jquery实现点击查看更多内容控制段落文字展开折叠效果

本文实例讲述了jquery实现点击查看更多内容控制段落文字展开折叠效果。分享给大家供大家参考。具体如下:

这里使用jQuery实现的文字展开折叠效果,点击文字后文字内容会完整的显示出来,控制段落来显示文字,不需要的时候,可以再次点击后将内容折叠起来,也就是隐藏了一部分内容。点击查看更多的功能,在很多大网站都有在用,像一些电影简介、产品介绍有时候为了页面的布局效果,常常默认是隐藏了一部分,用户想看的时候可以点击后展开。

运行效果如下图所示:

具体代码如下:

<!DOCTYPE html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>jQuery文本段落展开和折叠效果</title>

<style>

html,body,div,h2,p{margin: 0;padding: 0;}

html{font: 1em Arial, Helvetica, sans-serif;color: #444;}

a{color: #0087f1;}

p{margin-bottom: 5px;}

#container{margin: 0 auto;width: 600px;}

#container h2{font-size: 20px;color: #0087f1;}

#wrap{position: relative;padding: 10px;overflow: hidden;}

#gradient{width: 100%;height: 35px;background: url() repeat-x;position: absolute;bottom: 0;left: 0;}

#read-more{padding: 5px;border-top: 4px double #ddd;background: #fff;color: #333;}

#read-more a{padding-right: 22px;background: url() no-repeat 100% 50%;font-weight: bold;text-decoration: none;}

#read-more a: hover{color: #000;}

</style>

<script type="text/javascript" src="jquery-1.6.2.min.js"></script>

<script type="text/javascript">

$(function(){

var slideHeight = 75; // px

var defHeight = $('#wrap').height();

if(defHeight >= slideHeight){

$('#wrap').css('height' , slideHeight + 'px');

$('#read-more').append('<a href="#">点击查看更多。。</a>');

$('#read-more a').click(function(){

var curHeight = $('#wrap').height();

if(curHeight == slideHeight){

$('#wrap').animate({

height: defHeight

}, "normal");

$('#read-more a').html('点击隐藏');

$('#gradient').fadeOut();

}else{

$('#wrap').animate({

height: slideHeight

}, "normal");

$('#read-more a').html('点击查看更多。。');

$('#gradient').fadeIn();

}

return false;

});

}

});

</script>

</head>

<body>

<div id="container">
