这次给大家带来怎样使用vue引入js数字小键盘，使用vue引入js数字小键盘的注意事项有哪些，下面就是实战案例，一起来看一下。
效果如图：
代码如下：
keyboard.vue
<template>
<p class="keyboard" v-show="showKeyboard" v-clickoutside="closeModal">
<p v-for="keys in keyList">
<template v-for="key in keys">
<i v-if="key === 'top'" @click.stop="clickKey" class="iconfont icon-zhiding tab-top"></i>
<i v-else-if="key === '123'" @click.stop="clickKey" class="tab-num">123</i>
<i v-else-if="key === 'del'" @click.stop="clickKey" id="del" class="iconfont icon-delete key-delete"></i>
<i v-else-if="key === 'blank'" @click.stop="clickKey" class="iconfont icon-konggejian-jianpanyong tab-blank"></i>
<i v-else-if="key === 'symbol'" @click.stop="clickKey" class="tab-symbol">符</i>
<i v-else-if="key === 'point'" @click.stop="clickKey" class="tab-point">·</i>
<i v-else-if="key === 'enter'" @click.stop="clickKey" class="iconfont icon-huiche tab-enter"></i>
<i v-else @click.stop="clickKey" >{{key}}</i>
</template>
</p>
</p>
</template>
<script>
import clickoutside from '../../directives/clickoutside'
export default {
directives: { clickoutside },
data() {
return {
keyList: [],
status: 2,//0 小写 1 大写 2 数字 3 符号
lowercase: [
['7', '8', '9'],
['4', '5', '6'],
['1', '2', '3'],
['.','0','del'],
],
//equip:!!navigator.userAgent.toLocaleLowerCase().match(/ipad|mobile/i)//是否是移动设备
}
},
props: {
option: {
type: Object
}
},
computed: {
showKeyboard(){
return this.option.show
}
},
mounted() {
this.keyList = this.lowercase
},
methods: {
tabHandle({ value = '' }) {
if(value.indexOf('tab-num') > -1){
this.status = 2
//数字键盘数据
}else if(value.indexOf('key-delete') > -1){
console.log(value.indexOf('key-delete'))
this.emitValue('delete')
}else if(value.indexOf('tab-blank') > -1){
this.emitValue(' ')
}else if(value.indexOf('tab-enter') > -1){
this.emitValue('\n')
}else if(value.indexOf('tab-point') > -1){
this.emitValue('.')
}else if(value.indexOf('tab-symbol') > -1){
this.status = 3
}else if(value.indexOf('tab-top') > -1){
if(this.status === 0){
this.status = 1
}else{
this.status = 0
this.keyList = this.lowercase
}
}else{
}
},
clickKey(event) {
// if(event.type === 'click' && this.equip) return
let value = event.srcElement.innerText;
let id = event.srcElement.id;
let target = event.srcElement ? event.srcElement : event.target;
if(id !== '' && id === 'del'){//如果点击的是id为del的表示是删除
this.emitValue(id);
}else{//否则
value && id !== 'del'? this.emitValue(value) : this.tabHandle(target.classList);
}
},
emitValue(key) {
console.log(key)
this.$emit('keyVal', key)
},
closeModal(e) {
if (e.target !== this.option.sourceDom) {
// this.showKeyboard = false
this.$emit('close', false)
}
}
}
}
