javascript - Google map 信息窗口左箭头、右箭头传递 TypeError : Cannot read property '__e3_' of undefined?

Question

我有左侧、右侧移动标记的类别明智过滤器标记。在使用右键或左键单击控制台将一个标记移动到另一个标记时，我收到类似 TypeError: Cannot read property '__e3_' of undefined.i 的错误。我已经尝试过要解决这个问题，但我无法解决，请帮我解决这个问题吗？这是我的演示 demo .选择一些值后，例如“This city is aiiiiite”。左右按钮应该可以工作。

Answer 1

当 google.maps.event.trigger 函数的对象找不到或无效时，通常会出现无法读取未定义的属性“__e3_”错误。在您的情况下，指定的错误在两种情况下发生:

1) markerClick 事件被触发，在某些时候你的标记超出了数组范围。
因此，为了防止这种情况，可以将 markerClick 函数替换为:

$scope.markerClick=function(i){
    if (i<0) i=$scope.markers.length-1;
    if (i >= $scope.markers.length) i=0;         
    google.maps.event.trigger( $scope.markers[i], 'click' );
};

正如另一个答案中所建议的

2) 当发生过滤时，由于createMarker函数需要两个参数，因此替换

createMarker(filteredCities[i]);

与

createMarker(filteredCities[i],i);
