在ECSHOP的目錄/JS/common.js中有一個openSpeDiv方法是實現ECSHOP的彈窗效果的。如果我們想制作一個登錄彈窗框，可以截取這個方法里的部分代碼。
//生成屬性選擇層 function openSpeDiv(message, goods_id, parent) { var _id = "speDiv"; var m = "mask"; if (docEle(_id)) document.removeChild(docEle(_id)); if (docEle(m)) document.removeChild(docEle(m)); //計算上卷元素值 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; } <span style="color:#ff0000;"> var i = 0; var sel_obj = document.getElementsByTagName('select'); while (sel_obj[i]) { sel_obj[i].style.visibility = "hidden"; i++; }</span> // 新激活圖層 var newDiv = document.createElement("div"); newDiv.id = _id; newDiv.style.position = "absolute"; newDiv.style.zIndex = "10000"; newDiv.style.width = "300px"; newDiv.style.height = "260px"; newDiv.style.top = (parseInt(scrollPos + 200)) + "px"; newDiv.style.left = (parseInt(document.body.offsetWidth) - 200) / 2 + "px"; // 屏幕居中 newDiv.style.overflow = "auto"; newDiv.style.background = "#FFF"; newDiv.style.border = "3px solid #59B0FF"; newDiv.style.padding = "5px"; //生成層內內容 newDiv.innerHTML = '<h4 style="font-size:14; margin:15 0 0 15;">' + select_spe + "</h4>"; <span style="color:#ff0000;">for (var spec = 0; spec < message.length; spec++) { newDiv.innerHTML += '<hr style="color: #EBEBED; height:1px;"><h6 style="text-align:left; background:#ffffff; margin-left:15px;">' + message[spec]['name'] + '</h6>'; if (message[spec]['attr_type'] == 1) { for (var val_arr = 0; val_arr < message[spec]['values'].length; val_arr++) { if (val_arr == 0) { newDiv.innerHTML += "<input style='margin-left:15px;' type='radio' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' checked /><font color=#555555>" + message[spec]['values'][val_arr]['label'] + '</font> [' + message[spec]['values'][val_arr]['format_price'] + ']</font><br />'; } else { newDiv.innerHTML += "<input style='margin-left:15px;' type='radio' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' /><font color=#555555>" + message[spec]['values'][val_arr]['label'] + '</font> [' + message[spec]['values'][val_arr]['format_price'] + ']</font><br />'; } } newDiv.innerHTML += "<input type='hidden' name='spec_list' value='" + val_arr + "' />"; } else { for (var val_arr = 0; val_arr < message[spec]['values'].length; val_arr++) { newDiv.innerHTML += "<input style='margin-left:15px;' type='checkbox' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' /><font color=#555555>" + message[spec]['values'][val_arr]['label'] + ' [' + message[spec]['values'][val_arr]['format_price'] + ']</font><br />'; } newDiv.innerHTML += "<input type='hidden' name='spec_list' value='" + val_arr + "' />"; } } newDiv.innerHTML += "<br /><center>[<a href='javascript:submit_div(" + goods_id + "," + parent + ")' class='f6' >" + btn_buy + "</a>] [<a href='javascript:cancel_div()' class='f6' >" + is_cancel + "</a>]</center>";</span> document.body.appendChild(newDiv); // mask圖層 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); } <span style="color: rgb(255, 0, 0);"> var i = 0; var sel_obj = document.getElementsByTagName('select'); while (sel_obj[i]) { sel_obj[i].style.visibility = "hidden"; i++; }</span> 上面代碼是與下拉選擇框有關，去掉。
