I'm looping through cells in a table row. each cell has a text box in it, and I want to take the value of the text box and push it onto an array.

function dothing() {

        var tds = $('#'+selected+' td');

        var submitvals = new Array();

        tds.each(function(i) {

            var val = $(this).children('input')[0].val();

            submitvals.push(val);

        });

    }

Theres more to the function, but this is all that is relevant. For some reason, when I run this code, I get HTMLInputElement has no method 'val'. I thought that input elements were supposed to have a val() method in jQuery that got the value so this makes no sense. Am I missing something, or doing it wrong?
