php - Fill textarea with database value from selected option -

i have select element has values of sequences in database:

<option value="1">one</option> <option value="2">two</option> 

i have php code puts table data array

<?php $return_arr = array(); $sql="select * tickets_standardresponses "; $rs=mysql_query($sql,$conn) or die(mysql_error()); while($result=mysql_fetch_array($rs)) {     $return_arr[] = array('sequence' => $result["sequence"], 'response' => $result["response"]); } $data = json_encode($return_arr); ?> <script type="text/javascript"> $(document).ready(function(){     var data = <?php echo $data; ?>;     $('#standard_response').on('change',function() {      }); }); </script> 

how can fill textarea based on selected option

for example, if selected option's value = 1 want put response data array sequence = 1

i not want use get/post requests using ajax

        var data = <?php echo $data; ?>;          $('#response').on('change', function() {              var sequence = $(this).val();             //check each object in data array             $.each(data, function( index, obj ) {                 if (obj.sequence === sequence) {                     //the "result" textarea                     $('#result').text(obj.response);                 }             });         }); 

you have loop through data array , check each objects sequence , see if matches value of selected option.

note: make sure sequence parameter string or convert option value integer.
