        var dom = document.getElementById('container');
        var myChart = echarts.init(dom, null, {
            renderer: 'canvas',
            useDirtyRect: false
        });
        var app = {};
        var option;

        $.get('需要加载的SVG路径', function (svg) {
            echarts.registerMap('flight-seats', { svg: svg });
            option = {
                tooltip: {},
                geo: {
                    map: 'flight-seats',
                    roam: true,
                    selectedMode: 'multiple',
                    layoutCenter: ['50%', '50%'],
                    layoutSize: '100%',
                    tooltip: {

                    emphasis: {
                        itemStyle: {
                            color: undefined,
                            borderColor: 'green',
                            borderWidth: 2

                    },
                    select: {
                        itemStyle: {
                            color: 'green'
                        },
                        label: {
                            show: false,
                            textBorderColor: '#fff',
                            textBorderWidth: 2
                        }
                    }
                }
            };

            myChart.setOption(option);
        });

        if (option && typeof option === 'object') {
            myChart.setOption(option);
        }

        window.addEventListener('resize', myChart.resize);
    </script>
</body>

</html>

2. VS Code打开SVG文件，对需要交互的元素设置name

3.根据需要自主控制元素选中/未选中。

//设置元素选中
myChart.dispatchAction({
    type:"geoSelect",
    geoIndex: 0,
    name: "test"
});

//设置元素取消选中
myChart.dispatchAction({
    type:"geoUnSelect",
    geoIndex: 0,
    name: "test"
});

SVG文件设置

在需要交互的元素上添加name属性
只有这些 SVG 元素可以被命名： rect、circle、line、ellipse、polygon、polyline、path、text、tspan、g。
支持多个元素以相同的名称命名，这样它们能被同时高亮、选中。
