jquery如何实现动静态条形统计图？
下图为jquery实现静态条形统计图，在选择题统计中用的比较多。
思路：前台JS实现动态数据效果，后台可以拼接字符串或者用JSON加载数据
代码：

jquery实现动态的条形统计图
代码如下：
页面布局如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<style type="text/css">
*
{
margin: 0 0 0 0;
padding: 0 0 0 0;
}
.container
{
width: 300;
height: 300;
margin: 50 0 0 50;
border: 1px solid green;
float: left;
background-image: url('/images/mubk.jpg');
}
.control
{
width: 280;
height: 80;
float: left;
margin: 50 0 0 10;
border: 1 solid #000000;
}
.item
{
height: 98%;
width: 30px;
border: 1 sollid green;
background-color: #191970;
display: inline-block;
display: inline;
margin-left: 10px;
margin-top: 10px;
text-align: center;
}
</style>
<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
var timer1;
$("#slide>div:odd").css({ 'background-color': '#308014' });
$("#slide>div:even").css({ 'background-color': '#4169e1' });
$("#bnt2").click(function () {
timer1 = setInterval(initDance, 500);
});
$("#btn1").click(function () {
timer1 && clearInterval(timer1);
});
});
function initDance() {
var height = parseInt(280 * Math.random()) + 5;
var box = parseInt(7 * Math.random());
dance(box, height);
}
function dance(box, height) {
if (height) {
$(".item").eq(box).css({ height: height });
var obj = {};
obj["box"] = box;
obj["height"] = height;
return obj;
} else {
return {};
}
}
</script>
</head>
<body>
<div id="slide" class="container">
<div class="item">

</div>
</body>
