輸入兩個(gè)window.open語(yǔ)句為什么不會(huì)打開(kāi)兩個(gè)窗口？

?function?openWindow()
{
????var?open=confirm("是否打開(kāi)新頁(yè)面?");
????if(open==true)
????{
????var?newsite=prompt("打開(kāi)什么網(wǎng)站","http://idcbgp.cn/");
????//?通過(guò)輸入對(duì)話框，確定打開(kāi)的網(wǎng)址，默認(rèn)為?http：//idcbgp.cn/
???window.open(newsite,'_blank','width=400,height=500,menubar=yes,toolbar=yes');
???window.open(newsite,'_blank','width=400,height=500,menubar=yes,toolbar=yes');
????}
????else?alert("bye");
}
