Vue触发input选取文件点击事件操作
作者:LaLaLa_heng
这篇文章主要介绍了Vue触发input选取文件点击事件操作,具有很好的参考价值,希望对大家有所帮助。一起跟随小编过来看看吧
CSS
.upload-btn-box { margin-bottom: 10px; button { margin-right: 10px; } input[type=file] { display: none; } }
HTML
<div class="upload-btn-box"> <Button @click="choiceImg" icon="ios-cloud-upload-outline" type="primary">点击上传</Button> <input ref="filElem" type="file" class="upload-file" @change="getFile"> </div>
Script
choiceImg(){ this.$refs.filElem.dispatchEvent(new MouseEvent('click')) }, getFile(){ var that = this; const inputFile = this.$refs.filElem.files[0]; if(inputFile){ if(inputFile.type !== 'image/jpeg' && inputFile.type !== 'image/png' && inputFile.type !== 'image/gif'){ alert('不是有效的图片文件!'); return; } this.imgInfo = Object.assign({}, this.imgInfo, { name: inputFile.name, size: inputFile.size, lastModifiedDate: inputFile.lastModifiedDate.toLocaleString() }) const reader = new FileReader(); reader.readAsDataURL(inputFile); reader.onload = function (e) { that.imgSrc = this.result; } } else { return; } }
补充知识: vue下打包时几个文件选择文件打包一起 并做懒加载
直接上代码
const DeviceManage = r => require.ensure([], () => r(require(deviceManagePath + 'main/DeviceManage')), 'g-DeviceManage'); const SingleDeviceSet = r => require.ensure([], () => r(require(deviceManagePath + 'deviceSet/SingleDeviceSet')), 'g-DeviceManage'); const ModifyNo = r => require.ensure([], () => r(require(deviceManagePath + 'modifyNo/ModifyNo')), 'g-DeviceManage'); const PricePerTime = r => require.ensure([], () => r(require(deviceManagePath + 'pricePerTime/PricePerTime')), 'g-DeviceManage'); const SetParams = r => require.ensure([], () => r(require(deviceManagePath + 'setParams/SetParams')), 'g-DeviceManage'); const ShowDevicePrice = r => require.ensure([], () => r(require(deviceManagePath + 'showDevicePrice/ShowDevicePrice')), 'g-DeviceManage'); const parameterSetting = r => require.ensure([], () => r(require(deviceManagePath + 'parameterSetting/parameterSetting')), 'g-DeviceManage'); const SetParams3G = r => require.ensure([], () => r(require(deviceManagePath + 'setParams3G/SetParams3G')), 'g-Device3Gparams');
这么写 所有g-DeviceManage的文件会被打包在一起
