用element 做一个图片上传，我想要限制只能上传一张图片但是 limit=1 貌似不起作用

Question

<el-upload

    class="upload-demo" list-type="picture"
    action="https://api.doudot.cn/api/Attachment/upload"
    :on-success="posterSuccess"
    :show-file-list="true"
    :limit=1 //看到网上有人这样用，我拿过来不起作用
    :on-preview="posterPreview">
    <el-button size="small" type="primary" class="up-btn">点击上传</el-button>
    <div slot="tip" class="el-upload__tip" show-file-list="false">只能上传jpg/png文件，且不超过500kb</div>
  </el-upload>

Answer 1

是不是你的:limit="1" 写成了:limit=1
