php - How to disable a select option populated by database in javascript based on time range -


i working on project in values fetched database in select options. consider if options consist of 5 options aa,bb,cc,dd,ee. problem want disable options aa , dd (or such other combination or individual option) after clock hits 11.30 on thursday , again enable on 11.30 on sunday.

<form id="main-order-form"  name="order-form" method="post" action="" role="form">   <div class="row">     <div class="col-md-8">        <div class="row">         <div class="col-md-4">           <div class="form-group">             <label for="offercode" style="color:#fff">               offer code:</label>               <select id="offercode"  name="choose_code"                class="form-control" tabindex="1" style="width:100%" required>               <option value="">choose one:</option>               <?php                 $query = "select id,code offercode";                 $result = mysqli_query($conn, $query);                 while ($rows = mysqli_fetch_assoc($result)) {                   $code_id = $rows['id'];                                                      $code_name = $rows['code'];                   echo"<option value='$code_id'>$code_name</option>";                 }               ?>             </select>           </div>         </div>         <div class="col-md-4">           <div class="form-group">             <label for="foodtype" style="color:#fff">               veg / non-veg :</label>               <select id="foodtype" name="foodtype" class="form-               control" tabindex="2" style="width:100%" required>               <option value="" selected="">choose one:               </option>               <option value="veg">veg</option>               <option value="non-veg">non-veg</option>             </select>           </div>         </div>         <div class="col-md-4">           <div class="form-group">             <label for="quantity" style="color:#fff">               quantity :</label>               <div class="input-group">                 <span class="input-group-btn">                   <button type="button" class="btn btn-default btn-number"                    disabled="disabled" data-type="minus" data-field="quantity">                   <span class="glyphicon glyphicon-minus"></span>                 </button>               </span>               <input type="text" name="quantity" class="form-control input-number"                tabindex="3" value="1" min="1" max="20" >               <span class="input-group-btn">                 <button type="button" class="btn btn-default btn-number" data-                 type="plus" data-field="quantity">                 <span class="glyphicon glyphicon-plus"></span>               </button>             </span>           </div>         </div>       </div>     </div>   </div>   <div class="col-md-4">      <label for="submit-order" style="color:#fff">       submit order :</label>       <input type="submit" name="submit-order"        style="background-color:#c70039;color:#000" id="" tabindex="4" class="form-       control btn btn-login" value="submit">          </div>   </div> </form>  <script type="text/javascript">   function timer () {     time = new date();      var hh = time.gethours();     var mm = time.getminutes();     var dd = time.getday();      if (hh > "11" && mm == "30" && dd == "0,1,2,3,4") {       // disable "offercode" select options (not specified        // option) sunday 11.30 thursday 11.30     } else {       // else keep enable     }   } </script>

you add custom data- attribute identify relevant option elements (e.g. queryselector) , set disabled attribute each option. 

element.disabled=true;

edit:

to disable specified offercodes here 1 approach:

var select = document.getelementbyid('offercode'); var arrayofcodestodisable = ['aa', 'bb']; disableoptions(select, arrayofcodestodisable)  function disableoptions(select, arrayofcodestodisable) {     (var = 0; < select.options.length; i++) {       if (arrayofcodestodisable.indexof(select.options[i].text) > -1) {           select.options[i].disabled = true;       }     } }

in array "arrayofcodestodisable" define relevant offercodes. options of selectbox checked innerhtml (text) , disabled if contain text of array.
