功能需求：封装一个带有设计好的样式的输入组件，输入方式为模拟的数字键盘。
键盘组件为VueTouchKeyboard,下载方式如下
npm install "vue-touch-keyboard" --save

封装的输入组件
模板
<template>
<div v-clickoutside="hide">
<input v-bind="$attrs"
@focus="show"
@blur="submit" />
<div class="keyboard__warn-mess keyboard__warn">
<div v-if=warnMessage
class="">
{{warnMessage}}
</div>
</div>
<vue-touch-keyboard class="keyboard-nav"
:options="options"
v-if="visible"
:cancel="hide"
:layout="layout"
:accept="hide"
:input="input" />
</div>
</template>
很简单，就包含了一个VueTouchKeyboard模拟键盘和input输入框，以及一个div里放动态的warnMessage
js内容：
<script>
import VueTouchKeyboard from 'vue-touch-keyboard';
import 'vue-touch-keyboard/dist/vue-touch-keyboard.css';
import $ from 'jquery';
const clickoutside = {//自定义命令，功能：点击键盘以外的区域隐藏键盘
// 初始化指令
bind (el, binding, vnode) {
function documentHandler (e) {
// 这里判断点击的元素是否是本身，是本身，则返回
if (el.contains(e.target)) {
return false;
}
// 判断指令中是否绑定了函数
if (binding.expression) {
// 如果绑定了函数 则调用那个函数，此处binding.value就是handleClose方法
binding.value(e);
}
}
// 给当前元素绑定个私有变量，方便在unbind中可以解除事件监听
el.__vueClickOutside__ = documentHandler;
document.addEventListener('click', documentHandler);
},
update () { },
unbind (el, binding) {
// 解除事件监听
document.removeEventListener('click', el.__vueClickOutside__);
delete el.__vueClickOutside__;
},
};
export default {
components: {
'vue-touch-keyboard': VueTouchKeyboard.component,
},
directives: { clickoutside },
data: function () {
return {
visible: false,
input: null,
options: {
useKbEvents: false,
preventClickEvent: false
}
};
},
props: {
warnMessage: { type: String, default: null },//错误提示
layout: { type: String, default: 'normal' },//键盘的种类：normal:全键盘/numeric：数字/compact：字母
instanceID: String,
},
methods: {
accept () {
this.hide();
},
show (e) {
this.input = e.target;
if (!this.visible) { this.visible = true }
},
hide () {
this.visible = false;
},
submit () {
if (this.input === null) {
return;
}
this.$emit('data-change', this.input.value);
},
},
watch: {
warnMessage: {
handler () {
// debugger;
const doubleId = `#${this.instanceID}`;
if (this.warnMessage !== '' && this.warnMessage != null) {
$(doubleId).find('input').css('border', '1px solid rgba(255, 0, 90, 1)');
} else {
$(doubleId).find('input').css('border', 'none');
}
},
},
},
}
</script>
页面内容(只简单的展示了下组件的使用)
<template>
<div>
<div class="display-flex-css">
<span class="keyboard-lable">{{$t('messages.order_no')}}</span>
<touch-keyboard type="number"
id="order-no-K"
:placeholder="$t('messages.pls_input_orderno')"
:maxlength="13"
v-model="orderno"
instanceID="order-no-K"
:warnMessage="ordernoWarn"
@data-change="getOrderNo"
layout="numeric"></touch-keyboard>
</div>
<div class="display-flex-css">
<span class="keyboard-lable">{{$t('messages.phoneNum')}}</span>
<touch-keyboard type="number"
id="phone-num-K"
:placeholder="$t('messages.pls_input_phoneNum')"
:maxlength="11"
v-model="phoneNum"
instanceID="phone-num-K"
:warnMessage="phoneNumWarn"
@data-change="getPhoneNum"
layout="numeric"></touch-keyboard>
</div>
<button class="confirm-btn"
@click="confirm">确定</button>
</div>
</template>
<script>
import touchKeyboard from '@/components/keyboard';
export default {
components: {
'touch-keyboard': touchKeyboard,
},
data () {
return {
orderno: '',
ordernoWarn: '',
phoneNum: '',
phoneNumWarn: ''
}
},
methods: {
getOrderNo (value) {
this.orderno = value;
},
getPhoneNum (value) {
this.phoneNum = value;
},
confirm () {
this.ordernoWarn = "";
this.phoneNumWarn = "";
if (this.orderno == "") {
this.ordernoWarn = "订单号不能为空";
} else if (this.phoneNumWarn == "") {
this.phoneNumWarn = "手机号不能为空";
}
}
}
}
</script>
<style lang="scss">
.display-flex-css {
display: flex;
justify-content: center;
}
.keyboard-lable {
font-size: 22px;
padding-right: 26px;
line-height: 46px;
}
.confirm-btn {
width: 150px;
height: 43px;
font-size: 21px;
border-radius: 8px;
background: #9800ff29;
border: 0px;
margin-top: 17%;
}
</style>
页面效果：（随便画的，比较丑）
