How to use comparison operator in Javascript for two input values

Question

I want to compare the two input values, just try in javascript, but it\'s not working fine. I\'m using the following code

function check_closing()
{
var opening         


        

Answer 1

Convert the strings to integers before comparison:

function check_closing()
{
    var opening = $('#opening').val();
    var closing = $('#closing').val();
    if(parseInt(opening) > parseInt(closing))
    {
        alert('Opening is greater than Closing. Please enter the correct value');
        $('#closing').val('');
    }
}
