how to evaluate   in a string? [duplicate]

Question

console.log(document.getElementById('wsk').textContent === "CASE ");
console.log(document.getElementById('wsk').textContent === "CASE ");

<span id="wsk">CASE&nbsp;</span>

Why are the above log both output false? How should I write the value in 3rd and 4th line so it can evaluates to true?

And by the way, on my page if I replace the "$nbsp;" in the span with a real space, it won't get displayed, why?

Answer 1

A non-breaking space (0xA0) is not a normal space (0x20)

Try comparing the actual character:

document.getElementById('wsk').textContent === 'CASE\xA0'
