javascript - 如何修复简单的 Javascript 下拉错误？

Question

我在使用此下拉菜单时遇到问题，我正在为客户编辑代码，并将下拉菜单组从 7 个减少到 3 个，这是我的 code

我想要做的是激活第三个下拉菜单并添加 css，以便在下拉时圆边消失

我知道这与这里的脚本有关:

function toggleGroup(group){
                    var isShown = document.getElementById("group"+group).style.display;


                    if (!isShown || isShown=="none"){

                        for (i = 1; i < 4; i++) {

                            if (i != group){
                                document.getElementById("group"+i).style.display="none";
                                document.getElementById("toggle"+i).src ="img/moreIcon.png";    
                                location.hash = "#myAnchor";                
                                    if(i=="3"){
                                    document.getElementById("backgroundSpeech").style.borderRadius="0 0 20px 20px";
                                    }
                            }
                            else{
                                document.getElementById("group"+i).style.display="block";
                                document.getElementById("toggle"+group).src ="img/lessIcon.png";    
                                location.hash = "#myAnchor";    
                                if(group=="3"){
                                    document.getElementById("backgroundSpeech").style.borderRadius="0px";
                                    }                   

                            }   
                        }
                    }   

                    else{
                                document.getElementById("group"+group).style.display="none";
                                document.getElementById("toggle"+group).src ="img/moreIcon.png";                        
                                    if(group=="3"){
                                    document.getElementById("backgroundSpeech").style.borderRadius="0 0 20px 20px";
                                    }   
                            }

                }       

        function toggleMy(my){
                    var isShown = document.getElementById(my).style.display;
                    if (!isShown || isShown=="none"){
                        document.getElementById(my).style.display="block";
                        var toWrite = "<a href=\"\javascript:toggleMy('" +my+ "');\"\>read less</a>";
                        document.getElementById("more"+my).innerHTML=toWrite;

}
                    else{
                        document.getElementById(my).style.display="none";
                        var toWrite = "<a href=\"\javascript:toggleMy('" +my+     "');\"\>read more</a>";
                        document.getElementById("more"+my).innerHTML=toWrite;

                    }

                                                }

提前致谢!

我不确定你是否想要完全没有圆 Angular ，但我删除了所有的边框半径

function toggleGroup(group) {
  var isShown = document.getElementById("group" + group).style.display;


  if (!isShown || isShown == "none") {

    for (i = 1; i <= 3; i++) {

      if (i != group) {
        document.getElementById("group" + i).style.display = "none";
        document.getElementById("toggle" + i).src = "img/moreIcon.png";
        location.hash = "#myAnchor";
        if (i == "3") {
          document.getElementById("backgroundSpeech").style.borderRadius = "0 0 0px 0px";
        }
      } else {
        document.getElementById("group" + i).style.display = "block";
        document.getElementById("toggle" + group).src = "img/lessIcon.png";
        location.hash = "#myAnchor";
        if (group == "3") {
          document.getElementById("backgroundSpeech").style.borderRadius = "0px";
        }

      }
    }
  } else {
    document.getElementById("group" + group).style.display = "none";
    document.getElementById("toggle" + group).src = "img/moreIcon.png";
    if (group == "3") {
      document.getElementById("backgroundSpeech").style.borderRadius = "0 0 0px 0px";
    }
  }

}






function toggleMy(my) {
  var isShown = document.getElementById(my).style.display;
  if (!isShown || isShown == "none") {
    document.getElementById(my).style.display = "block";
    var toWrite = "<a href=\"\javascript:toggleMy('" + my + "');\"\>read less</a>";
    document.getElementById("more" + my).innerHTML = toWrite;

  } else {
    document.getElementById(my).style.display = "none";
    var toWrite = "<a href=\"\javascript:toggleMy('" + my + "');\"\>read more</a>";
    document.getElementById("more" + my).innerHTML = toWrite;

  }
