我试图实现的是：
当我选择选项"；Alle openstaande"；(result_id=0(，我想选择所有这些result_id:[-1，-2，-3，-5，-7，-8，-11，-12]并取消选择result_id 0。
var mergedResults返回需要选择的result_id数组
我不知道如何通过方法添加到当前选择的选项中
我的刀片文件包含：
<dd-results
naam="resultcodes-select"
v-model="selected.resultcodes"
:select-all="true"
:multiple="true"
:openstaande="true"
:include-ids="true"
:project-id="selected.project"
title="@lang('rapportage.resultcode')"
:include-negative="true"
return-key="result_id"
>
</dd-results>
我的vue文件：
<template>
<span>
<label v-if="title">{{title}}</label>
<v-select
:options="results"
label="naam"
:placeholder="placeholderText"
:close-on-select="closeOnSelectValue"
:disabled="isDisabled"
:multiple="multiple"
:value="value"
@input="handleInput($event)"
:loading="isLoading"
:reduce="reduceKey"
>
<div slot="no-options">{{geenOptiesTekst}}</div>
</v-select>
</span>

我能够通过handleInput($event)中的$emit实现这一点。(现在看起来很明显，但我当时不知道this.$emit('input', $event);做了什么(
我改变了这三种方法：
handleInput($event) {
this.$emit('input', $event);
if($event.includes(0)) {
this.addOpenstaande($event);
}
},
addOpenstaande(value) {
var openstaandeResult = [-1,-2,-3,-5,-7,-8,-11,-12];
var mergedResults = [... new Set (value.concat(openstaandeResult))];
const removeIndex = mergedResults.indexOf(0);
if (removeIndex > -1) {
mergedResults.splice(removeIndex, 1);
}
this.$emit('input', mergedResults);
},
reset(selected=false) {
// 1. verwijder de geselecteerde itemboxes
$(this.$el).find('.vs__selected').remove();
setTimeout(() => {
// 2. herstel de placeholder
$(this.$el).find('.vs__selected-options input').attr('placeholder', this.placeholderText);
}, 100);
}
