                                                                刚开始学javascript写的东西，window.open打开心窗口默认屏幕居中，大家看了别笑弱智，给点鼓励！

function CenterWindow(url,w,h){
var x = window.screen.availHeight;
var y = window.screen.availWidth;
var CenterTop=(x-h)/2;
var CenterLeft=(y=w)/2;
window.open(url,"","width="+w+",height="+h+",top="+CenterTop+",left="+CenterLeft);
}

点我试试看
