}
.pinPage{
background: url('timg.jpeg') no-repeat;
background-size: 100% 100%;
overflow: hidden;
width: 400px;
height: 200px
}
input{

}
input{

}
</style>
</head>
<body>
<div id="root">
<div class="pinPage">
<input type="text" v-model="currentNumber">
<div class="inputBtnList">
<button @click="traceNumber" v-for="(item, key) in buttons" :key = "key">{{item}}</button>
</div>
</div>
</div>
<script>
new Vue({
el: '#root',
data () {
return {
currentNumber: '',
buttons: [1, 2, 3, 4, 5, 6, 7, 8, 9, 'Clear', 0, 'Undo']
}
},
methods: {
traceNumber: function(event){
const btnText = event.target.textContent
if(btnText === 'Clear'){
this.currentNumber = ''
}else if(btnText === 'Undo'){
this.currentNumber = this.currentNumber.substring(0, this.currentNumber.length -1)
}else{
this.currentNumber += btnText
}
}
}
}
)
</script>
</body>
</html>
做出效果图(css样式仍有待改进)：
