Question

So I have an input field, if it’s blank, I want its value to be the words “empty”, but if there is any value inputted, I want the value to be the inputted value. I want to use javascript for this, any idea how this can be done?

UPDATE: Sorry, I don’t think I explained it too well. I don’t mean placeholder text. I mean the captured value of it. So if it’s blank, the captured val() for it should be “empty”, if it’s filled, the captured val() for it should be that val()

If you’re using pure JS you can simply do it like:

var input = document.getElementById('myInput');

if(input.value.length == 0)
    input.value = "Empty";
