jquery - Access element after append -


i've read through every post can find on topic , have tried many "solutions" doesn't seem working me.

$(function () {      var options = {         source: [             "actionscript",             "applescript",             "asp",             "basic",             "c",             "c++",             "clojure",             ],         minlength: 2     };        $('#btn_addline').on ("click", function () {          // existing line number , increment 1         var linenum = parseint ($('#numlines').val()) + 1;          // update hidden numlines field new value         $('#numlines').val(linenum);          // define new field names         var line_field = 'report['+linenum+'][line]';         var notes_field = 'report['+linenum+'][notes]';         var contact_field = 'report['+linenum+'][contact]';          var newline = $('<tr> \             <td><input name="'+line_field+'" id="'+line_field+'" type="text" size="2" maxlength="2" class="form" value="'+linenum+'" readonly="readonly" /></td> \             <td><input name="'+notes_field+'" id="'+notes_field+'" type="text" size="96" maxlength="256" class="form" /></td> \             <td><input name="'+contact_field+'" id="'+contact_field+'" onfocus="attach_autocomplete()" type="text" size="32" maxlength="32" class="form" value="test123" /></td> \             </tr>');          // append new line table         //$('#report_items').append(newline);          $('#report_items').append(newline)             .hide()             .fadein('normal', function() {                 $(this).find('#'+contact_field).val('test');                 //alert ($(this).find('#'+contact_field).val());                 alert (contact_field);                 alert ($('#'+contact_field).val());             });          //$('#'+contact_field).autocomplete(options);      }); });

the new html appended properly, nothing can access elements. i've tried various suggestions throughout site , frustrated , hoping help.

the third alert - alert ($('#'+contact_field).val()); - returns "undefined".

to clear, have thoroughly gone through list of similar questions, have not found solution. possible missing obvious, or don't quite understand relation between appending elements , it's effect on dom, in case use hand here.

cheers.

the problem have special characters within selector. you'd need escape 2 backslashes \\:

to use of meta-characters ( such !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) literal part of name, must escaped with 2 backslashes: \. example, element id="foo.bar", can use selector $("#foo\.bar").

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