<span style="color: rgb(255, 0, 0);">for (var spec = 0; spec < message.length; spec++) { newDiv.innerHTML += '<hr style="color: #EBEBED; height:1px;"><h6 style="text-align:left; background:#ffffff; margin-left:15px;">' + message[spec]['name'] + '</h6>'; if (message[spec]['attr_type'] == 1) { for (var val_arr = 0; val_arr < message[spec]['values'].length; val_arr++) { if (val_arr == 0) { newDiv.innerHTML += "<input style='margin-left:15px;' type='radio' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' checked /><font color=#555555>" + message[spec]['values'][val_arr]['label'] + '</font> [' + message[spec]['values'][val_arr]['format_price'] + ']</font><br />'; } else { newDiv.innerHTML += "<input style='margin-left:15px;' type='radio' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' /><font color=#555555>" + message[spec]['values'][val_arr]['label'] + '</font> [' + message[spec]['values'][val_arr]['format_price'] + ']</font><br />'; } } newDiv.innerHTML += "<input type='hidden' name='spec_list' value='" + val_arr + "' />"; } else { for (var val_arr = 0; val_arr < message[spec]['values'].length; val_arr++) { newDiv.innerHTML += "<input style='margin-left:15px;' type='checkbox' name='spec_" + message[spec]['attr_id'] + "' value='" + message[spec]['values'][val_arr]['id'] + "' id='spec_value_" + message[spec]['values'][val_arr]['id'] + "' /><font color=#555555>" + message[spec]['values'][val_arr]['label'] + ' [' + message[spec]['values'][val_arr]['format_price'] + ']</font><br />'; } newDiv.innerHTML += "<input type='hidden' name='spec_list' value='" + val_arr + "' />"; } } newDiv.innerHTML += "<br /><center>[<a href='javascript:submit_div(" + goods_id + "," + parent + ")' class='f6' >" + btn_buy + "</a>] [<a href='javascript:cancel_div()' class='f6' >" + is_cancel + "</a>]</center>";</span> 上面這與彈窗框里的內容有關，也去掉。
要制作一個登錄彈窗框，我們再把需要傳入的參數去掉，改一下方法名，var _id和var m的值，然后在newDiv.innerHTML 里面加上你想在彈窗框顯示的HTML代碼即可改寫該方法。
新方法如下：
//彈窗登錄 function openLoginDiv() { var _id = "loginDiv"; var m = "loginMask"; if (docEle(_id)) document.removeChild(docEle(_id)); if (docEle(m)) document.removeChild(docEle(m)); //計算上卷元素值 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; } // 新激活圖層 var newDiv = document.createElement("div"); newDiv.id = _id; newDiv.style.position = "absolute"; newDiv.style.zIndex = "10000"; newDiv.style.width = "300px"; newDiv.style.height = "260px"; newDiv.style.top = (parseInt(scrollPos + 200)) + "px"; newDiv.style.left = (parseInt(document.body.offsetWidth) - 200) / 2 + "px"; // 屏幕居中 newDiv.style.overflow = "auto"; newDiv.style.background = "#FFF"; newDiv.style.border = "3px solid #59B0FF"; newDiv.style.padding = "5px"; //生成層內內容 newDiv.innerHTML = '<form id="ajax_loginForm">用戶名：<br><input type="text" name="username" id="ajax_username"/>密碼：<br><input type="password" name="username" id="ajax_password"/><br><button type="button">登錄</button> <button type="button" onclick="closeLoginForm()">關閉</button></form>'; document.body.appendChild(newDiv); // mask圖層 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); } 然后在themes/default/library/page_header.lbi文件上把彈窗登錄按鈕顯示到你想添加的位置，加上這一代碼段：
<a href="JavaScript:openLoginDiv();" rel="external nofollow" >彈窗登錄</a>
再修改一下樣式，讓其更漂亮。樣式修改在模板目錄themes/default/style.css。加上這一段：
#ajax_loginForm{padding:10px; line-height:2em;} #ajax_loginForm input{width:98%; height:35px; padding:0 1%; line-height:35px; border:1px solid #e7e7e7; border-radius:3px;} #ajax_loginForm button{background:#ff6599; border: none; color:#fff; font-size:16px; border-radius:3px; padding:5px 15px; cursor:pointer;} 最后再寫個關閉彈窗的js事件即可。方法我寫在common.js文件下的openLoginDiv()之后
function closeLoginForm(){ document.body.removeChild(docEle('loginDiv')); document.body.removeChild(docEle('loginMask')); }效果如圖：
