now want selected value of 5th subject store in mysql table. not able value of option selected in 2nd drop down.

how can selected value items dynamically added in option tag

here code

<script> function setsubject(objlanguage) {     var objmedia = document.getelementbyid("5thsub");     objmedia.options.length = 0;         objmedia.disabled = false;      switch (objlanguage.value) {     case "humanity":         objmedia.options.add(new option("hindi"));         objmedia.options.add(new option("ip"));          break;     case "commerce":         objmedia.options.add(new option("ip"));         objmedia.options.add(new option("other"));         break;     case "sci[pcm]":         objmedia.options.add(new option("cs"));         objmedia.options.add(new option("ip"));         break;     case "sci[pcb]":         objmedia.options.add(new option("ip"));         objmedia.options.add(new option("math"));         break;     default:         objmedia.options.add(new option("select"));         objmedia.disabled = true;         break;     } } </script> <tr>     <td>stream : &nbsp;&nbsp;&nbsp;&nbsp;         <select name="stream" id="stream" onchange="setsubject(this)">            <option> select</option>            <option value="humanity">humanity</option>            <option value="commerce">commerce</option>            <option value="sci[pcm]">sci[pcm]</option>            <option value="sci[pcb]">sci[pcb]</option>         </select>     </td>     <td>5th subjects :                <select name="5thsub" id="5thsub" disabled="disabled">             <option>select</option>         </select>     </td> </tr>

part of form data passed savedata.php file saving value.

<td>category : &nbsp;&nbsp;&nbsp;&nbsp;<select name="cast_cate" >            <option value="gen"<?php if(isset($_post['cast_cate'])){if($_post['cast_cate']=="gen"){?>selected <?php }} ?>>general</option>         <option value="sc" <?php if(isset($_post['cast_cate'])){if($_post['cast_cate']=="sc"){?>selected <?php }} ?>>sc</option>         <option value="st" <?php if(isset($_post['cast_cate'])){if($_post['cast_cate']=="st"){?>selected <?php }} ?>>st</option>         <option value="crem" <?php if(isset($_post['cast_cate'])){if($_post['cast_cate']=="crem"){?>selected <?php }} ?>>obc - creamy</option>         <option value="ncrem" <?php if(isset($_post['cast_cate'])){if($_post['cast_cate']=="ncrem"){?>selected <?php }} ?>>obc - non-creamy</option>          </select> </td>

you can add "hidden" input object contains value of second select box, , write simple function assign value box:

add js:

function setvalue() {     document.getelementbyid("selected_value").value = document.getelementbyid("5thsub").value; }

than change first select box, run function:

<select name="stream" id="stream" onchange="setsubject(this);setvalue()">

last, make second select box run function:

<select name="5thsub" id="5thsub" disabled="disabled" onchange="setvalue();">

now reading selected value easier you.

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
