WeChat Mini Programs local data reading example

In general, under Mini Program's utils folder, we can write local data in, package it into .js files, provide an interface for exposure, and then read local data. If some processing methods for this data are involved, you can also write the methods, encapsulate them in a .js file, and then call them when needed.

Module.exports = {mtData: mtData, searchmtdata: searchmtdata, usedraw: usedraw} var mt_data = mtData () function searchmtdata (id) {var result for (let I = 0; I < mt_data.list.length) Return result +) {var mt = mt_ data.list [I] if (mt.id = = id) {result = mt}} return result | | {}} function mtData () {var arr = {list: [{id: '1list, MTId:' MT001', status: 'working', Duration: 3, Operator:' tom' IdleReason: 'lunch'}, {id:' 2percent, MTId: 'MT002', status:' Idle', Duration: 7, Operator: 'jerry', IdleReason:' reparied'}, {id: '3percent, MTId:' MT003', status: 'Idle', Duration: 6 Operator: 'tom', IdleReason:' lunch'}, {id: '4percent, MTId:' MT004', status: 'working', Duration: 9, Operator:' jerry', IdleReason: 'reparied'}, {id:' 5percent, MTId: 'MT005', status:' Idle' Duration: 2, Operator: 'tom', IdleReason:' lunch'}, {id: '6percent, MTId:' MT006', status: 'working', Duration: 6, Operator:' jerry', IdleReason: 'reparied'}, {id:' 7percent, MTId: 'MT007' Status: 'Idle', Duration: 1, Operator:' tom', IdleReason: 'lunch'}]} return arr}

As shown in the code snippet above, the local data written by function mtData contains the object List. In addition, there is a function searchmtdata, which loads specific data according to the parameters passed. Next, after the method and data are written, you need to write an exposed API:

Module.exports = {mtData: mtData, searchmtdata: searchmtdata, usedraw: usedraw}

Call the data file on other pages (usually in the js file)

Var fileData = require ('.. /.. / utils/data.js') Page ({data: {showData: fileData.mtData () .list,},})

As in the example above, after a value is assigned in data {}, the showData can be displayed directly in wxml.
