    <p>I am trying to set the div to a certain height inside an empty table cell to set the cell to 100% height. (The whole page consists of just the table with no padding.)</p> <p>Here is some relevant code:</p> <pre><code>&lt;table border="0" width="100%"&gt; &lt;tr&gt; &lt;td class="boxmiddleleft"&gt;&lt;/td&gt; &lt;td class="boxmiddlecenter"&gt;&lt;script language="javascript" src="includes/clock.js"&gt;/*clock*/&lt;/script&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="boxbottomleft"&gt;&lt;script language="javascript" src="includes/windowsize.js"&gt;&lt;/script&gt;&lt;div id="divbottomresize"&gt;&lt;/div&gt;&lt;/td&gt; &lt;td class="boxbottomcenter"&gt;&lt;button type="button" onclick="resizeheight();"&gt;Changed the window height? Reset by pressing this button.&lt;/button&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>(With the div im trying to change height called '#divbottomresize')</p> <p>And the JavaScript I am using for this:</p> <pre><code>var element = "divbottomresize"; function resizeheight(element) { var height = 0; var body = window.document.body; if (window.innerHeight) { height = window.innerHeight; } else if (body.parentElement.clientHeight) { height = body.parentElement.clientHeight; } else if (body &amp;&amp; body.clientHeight) { height = body.clientHeight; } element.style.height = ((height - element.offsetTop) + "px"); } </code></pre> <p>If you have any idea what I am doing wrong please could you tell me. Alternatively if you find other code that does what I want feel free to paste or link me. (I do not want to use jQuery if possible.)</p> <p>When I run the code in Chrome and go to 'Inspect Element' I get the error:</p> <blockquote> <p>windowsize.js:12Uncaught TypeError: Cannot read property 'style' of undefined on the line element.style.height = ((height - element.offsetTop) + "px");</p> </blockquote> <p>EDIT: I have changed <code>var element = "divbottomresize";</code> to <code>var element = document.getElementById("divbottomresize");</code> as someone helpfully suggested. This still does not work and I get the same error and no height change.</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.

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