Show/hide select optgroup options in Internet Explorer

4.1k views Asked by At

I have an issue with showing/hiding optgroup options. I tried showing them in Chrome and Internet explorer but never got to a solution that would work on both environments

   <select value="null" style="VERTICAL-ALIGN: top" id="country_code" class="elqField" name="country_code" onchange="validateStates(this.value)" > 
<option selected="true" value="">Choose One...</option>
<option value="US">United States</option>
<option value="CA">Canada</option>
</select>

 <select value="null" style="VERTICAL-ALIGN: top" id="state_code" class="elqField"name="state_code" size="1" > 
<option selected = "true" value="">Choose One...</option>

</optgroup>
</select>

I was trying to control this select list from value retrieved from another select list and I confirmed that its working properly!

    function validateStates (value){
var $sel = $('select[name="state_code"]');
  if (value == 'US'){
        $('optgroup, optgroup > option', $sel).hide();
        $('optgroup[label="United States"]', $sel).children().andSelf().show();

        console.log('hello there!!');

  }
  else if (value == 'CA'){
        $('optgroup, optgroup > option', $sel).hide();
        $('optgroup[label="Canada"]', $sel).children().andSelf().show();
 }
 else {
  $('optgroup, optgroup > option', $sel).hide();
 }
}

Any help would be more than appreciated!

Hi friend i wrote the code that is working in IE10..... please verify from your side and let me know if any issue....

<script type="text/javascript">   

    if (navigator.appName.toString() == 'Microsoft Internet Explorer') {
        var arrOptGroup = $('#state_code optgroup');
        var us = $(arrOptGroup[0]).detach();
        var ca = $(arrOptGroup[1]).detach();
    }

    function validateStates(value) {

        if (navigator.appName.toString() == 'Microsoft Internet Explorer') {                            
            if (value == 'US') {
                $('#state_code optgroup').remove();
                $('#state_code').append(us);
            }
            if (value == 'CA') {
                $('#state_code optgroup').remove();
                $('#state_code').append(ca);
            }                
            return;
        }

        var $sel = $('select[name="state_code"]');
        if (value == 'US') {
            $('optgroup, optgroup > option', $sel).hide();
            $('optgroup[label="United States"]', $sel).children().andSelf().show();

            console.log('hello there!!');

        }
        else if (value == 'CA') {
            $('optgroup, optgroup > option', $sel).hide();
            $('optgroup[label="Canada"]', $sel).children().andSelf().show();
        }
        else {
            $('optgroup, optgroup > option', $sel).hide();
        }
    }
</script>

display: none on option elements does not work consistently across browsers. Do not fight this behavior. A better solution is to .remove() the unwanted optgroup and .append() it back when necessary.
