javascript - jQuery show/hide a div based on select value

Question

I have a select list with values 'all' and 'custom'. On select with value 'custom' a div with class 'resources' should appear, and if the value is 'all' it should be hidden.

Form is:

<div>
    <label>Privileges:</label>
    <select name="privileges" id="privileges" class="" onclick="craateUserJsObject.ShowPrivileges();">
        <option id="all" value="all">All</option>
        <option id="custom" value="custom">Custom</option>
    </select>
</div>
<div class="resources" style=" display: none;">resources</div>

And javascript for this is:

ShowPrivileges: function() {
    var Privileges = jQuery('#privileges');
    var select = this.value;
    Privileges.change(function() {
        if (select === 'custom') {
            $('.resources').show();
        }
    });
}

How should this look in order to work? Sorry, I know this should be simple, but I am new with all this.

You need to use val method:

var Privileges = jQuery('#privileges');
var select = this.value;
Privileges.change(function () {
    if ($(this).val() == 'custom') {
        $('.resources').show();
    }
    else $('.resources').hide(); // hide div if value is not "custom"
});
