Is it possible to download and parse a plain text file from different domain with JavaScript?
I've got this fiddle so far, but I'm stuck figuring out what I'm doing wrong.
Markup:
<div id="clickme">Click me</div>
<div id="result">Result: </div>
Code:
$("#clickme").click(function() {
/* ###################################
NOTE: im on say example.com/test.html but trying
NOTE: to access different_domain_sample.com
*/
var req = new XMLHttpRequest();
var sURL = "http://www.google.com/robots.txt";
req.open("GET", sURL, true);
req.setRequestHeader("User-Agent", "blah/4.2");
req.onreadystatechange = function() {
if (req.readyState == 4) {
$("#result").text("Result is: <pre>" + req.responseText + "</pre>");
}
};
req.send(null);
});

It's because of browsers have implemented a feature called cross-site-scripting-prevention. You could for example do the ajax request on a php file on the same server and in that query the target page using curl.
There are three ways to do this:
