How to implement webpage grabbing red envelopes in Javascript

This article describes the principles and ideas of Javascript writing through an example of a web page for grabbing red envelopes. Interested friends can refer to it for reference.

At first, I used Firefox to add the Firebug/YSlow plug-in for analysis, but Firefox could not run custom javascript, and it seemed that I needed to install some plug-ins. So I switched to chrome and found that chrome is pretty good. You can just write javascript and install it as a plug-in.

Taobao also changed the script several times, but of course it was the same every time. I admire the hard-working Taobao programmers who have to work overtime on weekends to revise scripts.

The appendix is a version of the script I wrote. Directly calling

Volcano.BrickRate=1.0; Volcano.Brick.getLottery(KISSY);

KISSY is something similar to JQuery. It took me a long time to figure it out.

After hanging up for 2 days, I only won 50 yuan in total. It is said that the big prizes are all leaked, you know. If Taobao only distributes rewards based on accounts, plug-in scripts are useless, haha.

Second version of script.

// tmall scripts in Chrome // // // ==UserScript== // @name tmall // @namespace google // @author vesor // @description Simple userscript to grasp tmall lottery // @include http://www.tmall.com Volcano.BrickRate=1.0; Volcano.Brick.getLottery(KISSY); //var L = S.DOM.get("#J_Lucky"); //L.click(); if(++tryCount) setTimeout(loopWrapper, 100); } loopWrapper(); console.log("tmall.user.js: Loaded"); } } catch(e) { console.log("Failed loading tmall.user.js"); }

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
