接着第上一个，在js文件里再增加一个 popModal 模块，实现弹框效果
css 代码：

});
oModal.show();

js代码：
;(function(window,undefined){
//构造一个函数，参数为一个对象，实例化时，有值则进行传值，没有则赋值一个空对象
function popAlert( opt ){
this.opt = opt || {};
};
// 显示函数的设置
popAlert.prototype.show = function(){
// 创建一个div元素
var Odiv = document.createElement('div');
var that = this;
var aclose ;
// 给div添加class属性，这里使用的是多个属性的添加，同时将opt的class传递过来
Odiv.classList.add('alert',this.opt['class']||'' );
// 设定div包含的内容

// 影藏函数设置
popAlert.prototype.hide = function( obj ){
obj.style.display = 'none';

function popModal( opt ){
this.opt = opt || {};
};
popModal.prototype.show = function(){
var modalHtml = "<div class='modal fade'>";

};
// 设置一个空对象：huanying2015
var huanying2015 = {};
// 把popAlert和popModal 挂在huanying2015下面
huanying2015 = {
'popAlert' : popAlert,
'popModal' : popModal
};
// 然后把huanying2015挂在window 对象下面，这样就可以在外面使用huanying2015调用popAlert 了
window.huanying2015 = huanying2015;
})(window,undefined);
运行结果：
对于js部分，还可以再次进行封装：调用时直接填入模态框的内容进行调用
css部分：与上面的一样，不动
js部分：在原先的立即执行表达式函数后面封装一个函数 show_popModal();
;(function(window,undefined){
//构造一个函数，参数为一个对象，实例化时，有值则进行传值，没有则赋值一个空对象
function popAlert( opt ){
this.opt = opt || {};
};

}
};
return obj;
};
// 设置一个空对象：huanying2015
var huanying2015 = {};
// 把popAlert 挂在huanying2015下面
huanying2015 = {
'popAlert' : popAlert,
'popModal' : popModal
};
// 然后把huanying2015挂在window 对象下面，这样就可以在外面使用huanying2015调用popAlert 了
window.huanying2015 = huanying2015;
})(window,undefined);
// 这里再次进行封装 popModal
function show_popModal( content ){
var Opop = new huanying2015.popModal({
'title':"huanying2015 提示您",
'content':content
});
return Opop.show();
};
html部分： 注意，下面是直接调用show_popModal()
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" href="./css/layout1.css">
<script src="./js/layout.js"></script>
<script>
window.onload = function(){ show_popModal('这里是地球，火星人，欢迎您们来旅游！');
}
</script>
</head>
<body>
</body>
</html>
运行结果：
