Vue页面内公共的多类型附件图片上传区域并适用折叠面板(示例代码)

在前端项目中,附件上传是很常用的功能,几乎所有的app相关项目中都会使用到,一般在选择使用某个前端UI框架时,可以查找其内封装好的图片上传组件,但某些情况下可能并不适用于自身的项目需求,本文中实现的附件上传区域支持超多类型附件分类型上传,并且可根据特定条件具体展示某些类型的附件上传,本文中是直接摘自具体的页面,后面会抽时间单独封装出来一个附件上传的组件。

一、Vue页面内附件展示区域代码

<div class="retuinfo">
          <div class="theadInfo-headline">
            <span></span>
            {{FileDivName}}
          </div>
          <Collapse v-model="defaultCollapse">
            <Panel v-for="(item,pngIndex) in pngFileArray" v-bind:key="pngIndex" :name="item.num" v-show="item.isshow">
              {{item.name}}
              <div class="obsfilesdiv" slot="content">
                <div v-for="(obs,index) in item.files" v-bind:key="index" class="obsfileslist">
                  <input ref="fileImg" type="file" accept="image/*;capture=camera" style="display: none;"
                    @change="setObsFile(item.num,1,obs.FileType,obs.Num,obs.Code)">
                  <label style="color:#6d7180; font-size: 20px;">{{obs.FileType}}<span style="color:red;"
                      v-show="obs.FileType!="其他"">*</span></label>
                  <ul class="obsfilesul">
                    <li v-for="(objitem,objindex) in obs.FileObj" v-bind:key="objindex">
                      <img :src="objitem.imgurl ? objitem.imgurl : fileUrl"
                        @click="showObsFiles(obs.FileFlag,objitem.imgurl)" />
                      <img src="../../../img/other/wrong.png" v-show="objitem.IsCanEdit" class="wrong_class"
                        @click="deleteObsFlie(item.num,index,objindex,objitem.imgid,objitem.imgurl)" />
                    </li>
                    <li style="border: 4px solid #f3f3f3;" @click="PlusClick(obs.FileType,obs.FileFlag,obs.Num)">
                      <img src="../../../img/icon-adds.png" alt="" />
                    </li>
                    <div style="clear:both;"></div>
                  </ul>
                </div>
              </div>
            </Panel>
          </Collapse>
        </div>
        <div class="modal" v-show="viewBigImg">
            <div class="img-view-modal" style="text-align: right;">
                <img :src="viewImgURL" style="width: 100%;" @click="hideShow(0)">
                <Icon type="md-close" style="margin-right: 20px;" size="20" @click="hideShow(0)" />
            </div>
        </div>
      </div>

Vue项目引入了以下UI框架:(若想拿来即用 需要先在main.js中引入)IView、MintUI、Vant 此段代码只要确保引入IView即可正常使用

二、数据绑定设计

具体的不详细展开说,数组与通过属性控制,很好理解。

pngFileArray: [{
            num: "0",
            name: "整车",
            isshow: localStorage.getItem("RoleName").indexOf("铭牌质检员") != -1 ? true : false,
            files: [ //FileFlag://1:图片;2:视频  3.其他
              {
                FileType: "整车铭牌图片",
                Code: "201",
                Num: 0,
                FileFlag: 1,
                FileObj: [],
                IsNoFile: true
              },
              {
                FileType: "车架VIN图片",
                Code: "207",
                Num: 1,
                FileFlag: 1,
                FileObj: [],
                IsNoFile: true
              },
              {
                FileType: "终端图片",
                Code: "301",
                Num: 2,
                FileFlag: 1,
                FileObj: [],
                IsNoFile: true
              }
            ]
          },
          {
            num: "1",
            name: "里程",
            isshow: localStorage.getItem("RoleName").indexOf("客户经理") != -1 ? true : false,
            files: [{
                FileType: "里程表照片",
                Code: "701",
                Num: 3,
                FileFlag: 1,
                FileObj: [],
                IsNoFile: true
              }
            ]
          }
        ],

三、绑定的方法

1.图片加载方法:

