<-form-item label="上传库房布局图片" prop="picUrl">
<el-upload
class="avatar-uploader"
accept="image/*"
:headers="headers"
:action="minioUploadApi"
:show-file-list="false"
:on-success="handleAvatarSuccessUpdate"
:before-upload="beforeAvatarUpload"
:limit="1"
:on-remove="(file, fileList)=>picsRemove('1', file, fileList)"
>
<img v-if="imageUrl" :src="formUpdate.picUrl" class="avatar">
<i v-else class="el-icon-plus avatar-uploader-icon" />
</el-upload>
</el-form-item>

上述代码将限制用户只能上传单张图片，并且可以使用新上传的图片覆盖之前的图片。

可以使用以下代码布局：

<template>
  <el-card shadow="never">
    <el-divider content-position="left">
      <h3>创建&编辑邮件模板</h3>
    </el-divider>
    <el-form label-position="top">
      <el-form-item label="邮件名称" prop="name">
        <el-input v-model="modeData.name" style="width: 200px" />
      </el-form-item>
      <el-form-item label="模板名称" prop="subject">
        <el-input v-model="modeData.subject" style="width: 200px" />
      </el-form-item>
      <el-form-item label="语言" prop="language">
        <el-select v-model="modeData.language" placeholder="请选择">
          <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value" />
        </el-select>
      </el-form-item>
      <el-form-item label="启动/禁用" prop="enable">
        <el-switch v-model="modeData.enable" active-text="禁用" inactive-text="启动" />
      </el-form-item>
      <el-form-item label="模板配置" prop="value">
        <PiEditor v-model="modeData.value" placeholder="请输入" :height="400" />
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="onSubmit">保存</el-button>
      </el-form-item>
    </el-form>
  </el-card>
</template>

这样可以使表单更加美观，且易于使用。

<el-form-item :label="$t('config.forwardPart')" prop="sendPart"> <template #label> <span>全部转发</span> </template> <el-radio-group v-model="analysisState.formData.sendPart" class="w-320"> <el-radio label="Y">是</el-radio> <el-radio label="N">否</el-radio> </el-radio-group> </el-form-item> <el-form-item :label="'日志源IP'" prop="serverIp"> <el-input class="w-320" v-model="analysisState.formData.sourceIp" placeholder="请输入日志源IP" clearable /> </el-form-item> 当上面选是时 隐藏日志源ip怎么做到

您可以通过在 `el-form-item` 元素上绑定 `v-if` 或 `v-show` 指令来实现当选中“是”时隐藏“日志源IP”输入框的效果。示例代码如下：

<el-form-item :label="$t('config.forwardPart')" prop="sendPart">
  <template #label>
    <span>全部转发</span>
  </template>
  <el-radio-group v-model="analysisState.formData.sendPart" class="w-320">
    <el-radio label="Y">是</el-radio>
    <el-radio label="N">否</el-radio>
  </el-radio-group>
</el-form-item>
<el-form-item :label="'日志源IP'" prop="serverIp" v-if="analysisState.formData.sendPart === 'N'">
  <el-input class="w-320" v-model="analysisState.formData.sourceIp" placeholder="请输入日志源IP" clearable />
</el-form-item>

在这个示例中，我们在“日志源IP”输入框的 `el-form-item` 元素上绑定了 `v-if` 指令，判断 `analysisState.formData.sendPart` 是否等于 `N`，如果是则显示该输入框，否则隐藏该输入框。
