseText) {alert(xh.responseText);oDiv.innerHTML=xh.responseText}" type="button" value="顯示源代碼">
<div id=m></div>
}
function getReady()
{
if(xh.readyState==4)
{
if(xh.status==200)
{
oDiv.innerHTML = "完成"
}
else
{
oDiv.innerHTML = "抱歉，裝載數據失敗。原因：" + xh.statusText
}
}
