how to store a xmlhttprequest into a variable
I have a quick question that you brainy guys perhaps have the answer to. Why does this work
<html>
<head>
<script type="text/javascript">
var xmlhttp;
func开发者_C百科tion loadXMLDoc(url,cfunc)
{
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=cfunc;
xmlhttp.open("GET",url,true);
xmlhttp.send();
}
function myFunction()
{
loadXMLDoc("ajax_info.txt",function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("myDiv").innerHTML=xlmhttp.responseText;
}
});
}
</script>
</head>
<body>
<div id="myDiv"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="myFunction()">Change Content</button>
</body>
</html>
but if I replace
document.getElementById("myDiv").innerHTML=xlmhttp.responseText;
whit this
var txt=xlmhttp.responseText;
document.getElementById("myDiv").innerHTML=txt;
it don't work anymore, txt is
undefined
. How can I store the xlmhttp.responseText into a string, or into a variable that I can perform a search on? Please give an example on how I can do it. Thanks in advance =)
Might be because you have misspelled variable "xmlhttp" - you have "xlmhttp" in your code.
