本文实例分析了jquery中append()与appendto()的用法。分享给大家供大家参考。具体分析如下：
在jQuery的文档操作方法中，append()和appentto()方法执行的任务相同，但是两者也有区别。
1、append()方法：在被选元素的结尾（但仍在元素内部）插入指定的内容。
a、语法：
代码如下:
$(selector).append(content);
其中，参数content是必需的，指定要附加的内容。
b、append能够使用函数给被选元素附加内容，语法为：
代码如下:
$(selector).append(function(index,html));
其中，function()是必需的，参数index和html都是可选的。index表示接收选择器的index位置，html表示接收选择器的当前html。
例子：
代码如下:
<html>
<head>
<script type="text/
javascript
" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(
document
).ready(function(){
$("button").click(function(){
$("p").append(" <b>Hello jQuery!</b>");
});
});
</script>
</head>
<body>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>在每个 p 元素的结尾添加内容</button>
</body>
</html>运行结果如下：
This is a paragraph. Hello jQuery!
This is another paragraph. Hello jQuery!
2、appendto()方法：在被选元素的结尾（但仍在元素的内部）插入指定的内容。但不能使用函数来附加内容。
语法：
代码如下:
$(content).appendto(selector);
例子：
代码如下:
<html>
<head>
<script type="text/javascript" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$("<b> Hello jQuery!</b>").appendTo("p");
});
});
</script>
</head>
<body>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>在每个 p 元素的结尾添加内容</button>
</body>
</html>
运行结果如下：
This is a paragraph. Hello jQuery!
This is another paragraph. Hello jQuery!
