VUE实现富文本编辑以及组件传值的使用总结

VUE实现使用富文本编辑，如下图：

 

 

实现这个富文本编辑需要以下步骤：

第一步：安装编辑器组件
　　　　npm install vue-quill-editor –-save

第二步：创建一个Ue.vue的文件，放如下代码

<template>
  <div>
    <script id="editor" type="text/plain"></script>
  </div>
</template>
<script>
  export default {
    name: \'UE\',
    data() {
      return {
        editor: null
      }
    },
    props: {
      defaultMsg: {
        type: String
      },
      config: {
        type: Object
      }
    },
    mounted() {
      const _this = this;
      this.editor = UE.getEditor(\'editor\', this.config); // 初始化UE
      this.editor.addListener("ready", function () {
        _this.editor.setContent(_this.defaultMsg) // 确保UE加载完成后，放入内容。
      });
    },
    methods: {
      getUEContent() { // 获取内容方法
        return this.editor.getContent()
      }
    },
    destroyed() {
      this.editor.destroy()
    }
  }

</script>

第三步：创建一个font.css给定样式，需要引入

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=SimSun]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=SimSun]::before {
  content: "宋体";
  font-family: "SimSun";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=SimHei]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=SimHei]::before {
  content: "黑体";
  font-family: "SimHei";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=Microsoft-YaHei]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=Microsoft-YaHei]::before {
  content: "微软雅黑";
  font-family: "Microsoft YaHei";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=KaiTi]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=KaiTi]::before {
  content: "楷体";
  font-family: "KaiTi";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=FangSong]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=FangSong]::before {
  content: "仿宋";
  font-family: "FangSong";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=Arial]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=Arial]::before {
  content: "Arial";
  font-family: "Arial";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=Times-New-Roman]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=Times-New-Roman]::before {
  content: "Times New Roman";
  font-family: "Times New Roman";
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value=sans-serif]::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value=sans-serif]::before {
  content: "sans-serif";
  font-family: "sans-serif";
}

.ql-font-SimSun {
  font-family: "SimSun";
}

.ql-font-SimHei {
  font-family: "SimHei";
}

.ql-font-Microsoft-YaHei {
  font-family: "Microsoft YaHei";
}

.ql-font-KaiTi {
  font-family: "KaiTi";
}

.ql-font-FangSong {
  font-family: "FangSong";
}

.ql-font-Arial {
  font-family: "Arial";
}

.ql-font-Times-New-Roman {
  font-family: "Times New Roman";
}

.ql-font-sans-serif {
  font-family: "sans-serif";
}

第三步：就是创建MessageTemplateConfig.vue组件代码了，标红的为代码优化部分，橘色的模板内容就是最简单的富文本编辑器代码了，模板名称，邮件标题什么的都是自己定义的，想要什么加什么就行，我这是发送邮件的一个模板。表单验证的那部分代码可以解开的，我没用所以注释掉了。

<template>
  <div >
    <el-row class="warp">
      <!--
      Form 组件提供了表单验证的功能，只需要通过 rule 属性传入约定的验证规则，并 Form-Item 的 prop 属性设置为需校验的字段名即可。具体可以参考官网：http://element.eleme.io/#/zh-CN/component/form
      -->
      <el-col :span="24" class="warp-main">
        <el-form ref="infoForm" :model="messageTemplate" :rules="rules" label-width="120px">
          <el-form-item label="模板名称" prop="a_title">
            <el-input v-model="messageTemplate.template_name"></el-input>
          </el-form-item>
          <el-form-item label="邮件标题">
            <el-input v-model="messageTemplate.email_title"></el-input>
          </el-form-item>
          <el-form-item label="抄送人">
            <el-checkbox-group v-model="checkList">
              <el-checkbox label="工单创建人"></el-checkbox>
              <el-checkbox label="防火墙小组"></el-checkbox>
            </el-checkbox-group>
          </el-form-item>
          <el-form-item label="发送工单信息" >
              <el-button class="tag-read" type="success" size="mini" data-clipboard-text="RQ申请人姓名" @click="copy">RQ申请人姓名</el-button>
              <el-button class="tag-read" type="success" size="mini" data-clipboard-text="RQ申请人工号" @click="copy">RQ申请人工号</el-button>
              <el-button class="tag-read" type="success" size="mini" data-clipboard-text="RQ工单号" @click="copy">RQ工单号</el-button>
              <el-button class="tag-read" type="success" size="mini" data-clipboard-text="创建人姓名" @click="copy">创建人姓名</el-button>

              <el-button class="tag-read" type="success" size="mini" data-clipboard-text="执行时间" @click="copy">执行时间</el-button>
              <el-button class="tag-read" type="success" size="mini" data-clipboard-text="创建人邮箱" @click="copy">创建人邮箱</el-button>
          </el-form-item>
          <el-form-item label="模板内容">

<style scoped>
</style>

第四步：创建一个MessageTemplate.vue文件使用MessageTemplateConfig.vue这个组件

<template>
  <div>
    <el-dialog title="模板管理" :visible.sync="menuVisible" width="60%">
　　　　//调用组件的方式 并绑定值 进行组件间的传值
      <MessageTemplateConfig :messageTemplate = this.table.messageTemplate></MessageTemplateConfig>
    </el-dialog>
    <DialogPanel
      @ok="doUpdate"
      @cancel="cancel"
      title="修改角色"
      :status="updateDialogStatus"
      :list="updateCols"
      width="90%"
    ></DialogPanel>
    <div class="table-top">
      <el-row>

          placeholder="[模板名称]"
          size="mini"
          style="width:300px;margin-right:5px;"
        ></el-input>

            type="primary"
            circle

        <el-tooltip
          class="item"

          content="添加模板"
          placement="top"
        >

            circle

      </el-table-column>
    </el-table>
    <!--<div class="fw-page">

以上步骤以及代码中的提示就可以实现简单的富文本编辑器了。

接下来说一下组件传值，在第三步和第四步之间用到了组件传值，代码中都有标注，接下来拿出来重点说一下：

第四步的使用组件代码：标红处为传递到组件的值。

<el-dialog title="模板管理" :visible.sync="menuVisible" width="60%">
      <MessageTemplateConfig :messageTemplate = this.table.messageTemplate></MessageTemplateConfig>
</el-dialog>

第三步组件接收到传递过来的值，并进行处理：此段代码删除了一部分，主要展示接收值，并进行处理，完整代码看上面第三步代码即可。

data() {
      return {
        checkList: [],
      }
    },
    props:["messageTemplate"],  //通过props这个属性获取传递过来的值
    watch:{ 　　　　　　　　　　　　//在通过watch监听这个值的变化，将值赋给组件中的一个属性  这里需要注意的是 一定要确定这两个值是否是同一类型 不然不会生效哟 有时候即使看上去格式一模一样 但是就是不生效 这时候就要确认一下 两个值是否是同一类型　　　　　　　　　　　　
      messageTemplate: function(a,b){  //a是新值 b是旧值
        if (a.email_sender_name != ""){
          this.checkList = eval(a.email_sender_name)
        }
      }
    },
