var Bmob = require('../../utils/bmob.js');var app = getApp();Page({ data: { longitude: "", latitude: "", markers: [], controls: [{ iconPath: '/images/address.png', position: { left: (app.globalData.windowWidth / 2) - 20, top: (app.globalData.windowHeight - 40) / 2 - 38, width: 40, height: 40 } }, { id: 1, iconPath: '/images/positioning.png', position: { left: 20, top: 20, width: 40, height: 40 }, clickable: true } ] }, staticData: {}, onShow() { this.getLocation(); }, onReady: function(e) { var that = this; this.mapCtx = wx.createMapContext('Map'); const query = Bmob.Query("customerInfo"); query.find().then(res => { console.log(res) for (var i = 0; i < res.length; i++) { that.setData({ markers: { id: i, iconPath: "/images/buy.png", latitude: res[i].latitude, longitude: res[i].longitude, width: 50, height: 50 } }) console.log(that.data.markers) } }); |
图片上是markers的值，但是为啥markers不显示
that.setData({markers: [{id: i,iconPath:"/images/buy.png",latitude: res[i].latitude,longitude: res[i].longitude,width: 50,height: 50}]})我知道应该这样写，但是我想在markers加入多个对象，所以用for循环生成多个对象
那你应该push
push是什么，求教，谢谢
let markers = []for(vari = 0; i < res.length; i++) {let marker = {id: i,iconPath:"/images/buy.png",latitude: res[i].latitude,longitude: res[i].longitude,width: 50,height: 50}markers.push(marker)
}that.setData({markers:markers})
谢谢，你等我试验一下
