后台返回查询企业数据，需要在左侧百度地图上进行企业打点，鼠标浮动展示企业名称。因为已经完成企业数据根据距离封装和列表展示，所以在此基础上循环数据，实现：
1、在地图上进行打点
2、以中心点分别在20、50、100、100外画圆
3、鼠标浮动显示企业名称
首先引入百度地图：新增map.js，代码如下：
export function MP(ak) {
return new Promise(function (resolve, reject) {
window.onload = function () {
resolve(BMap)
}
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://api.map.baidu.com/api?v=2.0&ak="+ak+"&callback=init";
script.onerror = reject;
document.head.appendChild(script);
})
}
在文件中添加：
import {MP} from '@/api/map.js'
let map = null,
geoc = null;
export default {
name: 'TestBaiDu',
data() {
return {
ak:'你的AK',
}
};
mounted(){
this.$nextTick(() => {
const _this = this
MP(_this.ak).then(BMap => {
_this.mapBuild()
})
})
},
created() {
this.mapBuild()
},
methods: {
mapBuild() {
let that = this;
this.dialogMap = !this.dialogMap;
setTimeout(function() {
if (that.mapGetshow) {
map = new BMap.Map("container");
geoc = new BMap.Geocoder();
let point = new BMap.Point(116.46, 39.92);
map.centerAndZoom(point, 10);
map.enableScrollWheelZoom();
var scaleCtrl = new BMap.ScaleControl(); // 添加比例尺控件
map.addControl(scaleCtrl);
// var zoomCtrl = new BMap.ZoomControl(); // 添加比例尺控件
// map.addControl(zoomCtrl);
var geolocation = new BMap.Geolocation();
//定位
geolocation.getCurrentPosition(
r => {
console.log(r);
var mk = new BMap.Marker(r.point);
map.addOverlay(mk);
map.panTo(r.point);
geoc.getLocation(r.point, function(rs) {
var addComp = rs.addressComponents;
console.log(addComp);
that.mapPointName =
addComp.province +
addComp.city +
addComp.district +
addComp.street +
addComp.streetNumber;
that.loading = false;
that.mapGetshow = false;
});
},
{ enableHighAccuracy: true }
);
//鼠标点击
map.addEventListener("click", function(e) {console.log(that.listQuery)
//必选条件都选择选项后传参
// if(that.listQuery.incident == "" ||that.listQuery.large == "" ||that.listQuery.medium == "" ||that.listQuery.small == "" ){
// alert("请选择查询条件！")
// }else{
console.log(e);
var pt = e.point;
var marker = new BMap.Marker(pt); // 创建标注
map.clearOverlays();
map.addOverlay(marker);
// 绘制圆
var circle = new BMap.Circle(e.point, 20000, { //半径为20公里圆
strokeColor: "blue",
