Question

I implemented the following function to compute the total value of a form:

$('tr').each(function(index, element) {
    if( ($(this).find('input.operation').val() == "add") || ($(this).find('select.operation').val()=="add")) {
         total = parseFloat($(this).find('input.subtotal').val( $('input:eq(1)',this).val() * $('input:eq(2)',this).val() ));
         console.log(subtotal);
    } else {
        console.log( $(this).find('input.subtotal').val( $('input:eq(1)',this).val() * $('input:eq(2)',this).val() ) );         
    }
});

But when I see the console log, it only says:

[prevObject: e.fn.e.init[1].....

instead of showing the actual value, so my question is how do I convert from Object to float?

parseFloat doesn’t seem to be working (obviously because it only converts strings to float)

Answer 1

When you set the value it doesn’t return the actual value, it returns the current jQuery object. Set a variable to the result of .val() and print that out instead:

var value = $(this).find('input.subtotal').val( $('input:eq(1)', this).val() * 
           $('input:eq(2)', this).val() ).val();

console.log( value );
