去代码里找到这个变量的位置，看看这个变量的类型是不是不对，做个容错

if(data.cartProductVoList){ data.notEmpty = !!data.cartProductVoList.length; } 这是我改的判断，改完这个以后，购物车页面显示空空如也立即去购物，可是购物车中有两个商品这是list.do接口请求到的json数据 {"status":0,"data":{"cartProductVos":[{"id":127,"userId":1,"productId":26,"quantity":1,"productName":"ppp","productSubTitle":"ppp","productMainImage":"","productPrice":111.00,"productStatus":1,"productTotalPrice":111.00,"productStuck":111,"productCheck":1,"limitQuantity":"LIMIT_NUM_SUCCESS"},{"id":128,"userId":1,"productId":32,"quantity":1,"productName":"1111111","productSubTitle":"11111","productMainImage":"","productPrice":1111.00,"productStatus":1,"productTotalPrice":1111.00,"productStuck":1,"productCheck":1,"limitQuantity":"LIMIT_NUM_SUCCESS"}],"cartTotalPrice":1222.0,"imageHost":"http://img.lhmmall.cn/","check":true}}
