PhoneGap文件删除不工作 [英] PhoneGap File Remove not working

问题描述

我正在建立一个基本的应用程序，具有PhoneGap相当大，因为我试图确定它可以/不能做。我已经到了舞台，我想要删除已经下载的应用程序，但它不会工作的文件。我使用的大部分代码来自 http：// docs .phonegap.com / en / 2.4.0 / cordova_file_file.md.html＃FileEntry ;

I am building up a basic app which features PhoneGap pretty heavily as i am trying to determine what it can/can't do. i have gotten to the stage where i am looking to remove a file that has been downloaded on the app, but it won't work. most of the code i've used is from http://docs.phonegap.com/en/2.4.0/cordova_file_file.md.html#FileEntry;

    function removefile(){
        fileSystem.root.getFile("readme.txt", {create: false, exclusive: false}, gotRemoveFileEntry, fail);

    }

    function gotRemoveFileEntry(fileEntry){
        console.log(fileEntry);
        fileEntry.file(gotFile, fail);
        entry.remove(success, fail);
    }

    function success(entry) {
        console.log("Removal succeeded");
    }

    function fail(error) {
        console.log("Error removing file: " + error.code);
    }

我使用HTML调用它;

and i have called it using the HTML;

    <button onclick="removefile();">remove file</button>

代码有什么问题吗？我不能看到它。

is there something wrong with the code? i can't see it.

顺便说一句，我编写的iOS，并使用JavaScript，HTML和Xcode中的PhoneGap / Cordova。

By the way I'm coding for iOS and using JavaScript, HTML and PhoneGap/Cordova in Xcode.

我是iPhone开发的新手，所以任何帮助将非常感谢很多：）

I'm fairly new to iPhone development so any help would be great thanks a lot :)

推荐答案

您的代码略有偏离。尝试：

Your code is slightly off. Try:

function removefile(){
    fileSystem.root.getFile("readme.txt", {create: false, exclusive: false}, gotRemoveFileEntry, fail);
}

function gotRemoveFileEntry(fileEntry){
    console.log(fileEntry);
    fileEntry.remove(success, fail);
}

function success(entry) {
    console.log("Removal succeeded");
}

function fail(error) {
    console.log("Error removing file: " + error.code);
}
