Question

我有一个数据表，我想检查是否所有的单选按钮都被选中，但这只适用于第一个分页页面，但无法检查其他页面

这是我的代码：

var dt =  $('#newtable').DataTable({
          "paging": true,
          "lengthChange": false,
          "searching": false,
          "ordering": true,
          "info": true,
          "autoWidth": false
        });

这是用于检查的内容

 $("input:radio").change(function() {
   var all_answered = true;
   dt.rows().nodes().each(function() {
      if($(":radio:checked").length == 0)
      {
        all_answered = false;
      }

   })


  if(all_answered==true ){
      $('input[type=text]#general_comment').removeAttr("disabled");
      approvebtn.removeAttr("disabled");

  }else {
      approvebtn.prop("disabled", "disabled");
  }
});

初始化数据表后，您可以在bind上page DataTable $('#newtable').bind('page', function () { //call to check what you want. });事件，分页（页面更改）将检查您想要的内容。

public void listeningForMessages() {
        PacketFilter filter = new AndFilter(new PacketTypeFilter(Message.class));
        PacketCollector collector = mConnection.createPacketCollector(filter);
while (true) {
        Packet packet = collector.nextResult();


        if (packet instanceof Presence) {
            Presence newPresence = (Presence) packet;
            String fromPresence = newPresence.getFrom();
            String contactJidPresence = "";
            if (fromPresence.contains("/")) {
                contactJidPresence = fromPresence.split("/")[0];
                Log.d(TAG, "The real jid is :" + contactJidPresence);
            } else {
                contactJidPresence = fromPresence;
            }
            if (newPresence != null) {
                System.out.println("Received availability update from "
                        + contactJidPresence + " : "
                        + (newPresence != null ? (packet) : "NULL"));
                Handler handler1 = new Handler(Looper.getMainLooper());
                toastThis = contactJidPresence;
                handler1.post(new Runnable() {

                    @Override
                    public void run() {
                        //Your UI code here
                        if (!ChatActivity.active) {
                            Toast.makeText(mApplicationContext, " You received a  presence from " + toastThis, Toast.LENGTH_LONG).show();
                        }
                    }
                });
            }
        }
//Rest of the logic
}
}

检查是否在jquery数据表中检查了所有单选按钮
