JS之setAttribute和getAttribute

1.ele.getAttribute(attributeName);

 返回元素的指定属性值，如果元素没有该属性，则返回null

2.ele.setAttribute(attributeName,value);

3.在IE 7以及更早版本部分属性的设置应使用另外的名称，为了兼容IE

<script>      dom=(function(){      var fixAttr={         tabindex:'tabIndex',         readonly:'readOnly',         'for':'htmlFor',         'class':'className',         maxlength:'maxLength',         cellspacing:'cellSpacing',         cellpadding:'cellPadding',         rowspan:'rowSpan',         colspan:'colSpan',         usemap:'useMap',         frameborder:'frameBorder',         contenteditable:'contentEditable'      },          //模拟设置attribute,      div=document.createElement('div');     div.setAttribute('class','t');         var supportSetAttr = div.className === 't';          return {          setAttr:function(el, name, val){            el.setAttribute(supportSetAttr ? name : (fixAttr[name] || name), val);          },          getAttr:function(el, name){            return el.getAttribute(supportSetAttr ? name : (fixAttr[name] || name));          }       }    })();        window.onload=function(){        var mydiv=document.getElementById("d1");        dom.setAttr(mydiv, 'class', 'bg');    }  </script>
