state也就是vuex里的值，联想互动软件开发（T：I8O-285I-O282) 也即是整个vuex的状态，而strict和state的设置有关，如果设置strict为true，那么不能直接修改state里的值，只能通过mutation来设置
例1:
复制代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.16/dist/vue.js"></script>
<script src="https://unpkg.com/vuex@3.1.0/dist/vuex.js"></script>
</head>
<body>
<div id="app">
<p>count:{{count}}</p>
</div>
<script>
const store = new Vuex.Store({
state:{count:1}
})
var app = new Vue({
el:"#app",
store,
computed:{
count(){return store.state.count }
}
})
</script>
</body>
</html>
复制代码
渲染如下:
当我们在控制台修改store.state.coun里的值时页面会自动更新，例如:
此时页面自动更新了，变为了:
我们设置一个strict属性看看:例2:

<script>
const store = new Vuex.Store({
state:{count:1},
strict:true //新增一个strict属性，值为true
})
var app = new Vue({
el:"#app",
store,
computed:{
count(){return store.state.count }
}
})
