我正在尝试使用PACKT发布出版的“PhoneGap Mobile Application Development Cookbook”学习phonegap。第2章讨论文件系统,这似乎给出了一些错误。我复制的示例代码和我得到以下错误:Phonegap 2.4.0 - NetworkStatus警报
“NetworkStatusxxxxxxxxxx”](每次数量是不同的)。 我一直在寻找解决方案几个小时,但没有成功,谁可以帮忙?!
我的代码:
!DOCTYPE html>
文件下载
var downloadDirectory;
document.addEventListener("deviceready", onDeviceReady, true);
function onDeviceReady() {
window.requestFileSystem(
LocalFileSystem.PERSISTENT,
0,
onFileSystemSuccess,
null
);
x$('#download_btn').on('click', function(e) {
download();
});
}
function onFileSystemSuccess(fileSystem) {
fileSystem.root.getDirectory('my_downloads',{create:true},
function(dir) {
downloadDirectory = dir;
},fail);
}
function fail(error) {
x$('#message').html('We encountered a problem: ' + error.code);
}
function download() {
var fileURL = document.getElementById('file_url').value;
var localFileName = getFilename(fileURL);
x$('#message').html('Downloading ' + localFileName);
var fileTransfer = new FileTransfer();
fileTransfer.download(fileURL, downloadDirectory.fullPath + '/' + localFileName,
function(entry){
x$('#message').html('Download complete. File saved to: ' + entry.fullPath);
},
function(error){
alert("Download error source " + error.source);
}
);
}
// Obtain the filename
function getFilename(url) {
if (url) {
var m = url.toString().match(/.*\/(.+?)\./);
if (m && m.length > 1) {
return m[1] + '.' + url.split('.').pop();
}
}
return "";
}
