php - dynamically distribute values into 3 tags -


i have programming problem now. trying dynamically allocate value 3 input tags. basic idea sum of 3 inputs should not exceed value given.

so code this

<!doctype html> <html> <head>     <script type="text/javascript" src="../../jquery/jquery-1.11.0.min.js"></script>     <script type="text/javascript">     var          total = parseint($('#quantityrequired').text()),         inputs = $('input[type="number"]');          inputs             .attr('max', total)             .change(function() {          //make sure current value in range         if($(this).val() > parseint($(this).attr('max'))) {             $(this).val($(this).attr('max'));         } else if ($(this).val() < parseint($(this).attr('min'))) {             $(this).val($(this).attr('min'));         }          //get available total         var current = available();          //now update max on each input         $('input').each(function(indx) {             $(this).attr('max',  parseint($(this).val()) + total - current);         });      });      function available() {         var sum = 0;         inputs.each(function() {             sum += parseint($(this).val());         });         return sum;     }     </script> </head>  <body> <?php  $projectname    = strval($_get['project']);  $thicknessvalue = intval($_get['thicknessvalue']); $baseplatevalue = strval($_get['baseplatevalue']);  $query = "select qty_required, qty_cut component                 thickness = :thicknessval                  , project_name = :projectname                 , base_plate = :baseplateval                 , request_status = 'open'";  $result = oci_parse($conn, $query);  oci_bind_by_name($result, ":projectname", $projectname); oci_bind_by_name($result, ":thicknessval", $thicknessvalue); oci_bind_by_name($result, ":baseplateval", $baseplatevalue);  oci_execute($result); ?>  <?php while ($row = oci_fetch_array($result, oci_both)){  $qtyavailable = $row['qty_required'] - $row['qty_cut'];           echo '<span id="quantityrequired">'.$qtyavailable.'</span>';         echo '<input id="cncqty"    name="cncqty"    type="number" min="0" value="0"   placeholder="cnc" required>';                 echo '<input id="scatorqty" name="scatorqty" type="number" min="0" value="0" placeholder="scator" required>';               echo '<input id="manualqty" name="manualqty" type="number" min="0" value="0" placeholder="manual" required>';        echo '<br/>';       } ?> </body> </html>

so of code here displayed in div section of other html file. problem code is, jquery doesn't work when displayed in div. tried in jsfilddle , jquery code works well.

and jsfiddle here : http://jsfiddle.net/k2qvv/

but when apply in php code. doesn't work. doing wrong here ?

your code running before page rendered, things like:

inputs = $('input[type="number"]');

won't find anything.

to fix this, wrap javascript other available function in jquery ready:

$( document ).ready(function() {    ... });

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
