thinkphp+echarts生成地图数据

今天记录下实现地图的动态数据加载功能。

具体代码如下：

HTML代码:

JavaScript代码:

后端代码：

public function dt() {    
        if (!empty($_POST)) {
            $nianji = I('nianji');
            $where['nianji'] = $nianji;
            $cengci = I('cengci');
            if ($cengci) {
                $where['cengci'] = $cengci;
            }
            $count = M('Zhaosheng');
            $data = $count->field('lys as name,count(id) as value')->where($where)->order('lys asc')->group('lys')->select();
            //show_bug($data);exit;
            $this->ajaxReturn($data);
        }       
        $this->display();
    }

生成的地图效果如下：
