Question

我在window close事件上显示警告对话框。如果用户点击Cancel控件停留在同一页面上，或者如果用户点击Okay，他就会导航到所需的页面。
我想收集对话框的值意味着用户是否点击了Cancel或Okay。我在外部javascript中编写了以下代码

    $(document).ready(function()
    {
        window.onbeforeunload = askConfirm;

        function askConfirm()
        {
            if (flag)
            {
                // Message to be displayed in Warning.
                return "Your unsaved data will be lost.";
            }       
        } 
    }

我如何收集价值？

Answer 1

<script type="text/javascript">

            window.onbeforeunload = function (evt) {

                return "Are you sure to close?";

            }

        </script>

修改在窗口关闭时从用户那里获取响应代码

<body onUnload = "CheckIt ()" > ... </body> <script> function CheckIt () { var response = confirm ("Are you closing.."); alert (response); // do whatever for response. } </script>
