I have a list of input boxes, now I need to calculate the total of all values entered in input boxes with the following naming convention pre[0],pre[1],pre[2] etc.

Is this possible with Jquery and how?

    @Reigel The problem is that they aren't *exact* duplicate. That one needs it to be triggered on the `blur` event, while this one requires that selector. You **can** conceivably merge them, but keep doing this to subtlety different questions and we'll end up with the jQuery documentation page. – Yi Jiang Sep 13 '10 at 09:31

Would something like this work?

var sum = 0;

$('input[name^="pre"]').each(function(){
    sum += parseFloat(this.value);
});

^= is the Attribute Starts With Selector.

I would do it like this 

var sum = 0;

find("input[name*='pre']").each(function(index) {

sum = sum + this.val();

 })
