How can I make the Share This button to share the link it stays beside?

so is this Share This button which is doing a pretty good job except the fact that is not sharing the link is staying beside but the link of the page is staying on.

e.g. StackOverflow LinkSHARE THIS button.

question: how can I开发者_如何转开发 make this button to share the link it stays beside, in this case, to share the StackOverflow Link?

I'm pretty much a newbie in JS so if someone can share the entire working code here will be appreciated :)

Thanks folks :) VD

Assuming your link is an anchor (<a... />) and your button is a button (<input type="button" />) you can wrap them both in a container and do something like this:

<div>
  <a href="http://www.stackoverflow.com/">link</a>  
  <input type="button" value="share link" />
</div>

$(document).ready(function() {
  $('input:button').click(function() {
    var url = $(this).parent().find('a').attr('href');
    // do something to share url.
  });
});
