一个<li>可以document.getElementById("")控制，多了怎么办呢？

javascriptdiv lidivli

解决方案 »

  1.   

    getElementsByTagName
    getElementByClass
      

  2.   

    一个页面id只能是唯一的一个  相同多的用class去定义
      

  3.   

    ohmygirl#     根据您的提示，找到了很多这样的：
     //[email protected]*****getElementsByTagName 
    function tag(name,elem){ 
          if(!document.getElementsByTagName) 
                return false; 
         return (elem || document).getElementsByTagName(name);然后我写了一个这样的：li = document.getElementsByTagName('li');
    for(var i=0;i<li.length;i++)
    {
        li[i].onMouseOver=function()
        {
            this.style.backgroundColor="blue";
        }
        li[i].onMouseOut=function()
        {
            this.style.backgroundColor="green";
        }
    }
    并不成功！
     
    ohmygirl#     可以说得详细点吗？新手不是很明白！
