We use XMLHttpRequest object to read/write data from server side.
This example based on that.
It is simple to understand.
Read Text file from JavaScript
function
read()
{
var txtFile = new
XMLHttpRequest();
txtFile.open("GET",
"http://localhost:9122/Text.txt",
true);
txtFile.onreadystatechange = function ()
{
if (txtFile.readyState === 4)
{
// Makes sure the document
is ready to parse.
if (txtFile.status === 200)
{
// Makes sure it's found the
file.
document.getElementById("div").innerHTML
= txtFile.responseText;
}
}
}
txtFile.send(null)
}
HTML
<body onload="read();">
<form id="form1" runat="server">
<div id="div">
</div>
</form>
</body>
