Question

这是我的路由文件，我正在尝试渲染shopping.hbs文件。我在console.log.Shopping-cart.hbs文件中获得了正确的输出，在我的商店文件夹里面查看。

ffmpeg -loop 1 -i pic001.jpg -i pic002.jpg -filter_complex "[0:v]scale=-1:720,zoompan=z='min(zoom+0.0015,1.5)':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':d=125,trim=duration=5[scaled_video];[1:v]scale=1920:1080,boxblur=15[blur_image];[blur_image][scaled_video]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2[outv]" -c:v libx264 -aspect 1280/720 -map [outv] -t 10 -y fixed.mp4

以下是generateArray的代码。如果我将数组传递到页面中，则页面呈现成功。

router.get('/shopping-cart',function(req,res,next){
    if(!req.session.cart)
    {
        return res.render('shop/shopping-cart',{products:null});    
    }
    var cart=new Cart(req.session.cart);
    console.log(cart.totalPrice);
    console.log(cart.generateArray());
    res.render('shop/shopping-cart',{products:cart.generateArray(),totalPrice: cart.totalPrice});
});

module.exports = router;

这是控制台的输出。

module.exports=function Cart(oldCart) {
    this.items=oldCart.items || {};
    this.totalQty=oldCart.totalQty || 0;
    this.totalPrice=oldCart.totalPrice || 0;

    this.add=function(item,id)
    {
        var storedItem=this.items[id];
        if(!storedItem)
        {
            storedItem=this.items[id]={item:item,qty:0,price:0};
        }
        storedItem.qty++;
        storedItem.price=storedItem.qty*storedItem.item.price;
        this.totalQty++;
        this.totalPrice+=storedItem.item.price;
    };

    this.generateArray=function(){
        var arr=[];
        for(var id in this.items){
            arr.push(this.items[id]);
        }
        return arr;
    };
};

这是我的shopping-cart.hbs文件，我正在迭代产品。

6000
[ { item: 
     { _id: '5a033713520a9414e9e6e0ac',
       imagePath: 'https://media.contentapi.ea.com/content/dam/ea/easports/fifa/features/2017/cristiano-ronaldo/june5/ronaldo-share.jpg',
       title: 'FIFA 2018',
       description: 'PC Game',
       price: 2000,
       __v: 0 },
    qty: 3,
    price: 6000 } ]

以下是句柄栏的配置设置

    {{ # if products }}
    <div class="row">
        <div class="col-sm-6 col-md-6 col-md-offset-3 col-sm-offset-3">
            <ul class="list-group">
                {{ # each products }}
                <li class="list-group-item">
                    <span class="badge">{{this.qty}}</span>
                    <strong>{{this.item.title}}</strong>
                    <span class="label label-success">Rs {{this.price}}</span>
                    <div class="btn-group">
                        <button class="btn btn-primary btn-xs dropdown-toggle" type="button" datatoggle="dropdown">Action<span class="caret"></span></button>
                        <ul class="dropdown-menu">
                            <li><a href="#">Reduce by 1</li>
                            <li><a href="#">Remove all</li>


                </ul>
                </div>
            </li>
            {{ /each }}
        </ul>
    </div>
</div>
<div class="row">
    <div class="col-sm-6 col-md-6 col-md-offset-3 col-sm-offset-3">
        <strong>Total : {{ totalPrice }}</strong>
    </div>
</div>
<div class="row">
    <div class="col-sm-6 col-md-6 col-md-offset-3 col-sm-offset-3">
        <button type="button" class="btn btn-success">Checkout</button>
    </div>
</div>
{{ else }}
<div class="row">
    <div class="col-sm-6 col-md-6 col-md-offset-3 col-sm-offset-3">
        <h2>No items in Cart</h2>
    </div>
</div>
{{ /if }}
