?if(mywin==true){
????//?通過(guò)輸入對(duì)話框，確定打開的網(wǎng)址，默認(rèn)為?http：//idcbgp.cn/
??????????var?url=prompt("print?web?enter:","http：//idcbgp.cn/");
??????????if(url!=null){
????//打開的窗口要求，寬400像素，高500像素，無(wú)菜單欄、無(wú)工具欄。
?????????????window.open("http：//idcbgp.cn/","_blank",'width=400px,height=500px,manubar=no,toolbar=no');
??????????}else{
??????????????alert("error!");
??????????}else{
