打开新窗口

function openWin(openUrl,w,h){
    var iWidth     = w || 1200; //弹出窗口的宽度;
    var iHeight = h || 600; //弹出窗口的高度;
    var iTop     = (window.screen.availHeight-30-iHeight)/2; //获得窗口的垂直位置;
    var iLeft     = (window.screen.availWidth-10-iWidth)/2; //获得窗口的水平位置;
    window.open(openUrl,"","height="+iHeight+", width="+iWidth+", top="+iTop+", left="+iLeft);
}
