When trying to do a HTTP request using XMLHttpRequest from a local file, it basically fails due to Access-Control-Allow-Origin violation.

However, I'm using the local web page myself, so I was wondering if there is any way to make Google Chrome allow these requests, which are from a local file to a URL on the Internet.

E.g., $.get('') fails when executing in a local file, but I've scripted the page myself and I'm using it myself, so it would be extremely useful if I could suppress it and load the URL.

So, how can I allow Google Chrome to load URLs using XMLHttpRequest from local files?



startup chrome with --disable-web-security

On Windows:

chrome.exe --disable-web-security

On Mac:

open /Applications/Google --args --disable-web-security

This will allow for cross-domain requests.
I'm not aware of if this also works for local files, but let us know !

And mention, this does exactly what you expect, it disables the web security, so be careful with it.

Nope- can't do this with XHR. Same-domain policy is very restrictive there- same host, same port, same protocol. Sorry! You'll have to resort to other tricks (iframes, title manipulation, etc) to get it to work.

You can't pass DOM nodes with Messaging; data must be JSON-serializable, and DOM nodes are not.

Pass only data you really need (e.g. textContent), then reconstruct the node on the other side.

Of course you can! Just use load with an output argument.

x = 1;
save foo;

ls = load('foo.mat');

You didn't include the document ready handler, try this:

    $(function() {
        $("div").css('background-color', 'black');

        $('.click').click(function() {
                {code:"'" + $(this).attr('id') + "'"});
<div class="click" id="red">red</div>
<div class="click" id="blue">blue</div>
<div class="click" id="green">green</div>
<div class="click" id="yellow">yellow</div>

Alternatively you can move your <script> tag to just before the </body> tag so that all HTML is loaded before the javascript.
