javascript - 点击事件 : divs appear one at a time

Question

是否可以根据这个实际一个div一次做，也就是说onclick这两个事件都打不开，但是如果一个打开另一个被点击第一个自动关闭。顺便说一句，使用此代码的上下文不允许使用 Jquery。感谢您的帮助

<style type="text/css">
  .link{text-decoration:none; color:white;}

  .link:visited{color:white}

.row {
  display: flex; /* equal height of the children */
}

.col {
  flex: 1; /* additionally, equal width */
  
  padding: 1em;
  border: solid;
}

您可以遍历其他元素并在“显示”函数中先关闭它们

function show(id) { 

    var benefits = document.getElementsByClassName("benefits");
    for(var i = 0; i<benefits.length; i++){
        benefits[i].style.display="none";
    }

    if(document.getElementById('b'+id).style.display=='none') { 
        document.getElementById('b'+id).style.display='block'; 
    } 

    return false;
}
