目前我正在下载模块.用户单击下载按钮后,将从服务器下载文件(pdf,zip文件或docx),并将其存储在本地存储中.我可以使用FileTransfer.Download()方法下载文件,但我无法通过传递文件路径打开它.
以下是我的代码:
<!DOCTYPE HTML>

<head>
<meta name = "viewport" content = "user-scalable=no,width=device-width" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8">

<style type="text/css">

}
</style>
<script type="text/javascript" charset="utf-8">
function init() {
document.addEventListener("deviceready", ready, true);
}
function ready() {
console.log("App is ready.");
}
function download() {
// var remoteFile = "https://dl.dropbox.com/u/6731723/a.zip";
var remoteFile = "https://dl.dropbox.com/u/6731723/Beaver.pdf";
var localFileName = remoteFile.substring(remoteFile.lastIndexOf('/') + 1);
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) {
fileSystem.root.getFile(localFileName, { create: true, exclusive: false }, function (fileEntry) {
var localPath = fileEntry.fullPath;
console.log("localPath1:" + localPath);
if (device.platform === "Android" && localPath.indexOf("file://") === 0) {
localPath = localPath.substring(7);
}
console.log("localPath2 save:" + localPath);
var ft = new FileTransfer();
ft.download(remoteFile,
localPath, function (entry) {
console.log("file path:" + entry.fullPath);
var linkopen = document.getElementById("openlink");
linkopen.style.display = "block";
linkopen.href = entry.fullPath;
// var dwnldImg = document.getElementById("dwnldImg");
//dwnldImg.src = entry.fullPath;
//dwnldImg.style.visibility = "visible";
//dwnldImg.style.display = "block";
}, fail);
}, fail);
}, fail);
}
function fail(error) {
console.log("error:" + error.code);
}
</script>
</head>
<body onload="init();">
<a href="#" onclick="download();">Download file</a>
<br />

<a href="#" id="openlink" style="display:none;font-size:larger;">open</a>

任何想法如何让它工作？
PhoneGap 本身不允许将 pdf 文件下载到您的 SD 卡上，并且不会自动显示 PDF 文件。
步骤2和3的详细信息：在Eclipse中
设置开发环境 PhoneGap 。从此处
下载示例的 java 类
将下载的文件解压到文件夹“ src ”中 从此处
下载示例中的 javascript
将下载的文件解压到文件夹“ assets /www”
中的 Index html 文件中。调用js：
<script charset="utf-8" src="main.js"> </script>
<script charset="utf-8" src="pdfviewer.js"> </script>
<script charset="utf-8" src="downloader.js"> </script>在“ res/xml/plugins.xml ”中添加：
<plugin name="Downloader" value="com.phonegap.plugins.downloader.Downloader"/>
<plugin name="PdfViewer" value="com.phonegap.plugins.pdfViewer.PdfViewer"/>要调用插件中定义的方法，请在index.html中测试以下代码：
<! DOCTYPE HTML>
<html>
<head>
<title> PhoneGap-Android PDF Opening App</title>
<script charset="utf-8" src="phonegap-1.0.0.js"></script>
<script charset="utf-8" src="main.js"></script>
<script charset="utf-8" src="pdfviewer.js"></script>
<script charset="utf-8" src="downloader.js"></script>
</Head>
<body>
<h1> Hello World </ h1>
<a href = "#" 'sampleurf.pdf', true, downloadOkCallbak, downloadErCallbak) "> Download pdf </a> <br>
<a href="#" onclick="window.plugins.pdfViewer.showPdf('/sdcard/download/sample/samplesurf.pdf');"> open </a>
</body>
