这篇文章主要介绍了jquery中append()与appendto()用法分析,以实例的形式分析了jquery中append()与appendto()的具体语法与详细用法,需要的朋友可以参考下

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>
Copy after login

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>
Copy after login


运行结果如下:

This is a paragraph. Hello jQuery!
This is another paragraph. Hello jQuery!
