    <p>I apologize if this kind of question has already been asked but I have looked through "Related Questions" and I don't think anything in here matches with mine, so please bear with me as I try to present my problem and how am I going to go about this, so here I go.</p> <p>Okay, I will refer you my screenshot. Two of my tables have been generated by using Javascript and one is static and I didn't comment out the tbody tags within a listModulesWithinScene table.</p> <p><a href="http://img852.imageshack.us/i/haildstabletable.jpg/" rel="nofollow noreferrer">http://img852.imageshack.us/i/haildstabletable.jpg/</a> (click in the link to view the image)</p> <p>Here's my cut-down version of my HTML code for those who are interested.

This is the function that I'm trying to call.</p> <pre><code>function ListAllModulesWithinScene(sceneName) {alert("test"); /* The part of the code that I took out fills up the table with the list of modules that are part of the scene, each module having different levels/settings. */ } </code></pre> <p>The expected result is that I want to see the alert message box just to make sure it works before I call out the code to generate the rows of data like say...</p> <pre><code>function ListAllModulesWithinScene(sceneName) { /*listModulesWithinScene = document.getElementById("listModulesWithinScene"); // Delete the tbody tag if it does not exist and create a enw tbody tag. if(listModulesWithinScene.getElementsByTagName("tbody") != null) listModulesWithinScene.removeChild("tbody"); var listModulesWithinScene_tBody = document.createElement("tbody"); var xmlRows = xmlObj.childNodes[2].getElementsByTagName("Scene"); for (var r = 0; r &lt; xmlRows.length; r++) { if (xmlRows[r].getAttribute("name") == sceneName) { var moduleRow = xmlRows[r].getElementsByTagName("Module"); if (moduleRow.length &gt; 0) { var row = document.createElement("tr"); for (var msr = 0; msr &lt; moduleRow.length; msr++) { var moduleRow2 = xmlObj.childNodes[1].getElementsByTagName("Module"); for (var mr = 0; mr &lt; xmlRow2.length; mr++) { if (moduleRow[mr].getAttribute("id") == xmlObj.childNodes[1].childNodes[mr].getAttribute("id")) { var td_id = document.createElement("th"); td_id.appendChild( document.createTextNode(moduleRow.getAttribute("id"))); td_id.setAttribute("id", "listModulesFromScene_row" + r + "_id"); row.appendChild(td_id); var td_name = document.createElement("td"); td_name.appendChild( document.createTextNode(moduleRow2.getAttribute("name"))); td_name.setAttribute("id", "listModulesFromScene_row" + r + "_name"); row.appendChild(td_name); var td_level = document.createElement("td"); td_level.appendChild( document.createTextNode(moduleRow.getAttribute("level"))); td_level.setAttribute("id", "listModulesFromScene_row" + r + "_level"); row.appendChild(td_level); } } } } } } listModulesWithinScene_tBody.appendChild(row); listModulesWithinScene.appendChild(listModulesWithinScene_tBody);*/ } </code></pre> <p>In order to help get a better ideal of how my tables are generated, I want to post my entire code. I could provide more details about my problem but that's all I can provide for now.</p> <p>This is the XMLReaderWriter.js file that I currently have.</p> <p>/* When it comes to loading and saving an XML file, it helps to try to keep the XML file organized and well-formed, so it's best to not to modify the XML file UNLESS you know what you're doing.</p> <p>The structure of an XML file is as follows:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;HomeAutomationInterface&gt; &lt;Setup&gt; &lt;Location longitude="" latitude="" /&gt; &lt;/Setup&gt; &lt;Modules&gt; &lt;!-- The first row is an example. --&gt; &lt;Module id="1" name="module name" level="ON" type="dimmer"&gt; &lt;!-- ... --&gt; &lt;/Modules&gt; &lt;Scenes&gt; &lt;!-- the first row is an example.

I did have some experience with Javascript before I take COP2822, though.</p>

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.
