[WSG] More on forms

[coder]

Hi all,

I've been looking at stuff like this  (check for these chars and disable 
submit button if present):


function check(node)
 {
  var re = new RegExp('[\?\\[\\]]', 'g');
  document.getElementById('sub').disabled = re.test(node.value);
 }

What I'm asking now is, is there an equivalent function using words instead 
of characters?  I would like to make words such as 'ranking' 'SEO' 'search' 
'engine'  etc disable the submit button. I've looked, but can't find 
anything. As you'll have guessed, I'm no good at JS!


Thanks,

Bob

In a regular expression bar will match bar while [bar] will match b or 
a or r. Just don't use the square brackets.

(You should also use regular expression literals ( /bar/ instead of new 
RegExp(bar) ) as they avoid having to escape things for regex and then escape 
them again for the string.)
