推荐地址：https://www.cnblogs.com/yuanxiaojian/p/6293784.html，以下内容为拿出来的部分，方便大家使用。
1.创建一个css文件，我的为alert.css,把下面内容拿过去
.win { display: none; }
.mask-layer { position: fixed; width: 100%; height: 100%; opacity: 0.5; filter: alpha(opacity=50); background-color: black; z-index: 99998; top: 0px; left: 0px; }
.window-panel { position: fixed; z-index: 99999; top: 50%; left: 50%; background-color: white; border-radius: 4px;}
.window-panel .title-panel { position: absolute; height: 36px; width: 100%; border-radius: 4px 4px 0 0; }
.window-panel .title { position: absolute; height: 36px; width: 100%; text-align: center; border-radius: 4px 4px 0 0; line-height: 36px; vertical-align: middle; background-color: whitesmoke; /*标题背景色*/ border-bottom: 1px solid rgb(233, 233, 233); z-index: 1; }
.window-panel h3 { font-size: 16px; margin: 0; }
.window-panel .close-btn { display: block; text-align: center; vertical-align: middle; position: absolute; width: 36px; height: 36px; line-height: 36px; right: 0px; text-decoration: none; font-size: 24px; color: black; background-color: #DBDBDB; border-radius: 2px; z-index: 1; }
.window-panel .close-btn:hover { background-color: #ccc; }
.window-panel .body-panel { position: absolute; width: 100%; top: 36px; border-radius: 0 0 4px 4px; z-index: 1;background: #fff;background-image: url(../images/wenli.png); }
.window-panel .body-panel.toast-panel{ position: absolute;color:#fff;background:rgba(0,0,0,0.3); }
.window-panel .content, .window-panel .btns { text-align: center; }
.window-panel .content { padding: 10px 10px 0px 10px; font-size: 16px; min-height: 40px; line-height: 22px; }
.window-panel .content.toast-content{padding:0;min-height:0;}
.window-panel .w-btn { display: inline-block; width: 60px; height: 26px; line-height: 26px; background-color: #DE5923; color: white; cursor: pointer; text-align: center; border-radius: 2px; text-decoration: none; margin: 0 10px 0px 10px; border: none; }
.window-panel .w-btn:hover { background-color: #DA3E00; }
.window-panel .w-btn:focus { outline: 0 none; }

2.创建一个ui.js文件，名字随意，以下内容拿走
var mizhu = new function() {
// console.log("window的宽+"+$(window).width()+)
this.width = $(window).width() * 0.5;
this.height = 172;
console.log("window的宽+"+$(window).width()+this.width)
this.close = function() {
$('.win iframe').fadeOut();
$('.win').fadeOut("fast");
setTimeout(function() {
$('.win iframe').remove();
$('.win').remove();
}, 200);
};

this.open = function(width, height, title, url, closed) {
this._close = function() {
this.close();
if($.isFunction(closed)) closed();
};
var html = '<div class="win"><div class="mask-layer"></div><div class="window-panel"><iframe class="title-panel" frameborder="0" marginheight="0" marginwidth="0" scrolling="no"></iframe><div class="title"><h3></h3></div><a href="javascript:void(0)" onclick="mizhu._close();" class="close-btn" title="关闭">×</a><iframe class="body-panel" frameborder="0" marginheight="0" marginwidth="0" scrolling="auto" src=""></iframe></div></div>';
var jq = $(html);
jq.find(".window-panel").height(mizhu.height).width(mizhu.width).css("margin-left", -mizhu.width / 2).css("margin-top", -mizhu.height);
jq.find(".title").find(":header").html(title);
jq.find(".body-panel").height(height - 36).attr("src", url);
jq.appendTo('body').fadeIn("fast");
$(".win .window-panel").focus();
};

this.confirm = function(title, message, selected) {
this._close = function(flag) {
if(flag) {
$(".win").remove();
selected(flag);
} else {
this.close();
};
};

var html = '<div class="win"><div class="mask-layer"></div><div class="window-panel"><iframe class="title-panel" frameborder="0" marginheight="0" marginwidth="0" scrolling="no"></iframe><div class="title"><h3></h3></div><div class="body-panel"><p class="content"></p><p class="btns"><button class="w-btn" tabindex="1" onclick="mizhu._close(false);">取消</button><button class="w-btn" onclick="mizhu._close(true);">确定</button></p></div></div></div>';
messageBox(html, title, message);
};

this.alert = function(title, message, ico) {
var icon = "";
if(!valempty(ico)) {
icon = '<p class="btns" style="margin-bottom:-15px;"><img width="70px" height="70px" src="images/' + ico + '.png"></p>';
}
var html = '<div class="win"><div class="mask-layer"></div><div class="window-panel"><iframe class="title-panel" frameborder="0" marginheight="0" marginwidth="0" scrolling="no"></iframe><div class="title"><h3></h3></div><div class="body-panel">' + icon + '<p class="content"></p><p class="btns"><button class="w-btn" tabindex="1" onclick="mizhu.close();">确定</button></p></div></div></div>';
messageBox(html, title, message);
}

this.toast = function(message, time) {
var html = '<div class="win"><div class="window-panel"><iframe class="title-panel" frameborder="0" marginheight="0" marginwidth="0" scrolling="no"></iframe><div class="body-panel toast-panel"><p class="content toast-content"></p></div></div></div>';
messageBox(html, "", message, "toast");
setTimeout(function() {
mizhu.close();
}, time || 3000);
}
};

function valempty(str) {
if(str == "null" || str == null || str == "" || str == "undefined" || str == undefined || str == 0) {
return true;
} else {
return false;
}
}

3.引入这两个文件，就ok了
使用方法：mizhu.alert('alert_带标题', '这是alert效果');

3.引入这两个文件，使用方法：Showbo.Msg.alert('您好，请先注册或登录!')
