is there an equivalent to "trim" function in Javascript?

[alexfrumkin]

I need to check if the input type text is empty. I can check for emtpy string like in form.txtName.value==&quot;&quot;, but what if someone enters a space or two into it? in VB I would do trim(form.txtName.value)=&quot;&quot;; How do do it using Javascript?<br><br>Thank you for your time and effort.<br><br>Alex

&nbsp;&nbsp;&nbsp;&nbsp;Hmmm...wouldn't it be relatively simple to just have a <FONT FACE=monospace>while...loop</font> JavaScript function that just checks the first character of the string agains a space & deletes it if it is...then do your empty-string checking?<br>&nbsp;&nbsp;&nbsp;&nbsp;The <FONT FACE=monospace>while...loop</font> function should work well to replace the &quot;trim&quot; function you were speaking of <p>-Robherc<br><a href=mailto:robherc@netzero.net>robherc@netzero.net</a><br><a href= shared.freeservers.com/searchmaster.html>SearchMaster Interface...11-in-1</a><br>Wanting to learn Assembler; please e-mail me any tutorials or links for it that are useful to you

and look up charAt, indexOf, and some other ones.&nbsp;&nbsp;This should give you the information you're looking for. <p>REH<br><a href=mailto:hawkdogg@crosswinds.net>hawkdogg@crosswinds.net</a><br><a href=
