Question

我正在尝试从网址下载图片并且在ios中没有成功，但在android中它已成功完成。

var url = "http://www.intelligrape.com/images/logo.png"; // image url
try{
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {
        var imagePath = fs.root.fullPath + "/logo.png"; // full file path
        var fileTransfer = new FileTransfer();
        fileTransfer.download(url, imagePath, function (entry) {
            alert(entry.fullPath); // entry is fileEntry object
        }, function (error) {
            alert("Some error");
        });
    })
 }catch(e){
    alert(e);
 }

我收到错误LocalFileSystem未定义。我包括cordova2.5.0.js。

我的Config.xml在下面。

包括所有自定义js文件之前的cordova2.5.0.js文件。你可能会在你的代码之后加入它
