    <p>I have a HTML form containing checkboxes in the form of .. </p> <pre><code>&lt;input type="checkbox" name="range[]" class="range_opts" id="range-1" value="1" /&gt; 1 &lt;br /&gt; &lt;input type="checkbox" name="range[]" class="range_opts" id="range-2" value="2" /&gt; 2 &lt;br /&gt; &lt;input type="checkbox" name="range[]" class="range_opts" id="range-3" value="3" /&gt; 3 &lt;br /&gt; ... ... &lt;input type="checkbox" name="range[]" class="range_opts" id="range-28" value="28" /&gt; 28&lt;br /&gt; &lt;input type="checkbox" name="range[]" class="range_opts" id="range-29" value="29" /&gt; 29&lt;br /&gt; &lt;input type="checkbox" name="range[]" class="range_opts" id="range-30" value="30" /&gt; 30&lt;br /&gt; </code></pre> <p>With this JS Code I Select all or Deselect all checkboxes </p> <pre><code>$('#select_all_ranges').click(function() { $('input[name="range[]"]').each(function() { this.checked = true; }); }); $('#deselect_all_ranges').click(function() { $('input[name="range[]"]').each(function() { this.checked = false; }); }); </code></pre> <p>But I need the functionality where user would be able to have certain checkboxes selected, depending upon the input </p> <pre><code> &lt;input type="text" name="from_range" id="frm_range" /&gt; &lt;input type="text" name="to_range" id="to_range" /&gt; &lt;img src="icon.png" id="range123" /&gt; </code></pre> <p>so if user inputs from 5 to 20 and clicks on icon it checks checkboxes from 5-20. </p> <p>Can you please help me some ideas how this can be achieved. I can alter markup to apply some classes/selecter ids etc if you suggest, if it would make it any easier. And I understand that this functionality is for users having javascript enabled browsers.</p> <p>Thanks.</p>

    1. COJust a quick note: you don't have to loop through all the checkboxes to check each one in your code. This would be a faster equivalent: $('input.range_opts').attr('checked', true);

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.
