只要我将标签添加到我的jQuery select2，它就会中断并恢复为正常的HTML select框。
这是我的代码（与this example完全相同）：
$(document).ready(function() {
$("#tags").select2({tags:["red", "green", "blue"]});
});
如果我删除标签部分，它会再次起作用：
$(document).ready(function() {
$("#tags").select2();
});

如果查看javascript控制台，您将看到以下错误消息：
错误：选项＆＃39;标记＆＃39;当附加到a时，不允许使用Select2
<select>元素。
这意味着，当您想要使用＆＃39;标签＆＃39;选项，您必须将其应用于input:text元素而不是select。

Select2 version 4.0.0现在允许将标记附加到 public class ImageGetterAsyncTask extends AsyncTask<String, Void, Drawable> {
URLDrawable urlDrawable;
public ImageGetterAsyncTask(URLDrawable d) {
this.urlDrawable = d;
}
@Override
protected Drawable doInBackground(String... params) {
String source = params[0];
return fetchDrawable(source);
}
@Override
protected void onPostExecute(Drawable result) {
// set the correct bound according to the result from HTTP call
urlDrawable.setBounds(0, 0, 0 + result.getIntrinsicWidth(), 0
+ result.getIntrinsicHeight());
// change the reference of the current drawable to the result
// from the HTTP call
urlDrawable.drawable = result;
// redraw the image by invalidating the container
URLImageParser.this.container.invalidate();
}
/***
* Get the Drawable from URL
* @param urlString
* @return
*/
public Drawable fetchDrawable(String urlString) {
try {
InputStream is = fetch(urlString);
Drawable drawable = Drawable.createFromStream(is, "src");
drawable.setBounds(0, 0, 0 + drawable.getIntrinsicWidth(), 0
+ drawable.getIntrinsicHeight());
return drawable;
} catch (Exception e) {
return null;
}
}
private InputStream fetch(String urlString) throws MalformedURLException, IOException {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet(urlString);
HttpResponse response = httpClient.execute(request);
return response.getEntity().getContent();
}
}
