-

i have form collects information user. form composed of 10 input text field. individual value of input text field accessed via var first_name = $("#fname").val() example , passed var postdata = {'fname':first_name}; , passed ajax url: "<?php echo base_url(); ?>main_controller/save_data", data: postdata controller function again collect it. if have 30 input text field , used way, take me lot of time. best way pass numerous input field values using javascript in miniature way? there shortcut this? lot. have sample code below.

views:

<input class="input input-large" type="text" name="fname" id="fname" value=""/> <input class="input input-large" type="text" name="lname" id="lname" value=""/> <input class="input input-large" type="text" name="address" id="address" value=""/> <input class="input input-large" type="text" name="age" id="age" value=""/> <input class="input input-large" type="text" name="height" id="height" value=""/> <input class="input input-large" type="text" name="gender" id="gender" value=""/> <input class="input input-large" type="text" name="school" id="school" value=""/> <input class="input input-large" type="text" name="course" id="course" value=""/> <input class="input input-large" type="text" name="year" id="year" value=""/> <input class="input input-large" type="text" name="date_of_birth" id="date_of_birth" value=""/>  <button class="btn btn-success" id="save" name="save">save</button>  <script type="text/javascript"> $("#save").click(function(){     var fname = $("#fname").val();     var lname = $("#lname").val();     var address = $("#address").val();     var age = $("#age").val();     var height = $("#height").val();     var gender = $("#gender").val();     var school = $("#school").val();     var course = $("#course").val();     var year = $("#year").val();     var date_of_birth = $("#date_of_birth").val();      var postdata = {             'fname': fname,             'lname': lname,             'address': address,             'age': age,             'height': height,             'gender': gender,             'school': school,             'course': course,             'year': year,             'date_of_birth': date_of_birth     };      $.ajax({         type: "post",         url: "<?php echo base_url(); ?>main_controller/save_data",         data: postdata,         success: function (data) {             if (data.notify) {                 alert('success');             } else {                 alert('failed');             }         }     });      }); </script>

controller:

function save_data(){     $fname = $this->input->post('fname');     $lname = $this->input->post('lname');     $address = $this->input->post('address');     $age = $this->input->post('age');     $height = $this->input->post('height');     $gender = $this->input->post('gender');     $school = $this->input->post('school');     $course = $this->input->post('course');     $year = $this->input->post('year');     $date_of_birth = $this->input->post('date_of_birth');     $this->insert_model->save_data($fname,$lname,$address,$age,$height,$gender,$school,$course,$year,$date_of_birth);  }

indeed there is:

$("#save").click(function () {      var postdata = $("#idofyourform").serialize();      $.ajax({         type: "post",         url: "<?php echo base_url(); ?>main_controller/save_data",         data: postdata,          // perhaps better specify datatype         // of data expected server          // readability         datatype: 'json',         success: function (data) {             if (data.notify) {                 alert('success');             } else {                 alert('failed');             }         }     });      // maybe need     return false; });
