Question

我需要将一个属性从我的组件传递给RouteData类。

@Component({
    selector: 'profile',
    templateUrl: 'profile.html',
})

@RouteConfig([
  {path:'/posts', name: 'ProfilePosts',   component: ProfileTracksComponent, data: {user}, useAsDefault: true}
])

export class ProfileComponent implements OnInit {
    user = {...}

我正在尝试将user属性放入RouteData（请参阅RouteConfig中的data属性），但angular2表示未定义用户。 this.user也不起作用。

我该怎么做？

您无法从应用于该类的装饰器中引用组件实例您可以使用共享服务注入Router并调用其中一个class CDealDataSent extends AsyncTask<String, Void, String> { public CDealAppDatastorage item; @Override protected void onPreExecute() { super.onPreExecute(); m_ProgressView.setVisibility(View.VISIBLE); } @Override protected String doInBackground(String... urls) { return DealListing(urls[0]);// sending data to server... } // onPostExecute displays the results of the AsyncTask. @SuppressWarnings("deprecation") @SuppressLint("SetTextI18n") @Override protected void onPostExecute(final String result) { m_ProgressView.setVisibility(View.GONE); try { m_oResponseobject = new JSONObject(result);// getting response from server JSONArray posts = m_oResponseobject.optJSONArray("dealList"); for (int i = 0; i < posts.length(); i++) { JSONObject post = posts.getJSONObject(i); item = new CDealAppDatastorage(); item.setM_szHeaderText(post.getString("dealname")); item.setM_szsubHeaderText(post.getString("dealcode")); item.setM_szDealValue(post.getString("dealvalue")); item.setM_n_Image(m_n_FormImage[i]); s_oDataset.add(item); } // LoadMore button Button btnLoadMore = new Button(getActivity()); btnLoadMore.setText("LOAD MORE DEALS"); btnLoadMore.setBackgroundResource(R.drawable.button_boarder); btnLoadMore.setTextAppearance(getActivity(), android.R.style.TextAppearance_DeviceDefault_Small); btnLoadMore.setTextColor(Color.WHITE); btnLoadMore.setGravity(Gravity.CENTER); if (!s_oDataset.isEmpty()) { // Adding Load More button to lisview at bottom m_ListView.addFooterView(btnLoadMore); m_oAdapter = new CDealAppListingAdapter(getActivity(), s_oDataset);// create adapter object and add arraylist to adapter m_ListView.setAdapter(m_oAdapter);//adding adapter to recyclerview m_oAdapter.notifyDataSetChanged(); } else { btnLoadMore.setVisibility(View.GONE); } btnLoadMore.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { m_n_DefaultRecordCount = m_n_DefaultRecordCount + 5;// increment of record count by 5 on next load data m_n_DeafalutLastCount = m_n_DeafalutLastCount + 5;// same here.....as above sz_RecordCount = String.valueOf(m_n_DefaultRecordCount);// convert int value to string sz_LastCount = String.valueOf(m_n_DeafalutLastCount);// convert int value to string ///// new DealNext().execute(m_DealListingURL);// POST DATA TO SERVER TO LOAD MORE DATA...... } }); getResponse(); } catch (JSONException e) { e.printStackTrace(); } } }函数来传递其他数据。
