這篇文章主要講解了JS腳本實(shí)現(xiàn)定時(shí)到網(wǎng)站上簽到/簽退功能的方法,內(nèi)容清晰明了,對此有興趣的小伙伴可以學(xué)習(xí)一下,相信大家閱讀完之后會(huì)有幫助。

之前介紹過使用temperMonkey屏蔽CSDN廣告的方法,主要就是要針對性地分析網(wǎng)站結(jié)構(gòu),然后用代碼去改變或者操作DOM。今天也一樣,我們需要觀察網(wǎng)頁結(jié)構(gòu),找到我們要操作的按鈕,觸發(fā)他的
click
事件就可以了。下面以公司打卡簽到的網(wǎng)站為例,做一些壞壞的事情。本文讀者最好有一定的HTML和JavaScript基礎(chǔ)。
首先,想象一下你去簽到需要做什么:
然后每一步我們都可以讓代碼幫我們?nèi)プ觥?/p>
0. 如何定時(shí)
這段代碼是核心,就是根據(jù)當(dāng)前時(shí)間和設(shè)定的時(shí)間做差值,來確定定時(shí)器的值
看懂這段代碼,后面的就都容易了。都是在利用定時(shí)器觸發(fā)callback。
// user setting const SIGN_IN_TIME = "09:30:00"; // 簽到時(shí)間 const SIGN_OUT_TIME = "20:00:00"; // 簽退時(shí)間 // code implementation logTime("code start running"); const now = new Date(); const today = now.getFullYear() + "-" + (now.getMonth() + 1) + "-" + now.getDate(); var signInTime = +new Date(`${today} ${SIGN_IN_TIME}`); logTime("signInTime", new Date(signInTime)); var signOutTime = +new Date(`${today} ${SIGN_OUT_TIME}`); logTime("signOutTime", new Date(signOutTime)); // diff in or out if (now > signInTime && now < signOutTime) { // ready to sign out for today console.log("Seconds to sign out for today: " + (signOutTime - now) / 1000); setTimeout(callback, signOutTime - now); } else { // ready to sign in for tomorrow signInTime = +signInTime + 60 * 60 * 24 * 1000; console.log("Seconds to sign in for tomorrow: " + (signInTime - now) / 1000); setTimeout(callback, signInTime - now); } function logTime(str, time = new Date()) { console.log(`${str} -> ${time.getHours()}:${time.getMinutes()}:${time.getSeconds()}`); }
1. 定時(shí)自動(dòng)打開網(wǎng)站
因?yàn)榇蠖鄶?shù)網(wǎng)站都有,“長時(shí)間未操作-自動(dòng)退出”的設(shè)置。所以我們要在需要打卡的時(shí)候再打開網(wǎng)站。
在電腦本地跑一個(gè)程序,使用定時(shí)器。這里跑一個(gè)node程序:
const open = require('open'); logTime("Start Runing"); // user setting const SIGN_IN_TIME = "09:30:00"; const SIGN_OUT_TIME = "20:20:00"; // code implementation const openBrowser = async () => { await open('http://172.10.80.42'); }; logTime("code start running"); const now = new Date(); const today = now.getFullYear() + "-" + (now.getMonth() + 1) + "-" + now.getDate(); var signInTime = +new Date(`${today} ${SIGN_IN_TIME}`); logTime("signInTime", new Date(signInTime)); var signOutTime = +new Date(`${today} ${SIGN_OUT_TIME}`); logTime("signOutTime", new Date(signOutTime)); // diff in or out if (now > signInTime && now < signOutTime) { // ready to sign out for today console.log("Seconds to sign out for today: " + (signOutTime - now) / 1000); setTimeout(openBrowser, signOutTime - now); } else { // ready to sign in for tomorrow signInTime = +signInTime + 60 * 60 * 24 * 1000; console.log("Seconds to sign in for tomorrow: " + (signInTime - now) / 1000); setTimeout(openBrowser, signInTime - now); } function logTime(str, time = new Date()) { console.log(`${str} -> ${time.getHours()}:${time.getMinutes()}:${time.getSeconds()}`); }
2. 自動(dòng)登錄
這個(gè)重點(diǎn)還是在于找到需要填入內(nèi)容的DOM元素
(function() { 'use strict'; // login document.querySelector("#loginid").value = "用戶名"; document.querySelector("#userpassword").value = "密碼"; document.querySelector("#login").click(); })();
3. 定時(shí)點(diǎn)擊按鈕
這一步最重要的是要準(zhǔn)確找到按鈕,檢查元素慢慢查找吧。
其次,設(shè)定好簽到和簽退的時(shí)間,只有固定時(shí)間才會(huì)自動(dòng)簽到,防止每次登陸進(jìn)來自動(dòng)簽到或簽退,這樣太頻繁被發(fā)現(xiàn)。
(function() { 'use strict'; // user setting const SIGN_IN_TIME = "09:00:00"; const SIGN_OUT_TIME = "21:00:00"; // code implementation logTime("code start running"); const now = new Date(); const today = now.getFullYear()+"-"+(now.getMonth()+1)+"-"+now.getDate(); var signInTime = +new Date(`${today} ${SIGN_IN_TIME}`); logTime("signInTime", new Date(signInTime)); var signOutTime = +new Date(`${today} ${SIGN_OUT_TIME}`); logTime("signOutTime", new Date(signOutTime)); // diff in or out if(now > signInTime && now < signOutTime) { // ready to sign out for today console.log("Seconds to sign out for today: " + (signOutTime - now)/1000); setTimeout(signInorSignOut, signOutTime - now); } else { // ready to sign in for tomorrow signInTime = +signInTime + 60 * 60 * 24 * 1000; console.log("Seconds to sign in for tomorrow: " + (signInTime - now)/1000); setTimeout(signInorSignOut, signInTime - now); } // signInorSignOut function signInorSignOut(){ logTime(`signInButton clicked!`); // 重點(diǎn)就在這兒了,找到網(wǎng)站的簽到按鈕#signInButton,并觸發(fā)他的點(diǎn)擊事件 document.querySelector("#signInButton").click(); } function logTime(str, time=new Date()){ console.log(`${str} -> ${time.getHours()}:${time.getMinutes()}:${time.getSeconds()}`); } })();
4. 結(jié)束
一套操作,打完收工。每天下班的時(shí)候,不管是提前溜還是晚點(diǎn)到。記得本地開一下程序:
node timer.js
