clicking the edit button initializes the edited content, but when opened, the value of the select component is not selected by default. Why? The 
 code is as follows: 
<FormItem :label="$t("dictionary_type")" prop="type_id">
    <Select v-model="dictionaryItem.type_id">
        <Option v-for="dicType in dicTypes" :value="dicType.id" :key="dicType.id">{{ dicType.dic_name }}</Option>
    </Select>
</FormItem>
when you click to edit, it will be assigned a value:
open (row) {
    let _this = this;
    _this.dictionaryItemId = row.id;
    _this.dictionaryItem.type_id = row.type_id;
    _this.dictionaryItem.item_name = row.item_name;
    _this.dictionaryItem.item_value = row.item_value;
    _this.dictionaryItem.sort = parseInt(row.sort);
    _this.dictionaryItem.comment = row.comment;
    _this.showModal = true;
}
 after opening, it is shown in the following figure 
  
some people say that check to see if dictionaryItem.type_id is congruent value,. How to check this?
