Bootstrap-multiselect显示隐藏div元素

Question

I am using bootstrap-multiselect for my task to show hide dynamic div's element based on multiple selected checkboxes. The StackOverflow question I found here is only exposed about how to show hide multiselect based on selected multiselect, not div.

HTML code :

<select id="one" multiple="multiple">
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

<select id="two" multiple="multiple">
  <option data-group="1" value="OneA" disabled>One A</option>
  <option data-group="1" value="OneB" disabled>One B</option>
  <option data-group="2" value="TwoA" disabled>Two A</option>
  <option data-group="2" value="TwoB" disabled>Two B</option>
  <option data-group="3" value="ThreeA" disabled>Three A</option>
</select>

JavaScript code:

$(document).ready(function() {
  $('#one').multiselect({
    onChange: function(element, checked) {
      var opts = $('*[data-group="' + element.val() + '"]');
      console.log(opts);
      if (checked === true) {
        opts.prop('disabled', false).prop('selected', false);
      } else if (checked === false) {
        opts.prop('disabled', true).prop('selected', false);
      }
      $("#two").multiselect('refresh');
    }
  });
  $('#two').multiselect();
});

Besides, I am a beginner on bootstrap and jQuery. Could someone help me how to solve this issue please. Thank you.

This can be easily achieved.

For instance, add following Divs along your html code indicated above:

<div data-group="1">data-group="1"</div>
<div data-group="2">data-group="2"</div>
<div data-group="2">data-group="2"</div>
<div data-group="3">data-group="3"</div>
<div data-group="3">data-group="3"</div>

and can easily manage Hide/Show of Divs in your js using:

opts.css({'display':'none'}); // to hide

opts.css({'display':'block'}); // to show

<script>
    $(document).ready(function() {
        $('#one').multiselect({
            onChange: function(element, checked) {
                var opts = $('*[data-group="' + element.val() + '"]');
                console.log(opts);
                if (checked === true) {
                    opts.prop('disabled', false).prop('selected', false);
                    opts.css({'display':'block'});
                } else if (checked === false) {
                    opts.prop('disabled', true).prop('selected', false);
                    opts.css({'display':'none'});
                }
                $("#two").multiselect('refresh');
            }
        });
        $('#two').multiselect();
    });

</script>

You may customize it as you wish. eg, you may need to change data-group to myDiv-group for div elements and modify the javascript accordingly.

Hope this helped :)
