页面的head部分，需引入必要的样式和JS插件，代码如下：

<link type="text/css" rel="stylesheet" href="css/ydui.css?rev=@@hash"/>
<link type="text/css" rel="stylesheet" href="css/demo.css"/>
<script type="text/javascript" src="js/ydui.flexible.js"></script>

页面的body部分，section里吗嵌套了多个div标签，代码如下：

<section class="g-flexview">
    <section class="g-scrollview">
        <div class="m-celltitle">默认调用</div>
        <div class="m-cell">
            <div class="cell-item">
                <div class="cell-left">所在地区：</div>
                <div class="cell-right cell-arrow">
                    <input type="text" class="cell-input" readonly id="J_Address" placeholder="请选择收货地址">
                </div>
            </div>
        </div>

        <div class="m-celltitle">设置默认值</div>
        <div class="m-cell">
            <div class="cell-item">
                <div class="cell-left">所在地区：</div>
                <div class="cell-right cell-arrow">
                    <input type="text" class="cell-input" readonly id="J_Address2" value="新疆 乌鲁木齐市 天山区" placeholder="请选择收货地址">
                </div>
            </div>
        </div>
    </section>
</section>

页面的底部，需引入jQuery库及必要的级联插件，并设置好相关事件的响应和必要参数，代码如下：

<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/ydui.citys.js"></script>
<script type="text/javascript" src="js/ydui.js"></script>
<script type="text/javascript">
//默认调用
!function () {
	var $target = $('#J_Address');

	$target.citySelect();

	$target.on('click', function (event) {
		event.stopPropagation();
		$target.citySelect('open');
	});

	$target.on('done.ydui.cityselect', function (ret) {
		$(this).val(ret.provance + ' ' + ret.city + ' ' + ret.area);
	});
}();
//设置默认值
!function () {
	var $target = $('#J_Address2');

	$target.citySelect({
		provance: '新疆',
		city: '乌鲁木齐市',
		area: '天山区'
	});

	$target.on('click', function (event) {
		event.stopPropagation();
		$target.citySelect('open');
	});

	$target.on('done.ydui.cityselect', function (ret) {
		$(this).val(ret.provance + ' ' + ret.city + ' ' + ret.area);
	});
}();
</script>
