You can use indexOf, see the following example here: http://jsfiddle.net/mikhailov/S5jaz/2/

html

<textarea id="txt">
  Here I am
</textarea>

JS

var txt = $('#txt').val();
var word1 = txt.indexOf('Heref') != -1;    // false
var word2 = txt.indexOf('Here I') != -1;   // true

var text = $('#textarea').val();
var regex = /.../;
var found = text.match(regex);
if (found != null){return 1}
