Get attribute of element selected by element name

Get attribute of element selected by element name

Hi!
I am just working on a project where i have to replace the href-attributes of all links by another string. The problem is, that i need the old href-attribute to generate the new one, and i have no idea how to get it

i tried it with something like this, but it doesnt work:

$(document).ready(function(){

$("a").attr({"href":"javascript:follow("+ $(this).attr("href") +")";

});

I know there is some way to do it but i forgot it and i looked up the whole internet for it and didnt find it, so i hope you can help me
