北京营销网站建设公司,网站建设与维护前景,京东旗下的企业网站有哪些,同一个网站可以同时做竞价和优化html通过CDN引入Vue使用Vuex以及Computed、Watch监听 近期遇到个需求#xff0c;就是需要在.net MVC的项目中#xff0c;对已有的项目的首页进行优化#xff0c;也就是写原生html和js。但是咱是一个写前端的#xff0c;写html还可以#xff0c;.net的话#xff0c;开发也…html通过CDN引入Vue使用Vuex以及Computed、Watch监听 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。那么就意味着需要全局监听如果筛选条件改变那么所有的组件都需要监听到这个改变做出相应的反应。 效果图 代码实现
store.js
const store new Vuex.Store({state: {msg: Hello World,count: 5},mutations: {increment(state, payload) {console.log(的话,state,payload)state.count }},actions: {increment(context, payload) {setTimeout(() {context.commit(increment, payload);}, 2000);}},getters: {msg(state) {return state.msg.toUpperCase();},count(state) {return state.count;}},
});然后将store挂载到Vue上 主页面html !DOCTYPE html
