我在目录中保存了一些文件,但是现在需要在手机间隙中读取该文件。我试试这个,但我无法读取文件。 这是我的保存文件和读取文件代码?我没有得到任何读取数据?我也研究了phonegap文档,但无法阅读
function saveDataOnTextFile(){
try {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
function(fileSystem) {
fileSystem.root.getDirectory(CASENAME, { create: true, exclusive: false }, function(directoryEntry) {
console.log("log folder is created");
directoryEntry.getFile(DOCUMENT_NAME+".rtf", { create: true, exclusive: false }, function(fileEntry) {
fileEntry.createWriter(function(writer) {
writer.seek(writer.length);
writer.write($('#realTimeContents').text());
}, fail);
}, fail);
}, fail);
},
fail);
}
catch(e) {
fail(e+"fail");
}
}
function readRtfFile(){
try {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
function(fileSystem) {
fileSystem.root.getDirectory(CASENAME, { create: true, exclusive: false }, function(directoryEntry) {
console.log("log folder is created");
directoryEntry.getFile(DOCUMENT_NAME+".rtf", { create: true, exclusive: false }, function(fileEntry) {
fileEntry.createReader(function(reader) {
reader.readEntries(function(entries){
var i;
for (i=0; i<entries.length; i++) {
console.log(entries[i].name);
}
},fail);
}, fail);
}, fail);
}, fail);
},
fail);
}
catch(e) {
fail(e+"fail");
}
}
