So rufen Sie ein Javascript auf Drop-down

Question

Ich habe die a-Dropdown-Liste. Wenn ich eine Option auswähle, möchte ich einen Kalender anzeigen. Die Dropdown-Schalter funktionieren einwandfrei, aber der Kalender wird geladen, wenn die Website das erste Mal geladen wird. Später funktioniert die Dropdown-Liste wie gewünscht. Bitte sag, wo ich den Fehler mache.

<form class="form-horizontal form-label-left top_margin"> 
         <div class="form-group"> 
        <label class="control-label col-md-3 col-sm-3 col-xs-12">Select The Class/Batch</label> 
        <div class="col-md-6 col-sm-6 col-xs-12"> 
         <select class="form-control" id="division" onchange="calendar"> 
         <option>Select One</option> 
         <option value="1">Standard 1 Divison A</option> 
         <option value="2">Standard 1 Divison B</option> 
         <option value="3">Standard 1 Divison C</option> 
         <option value="4">Standard 1 Divison D</option> 
         </select> 
        </div> 
        </div> 
        <br> 
        <br> 
        <br> 
        </form> 
        <div id="caldisplay"> 
         <div id='calendar'></div> 
        </div> 

Mein Javascripts:

<script> 
    $('#division').on('change',function(){ 
var selection = $(this).val(); 
switch(selection){ 
case "1": 
$("#caldisplay").show() 
break; 
default: 
$("#caldisplay").hide() 
} 
}); 
</script> 






    $(function() { // document ready 

    $('#calendar').fullCalendar({ 
     now: '2016-05-07', 
     editable: true, 
     aspectRatio: 1.8, 
     scrollTime: '00:00',

     resourceLabelText: 'Students', 
     resources: [

      { id: 'p', title: 'John Doe P' },

      { id: 'y', title: 'John Doe Y' }, 
      { id: 'z', title: 'John Doe Z' } 
     ], 
     events: [ 
      { id: '1', resourceId: 'b', start: '2016-05-07', end: '2016-05-07', title: 'X' }, 
      { id: '1', resourceId: 'b', start: '2016-05-06', end: '2016-05-06', title: 'X' }, 
      { id: '2', resourceId: 'c', start: '2016-05-07', end: '2016-05-07', title: 'O' }, 
      { id: '3', resourceId: 'd', start: '2016-05-06', end: '2016-05-06', title: 'O' }, 
      { id: '4', resourceId: 'e', start: '2016-05-07', end: '2016-05-07', title: 'X' }, 
      { id: '5', resourceId: 'f', start: '2016-05-07', end: '2016-05-07', title: 'X' } 
     ] 
    }); 

}); 

</script> 

Answer 1

Sie müssen keine Schalter verwenden, für nur eine einfache Funktion, die standardmäßig u es mit CSS verstecken kann oder wenn u wollen, es zu zeigen, wenn eine Auswahl anders ist, kann u verwenden IF/ELSE Aussage ..

Alles, was u tun müssen, um die Funktion wie dies nennen:

Bei Änderung Aufruf:

<select class="form-control" id="division" onchange="calendar()"> 

Funktion in JS:

function calendar() { 
     $calendar = $('#calendar'); 
     $calendar.show(); 

     $calendar.fullCalendar({ 
      now: '2016-05-07', 
      editable: true, 
      aspectRatio: 1.8, 
      scrollTime: '00:00', 
      header: { 
       left: 'prev,next', 
       center: 'title', 
       right: 'timelineMonth,timelineYear' 
      }, 
      defaultView: 'timelineMonth', 
      resourceAreaWidth: '25%', 
      resourceLabelText: 'Students', 
      resources: [ 
       { id: 'a', title: 'John Doe A' }, 
       { id: 'b', title: 'John Doe B' }, 
       { id: 'c', title: 'John Doe C' }, 
       { id: 'e', title: 'John Doe E' }, 
       { id: 'f', title: 'John Doe F' }, 
       { id: 'g', title: 'John Doe G' }, 
       { id: 'h', title: 'John Doe H' }, 
       { id: 'i', title: 'John Doe I' }, 
       { id: 'j', title: 'John Doe J' }, 
       { id: 'k', title: 'John Doe K' }, 
       { id: 'l', title: 'John Doe L' }, 
       { id: 'm', title: 'John Doe M' }, 
       { id: 'n', title: 'John Doe N' }, 
       { id: 'o', title: 'John Doe O' }, 
       { id: 'p', title: 'John Doe P' }, 
       { id: 'q', title: 'John Doe Q' }, 
       { id: 'r', title: 'John Doe R' }, 
       { id: 's', title: 'John Doe S' }, 
       { id: 't', title: 'John Doe T' }, 
       { id: 'u', title: 'John Doe U' }, 
       { id: 'v', title: 'John Doe V' }, 
       { id: 'w', title: 'John Doe W' }, 
       { id: 'x', title: 'John Doe X' }, 
       { id: 'y', title: 'John Doe Y' }, 
       { id: 'z', title: 'John Doe Z' } 
      ], 
      events: [ 
       { id: '1', resourceId: 'b', start: '2016-05-07', end: '2016-05-07', title: 'X' }, 
       { id: '1', resourceId: 'b', start: '2016-05-06', end: '2016-05-06', title: 'X' }, 
       { id: '2', resourceId: 'c', start: '2016-05-07', end: '2016-05-07', title: 'O' }, 
       { id: '3', resourceId: 'd', start: '2016-05-06', end: '2016-05-06', title: 'O' },
