1.父页面window.open()打开新页面
3
1580var targetWeb=null;
if(targetWeb){
targetWeb.focus();
}else{
targetWeb=window.open('https://segmentfault.com','segmentfault');
}
2.子页面中关闭父页面
window.opener.close();
发现子页面无法关闭父页面，会提示：Scripts may close only the windows that were opened by it
但若换成：window.opener.location.href='https://www.hao123.com' 却可以，请问是什么原因

close 方法只能关闭由自己打开的window
<html>
<body>
<script type="text/javascript">
myWindow=window.open('','','width=200,height=100');
myWindow.document.write("This is 'myWindow'");
myWindow.document.write("<script>window.opener.close()</script>");
myWindow.focus();
myWindow.opener.document.write("This is the parent window");
myWindow.close();
</script>
</body>
</html>
可以关掉子窗口，在子窗口中无效。
