Question

I’ve got some code for a calculator which I’d now like to add a % to the result if there is a result there.

The current code is

    var margins = num4.split(" ");
    var topMarg = GetIntOrEmpty(margins[0]),
        rightMarg = GetIntOrEmpty(margins[1]),
        bottomMarg = GetIntOrEmpty(margins[2]),
        leftMarg = GetIntOrEmpty(margins[3]);
    console.log(topMarg, rightMarg, bottomMarg, leftMarg);

    var shorthand1 = GetIntOrEmpty (topMarg);
    shorthand1 += ' %';

if shorthand1 is empty I want it to not add the ‘ %’ to it and leave it blank.

Any ideas?

Answer 1

if (shorthand1 !== '')
    shorthand1 += '%';
