wex5 file檔案儲存
在js中需要引入file的cordova包
require("cordova!cordova-plugin-file");
如果要存到手機的根目錄下，在Native資料夾的對應專案中的config.xml配置檔案裡新增
<preference name="AndroidPersistentFileLocation" value="Compatibility"/>
參考文件：http://docs.wex5.com/cordova-plugin-file/
建立檔案：
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {
console.log('file system open: ' + fs.name);
fs.root.getFile("newPersistentFile.txt", { create: true, exclusive: false }, function (fileEntry) {
console.log("fileEntry is file?" + fileEntry.isFile.toString());
// fileEntry.name == 'someFile.txt'
// fileEntry.fullPath == '/someFile.txt'
writeFile(fileEntry, null);
}, onErrorCreateFile);
}, onErrorLoadFs);
寫入檔案
function writeFile(fileEntry, dataObj) {
// Create a FileWriter object for our FileEntry (log.txt).
fileEntry.createWriter(function (fileWriter) {
fileWriter.onwriteend = function() {
console.log("Successful file read...");
readFile(fileEntry);
};
fileWriter.onerror = function (e) {
console.log("Failed file read: " + e.toString());
};
// If data object is not passed in,
// create a new Blob instead.
if (!dataObj) {
dataObj = new Blob(['some file data'], { type: 'text/plain' });
}
fileWriter.write(dataObj);
});
}
讀取檔案
function readFile(fileEntry) {
fileEntry.file(function (file) {
var reader = new FileReader();
reader.onloadend = function() {
console.log("Successful file read: " + this.result);
displayFileData(fileEntry.fullPath + ": " + this.result);
};
reader.readAsText(file);
}, onErrorReadFile);
}
