    <p>I currently have a function that increases the height of a text area when a user clicks inside the text area. It increases so the user can view all the contents inside the text area. It works fine currently. But I only managed to make it work one text area at a time. I'd like to change it so that ALL text areas increase at the same time whenever one of them is clicked. If anyone can give me an idea I would appreciate it.</p> <p><strong>Current HTML</strong> </p> <pre><code>&lt;textarea name="xaxis1" id="xaxis1_id" rows="3" cols="20"&gt;report facture credit impot&lt;/textarea&gt; &lt;textarea name="yaxis1" id="yaxis1_id" rows="3" cols="20"&gt;200 123 231 431&lt;/textarea&gt; &lt;textarea name="yaxis2" id="yaxis2_id" rows="3" cols="20"&gt;431 111 666 991&lt;/textarea&gt; </code></pre> <p><strong>Current JavaScript Code</strong></p> <pre><code>$('#xaxis1_id').click(function() { resizeTextArea($('#xaxis1_id')); }); $('#yaxis1_id').keydown(function(e) { resizeTextArea($('#yaxis1_id')); }); $('#yaxis2_id').click(function() { resizeTextArea($('#yaxis2_id')); }); function resizeTextArea(currentTextArea) { var textAreaElements = currentTextArea.val().split('\n'); var b=1; var totalColumns = currentTextArea.attr('cols'); for (x=0;x &lt; textAreaElements.length; x++) { if (textAreaElements[x].length &gt;= totalColumns) b+= Math.floor(textAreaElements[x].length/totalColumns); } b+= textAreaElements.length; var totalRows = currentTextArea.attr('rows'); currentTextArea.attr('rows', b); } </code></pre>

    1. COJust use a jQuery class selector instead of Id selector. Then pass $(this) to the resizeTextArea function

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.
