JS库中常用的attr方法
/*
如果传来的参数为html集合，则只取第一个节点进行操作
*/
var attr = function(elem, name, value) {
if (!elem)
return ;
if (elem.length > 1) {
elem = elem[0];
}

为不支持的浏览器添加getElementsByClassName与querySelectorAll方法
/*
document.getElementById();
document.getElementsByTagName();
document.getElementsByName();
以上三种方法在主流浏览器中得到原生支持，但是通过class取得元素以及通过css选择器的方式取得元素，即
getElementsByClassName与querySelectorAll未在IE6、7、8中得到完全支持
