封装简单的连缀功能库

通过构造函数封装简单库

function Base(){

    this.elements = [];
    this.getId = function(id){
        this.elements.push(document.getElementById(id));
        return this;
    };
    this.getTagName = function(tag){
        var tagName = document.getElementsByTagName(tag);
        for(var i = 0; i < tagName.length;i++){
            this.elements.push(tagName[i]);
        };
        return this;
    }
  }

在其原型上面添加处理方式，

Base.prototype.css = function(attr,value){
    for(var i = 0;i< this.elements.length;i++){
        this.elements[i].style[attr] = value;
    };
    return this;
  }
  Base.prototype.click = function(fn){
    for(var i = 0;i<this.elements.length;i++){
      this.elements[i].onclick = fn;
    }
    return this;
  }

经过测试没有问题

$().getId("mydiv").css('color','red').click(function(){
    alert(1)
  });

欢迎各位提出问题
