你好伙伴开发者， 我是PhoneGap的新手，未编码多年，并且在下面的addEventListener中遇到了问题。PhoneGap/Cordova v5 addEventListener不等待点击的点击事件
即使用户没有单击该按钮，该事件被调用并且显示警报，但我正在JavaScript中的addEventListener中抽样的警报始终显示。我想确保只在按钮被实际点击时显示警报。
任何帮助，你可以提供将是非常棒的。
干杯 德瑞
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
onDeviceReady: function() {
alert("PhoneGap is working in index.js onDeviceReady");
var buttonTwo = document.getElementById("btnPageTwo");
// the below event listener is fired always, even without the user clicking or performing any action the alert is displayed
buttonTwo.addEventListener('click', alert("Button Clicked"), false);
app.receivedEvent('deviceready');
},
// Update DOM on a Received Event
receivedEvent: function(id) {
var parentElement = document.getElementById(id);
var listeningElement = parentElement.querySelector('.listening');
var receivedElement = parentElement.querySelector('.received');
listeningElement.setAttribute('style', 'display:none;');
receivedElement.setAttribute('style', 'display:block;');
console.log('Received Event: ' + id);
