2 javascript部分
但此时切换featureGroup需要手动点，那有没有自动挡的方法呢？
这就需要javascript部分了
点开html文件，在script的最底下找到feature_group相关的内容
在后面加上这么几行
var featureGroups = [feature_group_8df8517d8a89c6007b42dd2aadea48b0,feature_group_5a58f9ee265eaa471b5e4e7aa586333a,feature_group_6fd24d0e96225627d8854aa735f3fe78,feature_group_4c8deb7bf4c4f7167afe823deac0d581,feature_group_096c62b8f2bcc94692f5ad56ddf740dc,feature_group_9e343a47b18a0d5dd2abcdc211227e69];var currentGroupIndex = 0;function showNextFeatureGroup() {if (currentGroupIndex > 0) {// 隐藏上一个feature groupfeatureGroups[currentGroupIndex - 1].remove();}if (currentGroupIndex < featureGroups.length) {// 显示当前feature groupfeatureGroups[currentGroupIndex].addTo(map_432a4a2a79d3e5bfe322e27360e2c06b);currentGroupIndex++;} else {// 如果所有feature group都已显示，可以停止定时器clearInterval(interval);}} // 每1秒切换一次feature groupvar interval = setInterval(showNextFeatureGroup, 1000);那么就会从第1个feature group开始 每隔1秒切换到下一个feature group
但这样的问题是，只能走一遍这样的流程，走完了就没了，如何循环播放呢？
修改一下else部分，其他部分不变
function showNextFeatureGroup() {if (currentGroupIndex > 0) {// 隐藏上一个feature groupfeatureGroups[currentGroupIndex - 1].remove();}if (currentGroupIndex < featureGroups.length) {// 显示当前feature groupfeatureGroups[currentGroupIndex].addTo(map_432a4a2a79d3e5bfe322e27360e2c06b);currentGroupIndex++;} else {currentGroupIndex = 0;//重置计数器showNextFeatureGroup();}} 这样就可以一直循环了
