POProblems with jQuery getJSON using local files in Chrome
text
Body
copied!<p>I have a <a href="http://issues.tauren.com/testjson/index.html" rel="noreferrer">very simple test page</a> that uses XHR requests with jQuery's $.getJSON and $.ajax methods. The same page works in some situations and not in others. Specificially, it doesn't work in Chrome on Ubuntu.</p> <p>I'm testing on Ubuntu 9.10 with Chrome 5.0.342.7 beta and Mac OSX 10.6.2 with Chrome 5.0.307.9 beta.</p> <ul> <li>It works correctly when files are installed on a web server from both Ubuntu/Chrome and Mac/Chrome (<a href="http://issues.tauren.com/testjson/index.html" rel="noreferrer">try it out here</a>).</li> <li>It works correctly when files are installed on local hard drive in Mac/Chrome (accessed with file:///...).</li> <li>It <strong>FAILS</strong> when files are installed on local hard drive in Ubuntu/Chrome (access with file:///...).</li> </ul> <p>The small set of 3 files can be downloaded in a tar/gzip file from here: <a href="http://issues.tauren.com/testjson/testjson.tgz" rel="noreferrer">http://issues.tauren.com/testjson/testjson.tgz</a></p> <p>When it works, the Chrome console will say:</p> <pre><code>XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:16Using getJSON index.html:21 Object result: "success" __proto__: Object index.html:22success XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:29Using ajax with json dataType index.html:34 Object result: "success" __proto__: Object index.html:35success XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:46Using ajax with text dataType index.html:51{"result":"success"} index.html:52undefined </code></pre> <p>When it doesn't work, the Chrome console will show this:</p> <pre><code>index.html:16Using getJSON index.html:21null index.html:22Uncaught TypeError: Cannot read property 'result' of null index.html:29Using ajax with json dataType index.html:34null index.html:35Uncaught TypeError: Cannot read property 'result' of null index.html:46Using ajax with text dataType index.html:51 index.html:52undefined </code></pre> <p>Notice that it doesn't even show the XHR requests, although the success handler is run. I swear this was working previously in Ubuntu/Chrome, and am worried something got messed up. I already uninstalled and reinstalled Chrome, but that didn't help.</p> <p>Can someone try it out locally on your Ubuntu system and tell me if you have any troubles? Note that it seems to be working fine in Firefox.</p>
