怎么实现彩票走势图，采用js+mvc+html技术来实现
序言
最近闲来无事，研究下怎么去开发双色球的走势图，觉得还是蛮有意思的，用MVC+JS+HTMl来实现的。做了非常多的走势图，还可以进行选号，还做了一些工具来帮助选号，O(∩_∩)O哈哈~纯粹个人兴趣来做的。下面来详细介绍怎么去实现的，还是相当有技术含量的。
实现出来效果
以上随便挑选了4个效果图，一起实现了20多种的效果，就不一一展示了。
怎么实现这走势图
查询条件的实现
function GetcxqsSelect() { var obj = document.getElementById('cxqs'); obj.options.add(new Option("最新10期", "10")); obj.options.add(new Option("最新20期", "20")); obj.options.add(new Option("最新30期", "30", true, true)); obj.options.add(new Option("最新50期", "50")); obj.options.add(new Option("最新80期", "80")); obj.options.add(new Option("最新100期", "100")); obj.options.add(new Option("最新150期", "150")); obj.options.add(new Option("最新200期", "200")); obj.options.add(new Option("最新300期", "300")); obj.options.add(new Option("2003年", "2003")); obj.options.add(new Option("2004年", "2004")); obj.options.add(new Option("2005年", "2005")); obj.options.add(new Option("2006年", "2006")); obj.options.add(new Option("2007年", "2007")); obj.options.add(new Option("2008年", "2008")); obj.options.add(new Option("2009年", "2009")); obj.options.add(new Option("2010年", "2010")); obj.options.add(new Option("2011年", "2011")); obj.options.add(new Option("2012年", "2012")); obj.options.add(new Option("2013年", "2013")); obj.options.add(new Option("2014年", "2014")); obj.options.add(new Option("2015年", "2015")); obj.options.add(new Option("2016年", "2016")); obj.options.add(new Option("2017年", "2017")); obj.options.add(new Option("2018年", "2018")); obj.options.add(new Option("2019年", "2019")); var myDate = new Date(); var tYear = myDate.getFullYear(); if (tYear > 2019) obj.options.add(new Option("2020年", "2020")); if (tYear > 2020) obj.options.add(new Option("2021年", "2021")); if (tYear > 2021) obj.options.add(new Option("2022年", "2022")); if (tYear > 2022) obj.options.add(new Option("2023年", "2023")); if (tYear > 2023) obj.options.add(new Option("2024年", "2024")); if (tYear > 2024) obj.options.add(new Option("2025年", "2025")); if (tYear > 2025) obj.options.add(new Option("2026年", "2026")); if (tYear > 2026) obj.options.add(new Option("2027年", "2027")); if (tYear > 2027) obj.options.add(new Option("2028年", "2028")); if (tYear > 2028) obj.options.add(new Option("2029年", "2029")); if (tYear > 2029) obj.options.add(new Option("2030年", "2030")); if (tYear > 2030) obj.options.add(new Option("2031年", "2031")); if (tYear > 2031) obj.options.add(new Option("2032年", "2032")); }
<tr> <td height="35" bgcolor="#FFFFFF" valign="top"> <div align="center"> 查询 <select name="cxqs" id="cxqs"> </select> <input type="button" name="zuobiao" value="开始查询" onclick="clientssq()"> </div> </td> </tr>
怎么实现表格下发的标记选号功能。
实现的样式：
function Style(obj) {
debugger;
if (obj.style.backgroundColor == "") {
obj.style.backgroundColor = "#dd0000";
obj.style.color = "#FFFFFF";
} else {
obj.style.backgroundColor = "";
obj.style.color = "#ffffff";
}
}
html代码如下：
for (var i = 0; i < 5; i++) {
html += '<tr title="点击空格可以帮助记录选号" align="center" class="chart_record">'
html += '<td></td>'
html += '<td width="19"></td>'
html += '<td width="19"></td>'
html += '<td width="19"></td>'
html += '<td width="19"></td>'
html += '<td width="19"></td>'
html += '<td width="19"></td>'
html += '<td></td>'
html += '<td onclick="Style(this)">01</td>'
html += '<td onclick="Style(this)">02</td>'
html += '<td onclick="Style(this)">03</td>'
html += '<td onclick="Style(this)">04</td>'
html += '<td onclick="Style(this)">05</td>'
html += '<td onclick="Style(this)">06</td>'
html += '<td onclick="Style(this)">07</td>'
html += '<td onclick="Style(this)">08</td>'
html += '<td onclick="Style(this)">09</td>'
html += '<td onclick="Style(this)">10</td>'
