我需要通过单击模态窗口上的Ajax按钮来执行文件上传。我有问题,因为文件已上传,但上传过程未完成,并且无法使用fileName更新表单。上传文件后无法隐藏AjaxIndicator。模态窗口实现为Panel。这是代码:
uploadFile=new IndicatingAjaxButton("uploadFile"){
private static final long serialVersionUID = 1L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
uploadFile.getAjaxIndicatorMarkupId();
FileUpload fileUpload =
((FileUploadFieldPanel)uploadPanel).getUploadField().getFileUpload();
if (fileUpload != null)
{
String fileName = fileUpload.getClientFileName();
String path = uploadpath + relativeuploadpath;
File newFile = new File(path, fileName);
checkFileExists(newFile);
try {
newFile.createNewFile();
fileUpload.writeTo(newFile);
}
catch (IOException e) {
e.printStackTrace();
}
titleField.setModelObject(fileName);
target.addComponent(titleField);
}
};
uploadFile.setOutputMarkupId(true);
form.add(uploadFile);
问题是:如何使用fileName更新表单上的titleField?在这种情况下,“target.addComponent(titleField);”不起作用。
