javascript - ShowHide div using bootstrap checkbox - require inputs to be entered only if checkbox is checked - Stack Overflow

Ok, I've been having a really weird problem using a checkbox which collapses a hidden div using bootstrap.

if I have data-toggle="collapse" in the checkbox input attribute section, the Div Collapses but requires that every single one of the inputs inside it be filled out.

If data-toggle="collapse" is not there, the hidden div doesn't collapse, and if the checkbox is checked it requires the inputs to be entered and if it's left unchecked I can submit the form without the inputs being entered. (desired action, but the div doesn't hide or show when the checkbox is checked)

How do I hide/show the div when the checkbox is unchecked/checked AND only require the inputs if the box is checked?

I'm using this as the HTML:

                    <div class="col-md-1">
                    <input type="checkbox" onclick="ChangeShip()" href="#moreabout" data-toggle="collapse" aria-expanded="false" aria-controls="moreabout" class="form-control" id="chShipAdd" name="chShipAdd" value="no">
                    </div>
                    <label for="chShipAdd" class="col-md-3 control-label">Shipping Information?</label>
                        <div id="shipadddiv" style="visibility: hidden;">
                            <div class="collapse" id="moreabout" >
                                <div class="form-group">
                                    <div class="col-md-12">
                                        <br>
                                        <input id="sStreet" name="sStreet" type="text" placeholder="Street Name (required)"  class="form-control shipClass" required>
                                    </div>
                                </div>
                                <div class="form-group">
                                    <div class="col-md-4">
                                        <input id="sCity" name="sCity" type="text" placeholder="City (required)" required  class="form-control shipClass">
                                    </div>
                                    <div class="col-md-4">
                                        <input id="sState" name="sState" type="text" placeholder="State (required)" required  class="form-control shipClass">
                                    </div>
                                    <div class="hidden-lg hidden-md">&nbsp;</div>
                                    <div class="col-md-4">
                                        <input id="sZipcode" name="sZipcode" type="text" placeholder="Zip (required)" required  class="form-control shipClass">
                                    </div>
                                </div>
                            </div>  
                        </div>

and the javascript:

function ChangeShip() {
      if (!(document.getElementById('chShipAdd').checked)) {
       document.getElementById('shipadddiv').style.visibility="hidden";
       $(".shipClass").prop("disabled",true);
      }
      else {
      document.getElementById('shipadddiv').style.visibility="visible";
      $(".shipClass").prop("disabled",false);
      }
  }

Any solution that WORKS will be acceptable. I've bashed my brain all day trying to do this simple action. I've tried .prop .attribute .setAttribute .removeAttribute, and much much more.

Any Advice?

• 2 Can you simplify that question / code, and put the code in a snippit? That's a big wall of text. – Anthony Astige Commented Jun 29, 2016 at 4:06
• If I remove data-toggle="collapse" from the checkbox - the 'disabled' attribute gets set to each of the inputs in the hidden div, BUT the div doesn't collapse. If I add the data-toggle="collapse" the hidden div shows and hides itself, but regardless of if it's shown or hidden, ALL of the inputs are required. Also, the checkbox doesn't show as checked or unchecked – DMort Commented Jun 29, 2016 at 4:08

You can use jquery to solve this quickly. You can wrap your inputs for change ship and give it and id. And let jquery do the rest.

var form = $('#myForm'),
checkbox = $('#changeShip'),
chShipBlock = $('#changeShipInputs');

chShipBlock.hide();

checkbox.on('click', function() {
   if($(this).is(':checked')) {
      chShipBlock.show();
      chShipBlock.find('input').attr('required', true);
   } else {
      chShipBlock.hide();
      chShipBlock.find('input').attr('required', false);
   }
});

See this jsfiddle for your problem. This should help you.

your click event will toggle the display and the disabled, but when the form is loaded you will have hidden content that is not disabled.

simply call the function on document.ready

function ChangeShip() {
   var show = $('#chShipAdd').prop('checked');
   $('#shipadddiv').toggle(show);
   $("#shipadddiv .shipClass").prop("disabled", !show);
}

$(ChangeShip); // call on document.ready

or simply add the disabled attribute to those elements so that the initial form state is valid

If the [required] attribute is still triggered on a [disabled] element you could juggle the attribute value

function ChangeShip() {
   var show = $('#chShipAdd').prop('checked');
   $('#shipadddiv').toggle(show);
   $("#shipadddiv .shipClass").each(function(){
       if (!('_required' in this))
           this._required = this.required;

       this.disabled = !show;
       this.required = (show) ? this._required : false;
   });
}

Try to do this :

HTML :

<div class="col-md-1">
    <input type="checkbox" onclick="ChangeShip()" href="#moreabout" data-toggle="collapse" aria-expanded="false" aria-controls="moreabout" class="form-control" id="chShipAdd" name="chShipAdd" value="no">
</div>
<label for="chShipAdd" class="col-md-3 control-label">Shipping Information?</label>
<div id="shipadddiv" style="visibility: hidden;">
    <div class="collapse" id="moreabout" >
        <div class="form-group">
            <div class="col-md-12">
                <br>
                <input id="sStreet" name="sStreet" type="text" placeholder="Street Name (required)"  class="form-control shipClass" required>
             </div>
         </div>
         <div class="form-group">
             <div class="col-md-4">
                 <input id="sCity" name="sCity" type="text" placeholder="City (required)" required  class="form-control shipClass">
             </div>
             <div class="col-md-4">
                 <input id="sState" name="sState" type="text" placeholder="State (required)" required  class="form-control shipClass">
             </div>
             <div class="hidden-lg hidden-md">&nbsp;</div>
             <div class="col-md-4">
                     <input id="sZipcode" name="sZipcode" type="text" placeholder="Zip (required)" required  class="form-control shipClass">
             </div>
         </div>
    </div>  
</div>

JQUERY :

$('#chShipAdd').change(function() {
    if ($('#chShipAdd').prop('checked')) {
        $('#shipadddiv').show();
    } else {
        $('#shipadddiv').hide();
    }
});
