Question

我正在尝试基于jQuery创建幻灯片和淡入淡出效果。在添加函数addClass之前，一切正常。但添加此类后，幻灯片和淡入淡出效果消失。

当我在addClass('hide')之后添加FadeSlideToggle.call(box)时，javascript效果会消失。

有人可以帮助我吗？这是代码：

<html>
<head>
    <style type="text/css">
        .box {
            background: red;
            width: 400px;
            position: relative;
            margin-left: auto;
            margin-right: auto;
        }

        .hide {
            display: none;
        }

    </style>
</head>
<body>
    <div class="box">
        <h2>Some Content Here</h2>
        <p>

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

                    opacity: 'toggle',
                    'height': 'toggle'  
                }, 2000);
            };

            $('button').on('click', function(){
                FadeSlideToggle.call(box);
            });

Answer 1

使用完整回调

var box = $('div.box');

function FadeSlideToggle(callback){

    return $(this).animate({
        opacity: 'toggle',
        'height': 'toggle'  
    }, 2000, callback);
};

$('button').on('click', function(){
    FadeSlideToggle.call(box, function() {
         //do something you want
    });
});

其中一个解决方案是使用jQuery UI。

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
    <script type="text/javascript" src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
    <script type="text/javascript">

            var box = $('div.box');

            function FadeSlideToggle(speed){

                return $(this).animate({
                    'opacity': '0',
                    'height': 0 
                }, speed || 2000);
            };

            $('button').on('click', function(){
                FadeSlideToggle.call(box, 5000).addClass('hide', {
                    queue: true
                });
            });

    </script>
