本文實例講述了JQuery特殊效果和鏈式調用操作。分享給大家供大家參考，具體如下：
JQuery的特殊效果
fadeOut()淡入
fadeToggle()切換淡入淡出
hide() 隱藏元素
show() 現實元素
toggle() 切換元素的可見狀態
slideDown() 向下展開
slideUp() 向上卷起
slideToggle()依次展開或者卷起某個元素
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title> <style type="text/css"> .box{ width: 300px; height: 300px; background-color: gold; display: none; } </style> <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> <script> $(function () { $('#btn').click(function () { $('.box').fadeIn(1000,'swing',function () { //可以加一個回調函數 alert('done'); }); }) }) </script></head><body><input type="button" name="" value="動畫" id="btn"> <div class="box"></div></body></html>點擊按鈕，元素淡出，完成之后彈出done，不知道為什么，沒有運行出來，可能是瀏覽器的問題。
