在vue项目中使用element-ui的Upload上传组件
<el-upload v-else class='ensure ensureButt' :action="importFileUrl" :data="upLoadData" name="importfile" :onError="uploadError" :onSuccess="uploadSuccess" :beforeUpload="beforeAvatarUpload" > <el-button size="small" type="primary">确定</el-button>
其中importFileUrl是后台接口,upLoadData是上传文件时要上传的额外参数,uploadError是上传文件失败时的回掉函数,uploadSuccess是文件上传成功时的回掉函数,beforeAvatarUpload是在上传文件之前调用的函数,我们可以在这里进行文件类型的判断。
data () { importFileUrl: 'http:dtc.com/cpy/add', upLoadData: { cpyId: '123456', occurTime: '2017-08' } }, methods: { // 上传成功后的回调 uploadSuccess (response, file, fileList) { console.log('上传文件', response) }, // 上传错误 uploadError (response, file, fileList) { console.log('上传失败,请重试!') }, // 上传前对文件的大小的判断 beforeAvatarUpload (file) { const extension = file.name.split('.')[1] === 'xls' const extension2 = file.name.split('.')[1] === 'xlsx' const extension3 = file.name.split('.')[1] === 'doc' const extension4 = file.name.split('.')[1] === 'docx' const isLt2M = file.size / 1024 / 1024 < 10 if (!extension && !extension2 && !extension3 && !extension4) { console.log('上传模板只能是 xls、xlsx、doc、docx 格式!') } if (!isLt2M) { console.log('上传模板大小不能超过 10MB!') } return extension || extension2 || extension3 || extension4 && isLt2M } }
