title: Search for particular word using jQuery?
body: <p>I have a script, which let's users submit e message. But I want to restrict some users from posting a particular world, and once that word is used, the form cannot be submitted (return false;) and an alert will be outputted.</p>
  
  <p>So how would I do a word check in jQuery?</p>
  
  <p><em>Example:</em></p>
  
  <p>1) Desired world to be blocked: Pizza</p>
  
  <p>2) User puts this word in the textarea</p>
  
  <p>3) User hits submit, but he used this word beside his other words so form doesn't submit</p>
  
  <p>If jQuery cannot do this, but Javascript can, then I'd also welcome a Javascript solution.</p>
