我有这个组件

<template>
    <div class="row py-2">
        <div class="col-sm-12">
            <v-checkbox @clicked="changeStatus($event)" :val="checkFont" :key="'checkfont'">
                <span>Activar/Desactivar</span>
            </v-checkbox>
        </div>
        <transition name="fade">
            <div class="col-sm-12" v-if="checkFont == true">
                <div v-for="(type, key) in types">
                    <div class="my-2">
                        <h5 class="text-capitalize">{{ type.label }}</h5>
                    </div>  
                    <div class="my-2">

                        </div>
                    </div>


                </div>
            </div>
        </transition>
    </div>
</template>
<script>
    const SelectPicker = () => import('../admin/selectpicker')
    const CustomCheckbox = () => import('./customCheckbox')
    export default {
        data : function() {
            return {
                fonts   : [{family : ''}],
                types   : {
                    headers : {

                console.log($event);
                this.types[key].variant = v;

            variantText : function(v) {
                return v.indexOf('00') !== -1 ? v.split('00').join('00 ') : v;
            }
        }
    }
</script>

这是v-checkbox组件。

<template>
    <div class="cntr">
        <label for="cbx" class="label-cbx">
            <input id="cbx" type="checkbox" :model="val" class="invisible" @change="checked = checkCheckbox(checked)" :checked="checked">
            <div class="checkbox">
                <svg width="20px" height="20px" viewBox="0 0 20 20">
                    <path d="M3,1 L17,1 L17,1 C18.1045695,1 19,1.8954305 19,3 L19,17 L19,17 C19,18.1045695 18.1045695,19 17,19 L3,19 L3,19 C1.8954305,19 1,18.1045695 1,17 L1,3 L1,3 C1,1.8954305 1.8954305,1 3,1 Z"></path>
                    <polyline points="4 11 8 15 16 6"></polyline>
                </svg>
            </div>
            <slot></slot>
        </label>
    </div>
</template>
<script>
    export default {
        props : ['val'],
        data : function() {
            let data = {
                checked : false
            };
            return data
        },
        methods : {
            checkCheckbox : function(checkbox) {
                this.$emit('clicked', {
                    value : this.val
                });
                let status = eval(checkbox) == true ? false : true;
                return status;
            }
        }
    }
</script>

问题出在v-checkbox中，一切正常，直到我单击v-for="(v, index) in getVariants(key)" :key="index"触发的the v-checkbox :key="'checkfont'"中的动态v-checkbox之一，因此{{{ 1}}属性值更改

我正在使用vue devtools检查组件，我可以看到checkFont属性具有正确的值，但是当单击该事件时会发出一个布尔值，然后触发:val，为什么会这样发生？我不能使用这样的组件吗？我该如何解决？

Answer 1

我意识到问题出在id的{{1}}上，每个checkbox的ID为checkbox，因此它总是在点击时调用第一个元素

动态添加时在第一个组件上单击的组件触发事件
