javascript - How to change a dropdown into a table format? -


i have fetch data through ajax database in dropdown format.

now want change dropdown list table. beginner ajax... have done many of efforts, convert table looking difficult task me.

below complete code.

<script type="text/javascript"> function select_std(){   var ali=$('#class_std').val();   $('#std_name').html('');   $.ajax({     url:"<?php echo base_url().'admin/test/'?>"+ali,     type:"get",     success:function(res){       $('#std_name').append(res);     }   }); }  </script>

this controller

public function test($id=''){   $table='students';   $columns=array('*');   $where=array('c_id'=>$id);   $data['rcd']= $this->crud->get_records($table, $columns, $where)->result();    foreach ($data['rcd'] $value) {     $output = "<option value='".$value->std_id."'>".$value->name."</option>";     echo $output;   } } 


<div class="col-sm-2">   <select id="class_std" name="c_id" class="form-control selectboxit" onchange="select_std()">      <?php      $classes = $this->db->get('classes')->result_array();     foreach($classes $row):     ?>     <option value="<?php echo $row['c_id'];?>">       <?php echo $row['c_name'];?>     </option>     <?php     endforeach;     ?>   </select> </div>

here database displaying

<div class="col-md-6">   <select id="std_name" class="form-control">    </select> </div>

i agree complaints above, despite shortcomings in question, see if rocks boat:

/* js */  function select_std(){    var ali=$('#class_std').val();    $.ajax({      url:"<?php echo base_url().'admin/test/'?>"+ali,      type:"get",      success:function(res){        $('#mytable tbody').append(res);      }    });  }
<?php  /* controller - replace old 1 one */  public function test($id=''){    $table='students';    $columns=array('*');    $where=array('c_id'=>$id);    $data['rcd']= $this->crud->get_records($table, $columns, $where)->result();      foreach ($data['rcd'] $value) {      $output = "<tr><td>".$value->std_id."</td><td>".$value->name."</td></tr>";      echo $output;    }  }  ?>  <div class="col-sm-2">    <select id="class_std" name="c_id" class="form-control selectboxit" onchange="select_std()">        <?php       $classes = $this->db->get('classes')->result_array();      foreach($classes $row):      ?>      <option value="<?php echo $row['c_id'];?>">        <?php echo $row['c_name'];?>      </option>      <?php      endforeach;      ?>    </select>  </div>  <div class="col-md-6">        <table id="mytable">            <thead>                <th>student id</th>                <th>name</th>            </thead>            <tbody>                            </tbody>        </table>  </div>

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
