VUE3（二十五）自定义Modal对话框组件

标签：fixed   load   菜单   钩子   参数   scope   tail   camel   pointer   

接着自定义组件，这里是我自定义的一个modal对话框组件。

效果如下图所示：

Modal.vue

<template>
  <div class="modal-backdrop" v-if="modalShow">
     <div class="modal" >
        <div class="modal-header">
          <div><h3>{{title}}</h3></div>
          <div>
            <img src="/@/assets/img/close.png" class="close-img" @click="confirmModal(false)">
          </div>
        </div>
        <div class="modal-body">
          <!-- 插槽 官方文档：https://cn.vuejs.org/v2/guide/components-slots.html -->
          <slot />
        </div>
        <div class="modal-footer">
            <button type="button" class="btn-close" @click="confirmModal(false)">关闭</button>
            <button type="button" class="btn-confirm" @click="confirmModal(true)">确认</button>
        </div>
    </div>
 
  </div>
</template>
 
<style lang="scss" scoped>
  @import "../../assets/css/components/pc/Modal.scss";
</style>
 
<script lang="ts">
// 引入路由
import {  
    reactive, 
    toRefs,

export default {

    const data = reactive({
        // 菜单显示标识
        modalShow: props.modalShow
    });

     */
    const confirmModal = (sign:boolean) => {
      // 子组件向父组件传值 
      content.emit(‘confirmModal‘, sign);
    }
 
    /**

    const dataRef = toRefs(data);
    return {
      confirmModal,
      ...dataRef
    }
  },
}
</script>

Modal.scss

.close-img{
  width: 30px;margin-right: 12px; margin-top: 12px; cursor: pointer;
}
.modal-backdrop { 
    position: fixed;

    display: flex; 
    flex-direction: column;

.modal-header { 
    border-bottom: 1px solid #eee;

    justify-content: space-between;

.modal-body { 
    position: relative; 
    padding: 20px 10px;

.btn-close, .btn-confirm {    
    border-radius: 8px;

    background-color:transparent;
}
.btn-confirm {
    color: #fff; 
    background-color: #2d8cf0;
}

组件调用：

<template>
   <div @click=”openModal()”>打开模态框</div>
    <Modal v-on:confirmModal="confirmModal" :modalShow="modalShow" :title="modalTitle">

          <input type="text" placeholder="请输入您的邮箱！" v-model="email"  style="width:100%">
        </div>
      </div>
    </Modal>

        const data = reactive({

        const confirmModal = (sign: boolean) => {

            {

        }

        const openModal = (replyid:string) => {
            data.modalShow = true;
            data.replyid = replyid;
        }

        const getWangEditorReplayValue = (str: string) => {
            data.comment_content_replay = str;
        }
        /**

         */
        const dataRef = toRefs(data);
        return {
confirmModal, getWangEditorReplayValue, openModal
            ...dataRef
        }
    },
};

我这个实例中引用的是wangeditor的自定义组件，随便换成点什么都是可以的。

当然 wangeditor组件的封装后边也会说到。

有好的建议，请在下方输入你的评论。
