JavaScript replace special HTML (&character; format) character in a String

Question

I'm trying to replace the square root symbol which is written in html as "√" ( √ ). I used the following line to replace it with a space but it does not change the String at all.

 dig = document.getElementById("dig").innerHTML; dig = dig.replace(/'√'/g, ' '); console.log(dig);

 <div id="dig">&radic;25</div>

What am I doing wrong here?

This answer is valid if you are accessing the innerText or innerHTML atribute of an Element .

 let s = document.getElementById("sqrt") console.log("Text", s.innerText) console.log(s.innerText.replace(/√/g, "")) console.log(s.innerHTML.replace(/√/g, ""))

 <div id="sqrt"> &radic;2 == 1.4142</div>

As you can see √ gets evaluated and it's value is then √ instead of that. The javascript replace method cannot understand that √ is &radic so you can just replace √ .

Also there is no need to use regex, you can just do the same with "√"
