我正在嘗試使用PACKT發佈出版的「PhoneGap Mobile Application Development Cookbook」學習phonegap。第2章討論文件系統,這似乎給出了一些錯誤。我複製的示例代碼和我得到以下錯誤:Phonegap 2.4.0 - NetworkStatus警報
「NetworkStatusxxxxxxxxxx」](每次數量是不同的)。 我一直在尋找解決方案几個小時,但沒有成功,誰可以幫忙?!
我的代碼:
!DOCTYPE html>
文件下載
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 "";
}
