Answer 1

I suppose you're generating the html. If so, you can use attribute selector with begins-with operator.

$('[id^=t]').val('some value');

Note that this sets value for all elements which have their ids beginning with t . So be careful when using ids starting with t and if you know before hand the number after t , then you can just target that element.

$('#t' + id).val('some value');
