Replace # and \s from a string using JavaScript

Question

I am trying to replace # and space from a string if it has these two characters.

This is for markdown previewer.

var t = document.getElementById("textbox");

var h1 = (t.value === "/#\s/") ? t.value.replace(/^[#\s]/, "") : t.value;
console.log(h1);

How do I solve this problem?

t.value === "/#\s/" is true when t.value is literally and exactly /#s/ only — Jaromanda X

If you want to categorically strip all pounds signs and spaces, then you should be using:

//var t = document.getElementById("textbox");
var t = "Hello#World Goodbye";
t = t.replace(/[# ]/g, "");
console.log(t);

Note the character for space, is just space, not \s, which means all whitespace (including things like newlines and tabs).

Try

let h1 = textbox.value.replace(/#| /g, '');
console.log(h1);

<input id="textbox" value="H a v e Nice#Day###">
