我已经使用 PhoneGap + Sencha Touch 2 创建了一个本机 android 应用程序。我已成功将文件上传到服务器,但是,我在 FileTransfer upload() 方法中从上传成功回调函数访问视图时遇到问题。这是我的代码:
上传回调:
uploadPicture: function(imageURI) {
var options = new FileUploadOptions(),
params = new Object(),
fileTransfer = new FileTransfer(),
builder = this.getBuilder(),
app = this.getApplication(),
uri = encodeURI('/myservlet');
options.fileKey = 'file';
options.fileName = imageURI.substr(imageURI.lastIndexOf('/') + 1);
options.mimeType = 'image/jpeg';
params.myparams = something;
params.moreparams = evenmore;
options.params = params;
options.chunkedMode = false;
fileTransfer.upload(imageURI, uri, this.uploadSuccess.bind(this), this.uploadError.bind(this), options);
},
上传成功函数
uploadSuccess: function (r) {
var builderChild = this.getBuilderChild(),
data = r.response.attachment;
builderChild.addInstance(builderChild.config, data);
navigator.notification.alert('Attachment successful.');
}
当我进入 uploadSuccess 函数时,我的 builderChild 对象未定义。我已经能够通过同一个控制器在其他功能中使用builderChild对象,但在uploadSuccess中不行。
有任何想法吗?
