我也是 iphone 和 phonegap 的新手。现在我想file使用phonegap在iphone中创建。我按照以下链接：

 "http://docs.phonegap.com/en/2.0.0/cordova_file_file.md.html#File"

在此链接中有一个带有 javascript 的 html 文件。所以我跟着编码。当我运行该编码时，我仅在 html 标记内容中得到输出。

I have attach that coding with my output.

    <script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Wait for Cordova to load
    //
    function onLoad() {
        document.addEventListener("deviceready", onDeviceReady, false);
    }

    // Cordova is ready
    //
    function onDeviceReady() {
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
    }

    function gotFS(fileSystem) {
        fileSystem.root.getFile("readme.txt", null, gotFileEntry, fail);
    }

    function gotFileEntry(fileEntry) {
        fileEntry.file(gotFile, fail);
    }

    function gotFile(file){
        readDataUrl(file);
        readAsText(file);
    }

    function readDataUrl(file) {
        var reader = new FileReader();
        reader.onloadend = function(evt) {
            console.log("Read as data URL");
            console.log(evt.target.result);
        };
        reader.readAsDataURL(file);
    }

    function readAsText(file) {
