This project is my usevueThe project is written on WeChat webpage. Now I want to ask WeChat’s location.apiThen I get the latitude and longitude parameters and then request the background interface to get the data. I write it in each component. Now I want to put this method into a common method, but I can call it and ask for the data first, but I can’t get the data in the component of the method, and the following is the code.Write in a separate onejsIn the document
//Location locationImport {getLocationUrl} from'common/config'Import {SaveLocalStorage, GetLocalStorage} from 'Common/localStorage'Import {PasswordPost} from'common/tool'Export function GetLocationPos () {Let _this=thisReturn wx.ready (function () {()Wx.getLocation ({Type:'wgs84The default is the GPS coordinates of WGS84. If we want to return the Mars coordinates directly to openLocation, we can import'gcj02'coordinates.Success: function (RES) {Let data=JSON.stringify (RES)SaveLocalStorage ('_User_Loaction_', data)Let str=res.latitude+','+res.longitudeReturn SendLocationAjax (STR)}})})}Function SendLocationAjax (params) {/ / access to detailed city informationReturn vm.$http.post (getLocationUrl, PasswordPost ({location:params})).Then ((RES) => {/ / console.log (res.data)Let data=JSON.stringify (res.data.data)Vm.$cookie.set ('user_location_info', data, {expires:'1h'}) / / save a 1 hour geographic cookie.Console.log (JSON.parsE (vm.$cookie.get ('user_location_info')))Return res.data})}Ask how to modify it to get data in the component.
In the component that you need this set of data, refer to your external JS file that gets the location.
import {GetLocationPos} from 'js File path 'Import {SendLocationAjax} from'js file path 'Next, you need to call these two methods in your life cycle to get the value of your return.
Pass a callback function in
GetLocationPosCan this function call directly to return the data?
wx.readyThe callback function function does not define the return return value, and it should be undefined.
