autocomplete - JQuery - Get calling element id -

problem

in source function of autocomplete want selector's id. there way can travese through call stack , this? jquery have level of abstraction?

why?

i have multiple autocompletes on page , each 1 handled differently on server side. have use function source. otherwise have used url + data: long time ago =p

jquery version

jquery-1.9.1

research

of course i've been on this: jquery api

how element id dynamically generated form elements jquery?

a lot of these attempts didn't think work, right i'm @ point of trial , error.

$(this).attr('id'); - undefined

caller function name

i though i'd try caller functions name, , it...doesn't seem output anything.

appending source function (this absurd!!! appending text function?! i'm desperate...)

 $("#inpdvehmk").autocomplete({             source: autocompletepost + "field="+$(this).attr('id'),             minlength: 2,             select: function(event, ui){                 alert(ui.label1);                 alert("value= " + ui.item.value + " id= "+ ui.item.id);             }         }); 

auto complete setup

    $("#inpdvehmk").autocomplete({         source: autocompletepost,         minlength: 2,         select: function(event, ui){             alert(ui.label1);             alert("value= " + ui.item.value + " id= "+ ui.item.id);         }     }); 

source function

function autocompletepost(request, response){     //alert($(this).attr('id')); //this i'm testing see ids.     $.post(ajaxpageautocomplete, { searchterm: request.term, field: 'inpdvehmk'}, //i want field dynamic depending on calling selector.         function(data) {             var splitdata = data.split("%");             var json = jquery.parsejson(splitdata[1].tostring());              if(data.search('autocompleteerror') !== -1 || data.length < 1){                 dialogbox('div_errormessage^open^autocompleteerror');             }else{                 response(json);             }         }     ); } 

i'm embarrassed how long took me figure out.

use line in source function id of autocomplete.

$(this.element).prop("id") 

since autocomplete jquery widget, this object refers widget instance. element, need go through it's element property.

jsfiddle

to fair, isn't documented unless creating widgets using widget factory.