//获取图片列表
      getImageList() {
        this.$indicator.open({
          text: "图片加载中...",
          spinnerType: "snake"
        });
        let _this = this;
        let downRequest ={
            "crm_vin": this.parms.crm_vin,
            "crm_vehiclenumber": this.parms.crm_vehiclenumber
          };
        let imgListParams = {
          "ImageDownRequest": JSON.stringify(downRequest),
          "username": localStorage.getItem("usernameone"),
          "password": localStorage.getItem("password")
        };
        console.log("获取图片列表参数:", imgListParams);
        _this.$ajax.defaults.headers["Content-Type"] = "application/x-www-form-urlencoded;"; //配置请求头
        this.$ajax.post(this.imageListUrl, this.$qs.stringify(imgListParams)).then(resdata => {
          _this.$indicator.close();
          console.log("获取到的图片列表数据:", resdata);
          let data = resdata.data;
          console.log("转换后的图片列表数据:", data);
          if (resdata.status != 200) {
            _this.$toast({
              message: "获取图片列表失败!",
              duration: 3000
            });
            return;
          }
          //先清空原有的图片列表
          _this.pngFileArray.forEach((rr,index,array) =>{
            for(var file=0;file<rr.files.length;file++){
              _this.pngFileArray[index].files[file].FileObj = [];
              _this.pngFileArray[index].files[file].IsNoFile = true;
            }
          });
          //将图片列表写入页面各图片分类区域
          for(var i=0;i<data.length;i++){
            _this.pngFileArray.forEach((rr,index,array) =>{
              for(var file=0;file<rr.files.length;file++){
                if(data[i].crm_imagetypeno==rr.files[file].Code){
                  let putparm = {
                    "IsCanEdit":false,
                    "imgid": data[i].crm_careimageId,
                    "imgurl": data[i].ImageUrl
                  };
                  _this.pngFileArray[index].files[file].FileObj.push(putparm);
                  _this.pngFileArray[index].files[file].IsNoFile = false;
                }
              }
            });

          }
        }).catch(function(error) {
          _this.$indicator.close();
          _this.$toast({
            message: error,
            duration: 3000
          });
        });
      },

2.图片展示方法

showObsFiles(type, url) { //展示图片或视频
        console.log("展示附件:" + type);
        if (type == 1) { //图片
          this.viewBigImg = true;
          this.viewImgURL = url;
        } else { //文件
          this.$messagebox.alert("不支持查看文件,请到PC端操作!", "提示");
          return;
        }
      },

3.上传图片相关方法

(最开始设计的是支持图片、视频和其他类型文件等上传,项目中已实现,本文中不做拓展)

