Load when the browser is open

[Merandel]

I made a special button that thru the use of this js shows the server status using a api, my problem is that i cant make this thing to automaticly load the first time you open the browser, you have to actually click the button otherwise it doesnt start runing.\[code\]function checkStatus(event){ jQuery.getJSON("url",function(data){ var button = document.getElementById("ServStat"); if ( data.status == '1') { jQuery('#ServStat').addClass('online').removeClass('offline'); button.label = 'Online'; } else { jQuery('#ServStat').addClass('offline').removeClass('online'); button.label = 'Offline' } });}\[/code\]Any ideas are welcome and thanks in advance.
