html通过CDN引入Vue实现页面模块可拖拽
近期遇到个需求，就是需要在.net MVC的项目中，对已有的项目的首页进行优化，也就是写原生html和js。但是咱是一个写前端的，写html还可以，.net的话，开发也不方便，还得安装Visual Studio启动项目。所以就计划在html文件中开发，然后移植到.net的项目中。
功能说明：需要开发一个dashboard，也就是大屏可视化，多个模块，然后由图表作为主要内容。然后就衍生了一个需求，使用户能够自行拖放这个模块，改变模块的位置。这里用到了vue-grid-layout和vue-gird-item。这是vue自带的。效果较好。
效果图：
代码实现
代码说明：这个功能是由gird实现的，可见数组中有一些重要的参数
x:即横坐标，在第几列，和col-num有一定关联。可呈倍数使用
y:即纵坐标，在第几行
w:即宽度，也和col-num有一定关联
h:即高度
i:可立即为id，模块的唯一标识
layoutUpdatedEvent:这个方法会打印出移动后的数组信息，可用于后台持久化。保存数据，然后用于页面刷新初始值。
