嘎嘎好用的虚拟键盘第二弹之中文输入法

news 2025/8/6 7:09:22

之前还在为不用研究输入中文而暗自窃喜这不新需求就来了（新需求不会迟到它只是在路上飞一会儿）
找到了个博主分享的代码是好使的 @前端-xyq 已经和原作者申请转载了感谢~~

抄的过程中发现诶？这不我之前用的那个虚拟键盘组件吗这货还带中文呢
是的他带上一篇还有人问我能不能中文输入我之前瞪两眼珠子活拉就是没看见

在这里插入图片描述

原作者的方法就是能实现的套了两层组件keyboard-input 和 simpleKeyboard
两个utils的js方法 core.js隐藏键盘和 mixins.js 表单字段校验(这里用element-ui el-form的prop validate校验也行)

用的过程中发现有两个报错
1.点击关闭if (button == ‘{close}’) 会报

在这里插入图片描述
if里改成如下代码即可

	if (button == '{close}') {let arr = document.querySelectorAll('.hg-theme-default');arr.forEach((ele) => {ele.style.visibility = 'hidden';});return false;}

2.中英文切换时会报错
在这里插入图片描述
改成如下代码即可

        if (this.keyboard.options.layoutCandidates !== null) {this.displayDefault = {'{bksp}': 'backspace','{lock}': 'caps','{tab}': 'tab','{shift}': 'shift','{change}': '中文','{space}': ' ','{clear}': '清空','{close}': '关闭',},this.keyboard.setOptions({layoutCandidates: null,display: this.displayDefault,});} else {this.displayDefault = {'{bksp}': 'backspace','{lock}': 'caps','{tab}': 'tab','{shift}': 'shift','{change}': '英文','{space}': ' ','{clear}': '清空','{close}': '关闭',},this.keyboard.setOptions({layoutCandidates: layout.layoutCandidates,display: this.displayDefault,});}

我这里修改了simpleKeyboard内的部分代码做了点样式调整

<template><div :class="keyboardClass"></div>
</template><script>
import Keyboard from 'simple-keyboard';

import layout from 'simple-keyboard-layouts/build/layouts/chinese'; // 中文输入法export default {name: 'SimpleKeyboard',props: {keyboardClass: {default: 'simple-keyboard',type: String,},input: {type: String,default: '',},},data: () => ({keyboard: null,}),mounted() {this.keyboard = new Keyboard(this.keyboardClass, {onChange: this.onChange,onKeyPress: this.onKeyPress,...layout});this.setKeyboard()},methods: {setKeyboard() {this.keyboard.setOptions({layoutName: "shift",layoutCandidatesPageSize: 10,theme: "hg-theme-default hg-layout-default myTheme",layout: {// 默认布局default: ['` 1 2 3 4 5 6 7 8 9 0 - = {bksp}','{tab} q w e r t y u i o p [ ] \\',"{lock} a s d f g h j k l ; '",'{shift} z x c v b n m , . / {clear}','{change} {space} {close}',],// 切换shift布局shift: ['~ ! @ # $ % ^ & * ( ) _ + {bksp}','{tab} Q W E R T Y U I O P { } |','{lock} A S D F G H J K L : "','{shift} Z X C V B N M < > ? {clear}','{change} {space} {close}',],},buttonTheme: [{class: 'hg-red close',buttons: '{close}',},{class: 'hg-red change',buttons: '{change}',},],display: {'{bksp}': 'backspace','{lock}': 'caps','{tab}': 'tab','{shift}': 'shift','{change}': '英文','{space}': ' ','{clear}': '清空','{close}': '关闭',}});},onChange(input) {this.$emit('onChange', input);},// 点击键盘onKeyPress(button, $event) {console.log("onKeyPress -> $event", $event)if (button == '{close}') {let arr = document.querySelectorAll('.hg-theme-default');arr.forEach((ele) => {ele.style.visibility = 'hidden';});return false;} else if (button == '{change}') { // 切换中英输入法        if (this.keyboard.options.layoutCandidates !== null) {this.displayDefault = {'{bksp}': 'backspace','{lock}': 'caps','{tab}': 'tab','{shift}': 'shift','{change}': '中文','{space}': ' ','{clear}': '清空','{close}': '关闭',},this.keyboard.setOptions({layoutCandidates: null,display: this.displayDefault,});} else {this.displayDefault = {'{bksp}': 'backspace','{lock}': 'caps','{tab}': 'tab','{shift}': 'shift','{change}': '英文','{space}': ' ','{clear}': '清空','{close}': '关闭',},this.keyboard.setOptions({layoutCandidates: layout.layoutCandidates,display: this.displayDefault,});}} else if (button == '{clear}') {this.keyboard.clearInput();} else {let value = $event.target.offsetParent.parentElement.children[0].children[0].value;if (value) {this.keyboard.setInput(value);}        }this.$emit('onKeyPress', button);/*** If you want to handle the shift and caps lock buttons*/if (button === '{shift}' || button === '{lock}') this.handleShift();},handleShift() {let currentLayout = this.keyboard.options.layoutName;let shiftToggle = currentLayout === "default" ? "shift" : "default";this.keyboard.setOptions({layoutName: shiftToggle});} },watch: {input(input) {this.keyboard.setInput(input);},},
};
