二、模拟后台，传数据

1、static文件夹下创建mock文件夹，在mock下创建index.json文件

index.json文件模版

2、修改index.js配置文件

proxyTable: {
          '/api':{
            target:'http://localhost:8484',
            pathRewrite:{
              '^/api':'/static/mock'
            }
          }
        },

三、vuex

1、命令行cnpm install vuex --save安装vuex，并新建vuex文件index.js,内容以下

2、在state下定义需要的变量，在mutations下修改

3、在main.js中引用、和new Vue中定义

4、在任何组件中都可这样使用

5、在组件中通过commit提交数据给store中的conmutation修改，changeCity名称和store中定义的名称要相同
