标签组件的效果如下
组件作用
- 这是一个div,包含了两个文本框,后面是添加和删除按钮
- 添加按钮复制出新的div,除了文本框没有内容,其它都上面一样
- 删除按钮将当前行div删除
组件实现
<template>
<div>
<template v-for="(item,index) in tags">
<el-row :gutter="4" style="margin:5px;">
<el-col :span="8">
<el-input v-model="item.authorName" placeholder="作者名称"/>
</el-col>
<el-col :span="8">
<el-input v-model="item.authorUnit" placeholder="作者单位名称"/>
</el-col>
<el-col :span="4">
<el-button type="text" @click="addAuthor">添加</el-button>
<span style="padding:2px;">|</span>
<el-button type="text" @click="delAuthor(index)">删除</el-button>
</el-col>
</el-row>
</template>
</div>
</template>
<script>
export default {
name: "AuthorUnit",
props: {dic: {type: Array, default: []}},
data() {
return {
tags: [],
};
}, created() {
if(this.dic!=null && this.dic.length>0){
this.tags = this.dic;//关键字初始化,dic的值来自于父组件(调用它的组件叫父组件)
}
},
methods: {
addAuthor() {
this.tags.push({authorName: '', authorUnit: ''});
},
delAuthor(index) {
this.tags.splice(index, 1);
},
},
}
</script>
调用组件,为组件传默认值
<el-form-item label="作者信息" prop="articleAuthorList">
<author-unit v-model="form.articleAuthorList" :dic="form.articleAuthorList"/>
</el-form-item>
测试代码
提交之后,将出现当前你添加的这个列表的对象,对接后端接口,将这个数组POST到后端即可,如图所示:
