我正在使用HTML5，JavaScript和IDE（eclipse）构建混合Android应用程序。
在我的应用中，我制作了两个html页面。一个是index.html，另一个是camera.html。
[index.html的]
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css" />
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<script type="text/javascript" src="js/index.js"></script>
<script type="text/javascript" src="cordova.js"></script>
</head>
<body>
<div data-role="page" id="index" style="width:100%; height:100%">
<div data-role="header">
<h1 class="title">Read Database</h1>
</div>
<div data-role="content">
<ul data-role="listview" data-inset="true" id="result"></ul>
</div>
<div data-role="footer">
<a href="insert.html" data-role="button" >Insert Data</a>
<a href="camera.html" data-role="button" >Camera/a>
</div>
</div>
</body>
</html>
[camera.html]
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<script>
var pictureSource;
var destinationType;
document.addEventListener("deviceready",onDeviceReady,false);
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
function onPhotoDataSuccess(imageData) {
var smallImage = document.getElementById('smallImage');
smallImage.style.display = 'block';
smallImage.src = "data:image/jpeg;base64," + imageData;
}
function onPhotoURISuccess(imageURI) {
var largeImage = document.getElementById('largeImage');
largeImage.style.display = 'block';
largeImage.src = imageURI;
}
function capturePhoto() {
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
correctOrientation : true,
destinationType: destinationType.DATA_URL });
}
function capturePhotoEdit() {
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20,
allowEdit: true, //android에서는 특별한 효과 없음, 무시됨
correctOrientation : true,
destinationType: destinationType.DATA_URL });
}
function getPhoto(source) {
navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,
correctOrientation : true,
destinationType: destinationType.FILE_URI,
sourceType: source });
}
function onFail(message) {
alert('Failed because: ' + message);
}
</script>
</head>
<body>
<div data-role="page" id="camera" style="width:100%; height:100%">
<div data-role="header">
<h1 class="title">Camera</h1>
</div>
<div data-role="content">
<img style="display:none; wdith:100%; height:100%" id="largeImage" src=""/>
</div>
<div data-role="footer">
<a href="index.html" data-role="button" >Main</a>
<button onclick="capturePhoto();">Capture Photo</button> <br>
<button onclick="capturePhotoEdit();">Capture Editable Photo</button> <br>
<button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">From Photo Library</button><br>
<button onclick="getPhoto(pictureSource.SAVEDPHOTOALBUM);">From Photo Album</button><br>
<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />
</div>
</div>
</body>
</html>
如果在这些代码中看到，我使用A标签按钮将index.html连接到camera.html。
当我按下并移动此按钮时，JavaScript无效。
从index.html页面移动到另一个页面时，除了index.html中的JavaScript代码外，它无法正常工作。
这张照片是我在混合应用程序中按下按钮的结果。
我该如何解决这个问题？
