Hi All,
I am completely new to AJAX.
This is the first program I have come across and I must say I am confused..
Few of my queries are below:
I wrote below code in a notepad and saved as html. But I don't know where to place the "ajax_info.txt" file. It dint work when I placed it in the same folder as the .html file
Also I don't understand and which response are we collecting through xmlhttp.responseText. Because its only on the next line (xmlhttp.open("GET","ajax_info.txt",true) that we actually mention the url/path to which we are trying to connect. So whom are we trying to get response from in : xmlhttp.open("GET","ajax_info.txt",true
I know its tooooo basic but just cant get a hold of it.
<!DOCTYPE html>
<html>
<head>
<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>
