Blackberry文件(Webworks)

Question

我正在尝试(非常简单地)使用webworks获取相机目录的文件列表。我正在尝试的代码如下：

function displayPhotos(id) {
try {
    var Dir, path, items;

    if ((window.blackberry === undefined) || (blackberry.io === undefined) || (blackberry.io.file === undefined)) {
        appendContent("photoDetails", "<p><i><b>blackberry.io.file</b> object not found (likely cause is WebWorks APIs are not supported by this user agent).</i></p>");
        debug.log("displayPhotos", "blackberry.io.file object is undefined.", debug.error);
        return false;
    }

    Dir = blackberry.io.dir;

    path = "";      
    path = "file:///Device/home/user/camera"";


    items = Dir.listFiles(path);

    console.log(items);

    //setContent(id, formatAsHTML(path, items));

}
catch(e) {
    console.log("displayPhotos", e, debug.exception);
}
}

所有我得到的是错误1004 -我假设这是基于权限的，但我不相信我不能在相机上读取失败-有人知道什么吗？

干杯!

好吧，我想出来了，希望这能帮助任何人得到可怕的黑莓webworks错误1004。

您需要在存储路径中更改设备。真的就是这样。此示例有效：

function displayPhotos(myFolder) {
    try {
        var Dir, path, items;       
        Dir = blackberry.io.dir;

    path = "";      
    if (myFolder != undefined){
        path = myFolder;
    } else {
        path = "file:///store/home/user/pictures";
        //file:///store/home/user/camera
    }

    items = Dir.listFiles(path);        
    return items;
}
catch(e) {
    console.log("displayPhotos", e, debug.exception);
}
}


function displayFiles(myFolder) {
try {
    console.log("displayFiles", "in " + myFolder);
    return displayPhotos(myFolder);
}
catch(e) {
    console.log("displayFiles", e, debug.exception);
}
}

你可以这样称呼它：

 displayFiles();

或者指定文件夹，如下所示：

 displayFiles("file:///store/home/user/camera");

返回文件名数组。

希望这对某些人有帮助！
