当点击apply(submit) button时候会执行php端code (下载一个文件），工作正常。但是点击Link的时候没有下载。我写了个js 用ajax 的 xmlHttp.open 来模拟apply 功能。
有谁帮我看看我的code 谢谢啊！ 附件是所有的code
js code: dl.js
------------------------------------
var xmlHttp = false;
function DownLoadFile()
{
if (xmlHttp != false)
{
var req = "dl.php";
xmlHttp.open( "GET", req, true );
xmlHttp.send( null );
//alert("Download File Dialog");
}
}
function Load ()
{
if (xmlHttp != false)
return;
if ((!xmlHttp) && (typeof XMLHttpRequest != 'undefined'))
xmlHttp = new XMLHttpRequest();
else
{
try
{
xmlHttp = new ActiveXObject( "Msxml2.XMLHTTP" );
}
catch( e )
{
try
{
xmlHttp = new ActiveXObject( "Microsoft.XMLHTTP" );
}
catch( e2 )
{
xmlHttp = false;
}
}
}
}
