How to get the file using it's URL in Javascript?

How do I get input using Javascript in a bookmarklet?

• I am trying to write some code to append a URL with some text. So that the action would be - click a button, get input from user, go to output. I have tried writing this (I have removed the real URL): "javascript:spam_check=location.href(C… TEXT INPUT HERE)" - this may not display correctly here, so will also explain below. So you can see, I want to insert a username at the end of this URL using javascript - xxxxxx.co.uk/something/?user=, when a user click the bookmarklet, they can enter a username, it will then go to the desired page. I'm a bit of a noob, this should be easy, I've tried some different solutions but can't get it right. Cheers!!
