Question

I have this bookmarklet:

javascript:void(window.open(document.links[Math.floor(Math.random()*document.links.length)].href,'_blank'))

It outputs random link from a document full of links.

I want to make it randomisingly output from only some particular links out of many links on a page.
What should I do?

Answer 1

In Firefox, to get all links within selected text:

var x = document.createElement("div");
x.appendChild(window.getSelection().getRangeAt(0).cloneContents());
var links = x.getElementsByTagName('A');

Here is a tip for IE: http://pclancey.com/tutorial/selectsrc/
