I have a <textarea id="mytextarea"></textarea>.

Let's say a user typed in there: <hello>, world!

How to get res = "&lt;hello&gt;, world!"; from what user typed?

This code doesn't work:

var res = $('#mytextarea').val().html();

It says:

Uncaught TypeError: undefined is not a function

P.S. var res = $('#mytextarea').val(); works just fine, but I need the text from the textarea became html-escaped.

How to do it with jQuery?

Thank you.

  • Why it is duplicate, if it is not. I saw that question you've mentioned before I asked. I was curious if it is possible to do WITH jQuery. – Haradzieniec Commented Apr 23, 2014 at 18:50

Already answered: Can I escape html special chars in javascript?

function escapeHtml(unsafe) {
    return unsafe
         .replace(/&/g, "&amp;")
         .replace(/</g, "&lt;")
         .replace(/>/g, "&gt;")
         .replace(/"/g, "&quot;")
         .replace(/'/g, "&#039;");
}

var res = escapeHtml($('#mytextarea').val());

Something like this could work:

var res = $("<div/>").text($('#mytextarea').val()).html();
  • demo : http://so.devilmaycode.it/get-html-escaped-text-from-textarea-with-jquery/

use this function that emulate the equivalent php function
