dojo.io.iframe: Permission denied to access property 'getElementsByTagName'
 
|
Hi guys,
I am trying to load the contents of a cross-domain component from another server, using dojo.io.iframe API; and I am getting the following error: Permission denied to access property 'getElementsByTagName' I did everything as per examples on using dojo.io.iframe, and wrapped the returned data in <textarea>, but I still get this error. Now it looks like cross-domain issue, but isn't working with the cross-domain security restrictions the very point of dojo.io.iframe? You can access the live problem code example at http://www.askonline.net/wp-content/themes/askonline/site-selector3.php Anyway, here is my HTML: <html><body> <script src="http://www.google.com/jsapi"></script> <script>google.load("dojo", "1.7");</script> <script> dojo.config.dojoBlankHtmlUrl = "/blank.html"; dojo.require("dojo.io.iframe"); dojo.ready (function () { dojo.io.iframe.send ({ url: "http://services.askonline.net/ajax/site-selector.mas", content: {callback: "select_site", textwrap: 1}, load: function (data) { alert ("Got:\n\n" + data);}, error: function (e) { alert ("Error: " + e.message);} }); }); </script> </body></html> Here is the response HTML from the site-selector.mas component: <html><body><textarea> <p>Sample response</p> </textarea></body></html> And here is my blank.html: <html><head><script>isLoaded = true;</script></head><body></body></html> The page makes the request, but then is unable to process it. I thought this might have something to do with the CDN-loaded Dojo, but I tried loading it locally, and got the same error. The one thing that seems to be weird is that according to Firebug, blank.html never completes loading, even though I can load it manually by copy-n-pasting the URL into the browser just fine. Am I missing something obvious here? Any help would be much appreciated. Many thanks in advance. ________________________________________________________ Dojotoolkit: http://dojotoolkit.org Reference Guide: http://dojotoolkit.org/reference-guide API Documentation: http://dojotoolkit.org/api Tutorials: http://dojotoolkit.org/documentation [hidden email] http://mail.dojotoolkit.org/mailman/listinfo/dojo-interest |

Is your iframe request cross-domain? If it is, the browser cuts
off all access to the document returned by the iframe request, for security purposes.

And dojo.io.script is the main way to get around cross-domain
restrictions. iframes still have them. If the source of an iframe is a different domain from the rest of the page, the browser cuts off access to the document.

And the main point of dojo.io.iframe was to have a way to upload files
(xhr cannot access the file system to pull files denoted by input fields, but iframes can using native form submit).
