如何判断弹出窗口是否已完全加载

Question

Is it possible to tell from a parent window if a popup window has fully loaded? 是否可以从父窗口判断弹出窗口是否已完全加载？

<body>
  <div id="btn">display web page</div>
    <div id="somediv">
    </div>
  </body>

I write the following script to determine if the pop up is already loaded, but it does not work. 我编写以下脚本来确定弹出窗口是否已加载，但是它不起作用。

<script>
 $("#somediv")[0].onload = function(){
            alert('loaded');
            console.log("rr");
        };
</script>

Is this what you want? 这是你想要的吗？

<body>
  <div id="btn">display web page</div>
  <div id="somediv">
  </div>
</body>

$("#somediv").load("a.html", function(){
    alert('loaded');
    console.log("rr");
});

Is this what you were looking for? 这是您要找的东西吗？

<html>
    <head>
        <script type="text/javascript">
            var winPop;

            function OpenWindow() {
                winPop = window.open("popupwin.html");
                CheckWinStatus();
            }

            function CheckWinStatus() {
                try {
                    asdf = winPop.document.body;
                    WindowLoaded();
                }
                catch(e) {
                    setTimeout("CheckWinStatus()",1000);
                }
            }

            function WindowLoaded() {
                alert(winPop.document.title);
            }

        </script>
    </head>
    <body>
        <form name="Form1">
            <input type="button" name="B1" value="Open" onclick="OpenWindow()">
        </form>
    </body>
</html>

The function OpenWindow() is called when button b1 is clicked. 单击按钮b1时将调用函数OpenWindow() 。
Inside OpenWindow() , a popup window popupwin.html is made to open. 在OpenWindow()内部，将打开一个弹出窗口popupwin.html 。
CheckWinStatus() checks whether the popup has fully loaded or not. CheckWinStatus()检查弹出窗口是否已完全加载。 It has a timeout value of 1000 ms. 超时值为1000毫秒。
When the popup window has fully loaded, WindowLoaded() is called. 弹出窗口完全加载后，将调用WindowLoaded() 。 This is where you would perform your popup dependent action. 您将在此处执行依赖于弹出窗口的操作。
