问题:最近发现一个奇怪的bug, 那就是在上传图片需要采用input type=file来进行文件选择.由于为了适应美工的UI图,所以是把选择文件的input框隐藏了.然后通过另外一个按钮的点击事件来触发input的选择事件.代码如下: <div style="width:120px;height:120px"> <img src="/image/uploadfile.png" style="width:100%;height:100%&…

在项目过程中遇到的需要上传本地文件,file的原始控件不太美观,但是这个控件和button有点不太一样, 改变这个样式的思路就是在控件外面套一层链接,然后把file控件的透明度设置为0(透明).样式只需要对外面那层进行操作就行. html代码: <td style="text-align: left;"> <a href="javascript:;" class="file">选择文件 <input type=&qu…

问题描述 在最近的项目开发中遇到了这样的一个问题,当我上传了一个文件时,我将获取到的文件名清空后,却无法再次上传相同的文件 <template> <div class="hello"> <input type="button" value="上传文件" name="" id="" @click="updata"> <input type=&quo…

解决掉了最头疼的DirectoryWatcher内部实现,这一节可以结束NodeWatchFileSystem模块. 关于watch的应用场景,仔细思考了下,这不就是热重载的核心嘛. 首先是监视文件,触发文件change事件后收集变动文件信息,重新进行打包,更新JS后触发页面重新渲染,perfect! 首先重新回忆一下NodeWatchFileSystem模块: "use strict"; const Watchpack = require("watchpack")…

前言 在以往的java开发中,程序员最怕大量的配置,是因为配置一多就不好统一管理,经常出现找不到配置的情况.而项目中,从开发测试环境到生产环境,往往需要切换不同的配置,如测试数据库连接换成生产数据库连接,若有一处配错或遗漏,就会带来不可挽回的损失.正因为这样,spring boot给出了非常理想的解决方案——application.properties.见application-properties的官方文档:http://docs.spring.io/spring-boot/docs/curr…
