我有带有ID的数组,并希望通过id删除它们

$membersId = array('1','2','3');
$inStatement = implode(',', $membersId);

//dont work!
TRatingMembers::model()->deleteAll(array('member_id IN (:member_id)'),
    array(':member_id' => $inStatement));

如何用一个事务删除所有行？

我有一个像这样的选项对话框:

String[]  options = ["Yes", "No"]; //button names

int n = JOptionPane.showOptionDialog(singleFrameService.getFrame(),
        "Some Question?",
        "",
        JOptionPane.YES_NO_OPTION,
        JOptionPane.QUESTION_MESSAGE,
        null,     //do not use a custom Icon
        options,  //the titles of buttons
        options[0]); //default button title

//if press yes
if (n == JOptionPane.YES_OPTION){
    //make some if pressed Yes
}

当我使用鼠标并按是/否 - 一切正常...但是当我开始使用键盘时,按TAB转到"否"按钮,然后按ENTER键 - 工作"是"选项

我有这样的代码

$(document).ready(function(){
     $(".add").bind ('click',
        function ()
        {
            $('.main').append('<div class="add">Add element 2</div>');
        });
    });
</script>

<div class="main"><div class="add">Add element</div></div>

当虚拟对象".add"附加到".main"时,jquery不会对它们进行单击作出反应

我有一个扩展ListActivity的类,它的工作正常

然后在onListItemClick()中我使用getSelectedItemPosition()并且它总是返回-1

PS getSelectedItemId()返回一些长号,如994393434

public class TasksShowActivity  extends ListActivity {

    private Cursor mCursor; 
    private ListAdapter mAdapter;

    private static final String[] mContent = new String[] {
        TasksDbHelper._ID, TasksDbHelper.NAME,
        TasksDbHelper.USER};

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);     

        mCursor = managedQuery(
                TasksProvider.CONTENT_URI, mContent, null, null, null);

        mAdapter = new SimpleCursorAdapter(this, 
                    R.layout.tasks, mCursor, 
                    new String[] {TasksDbHelper.NAME, TasksDbHelper.USER}, 
                    new int[] {R.id.name, R.id.date});

        setListAdapter(mAdapter);
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, final long id) {
        super.onListItemClick(l, v, position, id);

      Toast toast = Toast.makeText(this, "Position: …
