Jquery targeting different element with shared class

[Muptrulty]

basically i'm attempting to target elements only within the parent \[code\]db_update\[/code\] div class of the input field that triggers on blur, however it's targeting any class with a matching name, which is not what I want. Ignore the AJAX part as it's irrelevant for now. I think the problem lies with it targeting the input element on blur, and it's not able to chain to the parent element successfully. Basically whichever URL input box i click on is which fields it should fill out, not both.http://jsfiddle.net/SXWXu/6/HTML\[code\]<div class="db_update"><p style="font-size: 12px;"><span style="font-weight: normal;">SLIDE URL: <input type="text" class="slide_URL" /></span></p><div class="status_message"> </div><p style="font-size: 12px;"><span style="font-weight: normal;">Slide #: <input type="text" class="slide_num" readonly/></span></p><p style="font-size: 12px;"><span style="font-weight: normal;">Document #: <input type="text" class="doc_num" readonly/></span></p><p style="font-size: 12px;"><span style="font-weight: normal;">Filter(F): <input type="text" class="filter_num" readonly/></span></p></div><br/><div class="db_update"><p style="font-size: 12px;"><span style="font-weight: normal;">SLIDE URL: <input type="text" class="slide_URL" /></span></p><div class="status_message"> </div><p style="font-size: 12px;"><span style="font-weight: normal;">Slide #: <input type="text" class="slide_num" readonly/></span></p><p style="font-size: 12px;"><span style="font-weight: normal;">Document #: <input type="text" class="doc_num" readonly/></span></p><p style="font-size: 12px;"><span style="font-weight: normal;">Filter(F): <input type="text" class="filter_num" readonly/></span></p></div>\[/code\]Jquery\[code\]$(document).ready(function() {$('input[class=slide_URL]').on({ blur: function(){ var status_message = $('.status_message'); var query_string = encodeURIComponent($(this).val()); var dataString = 'query_string='+ query_string; $.ajax({ type : 'GET', url: '', dataType : 'json', data: dataString , error : function(XMLHttpRequest, textStatus, errorThrown) { $(this).parent().find('.slide_num').val(140); $('.doc_num').val(140); $('.filter_num').val(140); status_message.removeClass().addClass('failure').text('Request was not sent.').show(200);}, success : function(data) { if (data.error === true) { status_message.show().removeClass('success').addClass('failure').text(data.msg).stop().fadeOut(3000); } else { status_message.show().removeClass('failure').addClass('success').text(data.msg).stop().fadeOut(3000); } } }); return false; } }); });\[/code\]
