Menu
Want to get the example below to work with open(“POST”,url,true) instead of open(“GET”,url,true).
When I try that, the program doesn’t seem to do anything when I click the buttons. The last try is commented out.
How do you get it to work with POST ?
[CODE]
<html>
<head>
<title>
</title>
<script language=”javascript” type=”text/javascript”>
<!–
function f(fn,dv)
{
var req=false;
if (window.XMLHttpRequest)
{
req=new XMLHttpRequest();
}
else
{
if (window.ActiveXObject)
{
req=new ActiveXObject(“Microsoft.XMLHTTP”);
}
};
if (req)
{
var fn1=fn+”?t=”+Math.random();
req.open(“GET”,fn1,true);
//req.open(“POST”,fn1,true);
//req.setRequestHeader(“Content-type”,”application/x-www-form-urlencoded”);
req.onreadystatechange=function()
{
if (req.readyState==4 && req.status==200)
{
//var rt2=req.responseText;
var rt2=”<img src=”+req.responseText+”>”;
document.getElementById(dv).innerHTML=rt2;
delete req;
req=null;
}
};
req.send(null);
//req.send();
}
else
{
alert(‘No req.’);
return false;
};
}
–>
</script>
</head>
<body>
<div id=”dv1″>
<form>
<input type=”button” value=”*” onclick=”f(‘aa.txt’,’dv2′);”>
<input type=”submit” value=”*”>
</form>
</div>
<div id=”dv2″>
</div>
