这个可以用,对比一下
1.prompt()括号里只能有一对“”,
2.byebye后面那个括号改成英文格式的
3.Windows.open…………那行后面缺个 }
function openWindow()
{
var open=confirm("是否新建网页?");
if(open==true)
{
var url=prompt("确定打开的网址,默认为 http://www.imooc.com/");
if(url!=null)
{
window.open(url,"_blank",'width=400,height=400,menubar=no,toolbar=no');
}
else
{
alert("byebye");
}
}
else
{
alert("拜拜");
}
}
