vue element-ui select框选中回显

我们先看看通过接口回来的数据.

{
    "message":"success",
    "status":200,
    "data":[
        {
            "id":2,
            "rule_list":"{"title":[".item-text>h3","text"],"link":[".item-tit>a","href"]}",
            "range_list":".item-phototext",
            "author":"中华游戏网",
            "name":"中华游戏网",
            "handle":"chinaGame",
            "url":"[https://game.china.com/news/jx/](https://game.china.com/news/jx/)",
            "rule_content":"{"title":["h1","text"],"link":["#chan_newsDetail","html"]}",
            "range_content":"",
            "encoding":0,
            "status":1,
            "full_url":"",
            "gather_types":1,
            "defaultType":{
                "id":1,
                "name":"新闻"
            }
        }
    ]
}

其中，defaultType是需要回显的内容，即原选定的分类.

需要保证select下拉的ID和v-model里边的id保持一致

<el-form-item label="所属元素:" prop="defaultType">
      <el-select v-model="ruleForm.defaultType.id" placeholder="请选择对应分类" @change="obtainValue">
      <el-option v-for="getType in ruleForm.defaultType" :key="getType.id" :label="getType.name" :value="getType.id"></el-option>
    </el-select>
    </el-form-item>
