commit
dispatch
在store js文件中定义
state: {
shopId: ""
},
mutations: {
// shopid
SETID (state, data) {
console.log("app-mutation", data)
state.oldshopId = state.shopId
state.shopId = data // 获取传来的值
}
},
.//设置
let str = JSON.stringify(this.newShop);
localStorage.setItem('shop',str) ---将值保存在缓存中
this.$store.dispatch('getParamSync',JSON.parse(localStorage.getItem('shop')))
this.$store.commit(' SETID',JSON.parse(localStorage.getItem('shop')).shopId)
//获取 --- 注意得在HTML中显示变量
computed: {
...mapState({
themeColor: state => state.app.themeColor,
menuColor: state =>
{
console.log('nav', state)
return state.app.menuColor
},
collapse: state =>{
return state.app.collapse
},
shopId: state => { //shopId 自定义
return state.app.shopId
},
}),
},

this.$store.commit('toShowLoginDialog', true);
this.$store.dispatch('toShowLoginDialog',false)主要区别是:
dispatch:含有异步操作,例如向后台提交数据,写法: this.$store.dispatch('mutations方法名',值)
commit:同步操作,写法:this.$store.commit('mutations方法名',值)
