Vue.js “Maximum call stack size exceeded” 错误。为子级使用对话框并将数据从父级传递给子级失败

Question

我正在研究 Vuetify.js，我是 Vue 的新手，我引用了这个文档 Vuetify Dialogs用于从此链接创建 Matheus Dal'Pizzol 的对话和解决方案 Open a Vuetify dialog from a component template in VueJS将其分离到组件。结果我有子组件作为对话框，如下所示

父级

    <template>
      <v-container fluid>
        <v-row dense>
          <v-col cols="12">
            <v-btn large color="success">Add product</v-btn>
          </v-col>
          <v-col cols="3" v-for="product in products" :key="product.id">
            <v-card class="mx-auto" outlined>
              <v-list-item three-line>
                <v-list-item-content>
                  <v-list-item-title class="headline mb-1">{{product.name}}</v-list-item-title>
                  <v-list-item-subtitle>{{product.title}}</v-list-item-subtitle>
                </v-list-item-content>
              </v-list-item>
              <v-card-actions>
                <v-btn dark color="cyan" @click.stop="showScheduleForm = true">
                  <v-icon dark>mdi-television</v-icon>
                </v-btn>
                <v-btn color="primary">Detail</v-btn>
              </v-card-actions>
            </v-card>
            <modal-detail v-model="showScheduleForm" :productDetailInfo="product"></modal-detail>
          </v-col>
        </v-row>
      </v-container>
    </template>

    <script>
    import axios from "axios";
    import ModalDetail from "./ModalDetail.vue";
    export default {
      name: "HelloWorld",
      components: {
        ModalDetail
      },
      data: function() {
        return {
          showScheduleForm: false,
          products: [],
          errors: []
        };
      },
    ...

child

    <template>
      <v-dialog v-model="show" max-width="500" v-if="Object.keys(productDetailInfo).length !== 0">
        <v-card>
          <v-card-title class="headline grey lighten-2" primary-title>{{ productDetailInfo.name }}</v-card-title>

          <v-card-text>{{ productDetailInfo.title }}</v-card-text>

          <v-divider></v-divider>

          <v-card-actions>
            <v-spacer></v-spacer>
            <v-btn color="green darken-1" text @click.stop="show = false">Close</v-btn>
            <v-btn color="primary">Detail</v-btn>
          </v-card-actions>
        </v-card>
      </v-dialog>
    </template>
    <script>
    export default {
      name: "ModalDetail",
      props: {
        productDetailInfo: {
          type: Object
        },
        value: Boolean
      },
      computed: {
        show: {
          get() {
            return this.value;
          },
          set(value) {
            this.$emit("input", value);
          }
        }
      }
    };
    </script>

但是，当我单击 icon-button“超出最大调用堆栈大小”时出现异常。似乎有一个连续的循环发生。请帮忙!我错过了什么吗？

那是因为你的v-dialog在v-for循环中，很常见problem .要解决此问题，请将 :retain-focus="false" 作为 Prop 添加到您的 v-dialog
