Question

Given textarea is a textarea element with id \'textareabox\', how can I check if it contains a string within it?

var textarea = document.getElementById(\'tex         


        

Answer 1

You could do something like this:

var textarea = document.getElementById('textareabox').value;

if (texarea.match(word) != null) {
    // do some stuff
}

A better regex than what I did but I don't know regex all that well (forgive me regex ignorance).
