实现vue引入maptalks地图及聚合效果的方法-创新互联

这篇文章给大家分享的是有关实现vue引入maptalks地图及聚合效果的方法的内容。小编觉得挺实用的，因此分享给大家做个参考。一起跟随小编过来看看吧。

1、安装maptalks.js

npm install maptalks --save

2、安装聚合mapkercluster

npm install maptalks.markercluster

3、vue页面引入

import * as maptalks from 'maptalks'

import {ClusterLayer} from 'maptalks.markercluster'

4、初始化地图并添加聚合

mounted() {
 let that = this
 //--0--//地图对象的初始化
 this.map = new maptalks.Map('map', {
  center: [109.1748453547,21.4586700546],
  //中心点标记红十字，用于开发debug
  centerCross : false,
  zoom: 13,
  minZoom : 10,
  maxZoom : 18,
  //缩放级别控件
  zoomControl : false, // add zoom control
  scaleControl : true, // add scale control
  //鹰眼控件
  overviewControl : true, // add overview control
  //设置瓦片图层的空间参考spatialReference默认就是3857，googlemap的分辨率
  spatialReference : {
   projection : 'EPSG:3857'
   //与map一样，支持更详细的设置resolutions，fullExtent等
  },
  baseLayer: new maptalks.TileLayer('base', {
   // urlTemplate: 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
   //renderer : 'canvas', // set TileLayer's renderer to canvas
   //底图服务器地址，如下为瓦片地址
   urlTemplate: 'http://xxx.xx.xxx.xxx:xxxx/mapdata/tiles/{z}/{x}/{y}.png',
   //tileSystem 控制瓦片的x,y以及行列，后两个是origin原点位置（很重要）
   tileSystem : [1, 1, -20037508.3427890,-20037508.3427890], // tile system
   //subdomains: ['a','b','c'],
   minZoom : 10,
   maxZoom : 18
   // css filter 滤镜配置
   // cssFilter : 'sepia(60%) invert(95%)',
   // attribution: '© Maptalk for Amap contributors'
  }),
  layers : [
   new maptalks.VectorLayer('v')
  ],
  attribution: {//左下角info
   content: '©qmap'
  }
 })
 
 // 拖动范围限制，黑框控
 let extent = new maptalks.Extent(108.8584570000,20.9790840000,110.0569128018,22.1177123207)
 // var extent = new maptalks.Extent(112.5381688894,26.8876543885,112.5605009244,26.9012691519);
 // set map's max extent to map's extent at zoom 14
 this.map.setMaxExtent(extent)
 this.map.setZoom(this.map.getZoom(), { animation : false })
 this.map.getLayer('v')
  .addGeometry(
   new maptalks.Polygon(extent.toArray(), {
    symbol : { 'polygonOpacity': 0, 'lineWidth': 0 }
   })
  )
 
// 往地图上添加点位
 
this.markInfo()
},
 
methods: {
 setCenter: function(center) {
  //标注点平移到某个点
  let centerV = maptalks1.CRSTransform.transform(center, 'bd09ll', 'gcj02')
  this.map.animateTo({
   zoom: 17,
   center: centerV
  }, {
   duration: 1000
  })
 },
 // 上图
 markInfo: function () {
  let that = this
  that.map.removeLayer(that.clusterLayer)
  let markers = []
  //--2--//前端聚合查询
  // data from realworld.50000.1.js
  //需要引入maptalks.markercluster.js
  //数据格式[lon,lat,name]
  // 如：[[21.8129763667, 109.2714296333, "晓港名城4号楼"],[21.8131727667, 109.2710308833, "晓港名城6号楼"]]
