    btns: null,
    backtop: null,
    selected: '',
    sticky: -1,
    visible: {
        isHide: 'no',
        numShow: 0
    },
    speed: 400,
    show: function(me) {
        me.element.show();
    },
    hide: function(me) {
        me.element.hide();
    }
}

'floors' option

	$('#elevator').({
  	 floors: $('js-floor')
    });

}

Usage

it is easy to use, only you ovrride default options to meet your requirements what you want. the following four examples to illustrate the plugin how to use.

1. back to top【example】

HTML structure:

    <div class="elevator elevator-backtop" id="backtop" >
        <a href="javascript:;" class="js-backtop">TOP</a>
    </div>

Javascript:

    $('#backtop').ielevator({
        backtop: $('#backtop .js-backtop')
    });

the example is very easy, only to get the "back to top" reference, and then [back to top] works

2. simulate elelvator【example】

HTML structure:

    <div class="elevator" id="elevator" data-elevator-options='{"selected": "custome-selected"}'>
        <ul>
            <li><a href="javascript:;" class="custome-selected js-btn">floor1</a></li>
            <li><a href="javascript:;" class="js-btn">floor2</a></li>
            <li><a href="javascript:;" class="js-btn">floor3</a></li>
            <li><a href="javascript:;" class="js-btn">floor4</a></li>
            <li><a href="javascript:;" class="js-btn">floor5</a></li>
            <li><a href="javascript:;" class="js-btn">floor6</a></li>
            <li><a href="javascript:;" class="js-btn">floor7</a></li>
        </ul>
    </div>

Javascript:

    $('#elevator').ielevator({
        floors: $('.js-floor'),
        btns: $('#elevator .js-btn'),
        selected: 'selected',
        visible: {isHide: 'yes', numShow: 400},
        show: function() {
            $('#elevator').slideDown(400);
        },
        hide: function() {
            $('#elevator').slideUp(400);
        }
    });

NOTE: data-ielevator-options='{"selected": "custome-selected"}' is the highest priority. therefore, 'custome-selected' will overwrite 'selected' in configuration object

3. simulate elevator + back to top【example】

HTML structure:

    <div class="elevator" id="elevator" data-elevator-options=''>
        <ul>
            <li><a href="javascript:;" class="custome-selected js-btn">floor1</a></li>
            <li><a href="javascript:;" class="js-btn">floor2</a></li>
            <li><a href="javascript:;" class="js-btn">floor3</a></li>
            <li><a href="javascript:;" class="js-btn">floor4</a></li>
            <li><a href="javascript:;" class="js-btn">floor5</a></li>
            <li><a href="javascript:;" class="js-btn">floor6</a></li>
            <li><a href="javascript:;" class="js-btn">floor7</a></li>
            <li><a href="javascript:;" class="js-backtop">TOP</a></li>
        </ul>
    </div>

Javascript:

    $('#elevator').ielevator({
        floors: $('.js-floor'),
        btns: $('#elevator .js-btn'),
        backtop: $('#elevator .js-backtop'),
        selected: 'selected',
        visible: {isHide: 'yes', numShow: 400},
        show: function() {
            $('#elevator').slideDown(400);
        },
        hide: function() {
            $('#elevator').slideUp(400);
        }
    });

4. require.js example【demoAMD】

5. 模拟segmentfault文章导航【example】

Javascript:

    // 获取Markdown中的标题
    var $demo = $('#demo'),
        $titles = $('h2'),
        $nav = $demo.find('.list'),
        $highlight = $demo.find('.highlight'),
        STR = '';
    // 填充标题
    $titles.each(function(){
        STR += '<li><a>'+ $(this).text() +'</a></li>';
    });
    $nav.html(STR);
    // 调用ielevator
    $demo.ielevator({
        floors: $titles,
        btns: $('#demo li'),
        sticky: 10,
        selected: $highlight
    });
