layer.confirm 弹出一个选取起止日期的弹窗，用的layerData 但是弹出之后没有选择日期的效果，layer.confirm 怎么初始化才能选择起止日期？
<body>
<button id="show">show</button>
<div id="time">
<div class="layui-inline">
<label class="layui-form-label">日期范围</label>
<div class="layui-input-inline">
<input type="text" class="layui-input" id="test6" placeholder=" - ">
</div>
</div>
</div>
<script type="text/javascript">
$(function(){
laydate.render({
elem: '#test6',
range: true
});
$("#show").click(function(){
var show = $("#time").html();
layer.confirm(show,{
title: "日期选择",
btn: ['确认', '取消'],
},function(){
},function(){
})
});
})
</script>
</body>
