为什么我不能让div改变onclick？

我试着创建一个非常简单的网站，我只想在我点击顶部的相应列表按钮时更改两个div。但是，当我点击第二个列表按钮时，第二个div永远不会出现。无法弄清楚为什么现在几个小时，代码中的所有步骤看起来都是合乎逻辑的。我想在没有Jquery或其他任何东西的情况下这样做。

＆＃13;
＆＃13; 
window.onload = function() {
d1 = document.getElementById('myDiv1');
d2 = document.getElementById('myDiv2');
function showDiv1() {
  if( d2.style.display == "block" )
  {
    d2.style.display = "none";
    d1.style.display = "block";
  }
  else
  {
    return false;
  }
}

function showDiv2() {
  if( d1.style.display == "block" )
  {
    d1.style.display = "none";
    d2.style.display = "block";
  }
  else
  {
    return false;
  }
}
}
＆＃13;

 d1 = document.getElementById('myDiv1');
 d2 = document.getElementById('myDiv2');

getElementById接受一个字符串。你错过了单引号。

此外，Javascript中没有pass。它应该是return false

答案 1 :(得分：0)

首先更改getElementsById（＆＃39; whateverTheIdIs＆＃39;）：

d1 = document.getElementById('myDiv1');
d2 = document.getElementById('myDiv2');

将onClick事件绑定到相应的元素：

<li class="li1 hvr-grow"  ><a href="#sport" onclick="showDiv1()">SPORT</a>
</li>
<li class="li1 hvr-grow"><a href="#sportler" onclick="showDiv2()">SPORTLER</a>
</li>

第三次在showDiv1和showDiv2函数末尾返回false以防止链接被应用

答案 2 :(得分：0)

当你的js代码执行时，这个元素可能不存在 解决那个问题 只需将你的js脚本存储在onload事件

中 
window.onload = function() {

    d1 = document.getElementById('myDiv1');
    d2 = document.getElementById('myDiv2');
    function showDiv1() {
       if( d2.style.display == "block" )
       {
          d2.style.display = "none";
          d1.style.display = "block";
       }
       else
       {
          pass;
       }
    }

    function showDiv2() {
       if( d1.style.display == "block" )
       {
          d1.style.display = "none";
          d2.style.display = "block";
       }
       else
       {
          pass;
       }
    }
}

答案 3 :(得分：0)

双等于符号＆＃39; ==＆＃39;在功能上是问题。它应该只是一个＆＃39; =＆＃39;。现在即使不使用上述任何建议也能正常工作。谢谢大家：）