html += '<td onclick="Style(this)">11</td>'
html += '<td onclick="Style(this)">12</td>'
html += '<td onclick="Style(this)">13</td>'
html += '<td onclick="Style(this)">14</td>'
html += '<td onclick="Style(this)">15</td>'
html += '<td onclick="Style(this)">16</td>'
html += '<td onclick="Style(this)">17</td>'
html += '<td onclick="Style(this)">18</td>'
html += '<td onclick="Style(this)">19</td>'
html += '<td onclick="Style(this)">20</td>'
html += '<td onclick="Style(this)">21</td>'
html += '<td onclick="Style(this)">22</td>'
html += '<td onclick="Style(this)">23</td>'
html += '<td onclick="Style(this)">24</td>'
html += '<td onclick="Style(this)">25</td>'
html += '<td onclick="Style(this)">26</td>'
html += '<td onclick="Style(this)">27</td>'
html += '<td onclick="Style(this)">28</td>'
html += '<td onclick="Style(this)">29</td>'
html += '<td onclick="Style(this)">30</td>'
html += '<td onclick="Style(this)">31</td>'
html += '<td onclick="Style(this)">32</td>'
html += '<td onclick="Style(this)">33</td>'
html += '<td></td>'
html += '<td></td>'
html += '<td></td>'
html += '<td></td>'
html += '<td></td>'
html += '</tr>'
}
这样就可以实现标记号码功能。
计算连号
function checkdata(arr, num) { var bool = false; for (var i = 0; i < arr.length; i++) { if (arr[i] - num == 1 || arr[i] - num == -1) { bool = true; break; } } return bool; }
计算重号
function array_diff(array1, array2) { var o = {};//转成hash可以减少运算量，数据量越大，优势越明显。 for (var i = 0, len = array2.length; i < len; i++) { o[array2[i]] = true; } var result = []; for (i = 0, len = array1.length; i < len; i++) { var v = array1[i]; if (o[v]) continue; result.push(v); } return result; }
还是有非常多的算法，比如每个号码出现的次数。
这个都是在JS实现，统计每个号码出现的次数。
var arr = [count1, count2, count3, count4, count5, count6, count7, count8, count9, count10, count11, count12, count13, count14, count15, count16, count17, count18, count19, count20, count21, count22, count23, count24, count25, count26, count27, count28, count29, count30, count31, count32, count33]; var max = Math.max.apply(null, arr); var unitcount = 50.00 / max; html += '<tr align="center" bgcolor="#ffffff">' html += '<td height="60">统计</td>' html += '<td></td>' html += '<td></td>' html += '<td></td>' html += '<td></td>' html += '<td></td>' html += '<td></td>' html += '<td></td>' html

计算每个号码出现次数，并且显示红色柱状图效果，以上即是实现的源码。
包括计算和值、大小比、奇偶比、尾和等等都有实现，相对而言还比较复杂。
相对而言实现竖三还是比较复杂的，如下：
var temp1 = []; var temp2 = []; if (parseInt(i) + 2 < data.length) { var arr1 = [data[i].R1, data[i].R2, data[i].R3, data[i].R4, data[i].R5, data[i].R6]; var arr2 = [data[parseInt(i) + 1].R1, data[parseInt(i) + 1].R2, data[parseInt(i) + 1].R3, data[parseInt(i) + 1].R4, data[parseInt(i) + 1].R5, data[parseInt(i) + 1].R6]; var arr3 = [data[parseInt(i) + 2].R1, data[parseInt(i) + 2].R2, data[parseInt(i) + 2].R3, data[parseInt(i) + 2].R4, data[parseInt(i) + 2].R5, data[parseInt(i) + 2].R6]; temp1 = repetition(arr1, arr2); temp2 = repetition(temp1, arr3); } var temp3 = []; var temp4 = []; if (i > 0 && parseInt(i) + 1 < data.length) { var arr1 = [data[parseInt(i) - 1].R1, data[parseInt(i) - 1].R2, data[parseInt(i) - 1].R3, data[parseInt(i) - 1].R4, data[parseInt(i) - 1].R5, data[parseInt(i) - 1].R6]; var arr2 = [data[i].R1, data[i].R2, data[i].R3, data[i].R4, data[i].R5, data[i].R6]; var arr3 = [data[parseInt(i) + 1].R1, data[parseInt(i) + 1].R2, data[parseInt(i) + 1].R3, data[parseInt(i) + 1].R4, data[parseInt(i) + 1].R5, data[parseInt(i) + 1].R6]; temp3 = repetition(arr1, arr2); temp4 = repetition(temp3, arr3); } var temp5 = []; var temp6 = []; if (i > 1 && i < data.length) { var arr1 = [data[parseInt(i) - 2].R1, data[parseInt(i) - 2].R2, data[parseInt(i) - 2].R3, data[parseInt(i) - 2].R4, data[parseInt(i) - 2].R5, data[parseInt(i) - 2].R6]; var arr2 = [data[parseInt(i) - 1].R1, data[parseInt(i) - 1].R2, data[parseInt(i) - 1].R3, data[parseInt(i) - 1].R4, data[parseInt(i) - 1].R5, data[parseInt(i) - 1].R6]; var arr3 = [data[i].R1, data[i].R2, data[i].R3, data[i].R4, data[i].R5, data[i].R6]; temp5 = repetition(arr1, arr2); temp6 = repetition(temp5, arr3); }
