Javascript 单击锚定标记时自动转到页面顶部

我有个问题

我将页面滚动到中间。当我单击右侧的a标记以显示

div

时，页面将自动滚动到页面顶部。我想防止这种情况发生

请帮忙！ 谢谢

我的src代码：

-html

<div id="container">
<a href="#">
<img 
onclick="showCustom()"id="setting"src="https://images.unsplash.com/photo157530259766162aae7fe1447? 
ixlib=rb- 
1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjE0NTg5fQ">
</a>
<div id="custom"  class="custom-1">

</div>

</div>

-Js

  #custom {
position: fixed;
width: 100px;
height: 200px;
right: 20px;
top: 100px;
background-color: white;
transition: 0.8s;
border-radius: 20px;

}
.custom-1 {

right: -150px !important;


}
#setting {
position: fixed;
width: 30px;
z-index: 99;
right: 30px;
top: 50px;
background-color: rgb(255, 255, 255);
padding: 5px;
border-radius: 15px;
}

#container {
background-color:black;
width:100%;
height:2000px;
}

var btnsetting = document.getElementById("setting");
function showCustom() {
var x = document.getElementById("custom");
if (x.className == "" ) {

    x.className = "custom-1";

}

else{


    x.className = "";


}}

欢迎来到SO

使用

JavaScript:Void（0）href

替换

 <a href="JavaScript:Void(0);">
<img 
onclick="showCustom()"id="setting"src="https://images.unsplash.com/photo157530259766162aae7fe1447? 
ixlib=rb- 
1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjE0NTg5fQ">
</a>

Ref

您应该删除“a”元素，并使用cursor:pointer实现相同的效果
