You should use JavaScript (or a server-side script) to properly escape any user input. Here's another JavaScript function you could try

JavaScript

String.prototype.escapeHTML = function () {
  return(
    this.replace(/>/g,'&gt;').
         replace(/</g,'&lt;').
         replace(/"/g,'&quot;')
  );
};
var codeEl = document.getElementById('test');
if (codeEl) {
  codeEl.innerHTML = codeEl.innerHTML.escapeHTML();
}
