如果没有代码,我们真的无法为您提供帮助,即使我已经看到您不能,如果您可以修改代码的某些部分(例如变量和数据)应该会很酷...
不过,我会尽力解释
您要做的是根据给定的 id(或其他数据)对绑定在表上的数据数组重新排序以识别它。
我为您的需求做了一个类似的例子,但我再说一遍,我真的不能穷尽:
父组件:
<template>
<div id="app">
<listone :list="listOne" :toggled="toggledParent"></listone>
<listtwo :list="listTwo" v-model="toggledParent"></listtwo>
</div>
</template>
<script>
export default {
name: "App",
data: () => ({
toggledParent: 0,
listOne: [
{
id: 1,
title: "parent1",
},
{
id: 2,
title: "parent2",
},
{
id: 3,
title: "parent3",
},
],
listTwo: [
{
title: "title1",
parent: 3,
},
{
title: "title2",
parent: 1,
},
{
title: "title3",
parent: 2,
},
],
}),
components: {
listone: () => import("@/components/listone"),
listtwo: () => import("@/components/listtwo"),
},
};
</script>
<style>
#app {
font-family: "Avenir", Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
display: flex;
flex-flow: row nowrap;
justify-content: space-between;
}
</style>
ListOne 组件:
<template>
<div class="list">
<a v-for="item in treatedList" :key="item.title">
{{ item.title }}
</a>
</div>
</template>
<script>
export default {
name: "listone",
props: {
list: Array,
toggled: Number,
},
computed: {
treatedList: function () {
let tmp = this.list;
let $this = this
return tmp.sort(function (a, b) {
return a.id === $this.toggled ? -1 : b.id === $this.toggled ? 1 : 0;
});
},
},
};
</script>
<style>
.list {
display: flex;
flex-flow: column nowrap;
}
.list > a {
border: 1px solid red;
}
</style>
ListTwo 组件:
<template>
<div class="list">
<a
v-for="item in list"
:key="item.title"
@click="$emit('input', item.parent)">
{{ item.title }}
</a>
</div>
</template>
<script>
export default {
name: "listtwo",
props: {
list: Array,
toggledParent: Number
},
};
</script>
<style scoped>
.list {
display: flex;
flex-flow: column nowrap;
}
.list > a {
border: 1px solid red;
}
</style>
试试看,告诉我它对你有什么帮助
