    <p>I have a table that lists locations and then allows a user to select 1 or more permissions for that location. I have the following code working that I can select the top row check-box and you can check all the boxes in that column. I'm looking for tips to optimize what I'm doing. You click on the ".all###" check-box and all the ones with a class of ".XXX" get checked. How can I optimize my jquery? I'm still learning and although I got it to work im sure its not the best route. Any help would be appreciated. </p> <p>This is my part of my HTML code</p> <pre><code> &lt;table&gt; &lt;colgroup&gt;&lt;/colgroup&gt; &lt;colgroup&gt;&lt;/colgroup&gt; &lt;colgroup&gt;&lt;/colgroup&gt; &lt;colgroup span="5"&gt;&lt;/colgroup&gt; &lt;thead&gt; &lt;tr&gt; &lt;th class="locationCode"&gt;Location Code&lt;/th&gt; &lt;th class="locationName"&gt;Name&lt;/th&gt; &lt;th class="locationAddress"&gt;Address&lt;/th&gt; &lt;th class="selectOption"&gt;Admin&lt;/th&gt; &lt;th class="selectOption"&gt;Remote&lt;/th&gt; &lt;th class="selectOption"&gt;Support&lt;/th&gt; &lt;th class="selectOption"&gt;Misc&lt;/th&gt; &lt;th class="selectOption"&gt;Logging&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tfoot&gt; &lt;tr&gt; &lt;td&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/tfoot&gt; &lt;tbody&gt; &lt;tr&gt; &lt;th colspan="3" class="grayBackground"&gt;&lt;/th&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="allAdmin admin"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="allRemote remote"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="allSupport support"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="allMisc misc"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="allLogging logging"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;VST&lt;/td&gt; &lt;td&gt;Demo #1&lt;/td&gt; &lt;td&gt;1 Street, City State&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="admin"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="remote"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="support"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="misc"&gt;&lt;/td&gt; &lt;td class="center"&gt;&lt;input type="checkbox" class="logging"&gt;&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>and my jQuery</p> <pre><code> $(function() { $(".allAdmin").change(function() { if ($(this).prop("checked")) { $(".admin").prop("checked", true); return; } $(".admin").prop("checked", false); }); $(".allRemote").change(function() { if ($(this).prop("checked")) { $(".remote").prop("checked", true); return; } $(".remote").prop("checked", false); }); $(".allSupport").change(function() { if ($(this).prop("checked")) { $(".support").prop("checked", true); return; } $(".support").prop("checked", false); }); $(".allMisc").change(function() { if ($(this).prop("checked")) { $(".misc").prop("checked", true); return; } $(".misc").prop("checked", false); }); $(".allLogging").change(function() { if ($(this).prop("checked")) { $(".logging").prop("checked", true); return; } $(".logging").prop("checked", false); }); }); </code></pre>

    1. COWhy do you have 2 classes for each "master" checkbox? `class="allAdmin admin"` would be more understandable as `class="allAdmin"`. I don't think it functionally changes your JavaScript.

Querying!

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).
