我要评论在ecshop的目录/js/common.js中有一个openspediv方法是实现ecshop的弹窗效果的。如果我们想制作一个登录弹窗框，可以截取这个方法里的部分代码。
//生成属性选择层
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));
//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;
}
<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>
// 新激活图层
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";
//生成层内内容
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);
}
<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>
上面代码是与下拉选择框有关，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>
上面这与弹窗框里的内容有关，也去掉。
要制作一个登录弹窗框，我们再把需要传入的参数去掉，改一下方法名，var _id和var m的值，然后在newdiv.innerhtml 里面加上你想在弹窗框显示的html代码即可改写该方法。
新方法如下：
//弹窗登录
function openlogindiv()
{
var _id = "logindiv";
var m = "loginmask";
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;
}
// 新激活图层
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";
//生成层内内容
newdiv.innerhtml = '<form id="ajax_loginform">用户名：<br><input type="text" name="username" id="ajax_username"/>密码：<br><input type="password" name="username" id="ajax_password"/><br><button type="button">登录</button> <button type="button" onclick="closeloginform()">关闭</button></form>';
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);
}
然后在themes/default/library/page_header.lbi文件上把弹窗登录按钮显示到你想添加的位置，加上这一代码段：
<a href="javascript:openlogindiv();" rel="external nofollow" >弹窗登录</a>
再修改一下样式，让其更漂亮。样式修改在模板目录themes/default/style.css。加上这一段：
#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;}
最后再写个关闭弹窗的js事件即可。方法我写在common.js文件下的openlogindiv()之后
function closeloginform(){
document.body.removechild(docele('logindiv'));
document.body.removechild(docele('loginmask'));
}
效果如图：
以上所述是小编给大家介绍的使用openspediv方法实现ecshop登录弹窗框效果，希望对大家有所帮助
