need help with minor javascript coding for meebo

[hangman21]

meebo instruction are very vague there example to create action button which is basically without the pop up menu


Meebo('addButton', {
id: "button1",
type: "action",
icon: "/images/icon.png",
label: "Hello World",
onClick: function(){ alert("Hello World."); }
});

i just want to know how can i change the onclick: so instead of using an alert i want have an url that opens up a new window?

this is the url i want to use SURFLINE.COM | Global Surf Reports and Forecasts, Live Surf Cams and Coastal Weather

thanks everyone
