Bootstrap - Select all checkbox with javascript

I have the following HTML structure using bootstrap. I need to select a checkbox to select all the checkboxes but the javascript codes I've been testing have not worked (I'm not very good at javascript). I think these codes do not work because they do not take into account the "active" class that uses bootstrap.

    <form action="" method="post" class="form-horizontal">
        <fieldset>
            <!-- Form Name -->
            <legend>EXAMPLE</legend>
            <div class="form-group rowauto" data-toggle="buttons">
                <label for="selectall">SELECT/UNSELECT ALL:</label>
                <label class="btn btn-success active checkboxkox">
                    <input type="checkbox" id="selectall" name="selectall" autocomplete="off" checked>
                    <span class="glyphicon glyphicon-ok"></span>
                </label>
            </div>
        </fieldset>
        <hr/>
        <fieldset>
            <div class="row rowauto">
                <div class="col-sm-1">
                    <div class="form-group rowauto" data-toggle="buttons">
                        <label class="btn btn-success active checkboxkox">
                            <input type="checkbox" id="check_1" name="check_1" autocomplete="off" checked>
                            <span class="glyphicon glyphicon-ok"></span>
                        </label>
                    </div>                  
                </div>
            </div>
            <div class="row rowauto">
                <div class="col-sm-1">
                    <div class="form-group rowauto" data-toggle="buttons">
                        <label class="btn btn-success active checkboxkox">
                            <input type="checkbox" id="check_2" name="check_2" autocomplete="off" checked>
                            <span class="glyphicon glyphicon-ok"></span>
                        </label>
                    </div>                  
                </div>
            </div>
        </fieldset>
        <hr/>
    </form>
