> npm install @turf/random
Returns a random position within a box. 接收一个边界框范围,返回在改边界框内随机的经纬度坐标
参数
返回
Position - Position longitude, latitude
Position - 经纬度坐标
示例
var position = turf.randomPosition([-180, -90, 180, 90]); // [lng, lat]
基础用法
<template> <base-map :center="coordinate ? coordinate : [120, 28]" :zoom="1"> <a-button type="primary" @click=" () => { visible = true; } " >打开</a-button > <drawer :visible.sync="visible" :code="code"> <template> <a-row> <a-space><bbox :value.sync="bbox"></bbox></a-space ></a-row> <a-row> <a-button type="primary" @click="handleSure">确定</a-button> </a-row> <a-row> <a-space>{{ coordinate }}</a-space> </a-row> </template> </drawer> <vue2ol-layer-vector :zIndex="20"> <vue2ol-source-vector> <vue2ol-feature v-if="coordinate"> <vue2ol-geom-point :coordinates="coordinate"></vue2ol-geom-point> </vue2ol-feature> </vue2ol-source-vector> </vue2ol-layer-vector> </base-map> </template> <script> import { Feature } from "ol"; import { LineString } from "ol/geom"; import * as turf from "@turf/turf"; export default { data() { return { coordinate: null, visible: true, result: null, bbox: [-180, -90, 180, 90], }; }, computed: { code() { return `let position = turf.randomPosition(${JSON.stringify(this.bbox)});`; }, }, mounted() {}, methods: { handleSure() { this.coordinate = turf.randomPosition(this.bbox); }, }, }; </script>
