我想將一個簡單的文本「你好」保存到使用phonegap filewriter API的文件中。我和一些書一起檢查了在線文檔(20個phonegap的食譜),但它仍然給我一個錯誤警報。下面是我的代碼:Phonegap javascript文件保存
function SavetoFile(name, surname, mobilenumber, email, language, addressline1, addressline2, locality){
var fileWriter;
saveFile();
function onLoad(){
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFSComplete, fail);
}
function onFSComplete(fileSystem){ // load file, create it if it doesn't exist
fileSystem.root.getFile("userdetails.txt", {create:true}. onFileEntryComplete, fail);
}
function onFileEntryComplete(fileEntry){ // set up a file writer
fileEntry.createWriter(onFileWriterComplete, fail);
}
function onFileWriterComplete(fileWriter){ // store the file writer in a global variable for when user presses save
fileWriter = fileWriter;
}
function saveFile(){
if(fileWriter != null){
fileWriter.onwrite = function(evt){
alert("Details Saved Successfully");
}
var fileline = "Hello";
fileWriter.write(fileline);
}
else{
alert("There was an error trying to save the file");
}
return false;
}
function fail(error) {
alert(error.code);
}
}
我打電話的主要功能的SaveToFile()和傳遞不同的參數。但是在使用它們之前,我想通過保存單詞「Hello」來進行較小規模的測試,因此我在主函數中調用另一種方法saveFile()。這仍然給我一個錯誤信息。任何想法問題的根源可能是什麼?
