How to add parameters to a URL that already contains other parameters and maybe an anchor

Question

I\'m wondering how I can add a new parameter to an existing url. The problem is: the url may also contain an anchor.

For example:

http://www.example

@freedev answer is great, but if you need something very simple (to insert key=value pair to the url and assume that key doesn't already exist), there's a much faster way to do it:

var addSearchParam = function(url,keyEqualsValue) {

    var parts=url.split('#');
    parts[0]=parts[0]+(( parts[0].indexOf('?') !== -1) ? '&' : '?')+keyEqualsValue;
    return parts.join('#');

}

Example usage: addSearchParam('http://localhost?a=1#hash','b=5');
