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
以上这篇Vue触发input选取文件点击事件操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
