我一直在使用 blockUI 开发一个非常简单的模式，它会弹出并询问用户是否达到一定年龄。我总是尝试先在它自己的页面中开发一段代码以避免冲突，这就是我在这里所做的。我有一个简单的 html/javascript 页面，但它没有按应有的方式运行。

每当页面加载时，它就会出现。然而，当试图解除封锁（即使不使用按钮）时，它不会做任何事情。它只是与加载图标一起坐在那里。

<html>
<head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript" src="jquery.blockUI.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            // A bit of a work-around. BlockUI tries to center based on location of
            // the div. By attaching block to the html tag immediately, we avoid
            // this issue completely.
            $('html').block({
                message: $('#message'),


                centerX: true,
                centerY: true,

                css: {
                    width: '600px',
                    height: '300px',
                    border: '3px solid #FF9900',
                    backgroundColor: '#000',
                    color: '#fff',
                    padding: '25px'
                }
            });

            $('#over').click(function() {
                alert('clicked!');
                $.unblockUI();
                return false;
            });

            $('#under').click(function() {
                $.unblockUI();
                return false;
            });

        });
    </script>
</head>

<body>
<div id="message" style="display:none;">
    <img src="logo.png" border="0" />
    <br />
    <h1>Welcome!</h1>

    You may not view this page unless you are 21 or over.<br />

    <button id="over">I am 21 or over</button>&nbsp;&nbsp;&nbsp;<button id="under">Under 21</button>


</div>
It's dusty under here! Let me be seen!
</body>
</html>

Chrome 的控制台中没有显示任何错误，我真的找不到不应该关闭的原因。

When you call $.unblockUI() try calling it on an element instead, eg. $('html').unblock();:

<div class="body">
    <div id="message" style="display:none;">
        <img src="logo.png" border="0" />
        <br />
        <h1>Welcome!</h1>
        You may not view this page unless you are 21 or over.
        <br />
        <button id="over">I am 21 or over</button>&nbsp;&nbsp;&nbsp;
        <button id="under">Under 21</button>
    </div>
    It's dusty under here! Let me be seen!
</div>

The JS would be: 

$('.body').block({
    message: $('#message'),
    centerX: true,
    centerY: true,
    css: {
        width: '600px',
        height: '300px',
        border: '3px solid #FF9900',
        backgroundColor: '#000',
        color: '#fff',
        padding: '25px'
    }
});
$('#over').click(function () {
    alert('clicked!');
    $('.body').unblock();
    return false;
});
$('#under').click(function () {
    $('.body').unblock();
    return false;
});
