Question

我正在尝试解决为什么我的地图没有显示我在Switch语句中为两个多边形设置的颜色样式。

（JSfiddle here）：

这是我的测试数据：

DELETE /shop/shoppingcarts/E73AC56C-BDF7-11E5-81F1-8E2EDB915C80/items/9876

以下是我的功能：

L.mapbox.accessToken = 'pk.eyJ1IjoiZG9zcyIsImEiOiI1NFItUWs4In0.-9qpbOfE3jC68WDUQA1Akg';
var map = L.mapbox.map('map', 'mapbox.light')
.setView([40, -74.50], 9);

var myData = [{

为什么这两个多边形没有得到我指定的颜色？

Answer 1

好的，所以你在这里遇到了几个问题，我在这个小提琴里为你修好了。 http://jsfiddle.net/hx5pxdt8/

1.您的areaStyle函数未接受Leaflet为您提供的要素参数。

2.您的getAreaColor函数未传递该参数。

3.当你已经在fillColor属性中时，你的switch语句正在返回javascript对象...这意味着你只需要返回颜色字符串，而不是对象。
