[Vue warn]: You are setting a non-existent path "answer" on a vm instance. Consider pre-initializing the property with the "data" option for more reliable reactivity and better performance.
說明:使用的變量“answer”沒有初始化,需要再data里聲明聲明。
[Vue warn]: Attributes "class", ":transition" are ignored on component <router-view> because the component is a fragment instance: http://vuejs.org/guide/components.html#Fragment-Instance
官方說,出現實例片段的原因如下:
- Template contains multiple top-level elements. (模版包涵了多個頂級元素 說白了 你的模版元素沒有唯一一個父元素)
- Template contains only plain text.(模版里面只包涵純文本)
- Template contains only another component (which can potentially be a fragment instance itself).(模版只包含另外一個組件,而這個組件本上可以就是一個fragment instance)
- Template contains only an element directive, e.g.
<partial>or vue-router’s<router-view>.(模版只包含<partial>或者<router-view>組件 ) - Template root node has a flow-control directive, e.g.
v-iforv-for.(模版根節點被v-if活着v-for有個邏輯判斷)
2、模板只包含普通文本。
3、模板只包含其它組件(其它組件可能是一個片段實例)。
4、模板只包含一個元素指令,如 或 vue-router 的 。
5、模板根節點有一個流程控制指令,如 v-if 或 v-for。
[Vue warn]: Error when evaluating expression "function (vm) {
return getter(vm.state);
}": Error: [vuex] Do not mutate vuex store state outside mutation handlers.
原因:在mutation外改變了state
export const avatar = (state) => {
state.user.avatar = appUser.avatar
return state.user.avatar
}
正確寫法:
export const avatar = (state) => {
return state.user.avatar
}
Uncaught TypeError: Cannot read property '__v_trans' of null
說明: 這個vm實例沒有指定el掛載點
[vue-router] Uncaught error during transition:
Uncaught TypeError: (0 , _dealHelper.getcStrategy) is not a function
原因:
router: {
data () {
//這里的代碼出錯
}
}
Uncaught Error: no content is found
我使用了vux的scroller,在scroller中做了個循環創建dom,如果沒有創建的話就會報這個錯誤,可見,在scroller至少應該包含一個容器.
