2、错误原因

var map = function(mapData){
        require(
        [
            'echarts',
            'echarts/chart/map'
        ],
        function (ec) {            
            var mapChart = ec.init(document.getElementById('mapDataChart')); 

            var option = {
                    title : {
                        text: '',
                        x : 'center',
                        y : 'top'
                    },
                    tooltip : {
                        trigger: 'item',
                        formatter: '{a}<br/>{b}:{c}个'
                    },
                    legend : {
                        show:true
                    },
                    dataRange: {
                        min: 0,
                        max: 1000,
                        calculable : true
                    },
                    series : [
                              {
                                  name: '',
                                  type: 'map',
                                  mapType: 'china',
                                  data:mapData,
                                  showLegendSymbol:true
                              }
                          ],
                          animation: true
                };

            // 为echarts对象加载数据 
            mapChart .setOption(option); 

        });
    }

由于echarts中的map没有legend属性，导致报错

3、解决办法

var map = function(mapData){
        require(
        [
            'echarts',
            'echarts/chart/map'
        ],
        function (ec) {            
            var mapChart = ec.init(document.getElementById('mapDataChart')); 

            var option = {
                    title : {
                        text: '',
                        x : 'center',
                        y : 'top'
                    },
                    tooltip : {
                        trigger: 'item',
                        formatter: '{a}<br/>{b}:{c}个'
                    },

                    dataRange: {
                        min: 0,
                        max: 1000,
                        calculable : true
                    },
                    series : [
                              {
                                  name: '',
                                  type: 'map',
                                  mapType: 'china',
                                  data:mapData,
                                  showLegendSymbol:true
                              }
                          ],
                          animation: true
                };

            // 为echarts对象加载数据 
            mapChart .setOption(option); 

        });
    }
