以下代码

Ext.define('ABC.view.ProductList',{
        extend : 'Ext.Panel',
        xtype : "productlist",
        itemId : 'Productlist',
        config : {
            layout : {
                type : 'fit'
            }
        },
        initialize : function() {
            var tpl = new Ext.XTemplate(
                '<tpl for="suggestions">',
                '<img src="{[this.image(values)]}">',
                '<h1>{name}</h1>',
                '<p>{description}</p>',
                '<span>{globalPrice}</span>',
                '</tpl>',{
                    image : function(value) {
                        var photoUrl = value.photoUrl;
                        var url = localStorage.httpPrefixAddress + photoUrl + '&token='+ localStorage.token;
                        return url;
                    }
                }
            );
            var productList = Ext.create("Ext.List", {
                itemId : 'Plist',
                emptyText : 'Empty',
                store : Ext.getStore('productStore'),
                itemTpl: tpl
            });
            this.add(productList);
        }
    });

我得到这样的输出，我的意思是它将每个东西显示为单个列表项。

@ThinkFloyd这就是我得到的，我试着按你说的那样

如你所见，有一条线用于设置高度

答案 0 :(得分：2)

好吧，正如我所看到的，你使用了一个我们通常与tpl配置一起使用的tpl，以便完整地模板渲染。对于list / dataview，我们不指定完整的tpl，而只指定项目的模板。因此我们使用itemTpl属性。对于您的情况，当您使用itemTpl（其中包含for循环）指定tpl时，它只执行一次并迭代所有建议并将其包含在第一个列表项中。

因此，对于您的情况，您应该使用商店的rootProperty将每个建议设置为模型实例，List将自动遍历商店以提供所需的功能。

商品 

Ext.define('ABC.store.productStore', {
  config : {
    ....
    rootProperty : 'suggestions'
  }
});

<强> itemTpl： 

var tpl = new Ext.XTemplate(
  '<img src="(photoUrl:this.image}">',
  '<h1>{name}</h1>',
  '<p>{description}</p>',
  '<span>{globalPrice}</span>', {
  image: function (photoUrl) {
    var url = localStorage.httpPrefixAddress + photoUrl + '&token=' + localStorage.token;
    return url;
  }
});

这应该适合你。

有时我观察到即使模板html很小但项目背景很大并且推动所有其他背景。你能尝试将你的tpl包装在一个div中并给出一些高度和边框，看模板是否正确渲染它？

var tpl = new Ext.XTemplate(
    '<div class="my-item">'
        '<tpl for="suggestions">',
        '<img src="{[this.image(values)]}">',
        '<h1>{name}</h1>',
        '<p>{description}</p>',
        '<span>{globalPrice}</span>',
        '</tpl>',
    '</div>',{
        image : function(value) {
            var photoUrl = value.photoUrl;
            var url = localStorage.httpPrefixAddress + photoUrl + '&token='+ localStorage.token;
            return url;
        }
    }
);

并在CSS中给出了一些高度＆amp;与.my-item的边界。删除图片功能后也请检查您的列表，或使用带背景图片的<div>代替<img>
