這篇文章給大家介紹使用JQuery怎么實現鏈式調用，內容非常詳細，感興趣的小伙伴們可以參考借鑒，希望對大家能有所幫助。
jquery是一個簡潔而快速的JavaScript庫，它具有獨特的鏈式語法和短小清晰的多功能接口、高效靈活的css選擇器，并且可對CSS選擇器進行擴展、擁有便捷的插件擴展機制和豐富的插件，是繼Prototype之后又一個優秀的JavaScript代碼庫，能夠用于簡化事件處理、HTML文檔遍歷、Ajax交互和動畫，以便快速開發網站。
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。
