<link rel="stylesheet" href="${request.contextPath}/statics/plugins/layui-v2.3.0-rc1/layui/css/layui.css">

<input type="text" class="form-control" id="applyData" v-model="busWorkOrder.applyData" placeholder="申请日期"/>

var vm = new Vue({
    el:'#rrapp',
    data:{
        busWorkOrder: {}
    },
    updated: function () {
        layui.use('laydate', function() {
            var laydate = layui.laydate;
            laydate.render({
                elem: '#applyData',
                done: (value) => {
                    vm.busWorkOrder.applyData = value
                }
            });
            laydate.render({
                elem: '#chinaTime', //指定元素
                done: function(value, date) { //监听日期被切换
                    vm.busWorkOrder.chinaTime = value;
                }
            });
        })
