Question

i am new with jQuery.. i have a table with a number of boxes in it. I want to grab all the select boxes in the table and loop through them..

I am trying to create a function that does this and it looks like this:

function calculatePercentageTotal(tableName) {
    var total = 0;
    for (i = 0; i <= $("#" + tableName + ' select').length; i++) {
        total += parseInt($("#" + tableName + ' select')[i].val());
    }
    return total;
}

It’s not working though.. any ideas? thanks!

Answer 1

this should do it:

function calculatePercentageTotal(tableName) {
  var total=0;
  $('#'+tableName+' select').each(function(){
    total+= +($(this).val());
  });
  return total;
}
