                for (let i = 0;i<trs.length;i++){
                    // 获取tr下所有的td

                let row = $(this).prevAll().length;
                // 获得当前tr下td的名字
                let name = $("#table tbody").find("tr").eq(row).find("td").eq(0).text();

                myEcharts.dispatchAction({ type: 'hideTip', name:name});//选中高亮
            });
        });
    </script>
</body>
</html>

实现联动的js代码：

  1. 实现鼠标点击环形图表格高亮
            // 设置echarts的点击事件
            myEcharts.on('click',function (params) {
                // 获取table下所有的tr
                let trs = $("#table tbody tr");
                for (let i = 0;i<trs.length;i++){
                    // 获取tr下所有的td
                    let tds = trs.eq(i).find("td");
                    // 先把之前的标记的success去掉
                    $("#table tbody tr").eq(i).removeClass('success');
                    // 如果点击图示的名字和table下的某一个行的第一个td的值一样
                    if (params.name == tds.eq(0).text()){
                        //设置success状态
                        $("#table tbody tr").eq(i).addClass('success');
                        // 跳转到页面指定的id位置
                        $("html,body").animate({scrollTop:$("#table tbody tr").eq(i).offset().top},1000);
                    }
                }
            });
  1. 实现鼠标悬停在表格上环形图高亮
			// 当鼠标落在tr时，显示浮动
            $("#table tbody").find("tr").on("mouseenter",function () {
                // 获得当前匹配元素的个数
                let row = $(this).prevAll().length;
                // 获得当前tr下td的名字
                let name = $("#table tbody").find("tr").eq(row).find("td").eq(0).text();
                // 设置浮动
                myEcharts.dispatchAction({ type: 'showTip',seriesIndex: 0, name:name});//选中高亮
            });
            // 当鼠标移开tr时候取消浮动
            $("#table tbody").find("tr").on("mouseleave",function () {
                // 获得当前匹配元素的个数
                let row = $(this).prevAll().length;
                // 获得当前tr下td的名字
                let name = $("#table tbody").find("tr").eq(row).find("td").eq(0).text();
                // 设置浮动
                myEcharts.dispatchAction({ type: 'hideTip', name:name});//选中高亮
            });

其中需要注意的几个地方：

  • 获取某表格中所有的tr

    let trs = $("#table tbody tr");

  • 遍历所有的tr，trs.length是该列表的长度。

  • 获取某一行的所有单元格td

    let tds = trs.eq(i).find("td");

  • 修改某处的CSS样式（移除或添加）

    $("#table tbody tr").eq(i).removeClass('xxx');

    $("#table tbody tr").eq(i).addClass('xxx');

  • 跳转页面的制定id位置

    $("html,body").animate({scrollTop:$("#table tbody tr").eq(i).offset().top},1000);

app.py的路由代码

@app.route('/liandong')
def liandong():
        data1 = []
        data2 = []
        sql = 'select usertype,count(*) from user_type group by usertype'
        db = mysql_util.MysqlHelper(database='spark', user='root', passwd='000429', port=3306, host='127.0.0.1')
        data = db.all(sql)
        for i in data:
                data1.append(i[0])
                data2.append(i[1])
        print("图表联动（路由）！")
        return render_template("liandong.html", data=data, data1=data1, data2=data2)

utils/mysql_util.py 数据库操作工具代码

import pymysql
class MysqlHelper():
    def __init__(self, host, port, database, user, passwd, charset='utf8'):
        self.host = host
        self.port = port

        self.conn = pymysql.connect(host=self.host, port=self.port, db=self.db,
                                    user=self.user, passwd=self.password, charset=self.charset)
        # 创建游标对象
        self.cursor = self.conn.cursor()

    # 关闭
    def close(self):
        self.cursor.close()
        self.conn.close()

    # 增加、修改、删除命令语句
    def cud(self, sql, params=(), msg="操作成功！"):
        try:
            self.open()
            # 处理逻辑数据，传入sql语句以及参数化
            self.cursor.execute(sql, params)
            # 执行事务
            self.conn.commit()
            self.close()
            # 这样可以修改输出的操作成功信息提示
            print(msg)
            return msg
        except Exception as e:
            self.conn.rollback()
            print("错误", e)
            return e

    # 查询所有数据,多个值
    def all(self, sql, params=()):
        try:
            self.open()
            self.cursor.execute(sql, params)
            data = self.cursor.fetchall()
            self.close()
            return data
        except Exception as e:
            print("错误", e)

if __name__ == '__main__':
    db = MysqlHelper(database='spark', user='root', passwd='000429', port=3306, host='127.0.0.1')
    sql = 'select * from user_type;'
    data = db.all(sql)
    print(data)

​可以看到这种方式是存在瑕疵的，最完美的实现方式应该是不设置点击事件，而是全部由鼠标悬停来触发图表变化。

最终实现效果：

中国软件杯---电力客户行为分析---图表联动echarts-demo（flask）-LMLPHP

3）实现南丁格尔玫瑰图和表格图表联动（联动实现方式二）

INSERT INTO user_top5 SELECT *,(times-std_times)*money_aver AS std_top5 FROM elec_0 ORDER BY std_top5 DESC LIMIT 5;

可能最有潜力成为高价值型用户的TOP5

数据来源：用每个用户自己的缴费次数 减去 全部用户的平均缴费次数 然后乘以该用户自己的平均缴费金额 最后取前五名

实现联动的js代码

<!--  图表联动 -->
<script>
    //鼠标悬浮在表格上，玫瑰图高亮！
            // 当鼠标落在tr时，显示浮动
            $("#table tbody").find("tr").on("mouseenter",function () {
                // 获得当前匹配元素的个数
                let row = $(this).prevAll().length;
                // 获得当前tr下td的名字
                let name = $("#table tbody").find("tr").eq(row).find("td").eq(0).text();
                // 设置浮动
                myChart.dispatchAction({ type: 'showTip',seriesIndex: 0, name:name});//选中高亮
            });
            // 当鼠标移开tr时候取消浮动
            $("#table tbody").find("tr").on("mouseleave",function () {
                // 获得当前匹配元素的个数
                let row = $(this).prevAll().length;
                // 获得当前tr下td的名字
                let name = $("#table tbody").find("tr").eq(row).find("td").eq(0).text();
                // 设置浮动
                myChart.dispatchAction({ type: 'hideTip', name:name});//选中高亮
            });
    //----------------------------------------------------------------------------------------
    //鼠标悬停玫瑰图上，表格高亮！
            myChart.on('mouseOver', function (params) {
                let trs=$("#table tbody").find("tr")
                let row = trs.prevAll().length; //4 这里获取的是该tr之前的行数，一共5行，如果是第5行则最多有4行
                for (i=0;i<=row;i++){
                    let name = $("#table tbody").find("tr").eq(i).find("td").eq(0).text();
                    if(name == params.name){
                        $("#table tbody").children().eq(i).css("background", "rgba(176, 196, 222,1)")
                    }
                }
            });

            myChart.on('mouseOut', function (params) {
                let trs=$("#table tbody").find("tr")
                let row = trs.prevAll().length;
                for (i=0;i<=row;i++){
                    let name = $("#table tbody").find("tr").eq(i).find("td").eq(0).text();
                    if(name == params.name){
                        $("#table tbody").children().eq(i).css("background", "rgba(176, 196, 222,0.1)")
                    }
                }
            });
</script>

这个方法实现了悬停动态效果，使用 myChart.on('mouseOver', function (params)和myChart.on('mouseOut', function (params) 鼠标状态监听方法代替了 myEcharts.on('click',function (params) 的鼠标点击事件方法。

最终实现效果：
