这段代码只能很好地隐藏/显示(Iamhiden)。
HTML:
<nav id="Iamhiden"></nav>
<button id="THeSummoner" onclick="toggle_visibility('Iamhiden');"></button>
CSS:
#Iamhiden{}
#THeSummoner{
width: 30px;
height: 30px;
background-image: url(../Images/mobile-icon-1.png);
background-repeat: no-repeat;
margin: 22px 0px auto 0px;
padding: 0;
border-style: none;
list-style: none;
background-color: transparent;
}
JS:
function toggle_visibility(Iamhiden) {
var e = document.getElementById(Iamhiden);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}

但我不希望它隐藏/显示(Iamhiden)我只想让它改变(THeSummoner)的背景图像。
JS - 2:
function toggle_visibility(Iamhiden) {
var e = document.getElementById(Iamhiden);
if(e.style.display == 'block')
e.style.display = 'none';
**document.getElementById(THeSummoner).style.background-image=url(../Images/mobile-icon-1.png);**
else
e.style.display = 'block';
document.getElementById(THeSummoner).style.background-image=url(../Images/xmnu.png);
}
我尝试过 JS - 2 ,但它根本不起作用。

没有 THeSummoner 变量,因此您必须将元素Id指定为字符串,而不是变量:
document.getElementById('THeSummoner')
现在您可以像这样更改元素的背景图像:
document.getElementById('THeSummoner').style.backgroundImage = "url('type_path_here')";
