Question

function escapeHtml(text) {

      return text
        .replace(/\t/g, "")
        .replace(/\n/g, "")
        .replace(/%/g,"")
        .replace(/\s/g, " ")
        .replace(/&/g, "")
        .replace(/</g, "")
        .replace(/>/g, "")
}

can somebody provide me the regex for all the above entities into a single regex?

Can you create example you want, I think your method wrong '<div>something</div>' -> 'divsomething/div' — hong4rc

Did you really mean to replace \s with a space, instead of with an empty string like all the rest? — Barmar

\s is the same as space, \t, and \n. but you already replaced \t and \n earlier. — Barmar

If \s is being replaced with a space, while all the others are being replaced with the empty string, it's not possible with a single regex unless you provide it with a replacer function, which doesn't make much sense - just use two .replaces. To be concise, use a character set:

return text
  .replace(/[\t\n%&<>]/g, '')
  .replace(/\s/g, ' ');

Try this:

text.replace(/[&%$<>\t\s]/g,"");

replace all enter, whitespaces & tabs with \s and \t and character &%$<>
