php - Jquery Ajax Insert Extremely Slow -

-

i having tough time trying figure out why onblur, triggers ajax call taking long time finish. takes dozens of seconds @ times. seems more of "description" fields have, longer takes. can review code, , tell me if think i'm missing something?

var description; var id; $(".description").live('blur',function() {    var success;    var datatype;    $(".dynamic_row,<?php echo $services; ?>").each(function() {       var row = $(this);       var id = row.find(".id").val() || 0;       var description = row.find(".description").val() || "";       var q = <?php echo $q; ?>;       $.ajax({          type: "post",          url: 'setdescname.php',          data: {ider:id, descriptionr:description, qr:q},          success: function(result) {             if(result.isok == false)                alert(result.message);             },             datatype: datatype       });    }); });

<?php echo $services; ?> pulls in 16 names of possible dynamic rows activated checkbox. part works fine...

this code in setdescname.php

require_once('include/database.php');  if (!dbconnect()) {     echo 'error connecting database';     exit; }  $id = $_post['ider']; $description = $_post['descriptionr']; $q = $_post['qr'];  $qry = "update items set description = '".$description."' id = '".$id."'";  $result = mysql_query($qry) or die(mysql_error());

if think matters, have following earlier in code.

$.ajaxsetup({async:false}); $.ajaxsetup({cache:false});

this required, because users in ie, , cache ajax calls, rendering addition of new "dynamic" fields without necessary functionality (bringing mysql_insert_id() on new adds).

all of work, it's painfully slow...

i appreciate advice or suggestions. thanks.

for fast need ajax cache , ajax async

ajax cache

$.ajax({ url: '/?=testdefault', data: { 'cache': 'default' } });//no timestamp

$.ajaxsetup({ cache: false }); $.ajax({ url: '/?=testfalse/', data: { 'cache': 'false' } });//yes, timestamp  $.ajaxsetup({ cache: true }); $.ajax({ url: '/?=testtrue/', data: { 'cache': 'true' } }); //no timestamp

for ajax async

$.ajax({           url: "super.php",           data: "a="+a,           type: "post",           async: false,           success: function(data) {             alert(data);           }     });
