路線規(guī)劃

簡(jiǎn)介

路線規(guī)劃常用于出行路線的提前預(yù)覽,我們提供4種類(lèi)型的路線規(guī)劃,分別為:駕車(chē)、步行、公交和騎行,滿足各種的出行場(chǎng)景。
高德開(kāi)放平臺(tái)

本例是駕車(chē)路線規(guī)劃功能和位置選擇地圖api:chooseLocation

示例:

1、在頁(yè)面的 js 文件中,實(shí)例化 AMapWX 對(duì)象,請(qǐng)求進(jìn)行駕車(chē)路線規(guī)劃。

首先,引入 amap-wx.js 文件(amap-wx.js 從相關(guān)下載頁(yè)面下載的 zip 文件解壓后得到)。

import amapFile from "@/libs/amap-wx.js";

然后在 onLoad 實(shí)例化 AMapWX 對(duì)象

onLoad() {
	 this.myAmapFunT = new amapFile.AMapWX({
		key: 你申請(qǐng)的key
	 })
	},

最后生成請(qǐng)求進(jìn)行駕車(chē)路線規(guī)劃數(shù)據(jù)
