父组件:
<template>
     <div class="btnHandle">
        <el-button type="info" size="small" @click="addBook">添加书籍</el-button>

       <add-edit-book 
          :AddBookTitle="AddBookTitle" 
          :dialog-form-visible="addBookOnoff"
          @dialog-cancel="cancelRegister"
          >
        </add-edit-book>
    </div>
</template>

<script>
import AddEditBook from '@/book/bookRuleManageMent/addeditBookDialog'
export default {
  name: 'BookCategory',
  components: {
      AddEditBook
  },
  data () {
    return {
        AddBookTitle: '添加书籍',
        addBookOnoff: false
    }
  },
    methods: {
        addBook () 
            this.AddBookTitle = '添加书籍',

楼主,你好!是因为你给子组件传的参数名字不对啊,子组件定义的是 props -> addBookOnoff ,父组件传的却是 dialog-form-visible。所以对话框不会展示出来。


如有帮助,麻烦点击下采纳,谢谢~
