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) { <span style="color:#FF0000;"><span style="color:#FF0000;">openSpeDiv(result.message, result.goods_id, result.parent);</span></span> }将if中的内容换为
<span style="color:#FF0000;">openSpeDiv(result.message, result.goods_id, result.parent,result.goods_title,result.goods_thumb,result.goods_name);</span>
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 = '<div style="font-size:14;background:#fae3e9;width:480px;height:40px;line-height:40px;padding:0 10px;font-size:14px; "><span style="float:left; font-weight:bold">产品购买</span><a href=\'javascript:cancel_div()\' style="float:right;padding:0 26px 0 0;background:url(themes/xaphp/images/ico_closebig.gif) right center no-repeat;cursor:pointer;" >关闭</a></div><div class="cartpopDiv"><div class="toptitle"><a href="goods.php?id='+goods_id+'" class="pic"><img src='+goods_thumb+' /></a><p>'+goods_title+'</p></div>'; html += '<div class="coninfo">'; html +='<table cellspacing="7" cellpadding="0"><tr><td class="left"><span>品名：</span></td><td>'+goods_name+'</td></tr>'; for (var spec = 0; spec < message.length; spec++) { html +='<tr>'; html +='<td class="left" valign="top">'+message[spec]['name']+'：</td>'; html +='<td>'; html +='<ul class="choose">'; if (message[spec]['attr_type'] == 1) { for (var val_arr = 0; val_arr < message[spec]['values'].length; val_arr++) { if (val_arr == 0) { html += "<li id='aa_"+val_arr+"' ><a id="+val_arr+" class='selected' onclick='changeAtt(this,id,name)' name="+message[spec]['values'][val_arr]['id']+" href='javascript:;'><input style='display:none' type='radio' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' /><span>" + message[spec]['values'][val_arr]['label'] +'</span><i></i></a></li>'; } else { html += "<li id='aa_"+val_arr+"' ><a onclick='changeAtt(this,id,name)' id="+val_arr+" name="+message[spec]['values'][val_arr]['id']+" href='javascript:;'><input style='display:none' type='radio' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' /><span>" + message[spec]['values'][val_arr]['label'] + '</span><i></i></a></li>'; } } html += "<input type='hidden' name='spec_list1' id='spe_num' value='" + val_arr + "' />"; html += "<input type='hidden' name='spec_list' value='" + val_arr + "' />"; } else { for (var val_arr = 0; val_arr < message[spec]['values'].length; val_arr++) { html += "<li><input type='checkbox' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' />" + message[spec]['values'][val_arr]['label'] + '</li>'; } html += "<input type='hidden' name='spec_list' value='" + val_arr + "' />"; } html +='</ul>'; html +='</td>' html +='</tr>'; } html += '</table>'; html +='</div>'; html +="<div class='botmbtn'><a href='javascript:submit_div(" + goods_id + "," + parent + ")'><img type='image' src='themes/xaphp/images/btn_addcart.png'></a> <a href='javascript:collect("+goods_id+")'><img type='image' src='themes/xaphp/images/btn_favorite.png'></a></div>"; html +='</div></div>'; newDiv.innerHTML = html; document.body.appendChild(newDiv); // mask图层 var newMask = document.createElement("div"); newMask.id = m; newMask.style.position = "absolute"; newMask.style.zIndex = "9999"; newMask.style.width = document.body.scrollWidth + "px"; newMask.style.height = document.body.scrollHeight + "px"; newMask.style.top = "0px"; newMask.style.left = "0px"; newMask.style.background = "#FFF"; newMask.style.filter = "alpha(opacity=30)"; newMask.style.opacity = "0.40"; document.body.appendChild(newMask);}2.在flow.php中的
if ($_REQUEST['step'] == 'add_to_cart')
里
$result['error'] = ERR_NEED_SELECT_ATTR; $result['goods_id'] = $goods->goods_id; $result['parent'] = $goods->parent; $result['message'] = $spe_array;下面添加
$goods_row = $GLOBALS['db']->getRow("select goods_name,goods_title,goods_thumb from ".$GLOBALS['ecs']->table('goods')." where goods_id='".$goods->goods_id."'");$result['goods_title']= $goods_row['goods_title'];$result['goods_thumb']= $goods_row['goods_thumb'];$result['goods_name'] = $goods_row['goods_name'];大功告成
