自定义input组件实现拖拽文件上传

vue部分

复制
<tag-input
 id="uploadTag"
 ref="uploadTag"
 v-model="fileNameList"
 size="small"
 @input="removeFile"
></tag-input>

逻辑部分

页面加载时监听拖拽事件，监听后将文件放置下发fileList参数列表中

复制
  mounted() {
    setTimeout(() => {
      this.$nextTick(() => {
        if (this.$refs.uploadTag) {
          let dropEle = this.$refs.uploadTag.$el
 
          // 禁止拖拽文件后打开文件
          dropEle.addEventListener('drop', e => {
            e.preventDefault();
            e.stopPropagation();
          }, false)
 
          dropEle.addEventListener('dragover', e => {
            e.preventDefault();
            e.stopPropagation();
          }, false)
 
          dropEle.addEventListener('dragleave', e => {
            e.preventDefault();
            e.stopPropagation();
          }, false)
 
          // 处理拖拽文件的逻辑
          dropEle.addEventListener('drop', e => this.watchFileUpload(e))
        }
      })
    },)
  }
  // 拖拽上传
  private watchFileUpload(e) {
    e.preventDefault();
    e.stopPropagation();
 
    var df = e.dataTransfer;
    var dropFiles = []; // 拖拽的文件，会放到这里
    var dealFileCnt =; // 读取文件是个异步的过程，需要记录处理了多少个文件了
    var allFileLen = df.files.length; // 所有的文件的数量，给非Chrome浏览器使用的变量
 
    // 检测是否已经把所有的文件都遍历过了
    function checkDropFinish() {
      dealFileCnt++;
    }
 
    if (df.items !== undefined) {
      // Chrome拖拽文件逻辑
      for (var i =; i < df.items.length; i++) {
        var item = df.items[i];
        if (item.kind === "file" && item.webkitGetAsEntry().isFile) {
          var file = item.getAsFile();
          dropFiles.push(file);
        }
      }
    } else {
      // 非Chrome拖拽文件逻辑
      for (var i =; i < allFileLen; i++) {
        var dropFile = df.files[i];
        if (dropFile.type) {
          dropFiles.push(dropFile);
          checkDropFinish();
        } else {
          try {
            var fileReader = new FileReader();
            fileReader.readAsDataURL(dropFile.slice(, 3));
 
            fileReader.addEventListener('load', function (e) {
              console.log(e, 'load');
              dropFiles.push(dropFile);
              checkDropFinish();
            }, false);
 
            fileReader.addEventListener('error', function (e) {
              console.log(e, 'error，不可以上传文件夹');
              checkDropFinish();
            }, false);
 
          } catch (e) {
            console.log(e, 'catch error，不可以上传文件夹');
            checkDropFinish();
          }
        }
      }
    }
    dropFiles.forEach(item => {
      this.fileList.push(item)
    })
    this.fileNameList = this.fileList.map(item => {
      if (item.name) {
        return item.name
      }
      if (item.fileName) {
        return item.fileName
      }
    });
  }

删除当前文件

复制
  // 附件删除 下拉框
  private removeFile(nameList, name) {
    // 记录删除的附件信息
    this.fileList.splice(this.fileList.findIndex(item => item.fileName === name || item.name === name),)
    this.fileNameList = this.fileList.map(item => item.name || item.fileName);
  }

封装的tag-input组件

复制
<template>
  <div
    class="yh-input-tag input-tag-wrapper"
    ref="InputTag"
    @click="foucusTagInput"
  >
    <el-tag
      v-for="(tag, idx) in innerTags"
      :key="tag"
      :size="size"
      :closable="!readonly"
      :disable-transitions="false"
      @close="remove(tag, idx)"
      >{{ tag }}</el-tag
    >
    <input
      :readonly="readonly || readonlyIpt"
      class="tag-input"
      :class="[size ? 'yh-input-tag--' + size : '']"
      :style="widthStyle"
      :placeholder="isplaceholder"
      v-model="newTag"
      @keydown.delete.stop="removeLastTag"
      @keydown="addNew"
      @blur="blurTagInput"
    />
  </div>
</template>
 
