php - jQuery ui autocomplete ipv4 -

-

i'm using jquery ui autocomplete helper in form. when try use search list of available ips never filter results, no matter number of characters (numbers) type returns complete list. how can correct it? using code http://jqueryui.com/autocomplete/#remote-with-cache json generated php file similiar (i have reduced number of results):

["192.168.3.2","192.168.3.3","192.168.3.4","192.168.3.5","192.168.3.6","192.168.3.7","192.168.3.8","192.168.3.9","192.168.3.10"]

[edit]

the form page code:

<!doctype html> <html lang="en">     <head>         <meta charset="utf-8" />         <title>jquery ui autocomplete - remote caching</title>         <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />         <script src="http://code.jquery.com/jquery-1.9.1.js"></script>         <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>         <link rel="stylesheet" href="/resources/demos/style.css" />         <style>             .ui-autocomplete-loading {                 background: white url('images/ui-anim_basic_16x16.gif') right center no-repeat;             }         </style>         <script>             $(function() {                 var cache = {};                 $("#birds").autocomplete({                     minlength: 2,                     source: function(request, response) {                         var term = request.term;                         if (term in cache) {                             response(cache[ term ]);                             return;                         }                         $.getjson("tab-ip-autocomplete.php", request, function(data, status, xhr) {                             cache[ term ] = data;                             response(data);                         });                     }                 });             });         </script>     </head>     <body>         <div class="ui-widget">             <label for="birds">birds: </label>             <input id="birds" />         </div>     </body> </html>

the php json code:

<?php include_once 'conn.php';  inet_ntoa(ipv4) :ipv4";  $autocomplete = "select * vteste;";  $sth = $dbh->prepare($autocomplete); $sth->bindparam(':ipv4', $ipv4, pdo::param_str); $sth->execute(); $sth->setfetchmode(pdo::fetch_assoc); $row = $sth->fetch();   /* gera json */  $arr = array();  while ($row = $sth->fetch()):     $arr[] = $row['ipv4']; endwhile;  $json = json_encode($arr); echo $json; ?>

when using remote datasource, jqueryui autocomplete doesn't filter results - down script provides data send on matching results.

from http://api.jqueryui.com/autocomplete/#option-source:

the autocomplete plugin not filter results, instead query string added term field, server-side script should use filtering results. example, if source option set "http://example.com" , user types foo, request made http://example.com?term=foo. data can in same format local data described above.

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...
