It's important to clarify that doing jQuery('#open').click() does not execute the href attribute of an anchor tag so you will not be redirected. It executes the onclick event for #open which is not defined.
You can accomplish the redirect and the ability to cause it with your original jQuery('#open').click() code by giving #open a click event:
jQuery('#open').click( function (e) {
window.location.href = this.href;
});
