vue 權限控制按鈕3種樣式、內容、以及跳轉事件

最近碰到一個因為要根據權限來給一個按鈕變成不同功能，

簡單寫出3個按鈕然后用v-if也能實現這個功能，但是在加載頁面時，如果延遲過高則會把按鈕按照DOM順序加載出來，這是個很不好的效果

思索了下，把三個功能分開寫，目前但說能達到需求，但個人感覺還不是最好解決辦法，在此記錄下來以待將來發現更好辦法

 

<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">立即預約</span>
                    <span v-show="items.msg==2">已預約</span>
                    <span v-show="items.msg==3">已過期</span>
                </span>
            </div>
