用户头像上传

使用 before-upload 限制用户上传的图片格式和大小。

<fx-upload
  class="avatar-uploader"
  :max-size="maxSize"
  :show-file-list="showFileList"
  :on-success="handleAvatarSuccess"
  :on-error="handleAvatarError"
  :before-upload="beforeAvatarUpload"
>
  <img v-if="imageUrl" :src="imageUrl" class="avatar" />
  <i v-else class="el-icon-plus avatar-uploader-icon"></i>
  <div slot="tip" class="el-upload__tip" v-if="maxSize">只能上传图片文件，且不超过{{maxSize}}kb</div>
</fx-upload>

<script>
  export default {
    data() {
      return {
        imageUrl: '',
        showFileList:false,
        maxSize:20
      };
    },
    methods: {
      handleAvatarSuccess(res, file) {
        console.log('handleAvatarSuccess...',res,file)
        this.imageUrl = URL.createObjectURL(file.raw);
      },
      handleAvatarError(err,file){
        console.log('handleAvatarError...',err,file)
        this.imageUrl = URL.createObjectURL(file.raw);
      },
      beforeAvatarUpload(files) {
        const file=files[0];
        const isJPG = file.type === 'image/jpeg';
        const isLt2M = file.size / 1024 / 1024 < 2;

        if (!isJPG) {
          this.$message.error('上传头像图片只能是 JPG 格式!');
        }
        if (!isLt2M) {
          this.$message.error('上传头像图片大小不能超过 2MB!');
        }
        return isJPG && isLt2M;
      },
    },
  };
</script>

<style>
  .avatar-uploader .el-upload {
    border: 1px solid #d9d9d9;
    border-radius: 6px;
    cursor: pointer;
    position: relative;
    overflow: hidden;
  }
  .avatar-uploader .el-upload:hover {
    border-color: #409eff;
  }
  .avatar-uploader-icon {
    font-size: 28px;
    color: #8c939d;
    width: 70px;
    height: 70px;
    line-height: 70px;
    text-align: center;
  }
  .avatar {
    width: 70px;
    height: 70px;
    display: block;
  }
</style>

照片墙

使用 list-type 属性来设置文件列表的样式。

<fx-upload
  url="https://jsonplaceholder.typicode.com/posts/"
  list-type="picture-card"
  :on-preview="handlePictureCardPreview"
  :on-remove="handleRemove">
  <i class="el-icon-plus"></i>
</fx-upload>
<fx-dialog :visible.sync="dialogVisible">
  <img width="100%" :src="dialogImageUrl" alt="">
</fx-dialog>
<script>
  export default {
    data() {
      return {
        dialogImageUrl: '',
        dialogVisible: false
      };
    },
    methods: {
      handleRemove(file, fileList) {
        console.log(file, fileList);
      },
      handlePictureCardPreview(file) {
        this.dialogImageUrl = file.url;
        this.dialogVisible = true;
      }
    }
  }
</script>

文件缩略图

使用 scoped-slot 去设置缩略图模版。

<fx-upload
  url="#"
  list-type="picture-card"
  :auto-upload="false">
    <i slot="default" class="el-icon-plus"></i>
    <div slot="file" slot-scope="{file}">
      <img
        class="el-upload-list__item-thumbnail"
        :src="file.url" alt=""
      >
      <span class="el-upload-list__item-actions">
        <span
          class="el-upload-list__item-preview"
          @click="handlePictureCardPreview(file)"
        >
          <i class="el-icon-zoom-in"></i>
        </span>
        <span
          v-if="!disabled"
          class="el-upload-list__item-delete"
          @click="handleRemove(file)"
        >
          <i class="el-icon-delete"></i>
        </span>
      </span>
    </div>
</fx-upload>
<fx-dialog :visible.sync="dialogVisible">
  <img width="100%" :src="dialogImageUrl" alt="">
</fx-dialog>
<script>
  export default {
    data() {
      return {
        dialogImageUrl: '',
        dialogVisible: false,
        disabled: false
      };
    },
    methods: {
      handleRemove(file) {
        console.log(file);
      },
      handlePictureCardPreview(file) {
        this.dialogImageUrl = file.url;
        this.dialogVisible = true;
      },
      handleDownload(file) {
        console.log(file);
      }
    }
  }
</script>

图片列表缩略图

<fx-upload
  class="upload-demo"
  url="https://jsonplaceholder.typicode.com/posts/"

  list-type="picture">
  <fx-button size="small" type="primary">点击上传</fx-button>
  <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
</fx-upload>
<script>
  export default {
    data() {
      return {
        fileList: [{name: 'food.jpeg', url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100'}, {name: 'food2.jpeg', url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100'}]
      };
    },
    methods: {
      handleRemove(file, fileList) {
        console.log(file, fileList);
      },
      handlePreview(file) {
        console.log(file);
      }
    }
  }
</script>

上传文件列表控制

通过 on-change 钩子函数来对列表进行控制

<fx-upload
  class="upload-demo"
  url="https://jsonplaceholder.typicode.com/posts/"
  :on-change="handleChange"
  :file-list="fileList">
  <fx-button size="small" type="primary">点击上传</fx-button>
  <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
</fx-upload>
<script>
  export default {
    data() {
      return {
        fileList: [{
          name: 'food.jpeg',
          url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100'
        }, {
          name: 'food2.jpeg',
          url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100'
        }]
      };
    },
    methods: {
      handleChange(file, fileList) {
        this.fileList = fileList.slice(-3);
      }
    }
  }
</script>
