jQuery and Repeater
Posted on 2011-03-04
If the user inputs a numeric value into the quantity text box, then I would like to set the price and total textboxes to "0.00"
for that row only.
Please see the screen shot, all the textboxes in all rows changed.
How can I limit it by row?
$(document).ready(function
$("[id$='_txtQuantity']").
var quantity = $("[id$='_txtQuantity']").
if (isNumeric(quantity)) {
$("[id$='_txtPrice']").val
$("[id$='_txtTotal']").val
}
});
});
function isNumeric(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
for that row only.

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"]').
{
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);
});
_txtQuantity1
_txtQuantity2
_txtQuantity3
etc.....
