如何将自定义字段传递到mapbox-gl js中以在地图上创建点? [英] How to pass custom fields into mapbox-gl js to create points on map?

问题描述

我已经使用mapbox创建了一个地图，并绘制了可以与之交互的多个自定义点.我也在使用Wordpress，并且希望使用高级自定义字段来创建每个点，以便可以由非技术人员轻松地对其进行管理.这些字段都已设置，但是我无法将它们传递到我的php模板中的javascript中.

I've created a map using mapbox and plotted multiple custom points that you can interact with. I am also using Wordpress and want to use advanced custom fields to create each point so they can easily be managed from a non-technical person. The fields are all setup, but I am having trouble passing them into the javascript in my php template.

我尝试使用循环，但无法在javascript中使用循环.这是我用来绘制点的Mapbox代码，并希望通过以下方式使用高级自定义字段:

I've tried using a loop but I can't use the loop inside javascript. Here is my Mapbox code that I am using to plot the points and want to use advanced custom fields with:

var map = new mapboxgl.Map({
    container: 'map',
    style: 'mapbox://styles/coptmarketing/cjvi7hc4602dk1cpgqul6mz0b',
    center: [-76.615573, 39.285685],
    zoom: 16 // starting zoom
});

var geojson = {
    "type": "FeatureCollection",
    "features": [{
            "type": "Feature",
            "properties": {
                "title": "Shake Shack",
                "id": "shake-shack"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [-76.609844, 39.286894]
            }
        },
        {
            "type": "Feature",
            "properties": {
                "title": "Starbucks",
                "id": "starbucks"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [-76.619071, 39.286649]
            }
        }
    ]
};

我已将数据存储在JSON数组中:

I've stored the data in a JSON array:

[{"title":"Shake Shack","slug":"shake-shack","latitude":"-76.609844","longitude":"39.286894"},{"title":"Starbucks","slug":"starbucks","latitude":"-76.619071","longitude":"39.286649"}]

如何将其插入geoJSON?

How do I insert this into the geoJSON?

推荐答案

弄清楚了:

首先，我创建了一个插件，用于将自定义帖子数据存储在JSON数组中，并将其存储在服务器上.每当我更新，保存或删除帖子时，此信息也会更新.这是示例JSON:

First I created a plugin that stored the custom post data in a JSON array and stored it on the server. This also updated every time I updated, saved or deleted a post. Here is the example JSON:

data = {"placeList": [{"title":"Shake Shack","slug":"shake-shack","latitude":"-76.609844","longitude":"39.286894"},{"title":"Starbucks","slug":"starbucks","latitude":"-76.619071","longitude":"39.286649"}]}

然后在php文件中，我调用了.json文件，并在我的JavaScript中，将数组插入了GeoJSON:

Then in the php file, I called the .json file and in my javascript, inserted the array into the GeoJSON:

var placeJson = data;

        var geojson = {
          type: "FeatureCollection",
          features: [],
        };

        for (i = 0; i < placeJson.placeList.length; i++) {

          geojson.features.push({
            "type": "Feature",
            "geometry": {
              "type": "Point",
              "coordinates": [placeJson.placeList[i].latitude, placeJson.placeList[i].longitude]
            },
            "properties": {
              "id": placeJson.placeList[i].slug,
              "title": placeJson.placeList[i].title
            }
          });
        }