function repetition(arr, brr) { //定义一个新的数组，存入重复的数组 var newArr = []; //循环两个数组，外循环循环一圈，内循环一轮，用外循环的一个去和内循环的每一个作比较 //如果相等说明就是重复的，然后再新数组里查找一下，这个数是否存在，如果两个条件都满足，则存入新数组 //循环第一个数组 for (var i = 0; i < arr.length; i++) { //循环第二个数组 for (var j = 0; j < brr.length; j++) { //避免新数组中出现重复的数 if (arr[i] - brr[j] == 0) { newArr.push(arr[i]); } } } //返回新数组 return newArr; } function checkdata(arr, num) { var bool = false; for (var i = 0; i < arr.length; i++) { if (arr[i] == num) { bool = true; break; } } return bool; }
怎么计算斜三走势图
var temp1 = []; if (parseInt(i) + 2 < data.length) { var arr1 = [data[i].R1, data[i].R2, data[i].R3, data[i].R4, data[i].R5, data[i].R6]; var arr2 = [data[parseInt(i) + 1].R1, data[parseInt(i) + 1].R2, data[parseInt(i) + 1].R3, data[parseInt(i) + 1].R4, data[parseInt(i) + 1].R5, data[parseInt(i) + 1].R6]; var arr3 = [data[parseInt(i) + 2].R1, data[parseInt(i) + 2].R2, data[parseInt(i) + 2].R3, data[parseInt(i) + 2].R4, data[parseInt(i) + 2].R5, data[parseInt(i) + 2].R6]; temp1 = repetition(arr1, arr2, arr3,1); } var temp2 = []; if (i > 0 && parseInt(i) + 1 < data.length) { var arr1 = [data[parseInt(i) - 1].R1, data[parseInt(i) - 1].R2, data[parseInt(i) - 1].R3, data[parseInt(i) - 1].R4, data[parseInt(i) - 1].R5, data[parseInt(i) - 1].R6]; var arr2 = [data[i].R1, data[i].R2, data[i].R3, data[i].R4, data[i].R5, data[i].R6]; var arr3 = [data[parseInt(i) + 1].R1, data[parseInt(i) + 1].R2, data[parseInt(i) + 1].R3, data[parseInt(i) + 1].R4, data[parseInt(i) + 1].R5, data[parseInt(i) + 1].R6]; temp2 = repetition(arr1, arr2, arr3,2); } var temp3 = []; if (i > 1 && i < data.length) { var arr1 = [data[parseInt(i) - 2].R1, data[parseInt(i) - 2].R2, data[parseInt(i) - 2].R3, data[parseInt(i) - 2].R4, data[parseInt(i) - 2].R5, data[parseInt(i) - 2].R6]; var arr2 = [data[parseInt(i) - 1].R1, data[parseInt(i) - 1].R2, data[parseInt(i) - 1].R3, data[parseInt(i) - 1].R4, data[parseInt(i) - 1].R5, data[parseInt(i) - 1].R6]; var arr3 = [data[i].R1, data[i].R2, data[i].R3, data[i].R4, data[i].R5, data[i].R6]; temp3 = repetition(arr1, arr2, arr3,3); }
function repetition(arr, brr, crr,index) { //定义一个新的数组，存入重复的数组 var newArr = []; //循环两个数组，外循环循环一圈，内循环一轮，用外循环的一个去和内循环的每一个作比较 //如果相等说明就是重复的，然后再新数组里查找一下，这个数是否存在，如果两个条件都满足，则存入新数组 //循环第一个数组 for (var i = 0; i < arr.length; i++) { //循环第二个数组 for (var j = 0; j < brr.length; j++) { for (var x = 0; x < crr.length; x++) { //避免新数组中出现重复的数 if ((arr[i] - brr[j] == 1 && brr[j] - crr[x] == 1 && arr[i] - crr[x] == 2) || (arr[i] - brr[j] == -1 && brr[j] - crr[x] == -1 && arr[i] - crr[x] == -2)) { if (index == 1) { newArr.push(arr[i]); } if (index == 2) { newArr.push(brr[j]); } if (index == 3) { newArr.push(crr[x]); } } } } } //返回新数组 return newArr; } function checkdata(arr, num) { var bool = false; for (var i = 0; i < arr.length; i++) { if (arr[i] == num) { bool = true; break; } } return bool; }
现在已经实现了一些彩票的走势图，未来还会做福彩3D、福彩七乐彩、超级大乐透、体彩排列三、排列五、体彩七星彩等等热门彩票，目前已经在做福彩3D走势，已经实现了一部分功能了。
包括还做了一些工具，比如复试拆分：

结束语
做这双色球走势，纯粹是为了为人的兴趣而已，感觉还是挺有趣的，涉及到很多年的算法和前端的技术，提升自己的前端技术是非常有用的，未来会利用业余时间进行研究，如各位有兴趣可以一起交流，如都有兴趣，下期介绍怎么爬虫双色球的数据和怎么去保存数据，这个也是要做好这个走势图的前提条件，我这个完全在网上进行爬虫下来的历史数据，一般的调用接口都是要收费的，所以逼得自己必须去其他官方的网站去爬取数据，这样就比较方便。
