javascript - window.opener.close() has no effect

1. Parent page window.open() opens a new page

var targetWeb=null;
if(targetWeb){
    targetWeb.focus();
}else{
    targetWeb=window.open('https://segmentfault.com','segmentfault');
}

2. Close the parent page in the child page

window.opener.close();

If it is found that the child page cannot close the parent page, it will prompt: Scripts may close only the windows that were opened by it
But if it is replaced with: window.opener.location.href='https://www.hao123. com' but it works, what is the reason

    The close method can only close the window opened by itself

    <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>

    
尝试了这段代码，在父窗口中直接使用

     myWindow=window.open('','','width=200,height=100');
    myWindow.close();

    可以关掉子窗口，在子窗口中无效。
