I've never worked with javascript before.


I have an awesome idea for a program but it has to be done in javascript.

Basically I need to a variable out of the html source

Like this:
<span class="menu_title">Variable</span>

Then have it written to a text file. All automatically.

So, the variable changes based upon the pages source code. And, is then written to a text file.

Sounds somewhat simple but I don't know javascript. I will continue googling but if someone couple help me it would be very appreciated.

EDIT: So I have found out that you cant write to text from javascript. So now I am looking to see if you can forward the variable to php to write it to a file automatically. The key is not needing to click for it to log. Only grabbing the information must be done in javascript.

Use document.getElementsByClassName('menu_title')[0].innerHTML to get that, and use XMLHttpRequest to forward that variable to a PHP file (if it's not on the same domain, just load an image with that url, it should work.)

Yeah, make sure you don't have that class anywhere else on that page because it might get it instead.

If you want I have a grabbetween function.
