用vue写了个移动端车牌输入键盘
话不多说，先看图
初学vue，断断续续花了一天半才写出来.... 写样式真的很麻烦 下面上代码
html
1 <template> 2 <section class="pkey-contain"> 3 <section class="pkey-win"> 4 <header class="pkey-header">车牌号码</header> 5 <div class="pkey-win-body"> 6 <div class="pkey-ipt pkey-foucs">{{plate}}</div> 7 <div class="pkey-tips">{{tips}}</div> 8 </div> 9 </section> 10 <section class="pkey-keyboard"> 11 <header class="pkey-header2"> 12 <label class="pkey-chacelbtn" @click="closewin">取消</label><label class="pkey-okbtn" @click="checkplate">完成</label> 13 </header> 14 <section class="pkey-keyscontain"> 15 <ul> 16 <li v-show="txtboardshow" v-for="(item,index) in cartxt"> 17 <span v-show="index==cartxt.length-1" @click="txtboardshow=false,numboardshow=true">ABC</span> 18 <label v-for="(items,indexi) in item" @click="txtclick(items,indexi,item.length)">{{items}}</label> 19 <span v-show="index==cartxt.length-1" @click="plate=plate.substr(0, plate.length-1)"> </span> 20 </li> 21 <li v-show="numboardshow" v-for="(item,index) in numtxt"> 22 <span v-show="index==cartxt.length-1" @click="txtboardshow=true,numboardshow=false">字</span> 23 <label v-for="(items,indexi) in item" @click="numclick(items,indexi,item.length)">{{items}}</label> 24 <span v-show="index==cartxt.length-1" @click="plate=plate.substr(0, plate.length-1)"> </span> 25 </li> 26 </ul> 27 </section> 28 <transition name="fade"> 29 <section class="showkey" v-show="keyshow" :keyshow="keyshow" :style="{marginLeft:mleft+'px'}">{{keyb}}</section> 30 </transition> 31 </section> 32 </section> 33 </template>

样式也是第一次用大神推荐的vw做适配，真的蛮方便（之前一直用flexible.js）但是有个问题：怎么能设置固定宽度，因为用电脑打开的话整个页面很大...看起来很夸张,而且因为它是根据视口做的适配吧 max-width也不好用,求各位朋友教教我.
