效果图：
html 代码：
<el-form-item label="Excel文件" :label-width="formLabelWidth" prop="excelurl">
<el-upload class="avatar-uploader"
ref="upload"
action="//up.qbox.me/"
:auto-upload="false"
:show-file-list="false"
:on-success="handleFileSuccess"
:on-error="handleFileError"
:on-change="handleChange"
:before-upload="beforeFileUpload"
:data="uploadFile">
<el-button slot="trigger" size="small" type="primary" class="file-select-btn">选择文件</el-button>
<el-button class="upload-file-btn" size="small" type="primary" :disabled="isSuccessUpload" @click="uploadAction">上传</el-button>
</el-upload>
<el-input type="text" v-model="form.excelurl" class="upload-file-input" v-if="fileState" disabled></el-input>
<el-button size="small" type="primary" class="change-file-btn" v-if="btnState" @click="fileState=false;btnState=false">修改</el-button>
</el-form-item>
其中: auto-upload="false" 为选择文件后不立即上传 on-change="handleChange" 为状态改变立即触发
Js代码：
beforeFileUpload(file) {
let filetype = file.name.slice(file.name.lastIndexOf('.'),file.name.length)
if (filetype === '.xls' || filetype === '.xlsx') {
// return true
} else {
this.$message.error('请上传EXCEL格式文件')
return false
}
const isLt2M = file.size / 1024 / 1024 < 2
if (!isLt2M) {
this.$message.error('上传文件大小不能超过 2MB!')
return false;
}
},
handleChange(file){
if(!this.fileState){
this.$http.post(GET_UPLOAD_TOKEN, {}).then(res => {
if (res.data.ret === 0) {
this.uploadFile = {key:file.name,token : res.data.data.upToken}
this.form.excelurl = file.name
this.fileState = true
}else{
return false
}
})
}
},
uploadAction(){
this.$refs.upload.submit()
},
上传成功：
注：
在上传七牛时通过给key赋值，上传了原本的文件名，不通过七牛随机产生
通过on-change函数在选择文件后，请求到token, 然后再上传文件
