仿选择版本页

描述：
有不同组类型，即类型A和类型B，类型包含具体型号类型如A_a、A_b等等。
具体型号类型有三种状态：可选状态、选中状态、不可选状态，可选状态具有态胎效果。
选中状态时按钮下一步变为可点击状态。

基础知识：
css方面内外边距的使用、二态效果、样式表中的类的使用等
js方面设计点击事件、闭包等。

效果如下图：

js源码及简单介绍：

/*
*  getId函数
*  功能：获取元素ID
*/
function getId(){
    return document.getElementById(arguments[0]);
}

/*
*  getTagNames函数
*  参数kname：元素标签名称
*  参数pid：元素ID（可选）
*  功能：获取指定元素对象的集合
*/
function getTagNames(kname,pid){
    if(arguments.length === 1){
        return document.getElementsByTagName(kname);
    }
    else if(arguments.length === 2){
        return getId(pid).getElementsByTagName(kname);
    }
    else{
        alert("参数错误");
    }
}

/*
*  addEvent函数
*  参数kid：元素ID
*  参数ktype：事件类型
*  参数fn： 回调函数
*  功能：兼容IE6-8浏览器，封装事件绑定
*/
