vue实现手机键盘
实现手机键盘的Vue方案
使用第三方库vue-touch-keyboard
安装依赖库：
npm install vue-touch-keyboard --save注册组件：
import VueTouchKeyboard from 'vue-touch-keyboard';
Vue.use(VueTouchKeyboard);模板中使用：
<vue-touch-keyboard
:layout="'qwerty'"
:input="inputField"
@change="onChange"
/>自定义键盘组件
创建Keyboard.vue组件：
<template>
<div class="virtual-keyboard">
<div v-for="row in layout" :key="row.join('')">
<button
v-for="key in row"
:key="key"
@click="handleKeyPress(key)"
>{{ key }}</button>
</div>
</div>
</template>
<script>
export default {
data() {
return {
layout: [
['1','2','3'],
['4','5','6'],
['7','8','9'],
['*','0','#']
]
}
},
methods: {
handleKeyPress(key) {
this.$emit('key-press', key);
}
}
}
</script>集成输入控制
父组件中使用：
<input v-model="inputValue" @focus="showKeyboard = true"/>
<Keyboard
v-if="showKeyboard"
@key-press="handleKeyInput"
@close="showKeyboard = false"
/>methods: {
handleKeyInput(key) {
this.inputValue += key;
}
}样式优化
添加CSS样式：
.virtual-keyboard {
position: fixed;
bottom: 0;
width: 100%;
background: #f0f0f0;
}
.virtual-keyboard button {
width: 30%;
height: 50px;
margin: 5px;
font-size: 1.2em;
}高级功能实现
添加特殊功能键：
layout: [
['1','2','3','←'],
['4','5','6','Clear'],
['7','8','9','Done'],
['.','0',' ','']
]处理功能键逻辑：
handleKeyPress(key) {
if(key === '←') {
this.$emit('backspace');
}
else if(key === 'Clear') {
this.$emit('clear');
}
else if(key === 'Done') {
this.$emit('close');
}
else {
this.$emit('key-press', key);
}
}响应式布局
使用媒体查询适配不同屏幕：
@media (min-width: 768px) {
.virtual-keyboard {
max-width: 500px;
left: 50%;
transform: translateX(-50%);
}
}输入法切换
实现多语言布局切换：
layouts: {
en: [['Q','W','E'],['A','S','D']],
zh: [['拼','音','输'],['入','模','式']]
}切换方法：
switchLanguage(lang) {
this.currentLayout = this.layouts[lang];
}
