本文实例为大家分享了vue封装tabs组件案例的具体代码,供大家参考,具体内容如下
回顾封装tabs组件
熟知运用$children,$parent
的案例
生成整个容器,通过$children
拿取子组件
<template>
<div class="ll-tabs">
<div class="ll-tabs__header">
<div
class="ll-tabs__header__wrapper"
v-if="tabsArray && tabsArray.length > 0"
>
<div
v-for="tab in tabsArray"
:key="tab.name"
:class="`ll-tab__item ${activeName === tab.name ? 'is-active' : ''}`"
@click="clickTab(tab)"
>
{{ tab.label }}
</div>
</div>
</div>
<div class="ll-tabs__body"><slot></slot></div>
</div>
</template>
<script>
export default {
name: "ll-tabs",
props: ["value"],
data() {
return {
tabsArray: [],
activeName: this.value,
};
},
watch: {
value(val) {
this.setCurrentName(val);
},
},
mounted() {
this.tabsArray = this.$children;
},
methods: {
clickTab(tab) {
this.activeName = tab.name;
this.updateTab();
this.$emit("change", tab);
},
updateTab() {
this.$children.map((ele) => {
console.log(ele);
if (ele.name === this.activeName) {
ele.currentShow = true;
ele.load = true;
} else {
ele.currentShow = false;
}
});
},
setCurrentName(val) {
this.activeName = val;
},
},
};
</script>
<style lang="scss" scoped>
.ll-tabs {
width: 100%;
height: auto;
.ll-tabs__header {
width: 100%;
.is-active.ll-tab__item {
background-color: aquamarine;
}
.ll-tabs__header__wrapper:before {
color: white;
}
.ll-tabs__header__wrapper {
width: 100%;
display: flex;
align-content: center;
justify-content: flex-start;
align-items: center;
height: 30px;
padding: 1px 0;
}
.ll-tab__item {
width: fit-content;
height: 30px;
padding: 0 15px;
font-size: 14px;
background-color: transparent;
z-index: 49;
cursor: pointer;
line-height: 30px;
border: 1px rgba(100, 100, 100, 0.1) solid;
border-right: none;
&:last-of-type {
border-right: 1px rgba(100, 100, 100, 0.1) solid;
}
}
}
}
.ll-tabs__body {
padding: 10px 0;
height: auto;
background-color: transparent;
}
</style>
生成子组件,展示每个tab。
<template>
<div
v-if="!lazy || loaded || currentShow"
v-show="currentShow"
:class="`ll-tab-pane tab-${name}`"
>
<slot></slot>
</div>
</template>
<script>
export default {
name: "ll-tab-pane",
props: {
label: String,
name: String,
lazy: Boolean,
},
data() {
return {
currentShow: false,
loaded: false,
};
},
mounted() {
this.$parent.updateTab();
},
};
</script>
使用
<llTabs v-model="activeName">
<llTabsPane name="first" label="first">first</llTabsPane>
<llTabsPane name="second" label="second">second</llTabsPane>
<llTabsPane name="third" label="third">third</llTabsPane>
</llTabs>
import { llTabs, llTabsPane } from "@/components/tabs";
export default {
components: { llTabs, llTabsPane },
}
展示
