jQuery multiple autocomplete with different input IDs

问题

I use jQuery autocomplete and have multiple input fields with different IDs, and they are populated from a MySQL database.

  $("#CCU1").autocomplete({
  minLength : 1,
  source: function( request, response ) {
    $.ajax({
      url:"<?php echo site_url().'gsimc/autocomplete'; ?>",
      dataType: 'json',
      data: { 
        term  : $("#CCU1").val(),
        column: 'course',
        tbl   : 'tbl_courses'
      },
      success: function(data){
        if(data.response == 'true') {
          response(data.message);
        }
      }
    });
  }
});

The input fields has IDs of CCU1...CCU5, name='course'. Any idea how to autocomplete the five input fields instead of hardcoding each one?

Course1: <input type='text' name='course[]' id='CCU1'/><br />
Course2: <input type='text' name='course[]' id='CCU2'/><br />
Course3: <input type='text' name='course[]' id='CCU3'/><br />
Course4: <input type='text' name='course[]' id='CCU4'/><br />
Course5: <input type='text' name='course[]' id='CCU5'/><br />

Assuming that your above code is working for one of them, you could do:

$("[id^=CCU]").each(function(){
    $(this).autocomplete({
      minLength : 1,
      source: function( request, response ) {
        $.ajax({
          url:"<?php echo site_url().'gsimc/autocomplete'; ?>",
          dataType: 'json',
          data: { 
            term  : $(this).val(),
            column: 'course',
            tbl   : 'tbl_courses'
          },
          success: function(data){
            if(data.response == 'true') {
              response(data.message);
            }
          }
        });
      }
    });
});

Use `$(this)` instead of hardcoding the ID:

term: $("#CCU1").val(),

Replace it with:

term: $(this).val(),

Full code:

$("[id^=CCU]").each(function(){
    $(this).autocomplete({
      minLength : 1,
      source: function( request, response ) {
        $.ajax({
          url:"<?php echo site_url().'gsimc/autocomplete'; ?>",
          dataType: 'json',
          data: { 
            term  : $(this).val(),
            column: 'course',
            tbl   : 'tbl_courses'
          },
          success: function(data){
            if(data.response == 'true') {
              response(data.message);
            }
          }
        });
      }
    });
});
