Removing removeAttr() and adding ? href.

Removing removeAttr() and adding ? href.

Hi,
 
I'm looking to remove an "Href" from a link, but add it back later. So

<

li class="home"><
a href =" # " >Some Click Through</ a ></li>


"$('.home a').removeAttr('href');"
 
would remove the href, and the link wouldn't click through, but when I need it to click again what do I do?
Do I use attr() some how? Thanks for any help.
