Another solution could be this:
in html:
<iframe id="frmFile" src="test.txt" onload="LoadFile();" style="display:
none;"></iframe>
in javascript
function LoadFile() {
var oFrame = document.getElementById("frmFile");
var strRawContents =
oFrame.contentWindow.document.body.childNodes[0].innerHTML;
var obj = JSON.parse(strRawContents);
}
However they are all really ugly.. simplest solution is to use jQuery.
