    <p>I'm currently building a RoR webpage. I'm trying to build a checkbox that helps select certain options in a form when checked. And when the check box is unchecked, it will automatically uncheck said selected options.</p> <p>For example:</p> <pre><code> &lt;form id='list'&gt;&lt;br&gt; 1&lt;input type='checkbox' value='1' /&gt; 2&lt;input type='checkbox' value='2' /&gt; 3&lt;input type='checkbox' value='3' /&gt; 4&lt;input type='checkbox' value='4' /&gt; 5&lt;input type='checkbox' value='5' /&gt; CheckAnimal&lt;input type='checkbox' name='checkanimal' onclick='checkAnimal()'&gt;&lt;br&gt; &lt;/form&gt; </code></pre> <p>And JavaScript:</p> <pre><code> &lt;script language='JavaScript'&gt; function checkAnimal () { var values = ['1', '2', '4', '5']; if (checked == false){checked = true}else{checked = false} $("#list").find('[value=' + values.join('], [value=') + ']').prop("checked", true); } &lt;/script&gt; </code></pre> <p>In JavaScript, without <code>if (checked == false){checked = true}else{checked = false}</code>, the options (1,2,4,5) will be selected when clicking on "CheckAnimal" checkbox. However, if I add the code back, the checkbox will not work at all. </p> <p>By the way, these codes only work in JSFiddle and doesn't work in my local environment and I have no idea why.</p> <p>JSFiddle: <a href="http://jsfiddle.net/yddq6/" rel="nofollow">http://jsfiddle.net/yddq6/</a></p> <p>The codes are all in document "_form.html.erb" and Google CDN (jQuery 1.10.2) <code>&lt;head&gt; &lt;script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"&gt;&lt;/script&gt; &lt;/head&gt;</code>) is in the .erb file as well. </p> <p>Please kindly help!</p>

    1. COThank you so much for resolving my issue quickly, guys! I wish I could choose both of you as best answers. Both solutions work perfectly :) I "best answered" Joe since he posted his solution earlier. Thanks again for everything. Really appreciate it!

    2. COAnd do you guys know why the codes don't work in my local environment? I'm using chrome at http://0.0.0.0:3000/ to test the function, and it doesn't work there only in JSFiddle. The codes are inside "_form.html.erb". Appreciate your wizard work!

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.
