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
