Body
<p>In the manifest.json file, I declare that I want to inject some scripts, like this:</p> <pre><code>{ "name": "my extension", "version": "1.0", "background_page": "background.html", "permissions": ["contextMenus", "tabs", "http://*.example.com/*"], "content_scripts": [ { "matches": [ "http://*.taobao.com/*", "http://*.yintai.com/*" ], "run_at": "document_idle", "js": ["jquery-1.5.1.min.js","jquery-ui-1.8.13.custom.min.js", "contentscript.js"], "all_frames": true } ] } </code></pre> <p>In the content script, I create an iframe, among other things. It works fine so far. Like this:</p> <pre><code>$('<div id="my_notifier"></div>').appendTo($('body')).html('<iframe src="http://example.com"></iframe>'); </code></pre> <p>The problem is, inside the iframe, it does not inherit anything from the content scripts. If I want to use jQuery, I have to use <code><script src=...</code> to include it again inside the iframe.</p> <p>I prefer not to include jQuery again because I already put it in the extension. I don't want the user to download jQuery again and again on every page that the extension needs to run on.</p> <p>I've tried the attribute <code>"all_frames": true</code>, but it doesn't work.</p> <p>Please advise. Thanks.</p> <p>Edit: I added example.com to the <code>matches</code> attribute like this:</p> <pre><code>"content_scripts": [ { "matches": [ "http://*.taobao.com/*", "http://*.yintai.com/*", "http://*.example.com/*" ], "run_at": "document_idle", "js": ["jquery-1.5.1.min.js","jquery-ui-1.8.13.custom.min.js", "contentscript.js"], "all_frames": true } ] </code></pre> <p>But it does not work.</p> <p>To be clearer, say the contents of the iframe (example.com) is:</p> <pre><code><!DOCTYPE HTML> <html> <head> <title>Untitled</title> </head> <body> <div></div> <script type="text/javascript"> $('div').html('hi'); </script> </body> </html> </code></pre> <p>There will be an error: $ is not defined</p> <p>To make it work, I have to use:</p> <pre><code><!DOCTYPE HTML> <html> <head> <title>Untitled</title> </head> <body> <div></div> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> <script type="text/javascript"> $('div').html('hi'); </script> </body> </html> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
