如何制作这样的多个按钮/ID？基于检查的解决方案。 ——
function showme(id)
var divid = document.getElementById(id);
var clicky = document.getElementById("clicky");
if (divid.style.display == 'block')
divid.style.display = 'none';
clicky.innerhtml = "MORE";

divid.style.display = 'block';
clicky.innerHTML = "LESS";

【参考方案1】：function showme(id)
var car = document.createElement('i');
car.classList.add("fa");
var divid = document.getElementById(id);
var clicky = document.getElementById("clicky");
if (divid.style.display == 'block')
divid.style.display = 'none';
clicky.innerHTML = "MORE";
car.classList.add("fa-arrow-down");
else
divid.style.display = 'block';
clicky.innerHTML = "LESS";
car.classList.add("fa-arrow-up");
clicky.appendChild(car);

但是如何让显示两个不同的图标呢？例如更多（向下箭头）和更少（向上箭头）？【参考方案2】：你可以这样做......
function showme(id)
var divid = document.getElementById(id);
var clicky = document.getElementById("clicky");
if (divid.style.display == 'block')
divid.style.display = 'none';
clicky.innerHTML = "MORE <i class='fa fa-arrow-down'></i>";
else
divid.style.display = 'block';
clicky.innerHTML = "LESS <i class='fa fa-arrow-up'></i>";

是的！干得好！【参考方案3】：请更改您的 JS 代码，如下所示：-
function showme(id)
var divid = document.getElementById(id);
var clicky = document.getElementById("clicky");
if (divid.style.display == 'block')
divid.style.display = 'none';
clicky.innerHTML = 'MORE <i class="fa fa-car"></i>';
else
divid.style.display = 'block';
clicky.innerHTML = 'LESS <i class="fa fa-car"></i>';
