I have the following html code in my page

<a href="/admin/users/4c6a275ea326cb01f4000001?locale=en">Show
User</a>
</li>
I would like to modify the id part of the href
(4c6a275ea326cb01f4000001)
between the '/admin/users/' string and the '?locale=en' string (always
present) with the value of a variable: var id= selection[0].id;
I know that in order to get the element to be modified , I can write :
$('show_user').firstDescendant()
I would use var link = $('show_user').down('a');
but then .. I don't know how to modify it ..
Now that you have the existing link, and the new bit you want to
replace, it's just a matter of string splitting and re-assembly. If
the /admin/users/ part is always the same, you could do something
really simple like this:
(wrap this whole thing in a test for link's existence, so you don't
get bitten if the HTML changes later)
var new = '/admin/users/' + id + '?' +
link.href.toString().split('?').last();
and finally,
link.href = new;
and you're done.