PlusClick(type, flag, num) {
        console.log("当前附件类型:" + type);
        console.log("当前附件序号:" + num);
        this.currentFileType = type;
        if (flag == 1) { // 图片上传
          this.$refs.fileImg[num].dispatchEvent(new MouseEvent("click"));
        } else if (flag == 2) { // 视频上传
          this.$refs.fileVideo[num].dispatchEvent(new MouseEvent("click"));
        } else { // 其他类型文件
          this.$refs.filElem[num].dispatchEvent(new MouseEvent("click"));
        }
      },
setObsFile(classify, type, obsFileType, num, code) { //保存图片到crm中
        var _this = this;
        var inputFile; //文件流
        console.log("图片大分类:" + classify + " " + obsFileType + " " + num) + " 图片编码:" + code;
        if (type == 1) {
          inputFile = this.$refs.fileImg[num].files[0];
          this.$refs.fileImg[num].value = "";
        }
        var fileName = inputFile.name;
        if (!inputFile) {
          return;
        }
        if (inputFile.type == "image/jpg" || inputFile.type == "image/jpeg" || inputFile.type == "image/png" ||
          inputFile.type ==
          "image/gif") {} else {
          this.$messagebox.alert("请上传图片", "提示");
          return;
        }
        _this.$indicator.open({
          text: "文件上传中,请稍候...",
          spinnerType: "snake"
        });
        //图片压缩与转换成base64文件流
        var reader = new FileReader();
        reader.readAsDataURL(inputFile);
        reader.onloadend = function(e) {
          let result = this.result;
          console.log("********未压缩前的图片大小******** :" + result.length / 1024)
          _this.pulic.dealImage(result, {}, function(base64) {
            console.log("********压缩后的图片大小******** :" + base64.length / 1024)
            _this.putObsFile(classify, fileName, base64, obsFileType, code);
          });
          //reader.result.substring(this.result.indexOf(",")+1);
          // "data:image/png;base64,"+reader.result
        }
      },
      putObsFile(classify, fileName, base64, obsFileType, code) { //抽出公共上传图片文件方法
        var _this = this;
        let usernameone = this.$Base64.encode("administrator");
        let password = this.$Base64.encode("pass@word1");
        let parmsImages = {
          crm_newenergyid: localStorage.getItem("crm_newenergyid"),
          vin: _this.parms.crm_vin,
          crm_vehiclenumber: _this.parms.crm_vehiclenumber,
          CareType: code,
          CreateBy: localStorage.getItem("SystemUserId"),
          ImageStr: base64.split(",")[1],
          username: usernameone,
          password: password
        }
        let parms = {
          ImageMessage: JSON.stringify(parmsImages)
        }
        console.log(JSON.stringify(parmsImages));
        console.log(JSON.stringify(parms));
        _this.$ajax.defaults.headers["Content-Type"] = "application/x-www-form-urlencoded;"; //配置请求头
        _this.$ajax.post(_this.imageSaveUrl, _this.$qs.stringify(parms))
          .then(resdata => {
            _this.$indicator.close();
            console.log("接口响应数据:", resdata);
            let data = resdata.data;
            console.log("转换后的响应数据:", data);
            if (resdata.status != 200) {
              _this.$toast({
                message: "保存失败!接口调用异常",
                duration: 3000
              });
              return;
            }
            //将上传成功后的图片url回写到页面的图片分类url中
            console.log("当前分类下的所有图片类型:" + JSON.stringify(_this.pngFileArray[parseInt(classify)].files));
            for (var i = 0; i < _this.pngFileArray[parseInt(classify)].files.length; i++) { //遍历当前分类下的图片类型数组  并赋值后台返回的数据
              if (obsFileType == _this.pngFileArray[parseInt(classify)].files[i].FileType) {
                //设置图片文件路径等 putparm
                let putparm = {
                  "IsCanEdit":true,
                  "imgid": data.crm_careimageId,
                  "imgurl": data.ImageUrl
                };
                _this.pngFileArray[parseInt(classify)].files[i].FileObj.push(putparm);
                _this.pngFileArray[parseInt(classify)].files[i].IsNoFile = false;
              }
            }
            _this.$messagebox.alert("附件上传成功", "提示");
          }).catch(err => {
            console.log(JSON.stringify(err));
            _this.$toast({
              message: "上传失败",
              duration: 1500
            });
            _this.$indicator.close();
          });
      },

4.删除图片方法

(本文中是只有未提交的图片可删除,若已提交过的图片即页面初始加载获取到的图片不可以删除)

deleteObsFlie(classify,num,index,id,url) { //删除附件
        var _this = this;
        this.$messagebox.confirm("确定删除该图片吗?", "确认").then(action => {
          var del_param = {
            "id": id,
            "url": url
          };
          _this.$indicator.open({
            text: "删除图片中,请稍候...",
            spinnerType: "snake"
          });
          _this.$ajax.defaults.headers["Content-Type"] = "application/x-www-form-urlencoded;"; //配置请求头
          _this.PromiseCall(_this.DelImgFilesURL, _this.$qs.stringify(del_param))
            .then(data => {
              _this.$indicator.close();
              console.log(JSON.stringify(data));
              if (data.status != 200) {
               _this.$messagebox.alert("删除图片失败", "提示");
               return;
              }
              _this.pngFileArray[parseInt(classify)].files[num].FileObj.splice(index, 1);
              _this.$toast({
                message: "删除图片成功",
                duration: 1500
              });
            }).catch(err => {
              _this.doCatch(err);
              _this.$toast({
                message: "删除图片失败"+err,
                duration: 1500
              });
              _this.$indicator.close();
            });
        });
      },
