No more nonsense, let’s just post the code.
The specific code is as follows:
<script>
function openWindow(){
var my=confirm("你要打开窗口吗？")
if(my==true){
var url=prompt("通过输入对话框，确定打开的网址","http://www.imooc.com")
if(url!=null){
window.open('htttp://www.refw.org.cn','_blank','width=300,height=300,scrollbars=no,menubar=no')}
else{
alert('不打开');
} /*if嵌套*/
}
else{
alert("88")
}
}
</script>
<body>
<input type="button" onclick="openWindow()" value="点击">
</body>The code is just a few sentences. If you have any questions, please leave me a message. The editor will reply to you in time!
