Vue3实现点击按钮实现文字变色功能 |
1.动态样式实现1.1核心代码解释:
<span class="power-station-perspective-item-text" @click="clickItem(item.id)" :style="{ color: isChecked(item.id) ? '#cc7e17' : '' }"> {{ item.title }} </span> 1.2源代码<template> <div class="power-station-perspective"> <div class="flow-chart-container-item"> <div class="power-station-perspective-title flow-chart-container-item-parent"> {{ title }} </div> <div v-for="item in buttonGroupsArr" :key="item.id" class="power-station-perspective-item flow-chart-container-item location" > <span class="power-station-perspective-item-text" @click="clickItem(item.id)" :style="{ color: isChecked(item.id) ? '#cc7e17' : '' }"> {{ item.title }} </span> </div> </div> </div> </template> <script setup> import {ref, onMounted} from "vue"; const title = ref("菜单项"); const buttonGroupsArr = ref([ {title: "按钮1", id: 0}, {title: "按钮2", id: 1}, {title: "按钮3", id: 2}, {title: "按钮4", id: 3}, {title: "按钮5", id: 4}, ]); const checkedItem = ref(0); const isChecked = (param) => { return checkedItem.value === param; }; const clickItem = (param) => { checkedItem.value = param; }; onMounted(() => { }); </script> <style scoped> .power-station-perspective{ width: 200px; } .flow-chart-container-item-parent { width: 100%; background: linear-gradient(90deg, rgba(0, 136, 234, 0.84) 0%,rgba(31, 38, 83, 0.85) 101.82%); } .flow-chart-container-item { display: grid; text-align: center; padding: 3px 5px 3px 3px; margin-bottom: 3px; align-items: center; } .power-station-perspective-item { background: rgba(0, 46, 79, 0.5); } .location { cursor: pointer; } .power-station-perspective-item-text { margin: 0 auto; cursor: pointer; } .power-station-perspective-title { margin-bottom: 3px; } </style> 2.动态类名2.1核心代码解释说明:
:class="['power-station-perspective-item-text', { 'active-power-station-perspective-item-text': isChecked(item.id) } ]"> 2.2源代码<template> <div class="power-station-perspective"> <div class="flow-chart-container-item"> <div class="power-station-perspective-title flow-chart-container-item-parent"> {{ title }} </div> <div v-for="item in buttonGroupsArr" :key="item.id" class="power-station-perspective-item flow-chart-container-item location" > <span class="power-station-perspective-item-text" @click="clickItem(item.id)" :class="[ 'power-station-perspective-item-text', { 'active-power-station-perspective-item-text': isChecked(item.id) } ]"> {{ item.title }} </span> </div> </div> </div> </template> <script setup> import {ref, onMounted} from "vue"; const title = ref("菜单项"); const buttonGroupsArr = ref([ {title: "按钮1", id: 0}, {title: "按钮2", id: 1}, {title: "按钮3", id: 2}, {title: "按钮4", id: 3}, {title: "按钮5", id: 4}, ]); const checkedItem = ref(0); const isChecked = (param) => { return checkedItem.value === param; }; const clickItem = (param) => { checkedItem.value = param; }; onMounted(() => { }); </script> <style scoped> .power-station-perspective{ width: 200px; } .flow-chart-container-item-parent { width: 100%; background: linear-gradient(90deg, rgba(0, 136, 234, 0.84) 0%,rgba(31, 38, 83, 0.85) 101.82%); } .flow-chart-container-item { display: grid; text-align: center; padding: 3px 5px 3px 3px; margin-bottom: 3px; align-items: center; } .power-station-perspective-item { background: rgba(0, 46, 79, 0.5); } .location { cursor: pointer; } .power-station-perspective-item-text { margin: 0 auto; cursor: pointer; } .active-power-station-perspective-item-text{ color: #cc7e17; } .power-station-perspective-title { margin-bottom: 3px; } </style> 3.实现效果到此这篇关于Vue3实现点击按钮实现文字变色功能的文章就介绍到这了,更多相关Vue3点击按钮文字变色内容请搜索以前的文章或继续浏览下面的相关文章希望大家以后多多支持! |
