akira-cn / handlock Goto Github PK

月影老师您好，最近在跟这个项目，代码中有一处不是很理解：

 if(this.mode !== Locker.MODE_UPDATE){
      await this.cancel();
      this.mode = Locker.MODE_UPDATE;
    }

在update和check方法中都先进行了判断，然后再 this.cancel();,这里 this.cancel();的作用是什么呢？我把这里注释掉以后，第一次设置密码可以成功，但是之后再次设置密码就会提示，设置的点不足四个。还请老师指点一下，谢谢！

npm start

[email protected] start G:\chromeDownload\handlock-master
webpack-dev-server --quiet & http-server example -c-1 -p 8081

Project is running at http://localhost:8080/
webpack output is served from /js/
(node:12212) DeprecationWarning: loaderUtils.parseQuery() received a non-string value which can be problematic, see webpack/loader-utils#56
parseQuery() will be replaced with getOptions() in the next major version of loader-utils.

npm start以后在浏览器访问http://localhost:8080/什么都没有
