javascript - window.opener.close()无效

Question

1.父页面window.open()打开新页面

var 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

<script type="text/javascript">
myWindow=window.open('','','width=200,height=100');
myWindow.document.write("这是 'myWindow' ");
myWindow.document.write("<script>window.opener.close()</script>");
myWindow.focus();
myWindow.opener.document.write("这是父窗口");
myWindow.close();

可以关闭掉子窗口，在子窗口中无效。
