Message:

I've used jquery to get an "id" as a value for an input according to a dropdown value. Now the problem is, I want to use the 'id' to insert value to some other inputs. I don't know which event method to be used. For testing, I used the keyup method to check if the code works, when I manually type in a number, it works. So the problem is with the event method I choose. Please give me some suggestions.

    //Get id

     $(document).ready(function() {

        $('#salary_eid').change(function() {

            var sid = $(this).val();

            var data_String = 'sid=' + sid;

            $.get('search1.php', data_String, function(result) {



                $.each(result, function(){

                  $('#can').val(this.c_id);

          

                    

                });

            });       

          });



      //display other information

      $('#can').change(function() {

            var id = $(this).val();

            var data_String1 = 'id=' + id;

            $.get('search.php', data_String1, function(result1) {



                $.each(result1, function(){

                  $('#morning_rate').val(this.cMorning);

                    $('#night_rate').val(this.cNight);

                    $('#ot_rate').val(this.clientOt);

                    

                });

            });

        });

    });



 <label>Name</label>

 <input type="text" name="salary_eid" />

 <select id="salary_eid">

  <option>opt1</option>

  <option>opt2</option>

 </select>

    

 <input type="hidden" name="can" id="can" class="form-control" >

My Answer:
input value using the `val()` method. Here's an example code snippet:

Get Value







In this code, we have an input field with the id `myInput` and a button with the id `getValueBtn`. When the button is clicked, we use the `val()` method to get the value of the input field and display it in an alert box.
