根据分辨率让window.open的窗口居中
var popwin;if(screen.width=="640")
{
popwin = window.open("s1.html","name","resizable=yes,scrollbars=no,menubar=no,toolbar=no,width=450,height=400");
}
else if(screen.width=="800")
{
popwin = window.open("s1.html","name","resizable=yes,scrollbars=no,menubar=no,toolbar=no,width=450,height=400");
}
else if(screen.width=="1024")
{
popwin = window.open("s1.html","name","resizable=yes,scrollbars=no,menubar=no,toolbar=no,width=450,height=400");
}
//重新设置窗口大小
popwin.resizeTo("550","500");
//网页正文全文宽
pw = popwin.document.documentElement.scrollWidth-4;
//网页正文全文高
ph = popwin.document.documentElement.scrollHeight-4;
//移动窗口到中心位置
popwin.moveTo((screen.width-pw)/2,(screen.height-ph)/2);
