通过本教程可以实现ECSHOP购买商品选择属性时弹出层来选择，效果如下图：1.在commen.js中找到function addToCartResponse(result)中的 else if (result.error == 6) { openSpeDiv(result.message, result.goods_id, result.parent); }将if中的内容换为openSpeDiv(result.message, result.goods_id, result.parent,result.goods_title,result.goods_thumb,result.goods_name);将function openSpeDiv(message, goods_id, parent)整个函数，替换为function openSpeDiv(message, goods_id, parent,goods_title,goods_thumb,goods_name) { var _id = "speDiv"; var m = "mask"; if (docEle(_id)) document.removeChild(docEle(_id)); if (docEle(m)) document.removeChild(docEle(m)); //计算上卷元素值 var scrollPos; if (typeof window.pageYOffset != 'undefined') { scrollPos = window.pageYOffset; } else if (typeof document.compatMode != 'undefined' && document.compatMode != 'BackCompat') { scrollPos = document.documentElement.scrollTop; } else if (typeof document.body != 'undefined') { scrollPos = document.body.scrollTop; } var i = 0; var sel_obj = document.getElementsByTagName('select'); while (sel_obj[i]) { sel_obj[i].style.visibility = "hidden"; i++; } // 新激活图层 var newDiv = document.createElement("div"); newDiv.id = _id; newDiv.style.position = "absolute"; newDiv.style.zIndex = "10000"; newDiv.style.width = "500px"; newDiv.style.height = "380px"; newDiv.style.top = (parseInt(scrollPos + 200)) + "px"; newDiv.style.left = (parseInt(document.body.offsetWidth) - 400) / 2 + "px"; // 屏幕居中 newDiv.style.background = "#fff"; newDiv.style.border = "5px solid #ffcae3"; var html = ''; //生成层内内容 html = '产品购买关闭
