function openWindow(){
var myCon = confirm();
if(confirm = 1)
{
var Adr = prompt("确定打开的网站","http://www.imooc.com");
window.open(Adr,'_test','meanbar = no,toolba=no,width = 400,hight = 500);
}
}
var myCon = confirm();
if(confirm = 1)
{
var Adr = prompt("确定打开的网站","http://www.imooc.com");
window.open(Adr,'_test','meanbar = no,toolba=no,width = 400,hight = 500);
