:The definition and usage of the parent selector:

This selector matches elements that contain child elements or text.
Note: Spaces are also considered contained elements.

Grammar structure:

$(":parent")

This selector is generally used in conjunction with other selectors, such as Class selector and Element selector, etc. wait. For example:

$("div:parent").animate({width:"300px"})

The above code can set the width of a div containing text or elements to 300px.
If not used with other selectors, the default state is to be used with the * selector, for example, $(":parent") is equivalent to $("*:parent").

Example code:

Example 1:

 
 
 
 
 
蚂蚁部落 
 
 
 
 
 
我是文本

The above code can set the width of a div containing text or elements to 300 in a custom animation.

Example 2:

<!DOCTYPE html> 
<html> 
<head> 
<meta charset=" utf-8"> 
<meta name="author" content="http://www.softwhy.com/" /> 
<title>蚂蚁部落</title> 
<style type="text/css"> 
div{ 
list-style-type:none; 
width:150px; 
height:30px; 
border:1px solid red; 
} 
span{border:1px solid green;} 
</style> 
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script> 
<script type="text/javascript"> 
$(document).ready(function(){ 
$("button").click(function(){ 
$("*:parent").animate({width:"300px"}) 
}) 
}) 
</script> 
</head> 
<body> 
<div>我是文本</div> 
<div></div> 
<span>大家好</span> 
<button>点击查看效果</button> 
</body> 
</html>

Since the above code does not specify a selector to be used with the :parent selector, it is used with the * selector by default, so the code can contain text and element's width is set to 300px in a custom animated way.
