I get a syntax error after JQuery upgrade from 1.51 to 2 -

-

the code hasn't changed jquery version. simplified version of ajax call is:

   $.ajax(     {         type: 'get',         url: mappath($(this).attr('path')),         cache: false,         data: '{}',         datatype: 'html',         success: function (result) {             console.log(result);             if ($(result).filter('#feedback').length > 0) {                 $('#center').children(':first').before($(result).filter('#feedback').outerhtml());             }             else {                 $('#feedback').remove();                 $('#dialog').html(result);                 $('#dialog').dialog('option', 'title', 'edit mailbox');                 $('#dialog').dialog('open');             }         }     });

just before if statement log result. shows expected formatted html snippet. snippet meaning contains div child elements. when use selector in if statement error:

throw error("syntax error, unrecognized expression:

i can use console view contents of result , if try selector error. error if use:

$(result)

however if modify result , prepend <html><body> , append </body></html> works no error. changed jquery break , how work around it? result needs html snippet setting container on page value.

since can't see html string, can't point out causing not work $(), fixing should easy using $.parsehtml() on result first. if doesn't parse properly, html invalid.

result = $.parsehtml(result); console.log(result); if ($(result).filter('#feedback').length > 0) {     $('#center').children(':first').before($(result).filter('#feedback').outerhtml()); } else {     $('#feedback').remove();     $('#dialog').html(result);     $('#dialog').dialog('option', 'title', 'edit mailbox');     $('#dialog').dialog('open'); }
