如何同时按下按钮和Enter键会导致同一事件？

Question

我是JavaScript的新手，所以请耐心等待。我正在做一个待办事项列表应用程序，该应用程序要求用户在文本框中输入文本，并且在单击按钮或输入密钥时将添加该项目。我可以使用Button Click执行此操作，当我添加Enter键的功能时，按钮停止工作。你能告诉我我做错了什么吗？下面是我的java脚本代码。谢谢。

//server.js
'use strict';

var koa = require('koa');
var app = koa();
var serve = require('koa-static');
var path = require('path');
var router = require('koa-router');
var cfg = require('./config');
var mw = require('./middleware');

app.use(serve(path.resolve(__dirname, '../client')));
app.use(mw.requestTime('Response-time'));
app.use(router(app));
app.use(cfg.db.connect);

require('./routes')(app);

app.get('/api', function *(){
  this.body = 'Welcome to API v1';
});

app.use(cfg.db.close);
app.listen(cfg.env.port);



//routes.js
module.exports = function (app){
  app.use(require('./api/things').routes());
};


// api/things/index.js
var Router = require('koa-router');

var router = new Router({
  prefix: '/api/things'
});

var ctrl = require('./controllers');

router.get('/', ctrl.list);
router.get('/:id', ctrl.get);
router.post('/', ctrl.post);
router.put('/:id', ctrl.put);
router.del('/:id', ctrl.del);

module.exports = router;


// api/things/controllers.js

var r = require('rethinkdb');
var http = require('http');
var parse = require('co-body');
var ctrl = module.exports = {};

ctrl.list = function *(next){
};

ctrl.get = function *(next){
};

ctrl.post = function *(next){
};

ctrl.put = function *(next){
};

ctrl.del = function *(next){
};
