You could use the .attr() function:

var foo = 'foo=bar';
$('a#foo').attr('href', function(index, attr) {
    return attr + '?' + foo;
});

or:

$('a#foo').attr('href', function() {
    return this.href + '?' + foo;
});

This doesn't take into consideration what the existing url is – JohnC Jun 26 '14 at 13:09

This will break urls which already have a querystring. Have a look at @JohnC's answer. – Tom Bowers Jun 26 '14 at 13:11

You need to check if there is already a query string before appending items to the url based on the other examples you'd do something like.

var foo = 'foo=bar';
$('a').attr('href', function(index, attr) {
    return attr + (attr.indexOf('?') >=0 ? '&' : '?') + foo;
});

$('a').attr('href', function(i, v) {
    return v + 'text...';
});

@Steffi The index of the element inside the jQuery object - irrelevant in this case. – Šime Vidas Mar 27 '11 at 20:30

If you use it repeatedly try .attr() as:

HTML: <a id='foo' href='#'>I am your father,.. nooooo</a>

var myparams = 'myvar=myvalue';
var myurl = 'TypeThe_NetscapeURL';
$('a#foo').attr('href', function() {
    return myurl + '?' + myparams;
});

Couple of comments: 1.that would work but it's actually overriding the value NOT appending. To append, get the value first $("#foo").attr('href') and then append whatever you need to it. 2. in example above you don't need a function which returns url. simple myurl+'?'+myparams should do it. This is a case of taking a url and appending to it. Setting it to an href is just a byproduct.
