Dieses Mal bringe ich Ihnen Vue, um den Tastatureffekt zu realisieren. Was sind die Vorsichtsmaßnahmen für Vue, um den Tastatureffekt zu realisieren?
In verschiedenen Apps werden häufig benutzerdefinierte Tastaturen verwendet. In diesem Beispiel wird vue2 verwendet, um eine einfache Tastatur zu implementieren, die auf Mobilgeräten und PCs verwendet werden kann
Keyboard.vue

KeyInput.vue
<template> <p> <input type="text" ref="keyboard" v-model="inputValue" @focus="onFocus"> <Keyboard :option="option" @keyVal="getInputValue" @close="option.show = false"></Keyboard> </p> </template> <script> import Keyboard from '../components/Keyboard' export default { components: { Keyboard }, data() { return { option: { show: false, sourceDom: '' }, inputValue: '' } }, props: {}, created() {}, methods: { getInputValue(val) { if(val === 'delete'){ this.inputValue = this.inputValue.slice(0,this.inputValue.length -1) }else{ this.inputValue += val } }, onFocus() { this.$set(this.option, 'show', true) this.$set(this.option, 'sourceDom', this.$refs['keyboard']) }, //获取光标位置 getCursorPosition() { let doc = this.$refs['keyboard'] if (doc.selectionStart) return doc.selectionStart return -1 }, //设置光标位置 暂未实现 setCursorPosition(pos) { let doc = this.$refs['keyboard'] console.log(doc.setSelectionRange) doc.focus() doc.setSelectionRange(1,3) } } } </script> <style lang="less" scoped> </style>
Demo verwenden
<template> <p> <key-input class="demo-class"></key-input> </p> </template> <script> import KeyInput from '../components/KeyInput' export default { components: { KeyInput }, data() { return { } }, created() {}, methods: { } } </script> <style lang="less"> body{ background: #efefef; } .demo-class{ input{ border:1px solid #ccc; outline: none; height: 30px; font-size: 16px; letter-spacing: 2px; padding: 0 5px; } } </style>
