There's not such a thing as "pass a parameter to a file". What you can do is to either insert a content script before executing the file, or sending a message after inserting the file. I will show an example for these distinct methods below. <h1>Set parameters before execution of the JS file</h1> If you want to define some variables before inserting the file, just nest <a href="https://developer.chrome.com/extensions/tabs.html#method-executeScript"><code>chrome.tabs.executeScript</code></a> calls: <pre><code>chrome.tabs.executeScript(tab.id, { code: 'var config = 1;' }, function() { chrome.tabs.executeScript(tab.id, {file: 'content.js'}); }); </code></pre> If your variable is not as simple, then I recommend to use <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify"><code>JSON.stringify</code></a> to turn an object in a string: <pre><code>var config = {somebigobject: 'complicated value'}; chrome.tabs.executeScript(tab.id, { code: 'var config = ' + JSON.stringify(config) }, function() { chrome.tabs.executeScript(tab.id, {file: 'content.js'}); }); </code></pre> With the previous method, the variables can be used in <code>content.js</code> in the following way: <pre><code>// content.js alert('Example:' + config); </code></pre> <h1>Set parameters after execution of the JS file</h1> The previous method can be used to set parameters after the JS file. Instead of defining variables directly in the global scope, you can use the <a href="https://developer.chrome.com/extensions/messaging.html">message passing API</a> to pass parameters: <pre><code>chrome.tabs.executeScript(tab.id, {file: 'content.js'}, function() { chrome.tabs.sendMessage(tab.id, 'whatever value; String, object, whatever'); }); </code></pre> In the content script (<code>content.js</code>), you can listen for these messages using the <a href="https://developer.chrome.com/extensions/runtime.html#event-onMessage"><code>chrome.runtime.onMessage</code></a> event, and handle the message: <pre><code>chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) { // Handle message. // In this example, message === 'whatever value; String, object, whatever' }); </code></pre>

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.
