尝试访问小胡子中的数组 javascript

Question

我正在尝试使用 this.location.coordinates.0:

从 mustache 访问一个数组

<div class="block">
        <label>Location (longitude/latitude):</label> {{location.coordinates.0}}/{{location.coordinates.1}}
</div>

并得到以下错误

ERROR:  POST /abduction/create Error: \views\abduction\abduction-detail.hbs: Parse error on line 4:
...ocation.coordinates.0

模型看起来像这样：

const abductionSchema = new Schema(
  {
    //https://mongoosejs.com/docs/geojson.html
    location: {
      type: {
        type: String, // Don't do `{ location: { type: String } }`
        enum: ['Point'], // 'location.type' must be 'Point'
        required: true
      },
      // Note that longitude comes first in a GeoJSON coordinate array, not latitude.
      coordinates: {
        type: [Number],
        required: true
      }
    },
    locationName: String,
    timeDate: Date,
    pictures: [String],
    description: String,
    reporter: { type: Schema.Types.ObjectId, ref: 'User' }
  },
  {
    // this second object adds extra properties: `createdAt` and `updatedAt`
    timestamps: true,
  }
);
