var htmlobjek; var menu; var meja; var harga; var jumlah; var stok;  $(function(){     $("#barang").load("barang.php");     $("#tambah").click(function(){ if(jumlah > stok) {     alert("stok tidak terpenuhi");     $("#jumlah").focus();     exit();     } else if(jumlah < 1) {     alert("jumlah pesan tidak boleh 0");     $("#jumlah").focus();     exit();}      harga=$("#harga").val();     stok=$("#stok").val();     jumlah=$("#jumlah").val();     meja=$("#meja").val();      $("#status").html("sedang diproses. . .");     $("#loading").show();      $.ajax({     url: "tambah.php",     data: {menu:menu,meja:meja,harga:harga,jumlah:jumlah},     cache: false,     success: function(msg){     if(msg=='sukses'){         $("#status").html("berhasil disimpan");         }     else{         $("#status").html("error");         }     $("#barang").load("barang.php","meja");         }     });     }); });

this barang.php

<?php   include"db/koneksi.php";  $meja=$_get['meja'];  $brg=mysql_query("select * pemesanan no_meja='$meja' ")or die (mysql_error());   echo "<thead>         <tr>             <td>nama barang</td>             <td>jumlah beli</td>             <td>subtotal</td>             <td>tools</td>         </tr>       </thead>";  $total=mysql_fetch_array(mysql_query("select sum(subtotal) total pemesanan no_meja='$meja'"));  while($r=mysql_fetch_array($brg)){     echo "<tr>              <td>$r[nama_menu]</td>             <td><input type='text' name='jum' value='$r[jumlah]' class='span2'></td>             <td>$r[subtotal]</td>             <td><a href='pk.php?op=hapus&kode=$r[nama_menu]' id='hapus'>hapus</a></td>         </tr>";     }     echo "<tr>     <td colspan='3'>total</td>     <td colspan='4'>$total[total]</td> </tr>"; ?>

the html

<select name="meja" id="meja"> <option>--pilih meja--</option>

this want, when click 'tambah' appeared on table based on 'pilih meja'

your load function seems wrong. check sample below.

$( "#result" ).load( "barang.php", { meja: '<pass value>' }, function() {   alert( "load performed." ); });

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
