我试过读/写
文件中的 PhoneGap的+安卓
,这里是设置了:
I tried writing/reading
a file in phonegap+android
, here is the set up:
$(document).ready(function() {
document.addEventListener("deviceready", deviceready, true);
$(document).bind("deviceready", function(){
//writeFile();
//readFile();
});
});
function deviceready() {
writeFile();
readFile();
}
// This is just to do this.
function readFile() {
var d = navigator.file.read('/sdcard/foo.xml', success(), fail());
console.warn(d);
}
function writeFile() {
navigator.file.write('/sdcard/foo.xml', "This is a test of writing to a file",
success(), fail());
}
但在模拟器的Android 2.2 ,我得到了以下错误消息:
But on the emulator for Android 2.2, I got the following error message:
08-06 14:21:29.428: INFO/Web Console(936): Error in success callback: Network Status1 = TypeError: Result of expression 'navigator.file' [undefined] is not an object. at file:///android_asset/www/phonegap.0.9.6.js:649
还有什么人失踪,有什么可以尝试?
What could be missing and what could be tried?
对我来说,下面的工作在Android与PhoneGap的-1.0.0:
The following works for me on Android with phonegap-1.0.0:
<script type="text/javascript" charset="utf-8" src="css-js/phonegap-1.0.0.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
//
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function gotFS(fileSystem) {
var path = "readme.txt";
fileSystem.root.getFile(path, {create: true, exclusive: false}, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
fileEntry.createWriter(gotFileWriter, fail);
}
function gotFileWriter(writer) {
writer.onwrite = function(evt) {
console.log("write success");
};
writer.write("some sample text");
</script>
