Question

我是cordova和javascript的新手。我只是试图打印一些消息，并希望在我单击按钮时显示警报。但是一旦应用程序加载就会发生。

这是我的代码。

<body>
    <div class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
        </div>
           <button id = "setLocalStorage">SET LOCAL STORAGE</button>
            <br/>
        <button id = "showLocalStorage">SHOW LOCAL STORAGE</button><br/>
        <button id = "removeProjectFromLocalStorage">REMOVE PROJECT</button><br/>
        <button id = "getLocalStorageByKey">GET BY KEY</button>
        <p id="demo"></p>
    </div>
    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/index.js"></script>
    <script type="text/javascript" src="js/myscript.js"></script>
</body>

的Javascript

 document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage());
 function showLocalStorage() {
    document.getElementById("demo").innerHTML = "value is empty";
  console.log('fsdfsd');
  alert("am i amazing!!")
}

请指出我错误的地方。感谢。

Answer 1

不要执行该函数，只需将其绑定到addEventListener并在单击时执行它。

更改此

document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage());

到这个

document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage);

Cordova：onclick事件在按钮点击之前调用
