用ui.router 支持路由嵌套
不要用自帶的ng-route，這個(gè)不支持路由嵌套

建議你把completed 維護(hù)為一個(gè)狀態(tài)，計(jì)算屬性里根據(jù)這一個(gè)狀態(tài)進(jìn)行過濾就好了。
如：status = [all: 全部, open: 未完成, closed: 已完成];

   filterlists:function(){
       if(this.status === 'all') {
           return this.lists;
       } else {
           return this.lists.filter(value => this.status === 'closed' ? value.ischeck : !value.ischeck)
       }
   }

先給建議，看看能否有幫助：
1、查看下server項(xiàng)目中對(duì)應(yīng)的頁面被加載前是否引入了 portal 中controller文件（controller/header）；
2、server 和 portal 聲明header的controller的模塊名稱是否為同一個(gè)：例如angular.module(“模塊名稱”).controller("header")

可以用elementUI提供的$confirm方法，這樣簡單很多。內(nèi)容也可以是html

this.$confirm('地址確認(rèn)')
    .then( _ => {
        this.$confirm('聯(lián)系人確認(rèn)')
            .then( _ => {
                // ...
            } )
    } )

假設(shè)有n個(gè)項(xiàng)目
每個(gè)項(xiàng)目的人數(shù)分別為: k1,k2,k3....kn，總?cè)藬?shù)為k1+k2+k3+....+kn=sum

則這些項(xiàng)目組的人員的投票權(quán)重為: k1/sum,k2/sum,k3/sum....kn/sum

自己解決了 用$set方法就可以了

userath()這個(gè)函數(shù)是沒有返回值的
響應(yīng)的話 ctx.body=response

mongoose支持promise，配合await使用

try{
    var user = awiat userModel.find({name: ctx.request.body.username});
    if(user.length == 0){
        ctx.body = "user not register"
    } else {
        let user = await userModel.find({
            name: ctx.request.body.username,
            password: ctx.request.body.password
            });
        if (user == null || user.length == 0) {
            console.log(user);
            console.log('password wrong');
            ctx.body = "login fail";
         
        }
        if (user != null && user.length > 0) {
            console.log('login sccessful');
            ctx.body = "login successful";
        }
    }
} catch(e){
}

只要找到View（ViewHolder）顯示隱藏的調(diào)用函數(shù)，就能計(jì)算出每個(gè)View（ViewHolder）的顯示時(shí)長。

很幸運(yùn)的時(shí)，RecyclerView提供了這樣的接口函數(shù)，而且還是兩對(duì)接口函數(shù)：

1.RecyclerView#Adapter提供了一對(duì)函數(shù)：onViewAttachedToWindow(VH)和onViewDetachedFromWindow(VH)

public abstract static class Adapter<VH extends ViewHolder> {
    ... ...
    
    /**
     * Called when a view created by this adapter has been attached to a window.
     *
     * <p>This can be used as a reasonable signal that the view is about to be seen
     * by the user. If the adapter previously freed any resources in
     * {@link #onViewDetachedFromWindow(RecyclerView.ViewHolder) onViewDetachedFromWindow}
     * those resources should be restored here.</p>
     *
     * @param holder Holder of the view being attached
     */
    public void onViewAttachedToWindow(VH holder) {
    }

    /**
     * Called when a view created by this adapter has been detached from its window.
     *
     * <p>Becoming detached from the window is not necessarily a permanent condition;
     * the consumer of an Adapter's views may choose to cache views offscreen while they
     * are not visible, attaching and detaching them as appropriate.</p>
     *
     * @param holder Holder of the view being detached
     */
    public void onViewDetachedFromWindow(VH holder) {
    }

    ... ...
}

2.RecyclerView提供了OnChildAttachStateChangeListener接口：

public interface OnChildAttachStateChangeListener {

    /**
     * Called when a view is attached to the RecyclerView.
     *
     * @param view The View which is attached to the RecyclerView
     */
    void onChildViewAttachedToWindow(View view);

    /**
     * Called when a view is detached from RecyclerView.
     *
     * @param view The View which is being detached from the RecyclerView
     */
    void onChildViewDetachedFromWindow(View view);
}

上面的兩對(duì)接口函數(shù)，根據(jù)情況選用其一就好了，基本實(shí)現(xiàn)邏輯：

1. 設(shè)置兩個(gè)變量，一個(gè)用來保存AttachedToWindow被調(diào)用時(shí)的時(shí)間戳，一個(gè)用來保存顯示的總時(shí)長
2. DetachedFromWindow被調(diào)用時(shí)，計(jì)算與AttachedToWindow的時(shí)間戳差值，并將AttachedToWindow的時(shí)間戳清零，然后總時(shí)長加上這個(gè)差值
3. AttachedToWindow后，DetachedFromWindow未被調(diào)用前，只需獲取當(dāng)前系統(tǒng)時(shí)間戳，然后計(jì)算與AttachedToWindow的時(shí)間戳差值，再加上總時(shí)長，就是總時(shí)長

看看這個(gè)

background-position:10px 20px

背景定位，接收兩個(gè)值x偏移和y偏移，值可以是top/right/bottom/left或者px或者相對(duì)于父元素的%
點(diǎn)擊查看w3c參考

本身就不支持。你用到什么技術(shù)就要在vscode擴(kuò)展選項(xiàng)里面下載相應(yīng)的插件。才能支持對(duì)應(yīng)語言的語法高亮

1. 給三個(gè)inline-block加上vertical-align:top;

2. 用float: left來布局

該方法的參數(shù)可以是一個(gè)字符串路徑。

所以傳字符串的時(shí)候需要是個(gè)路徑，而不是name。
另外，你的多路由出口是什么概念，就是兩個(gè)獨(dú)立的項(xiàng)目，還是根據(jù)用戶權(quán)限分配不同的跳轉(zhuǎn)規(guī)則？

// 目錄變成
src
|
|---- aProject
|---- aProject

修改config/index.js

const projectName = process.argv[2]
index: path.resolve(__dirname, `../dist/{$projectName}/index.html`),
assetsRoot: path.resolve(__dirname, `../dist/{$projectName}/`),

修改build/webpack.base.conf.js

const projectName = process.argv[2]
app: `./src/${$projectName}/main.js`

然后啟動(dòng)項(xiàng)目的時(shí)候就
npm run dev -- aProject
npm run dev -- bProject
啟動(dòng)各自的項(xiàng)目

可以先獲取到頁面上那個(gè)盒子的jquery對(duì)象，然后克隆一下,再進(jìn)行append
var $box = $('#box').clone();
$('.container').append($box);

其次注意一下你這里的$(this)是什么，確定是否是你打算append進(jìn)的那個(gè)容器

Vue.set

可以嘗試重新下載node_modules

cl-md比cl-sm要長啊

時(shí)間盡量使用時(shí)間戳。
比較可以直接使用時(shí)間戳相減了。也可以使用momentjs的一些方法，比如：isAfter isBefore等。

應(yīng)該是table里的單元格寬度寫死了
