vue 权限控制按钮3种样式、内容、以及跳转事件

最近碰到一个由于要根据权限来给一个按钮变成不一样功能，

简单写出3个按钮而后用v-if也能实现这个功能，可是在加载页面时，若是延迟太高则会把按钮按照DOM顺序加载出来，这是个很很差的效果

思索了下，把三个功能分开写，目前但说能达到需求，但我的感受还不是最好解决办法，在此记录下来以待未来发现更好办法

 

<div class="btn60">
                <span v-on:click="reserveMainLink()" :class="{'weui_btn':items.msg!=3,'weui_btn_primary':items.msg==1,'weui_btn_warn':items.msg==2}" >
                    <span v-show="items.msg==1">当即预定</span>
                    <span v-show="items.msg==2">已预定</span>
                    <span v-show="items.msg==3">已过时</span>
                </span>
            </div>
