Question

I have a select dropdown with id\'s mapped to values. On the onChange event I want to redirect to the same url but with \'id=value\' appended to the querystring.

How do

Answer 1

This works like a charm:

jQuery.redirect = function( url ) {
   window.location.replace( url );  
};
$( "#selector" ).change( function() {
    var href = window.location.href.substring( 0, window.location.href.indexOf( '?' ) );
    $.redirect( href + '?id=' + $( this ).val() );
} );
