element-admin的Tinymce富文本,上传图片改成本地处理

html

<el-upload :multiple="true" :file-list="fileList" :show-file-list="true"
   :on-remove="handleRemove" :on-success="handleSuccess" :before-upload="beforeUpload" :headers="tokenHeader"
   class="editor-slide-upload" action="#" list-type="picture-card">
   <el-button size="small" type="primary">点击上传</el-button>
</el-upload>

　　

 

 

js 主要是在 :before-upload里面处理

 1 beforeUpload(file) {
 2             this.getBase64(file).then(res => {
 3                 this.fileBase64 = res
 4             })
 5             const _self = this;
 6             const _URL = window.URL || window.webkitURL;
 7             const fileName = file.uid;
 8             this.listObj[fileName] = {};
 9             return new Promise((resolve, reject) => {
10                 const img = new Image();
11                 img.src = _URL.createObjectURL(file);
12                 img.onload = function () {
13                     _self.listObj[fileName] = {
14                         hasSuccess: true,
15                         uid: file.uid,
16                         width: this.width,
17                         height: this.height,
18                         url: _self.fileBase64
19                     };
20                     _self.fileList.push({
21                         url:_self.fileBase64,
22                         uid:file.uid
23                     })
24                 };
25                 resolve(false);
26             });
27         },
28         getBase64(file) {
29             return new Promise(function(resolve, reject) {
30                 let reader = new FileReader();
31                 let imgResult = "";
32                 reader.readAsDataURL(file);
33                 reader.onload = function() {
34                 imgResult = reader.result;
35                 };
36                 reader.onerror = function(error) {
37                 reject(error);
38                 };
39                 reader.onloadend = function() {
40                 resolve(imgResult);
41                 };
42             });
43         }
