what's syntax for uncheck the checkbox for in specific row?

I'm new to JQuery, i want to uncheck certain row in the repeater grid.

I got this work, this will uncheck all checkbox for me.

$('span.chkIncRows input').attr('checked', false);     

This works for me, if I want to uncheck row #2 checkbox from the repeater, without passing row number.

$('span.chkIncRows input')[2].checked开发者_如何学运维 =false;           

I don't know the syntax to uncheck the checkbox, if i want to pass in the row number into checkbox.

For example: I really want to do something like this, but it doesn't work.

$('span.chkIncRows input')[rowNumber].checked =false;  

Thanks advance for your help. Annie

Use the :eq selector:

$('span.chkIncRows input:eq(1)').attr('checked', true);  

Note that it's zero-based, so input:eq(1) selects the second input.

Try:

$('span.chkIncRows input').eq(2).attr('checked', false);

It's hard to say without knowing exactly what your HTML looks like. [edit] Also check @SLaks' answer; it depends on the context for the operation. The selector (':eq()') is handy but it means you have to glue the string together (which admittedly is not difficult).

Use the eq selector: http://api.jquery.com/eq-selector/

$('span.chkIncRows input:eq(1)').attr('checked', false);
