首页 / 脚本样式 / JavaScript / jquery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:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="tiao.aspx.cs" Inherits="qiantaoflash.tiao" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>青苹果条形统计</title> <link href="css/jQuery.spider.poll.css" rel="stylesheet" type="text/css" /><script type="text/javascript" src="js/jquery-1.4.3.min.js"></script><script type="text/javascript" src="js/jQuery.spider.poll-min.js"></script><script type="text/javascript">var data="{root:[{id:"10000",name:"先结婚",value:"50"},{id:"10002",name:"先事业",value:"50"}]}"; var data1="{root:[{id:"10000",name:"人类联盟",value:"60"},{id:"10001",name:"兽人部落",value:"25"},{id:"10003",name:"不死亡灵",value:"15"},{id:"10004",name:"暗夜精灵",value:"10"}]}"; var data2="{root:[{id:"10000",name:"学历",value:"0"},{id:"10001",name:"能力",value:"100"}]}"; $(document).ready(function (){ $("#poll_a").poll("poll1",{ title:"先结婚还是先事业", width:"600px", data:data });$("#poll_b").poll("poll2",{ title:"青苹果魔兽争霸各个种族实力?", titleColor:"red", width:"600px", data:data1, showPoll:true, multiple:true });$("#poll_c").poll("poll3",{ title:"学历重要还是能力重要", titleColor:"blue", width:"600px", data:data2, multiple:false });$("#getPollData1").click(function (){ $("#poll_b").getChecked().each(function (i,n){alert($(n).val()); }); });$("#getPollData2").click(function (){ $("#poll_c").getChecked().each(function (i,n){alert($(n).val()); }); });});</script></head><body> <div id="poll_a"></div><div id="poll_b"></div><div style="text-align:center;"><input type="button" id="getPollData1" value="获得第一个投票的值"/></div><div id="poll_c"></div><div style="text-align:center;"><input type="button" id="getPollData2" value="获得第二个投票的值"/></div></body></html>
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">1 </div> <div class="item">2 </div> <div class="item">3 </div> <div class="item">4 </div> <div class="item">5 </div> <div class="item">6 </div> <div class="item">7 </div> <div class="item" style="width: 1; border: 0; background-color: White"> </div> </div> <div class="control"> <p style="display: none; position: relative">这是一个段落标记</p> <input type="button" value="停下来" id="btn1" /> <input type="button" value="跳起来" id="bnt2" /> </div></body></html>
