谷歌地图上多个动态位置的信息窗口显示不正确

Question

更新新位置数组时，谷歌地图信息窗口无法正确显示详细信息。

参考：调用函数 1 并单击标记，在那里您可以看到信息窗口的详细信息。 但是当我在函数 1 之后尝试函数 2 时，信息窗口显示未定义。 请参阅此处的图像以供参考

注意：这只是一个示例文件，其功能与我的原始文件相同。

Answer 1

清除gmarkers数组时，您不会将infovalue变量设置回 0。

改变：

function rungooglemap(value) {
for(i=0; i<gmarkers.length; i++){
gmarkers[i].setMap(null);
}
nextAddress = 0;        
theNext();           
}

自：

function rungooglemap(value) {
for(i=0; i<gmarkers.length; i++){
gmarkers[i].setMap(null);
}
// empty the array
gmarkers = [];
// set the index for the geocoding loop back to the beginning
nextAddress = 0;        
infovalue = 0;
theNext();           
}

更新的代码片段：

var locations = [];
var markersinfo = [];
var gmarkers = [];
//all events function
function allevents() {
$('#checkinstatus').val('');
for (i = 0; i < gmarkers.length; i++) {
