margin:0 auto;
border: 1px solid red;
font:12px;
}

.top{
width:1245px;
height:100px;
border: 1px solid red;
}

.kehu{
margin-left:80px;
width:250px;
background-color: gray;
height:100px;
float: left;
}

.zhuti{
margin-left:40px;

float: left;
}

.anniu{

height:100px;
float: left;

.anniu ul{
list-style-type: none;
padding: 0px;

/*.anniu ul li{
position: absolute;

.div1{
margin-left:50px;
margin-top:150px;
height: 500px;
width: 800px;
border: 2px solid blue;
background-image: url("images/d1.jpg");

.div2{

height: 500px;

background-image: url("images/d4.jpg");
display: none;
}

当我点击上面的几个按钮的时候想要让div1、div2、div3和div4在指定的位置上面跳转只有第一个按钮可以，老是报错说缺少对象

[解决办法]

HTML code

</div>  <div class="div1" id="div1"></div>  <div class="div2" id="div1"></div>  <div class="div3" id="div1"></div>  <div class="div4" id="div1"></div>  </div>
[解决办法]
document.getElementById('div1') 这个是根据id属性获取的 不是class属性
[解决办法]
  楼上已经把原因说了，这样改就好
 <div class="div1" id="div1"></div>
 <div class="div2" id="div2"></div>
 <div class="div3" id="div3"></div>
 <div class="div4" id="div4"></div>
