Implementing a simple folding menu effect based on jQuery_jquery
The example in this article describes the code to implement a simple folding menu effect using JQuery. Share it with everyone for your reference. The details are as follows:
The screenshot of the running effect is as follows:
Html code is as follows:
<div class="box"> <p>菜单一</p> <ul> <li><a>1111</a></li> <li><a>1111</a></li> <li><a>1111</a></li> </ul> <p>菜单二</p> <ul> <li><a>2222</a></li> <li><a>2222</a></li> <li><a>2222</a></li> </ul> <p>菜单三</p> <ul> <li><a>3333</a></li> <li><a>3333</a></li> <li><a>3333</a></li> </ul> </div>
The plug-in implementation code is as follows:
(function ($) {
$.fn.Fold = function (options) {
//默认参数设置
var settings = {
speed: 300 //折叠速度(值越大越慢)
}
//不为空则合并参数
if (options)
$.extend(settings, options);
//遵循链式原则
return this.each(function () {
//为每个p元素绑定点击事件
$("> p", this).each(function () {
$(this).bind("click", function () {
$(this).next("ul").slideToggle(settings.speed);
});
});
//默认第一个展开，其它折叠
$("> ul", this).hide().first().show();
});
}
})(jQuery);
I won’t explain it here, the notes are all clearly stated.
The sample DEMO is as follows:

<li><a>3333</a></li>
</ul>
</div>
<script src="../js/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="../js/jquery.similar.Fold.js" type="text/javascript"></script>
<script type="text/javascript">

What is 'this' in JavaScript?
Mar 04, 2025 am 01:15 AM
Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
