一直搞不懂闭包问题，这次开发真的遇上了，求解决办法，要求各product分别展示出各自的属性

Question

$(document).ready(function() {    function product(name, description, price) {        this.name = name;        this.des = description;        this.price = price;    }var product1 = new product("iphone", "手机", 3200);    var product2 = new product("huawei", "手机", 1800);    var product3 = new product("nicai", "手机", 998);    var product4 = new product("sansung", "手机", 3000);    var product5 = new product("opera", "手机", 2000);    var products = [product1, product2, product3, product4, product5];    for(var j=0;j<products.length;j++) {        var pname = document.getElementsByClassName("pname")[j];        var pdes = document.getElementsByClassName("pdes")[j];        var pprice = document.getElementsByClassName("pprice")[j];        for(var i=0;i<products.length;i++) {            pname.innerHTML = products[i].name;            pdes.innerHTML = products[i].des;            pprice.innerHTML = products[i].price;        }    }    });
