Exports // const wsAPI = require(".. /.. /utils/wsAPI.js")Copy the codeExample:
wsAPI.taskSequence() .then(() => wsAPI.showLoading({title: "Save"})). Then (() = > wsAPI. Sleep (1000)), then (() = > wsAPI. HideLoading ()), then (() = > wsAPI. Sleep (500)). Then (() = > wsAPI.showLoading({title: "Load"})). Then (() = > wsAPI. Sleep (1000)), then (() = > wsAPI. HideLoading ()), then (() = > console. The log (" done "))Copy the codeFunction (A){B} =>{B}; WsAPI rewraps all of wX’s apis with Proxy (ECMAScript 6 Starter/Proxy). Sleep, Stop, and taskSequence have been added. Sleep is used to block a period of time; The taskSequence is an empty Promise that makes the code look neat and readable (Example 4). Stop is used to stop the task sequence
