echarts3地图实现点击某省市区域跳转到相应页面

在用echarts3绘制地图成功后（可参考：http://www.cnblogs.com/yyyyd/p/8274564.html），在js部分加上以下代码：

myEcharts.on('click', function(params) {//设置点击事件
                var province = params.name;//获取选中省市的省市名称
                switch(province) {
                    case '新疆':
                        location.href = 'http://www.baidu.com';//测试效果：选中新疆并触发点击事件后跳转到百度首页
                        break;
                    case '西藏':
                        location.href = '';
                        break;
                    case '云南':
                        location.href = '';
                        break;
                    case '广西':
                        location.href = '';
                        break;
                    case '广东':

ps:当选项较多时使用switch-case 比 if-else快