<script>

最后实现的效果

可支持手动拖拽上传 

多图上传组件vue

小编参加的第一个项目，就遇到了麻烦的多图上传，通过多天的努力，写出了一个多图的组件，希望可以帮助到大家

组件template部分

多图上传按钮+多图上传弹窗+图片上的预览删除图标

复制
<template>
<div>
    <div class="many">
      <el-form-item>
        <div class="upload-item">
          <el-button type="primary" @click="uploadFile">多图上传</el-button>
        </div>
      </el-form-item>
    </div>
 
  <el-dialog title="图片预览" :visible.sync="dialogImgVisible" width="%">
    <img :src="dialogImageUrl" alt="" class="previewImg" />
  </el-dialog>
 
 
  <!--多图上传弹窗界面-->
<el-dialog :title="'上传'" :visible.sync="dialogFormVisible" custom-class="pub_dialog" >
  <el-form style="width:px;height: 380px">
    <!--内容部分  -->
    <el-form-item><!---->
        <div style="display: flex;justify-content: center">
          <label>选择文件：</label>
          <div>
            <div class="desc">支持 jpg, png 图片格式，且不超过kb</div>
            <el-upload
                :action="UPLOAD_URL"
                :headers="authorToken"
                :auto-upload="true"
                accept="image/jpg,image/png,image/jpeg"
                :on-success="handleSuccess"
                :before-upload="handleBeforeUpload"
                :show-file-list="false"
                multiple
                :limit=""
                :on-exceed="handleExceed"
                :file-list="fileList">
              <el-button size="small" type="primary">上传图片</el-button>
            </el-upload>
          </div>
        </div>
 
          <div class="fileList" style="margin-top:px;display: flex;flex-wrap: wrap;">
            <div class="item" v-for="(item,index) in images" :key="index">
              <img :src="item.url" alt="" :key="index" style=" width:%;height: 100%" class = "imgList">
              <div class="scissor-icon">
                <i class="el-icon-scissors" @click="changeFile(item)"></i>
              </div>
              <div class="delete-icon">
                <i class="el-icon-delete" @click="handleRemove(item)"></i>
              </div>
              <div class="search-icon">
                <i class="el-icon-search" @click="handlePreview(item)"></i>
              </div>
              <el-input
                  type="textarea"
                  :autosize="{ minRows:, maxRows: 7}"
                  placeholder="请输入图片描述"
                  v-model="item.manyDescription"
                  :key="index"
                  style=" width:%;height: 100%;margin-left: 10px">
              </el-input>
            </div>
          </div>
    </el-form-item>
  </el-form>
  <div slot="footer" class="dialog-footer">
    <el-button @click="dialogFormVisible = false">取 消</el-button>
    <el-button type="primary" @click="closeDialog">确 定</el-button>
  </div>
</el-dialog>
</div>
</template>

组件script部分

1.变量数据区域

代码如下（示例）：

复制
<script>
export default {
  name: "UploadMany",
  data() {
    return {
      textarea:'',
      dialogImageUrl: '',
      dialogImgVisible: false,
      dialogVisible: false,
      fileList: [],
      imgs: [],
      images: [],
      UPLOAD_URL: "/v/admin/common/upload",//这里填写你的后端上传接口地址
      authorToken: {
        Authorization: 'Bearer ' + sessionStorage.getItem("token"),
        siteId:sessionStorage.getItem("siteId")
      },
      param: {
        token: ''
      },
      fileNum:,
      num:,
      dialogFormVisible: false,//添加表单弹出框是否显示
      dialogChangeVisible: false,
      picsList: [],  //页面显示的数组
      // 防止重复提交
      loading: true,
    }
  },

