    <p>I'm trying to make a chrome extension that will search different cache databases for a given page. However, it's not working as I expect it to.</p> <pre><code>&lt;!DOCTYPE HTML&gt; &lt;html&gt; &lt;head&gt; &lt;script type="text/javascript"&gt; var x; var img = document.getElementsByTagName("img"); for(x in img) { img[x].addEventListener('click',openPage, false); } function openPage(event) { alert("clicked"); var e = event.target; switch(e.alt) { case "WayBack Machine": chrome.tabs.update(tab.id, { url: "http://wayback.archive.org/web/*/" + tab.url }); break; case "Google Cache": if(tab.url.substring(0, 5) == "http:") chrome.tabs.update(tab.id, { url: 'http://webcache.googleusercontent.com/search?q=cache:' + tab.url.substr(7) }); else if(tab.url.substring(0,6) == "https:") chrome.tabs.update(tab.id, { url: 'http://webcache.googleusercontent.com/search?q=cache:' + tab.url.substr(8) }); break; case "Yahoo Cache": // Need the yahoo cache url break; case "Bing Cache": chrome.tabs.update(tab.id, { url: "http://cc.bingj.com/cache.aspx?q=" + tab.url + "&amp;d=4572216504747453&amp;mkt=en-US&amp;setlang=en-US&amp;w=802790a9,218b61b8" }); break; case "Gigablast": chrome.tabs.update(tab.id, { url: "http://www.gigablast.com/get?q=" + tab.url + "&amp;c=main&amp;d=70166151696&amp;cnsp=0" }); break; case "CoralCDN": chrome.tabs.update(tab.id, { url: tab.url + ".nyud.net" }); break; default: // Webcite // Need to send a request, this won't do chrome.tabs.update(tab.id, { url: "http://webcitation.org/query" }); break; } } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;img src="Google Cache.png", alt="WayBack Machine" class="button" id="WayBack Machine" height ="40px" /&gt; &lt;img src="Google Cache.png", alt="Google Cache" class="button" id="Google Cache" height ="40px" /&gt; &lt;img src="Google Cache.png", alt="Yahoo Cache" class="button" id="Yahoo Cache" height ="40px" /&gt; &lt;img src="Google Cache.png", alt="Bing Cache" class="button" id="Bing Cache" height ="40px" /&gt; &lt;img src="Google Cache.png", alt="Gigablast" class="button" id="Gigablast" height ="40px" /&gt; &lt;img src="Google Cache.png", alt="CoralCDN" class="button" id="CoralCDN" height ="40px" /&gt; &lt;img src="Google Cache.png", alt="Webcite" class="button" id="Webcite" height ="40px" /&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>However, it does not even alert(); When I try the code in a jsfiddle.net, it works: <a href="http://jsfiddle.net/RZ2wC/" rel="nofollow">http://jsfiddle.net/RZ2wC/</a></p> <hr> <p>Here is my manifest.json:</p> <pre><code>{ "name": "gCache", "version": "1.1.5", "description": "View the Google Cache of a page", "browser_action": { "default_icon": "icon.png", "default_text": "Google Cache version of this page", "default_popup": "cacheList.html" }, "permissions": [ "tabs" ] } </code></pre> <hr> <p>Any help would be greatly appreciated.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
