<div>
var cellregex = new RegExp(/(.*)_\d$/);<br />
var c = &quot;someid_2_0_3&quot;;<br />
var s = c.match(cellregex);<br />
alert (s);<br />
<br />
This returns: someid_2_0_3,someid_2_0<br />
<br />
How do i get it to only return the second value (someid_2_0)

I see, it is returning an array. Thanks.

<div>
You don't need a regex for this. Sting operations would do well.<br />

<pre><code id="code-20-41254805-1">str.substring(1, str.lastIndexOf('_') - 1)</code></pre>
Characters from 1st position to one_position before the last occurrence of '_' - 1.

<div class="content wysiwyg-content">
I have an id that i want to match such that the last &quot;_&lt;digit(s)&gt;&quot; is ignored.<br />
For eg, if i have an id=&quot;someid_2_0_3&quot;, the match should return &quot;someid_2_0&quot;.<br />
If the id=&quot;anotherid_31_2&quot;, the match should return &quot;anotherid_31&quot;.
