Use javascript to input data from a website
<p>Ive been trying to find a way to input data from a website coded in HTML with a single javascript output on it.  Is there anyway to incorperate whatever text is on the page (blank page with one line string) into a string on a javascript program I write? I have been searching for quite a while and I'm very sorry if this is a repeat question.  Thanks for all you help!</p>
