PhoneGap的文件传输成功回调错误
我正在使用 PhonGap 的 FileTransfert 方法，如下所示
var options = new FileUploadOptions();
options.fileKey="file";
options.mimeType="image/jpeg";
//options.chunkedMode = true;
var params = new Object();
params.title = title;
params.content = content;
params.groupId = groupId;
options.params = params;
var ft = new FileTransfer();
app.loadmask.show();
ft.upload(app.imageURI, app.stores.actionAjaxURL + "&cmd=addActualite", this.onSuccessCreateActualite, this.onFailureCreateActualite, options, true);
这将转到成功回调函数，即：
onSuccessCreateActualite: function(response, options) {
/* REINIT FORM VALUES */
app.imageURI = null;
console.log("This log appears");
this.titleField.reset();
console.log("This log does not appear");
this.groupSelect.reset();
this.contentField.reset();
this.addBtn.resumeEvents();
this.picturePnl.update("No Picture");
app.stores.actualites.load();
app.loadmask.hide();
app.views.viewport.actualites.setActiveItem(
app.views.viewport.actualites.actualitesList, {type:'slide', direction:'right'}
);
app.views.viewport.actualites.actualitesList.actuGrid.scroller.scrollTo({ x: 0, y: 0 });
},
我收到此错误：
成功回调中的错误：com.phonegap.filetransfer1 = TypeError：“未定义”不是对象
有人知道为什么吗？
谢谢
I'm using PhonGap's FileTransfert method like so
var options = new FileUploadOptions();
options.fileKey="file";
options.mimeType="image/jpeg";
//options.chunkedMode = true;
var params = new Object();
params.title = title;
params.content = content;
params.groupId = groupId;
options.params = params;
var ft = new FileTransfer();
app.loadmask.show();
ft.upload(app.imageURI, app.stores.actionAjaxURL + "&cmd=addActualite", this.onSuccessCreateActualite, this.onFailureCreateActualite, options, true);
This goes to the success callback function which is :
onSuccessCreateActualite: function(response, options) {
/* REINIT FORM VALUES */
app.imageURI = null;
console.log("This log appears");
this.titleField.reset();
console.log("This log does not appear");
this.groupSelect.reset();
this.contentField.reset();
this.addBtn.resumeEvents();
this.picturePnl.update("No Picture");
app.stores.actualites.load();
app.loadmask.hide();
app.views.viewport.actualites.setActiveItem(
app.views.viewport.actualites.actualitesList, {type:'slide', direction:'right'}
);
app.views.viewport.actualites.actualitesList.actuGrid.scroller.scrollTo({ x: 0, y: 0 });
},
And I'm getting this error :
Error in success callback: com.phonegap.filetransfer1 = TypeError: 'undefined' is not an object
Does anyone knows why ?
Thanks

看起来“this.titleField”超出了 onSuccessCreateActualite 函数的范围。很可能“this”指的是与您想象的不同的对象。我会检查“this”的属性，看看它实际指的是什么。
It looks like "this.titleField" is out of scope in your onSuccessCreateActualite function. Most probably "this" is referring to a different object then you think it is. I'd inspect what the properties of "this" are to see what it actually refers to.
我的范围也有同样的问题。尝试像这样调用该函数：
在您的
upload()方法中。I had the same problem with my scope. Try calling the function like this:
in your
upload()method.
