我的 HTML 代码具有以下结构:
<a class='card'...<a/>
<div id = "divone" class="card__background" ... </div>
有四张各自的卡片。
当点击 class='card' 的 div 之一时。 JavaScript 代码应该将 'class="card__background"隐藏在其他 class='card' div 中。我已经有一个不起作用的脚本代码。
为什么会这样？
我正在寻求修复我的 JavaScript 代码以使其正常工作
function imagechange(divid) {
var x = document.getElementById(divid);
if (x == "divone") {
x.style.display = "block";
divtwo.style.display = 'none';
divthree.style.display = 'none';
divfour.style.display = 'none';
} else if (x == "divtwo";) {
x.style.display = "block";
divone.style.display = 'none';
divthree.style.display = 'none';
divfour.style.display = 'none';
} else if (x == "divthree";) {
x.style.display = "block";
divone.style.display = 'none';
divtwo.style.display = 'none';
divfour.style.display = 'none';
} else {
x.style.display = "block";
divone.style.display = 'none';
divtwo.style.display = 'none';
divthree.style.display = 'none';
}

当您使用 var x = document.getElementById(divid); 时，您将获得一个对象。所以你的条件永远不会成立。
如果您想检查 id，只需将条件更改为:
function imagechange(divid) {
const x = document.getElementById(divid)
const id = x.id
if (id === 'divone') {
x.style.display = 'block'
divtwo.style.display = 'none'
divthree.style.display = 'none'
divfour.style.display = 'none'
}
else if (id === 'divtwo') {
x.style.display = 'block'
divone.style.display = 'none'
divthree.style.display = 'none'
divfour.style.display = 'none'
}
else if (id === 'divthree') {
x.style.display = 'block'
divone.style.display = 'none'
divtwo.style.display = 'none'
divfour.style.display = 'none'
}
else {
x.style.display = 'block'
divone.style.display = 'none'
divtwo.style.display = 'none'
divthree.style.display = 'none'
}
}
