如何控制显示和隐藏？

Question

<table id="tab1" style="display:none"> 
不带分号试试，带分号好像是css文件里的写法。

Answer 1

大哥,你看看你的JAVASCRIPT
             if(obj1.style.display=="none"){ 
                              obj1.style.display=""; 
                              obj2.style.diaplay="none"; 
              }else{ 
                              obj1.style.display="none"; 
                                obj2.style.diaplay=""; 
          } 
 obj2.style.diaplay="none"; ??????????
 obj2.style.display="none";
