jQuery and Repeater

Each row in the repeater should have a unique numeric identifier of some sort.  For example you should have something like:

    _txtQuantity1
    _txtQuantity2
    _txtQuantity3
    etc.....

Then you just need to find the unique identifier (i.e. row index) using javascript.  Then once you have the identifier, you should be able to locate the price and total textboxes fairly easily.  Something like this:

$('[id*="_txtQuantity"]').blur(function ()
{
       var rowIndex = this.id.substring(12, 1);  //should strip out the "_txtQuantity" just leaving the number
       var quantity = $(this).val();
       var price = $('[id*="_txtPrice' + rowIndex + '"]').val();
       $('[id*=_txtTotal' + rowIndex + '"]').val(quantity * price);
});
