checking for empty string in jQuery

Question

I have

<table id="table1">
 <tr>
   <td>&nbsp;</td>
 </tr>
</table>

I check for the value in using

$('#table1 tr').find('td').eq(0).text()

this equates to " "

so the check is

$('#table1 tr').find('td').eq(0).text() == " "

While transferring the file to server, a garbage value is inserted between quotes

$('#table1 tr').find('td').eq(0).text() == " A "

using $('#table1 tr').find('td').eq(0).text().trim() also gives " " as the cell contains  

How do I prevent this garbage value from being inserted each time I deploy on server

How are you transferring the file to the server? *What* does insert the garbage? — Bergi, May 09 '14 at 12:24

@user544079: You need to explain in the question more about "*While transferring the file to server...*" and "*...each time I deploy on server*". — Abhitalks, May 09 '14 at 12:40

Instead of text(), try to set HTML().

Try this, for setting value in Table Cell (TD).

$('#table1 tr').find('td').eq(0).html("A");

Try to check:

$.trim($('#table1 tr').find('td').eq(0).text()).length

The trim() will help you here.

the cell contains a . So length comes out 1. How to check for – user544079 May 09 '14 at 12:25
Please try this. $.trim() will remove the extra space. Have you tried this code? – Naveen Chandra Tiwari May 09 '14 at 12:27
