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。一起跟随长沙网络推广过来看看吧
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
