Vue触发input选取文件点击事件操作

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' @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
