1.设置:【:ref=“‘XXX’ + index”】XXX -->自定义ref的名字
2.获取:let ref = eval(‘this.$refs.XXX’ + index)[0]
<template>
<div class="ref_test">
<div v-for="(item, index) in dataList" :key="index" :ref="'refName' + index" @click="clickGetRef(index)">
<p>{{ item.title }}</p>
</div>
</div>
</template>
<script>
export default {
data() {
return {
dataList: [
{
"id": 1,
"title": "这是来测试如何获取动态ref的"
},
{
"id": 2,
"title": "第2条数据"
},
{
"id": 3,
"title": "第3条数据"
},
{
"id": 4,
"title": "第4条数据"
},
]
}
},
methods: {
clickGetRef(index) {
let ref = eval('this.$refs.refName' + index)[0]
console.log(ref);
}
},
}
</script>
<style></style>
1.设置:【:ref=“‘XXX’ + (index+i)”】或者【:ref=“‘XXX’ + id”】
index+i -->两个for循环的索引;
id -->item的唯一标识;
2.获取:
let ref = eval('this.$refs.XXX' + (index + i))[0]
或者
let ref = eval('this.$refs.XXX' + (item.id))[0]
3.示例:
<template>
<div>
<div class="ref_double_test">
<div v-for="(item, index) in dataLists" :key="index">
<div class="content" v-for="(sonItem, i) in item.sonList" :key="index + i" @click="clickGetDoubleRef(index, i, sonItem)">
<!-- 方式一:用索引的方式,用一个索引可能会重复,为防止重复,则用两个索引【index + i】 -->
<div :ref="'refName1' + (index + i)">{{ item.title }}</div> ----
<!-- 方式二:用id的方式 -->
<div :ref="'refName2' + sonItem.sonId">{{ sonItem.sonContent }}</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
dataLists: [
{
"id": 1,
"title": "第1条数据",
"sonList": [
{ "sonId": 1, "sonContent": "子集第1条数据" },
{ "sonId": 2, "sonContent": "子集第2条数据" },
]
},
{
"id": 2,
"title": "第2条数据",
"sonList": [
{ "sonId": 11, "sonContent": "子集第11条数据" },
{ "sonId": 22, "sonContent": "子集第22条数据" },
]
},
{
"id": 3,
"title": "第3条数据",
"sonList": [
{ "sonId": 111, "sonContent": "子集第111条数据" },
{ "sonId": 222, "sonContent": "子集第222条数据" },
]
}
]
}
},
methods: {
clickGetDoubleRef(index, i, sonItem) {
// 方式一
let ref1 = eval('this.$refs.refName1' + (index + i))[0]
console.log('ref1', ref1);
// 方式二
let ref2 = eval('this.$refs.refName2' + sonItem.sonId)[0]
console.log('ref2', ref2);
}
},
}