2.方法区域

代码如下（示例）：

复制
methods: {
	//删除方法
    handleRemove(file) {
      console.log(file)
      //.获取将要删除的图片的临时路径
      const filePath = file.url
      //.从数组中，找到这个图片对应的索引值
      const i = this.imgs.findIndex((x) => x.url === filePath)
      //.调用数组的 splice 方法，把图片信息对象，从 pics 数组中移除
      this.imgs.splice(i,)
      console.log(this.imgs)
    },
    //预览方法
    handlePreview(file) {
      console.log(file);
      this.dialogImageUrl = file.url;
      this.dialogImgVisible = true;
    },
    //限制上传文件个数
    handleExceed(files, fileList) {
      this.$message.warning(`当前限制选择 个文件，本次选择了 ${files.length} 个文件，共选择了 ${files.length + fileList.length} 个文件`);
    },
    //上传成功后
    handleSuccess(response, fileList) {
      console.log(response);
      console.log(fileList)
      this.loading = false
      if(response.code ===){
        this.imgs.push({name: response.data.resourceName, url: response.data.resourceUrl, manyDescription: '', manyResourceId: response.data.id})
        this.num++;
        if(this.num == this.fileNum){
          for(let i =; i < this.num ; i++){
            this.$emit('getManyImg', this.imgs[i])
          }
          this.num =;
          this.fileNum =;
          this.images = this.imgs;
          this.imgs = [];
        }
      }else{
        this.$message.error('上传失败');
      }
    },
    
    handleBeforeUpload(file) {
      // 这里做可以做文件校验操作
      const isImg = /^image\/\w+$/i.test(file.type)
      if (!isImg && this.fileType == 'image/*') {
        this.$message.error('只能上传 JPG、PNG、GIF 格式!')
        return false
      }
      this.fileNum++;
    },
 
    uploadFile(){
      this.dialogFormVisible = true;
      this.loading = false;
    },
    
    closeDialog(){
      this.dialogFormVisible = false;
      this.imgs = [];
      this.images = [];
    }
 
  }
}

组件使用

1.在你需要用到的界面vue里导入组件

复制
import UploadMany from '@/components/upload/UploadMany';
import {getToken} from '@/utils/auth';
export default {
  name: "TestEditor",
  components: {
    UploadMany,
  },

2.template部分使用组件

复制
    <el-col :span="">
      <el-form-item prop="manyImg" label="多图上传：" :label-width="imgWidth" class="form">
        <upload-many v-model="dialogForm.manyImg" @getManyImg="getManyImg" ></upload-many>
        <div class="fileList" style="margin-top:px;display: flex;flex-wrap: wrap;">
          <div class="item" v-for="(itemPhoto,indexPhoto) in dialogForm.images" :key="indexPhoto">
            <div class="item-left" style="position: relative">
              <img :src="itemPhoto.url" alt="" :key="indexPhoto" class = "imgList">
             <div class="item-bottom">
               <div class="search-icon">
                 <i class="el-icon-search" @click="handlePreview(itemPhoto)"></i>
               </div>
               <div class="delete-icon">
                 <i class="el-icon-delete" @click="handleRemove(itemPhoto)"></i>
               </div>
             </div>
            </div>
            <el-input
                type="textarea"
                :autosize="{ minRows:, maxRows: 7}"
                placeholder="请输入图片描述"
                v-model="itemPhoto.manyDescription"
                style=" width:%;height: 100%;margin-left: 10px">
            </el-input>
          </div>
        </div>
      </el-form-item>
    </el-col>

3.方法部分

复制
getManyImg(imgs) {
  this.dialogForm.images.push(imgs);
  console.log(this.dialogForm.images)
},
    handleRemove(file) {
  console.log(file)
  //.获取将要删除的图片的临时路径
  const filePath = file.url
  //.从数组中，找到这个图片对应的索引值
  const i = this.dialogForm.images.findIndex((x) => x.url === filePath)
  //.调用数组的 splice 方法，把图片信息对象，从 pics 数组中移除
  this.dialogForm.images.splice(i,)
},
//预览图片
handlePreview(file) {
  console.log(file);
  this.dialogImageUrl = file.url;
  this.dialogImgVisible = true;
},

组件完整代码（含裁剪组件，不需要请手动删除）

复制
<template>
<div>
    <div class="many">
