Question

所以我有这个网站，我正在尝试使用模态作为我的登录并注册 - 但我无法让它们工作。

它与我的z索引有什么关系，或者为什么它们没有触发？当我点击我的链接时，绝对没有任何反应 - 是因为它们不是按钮吗？

我已经包含了我的HTML，CSS和JavaScript。

</body>

CSS

.modal {
  display: none;
  position: fixed;
  z-index: 8888;
  left: 0;
  top: 0;
  width: 100%;
  height: 100vh;
  overflow: auto;
  background-color: rgb(0, 0, 0);
  background-color: rgba()0, 0, 0, .4;
}

.modal-content {
  background-color: #fefefe;
  margin: 10vh auto;
  padding: 2em;
  border: .25em solid #888;
  width: 90%;
}

@media (min-width:60rem) {
  .modal-content {
      width: 30%;
  }
}

.close {
  color: #aaa;
  float: right;
  font-size: 2em;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: black;
  text-decoration: none;
  cursor: pointer;
}

这是我的JavaScript

var modalBtns = [...document.querySelectorAll(".button")];
modalBtns.forEach(function (btn) {
    btn.onclick = function () {
        var modal = btn.getAttribute('data-modal');
        document.getElementById(modal).style.display = "block;"
    }
});

var closeBtns = [...document.querySelectorAll(".close")];
closeBtns.forEach(function (btn) {
    btn.onclick = function () {
        var modal = btn.closest('.modal');
        modal.style.display = "none";
    }
});

window.onclick = function (event) {
    if (event.target.className === "modal") {
        event.target.style.display = "none";
    }
}

Answer 1

你刚才放错了结束语。请更新您的代码，如下所示：

var modalBtns = [...document.querySelectorAll(".button")];
modalBtns.forEach(function(btn){
    btn.onclick = function(e) {
    e.preventDefault();
       var modal = btn.getAttribute('data-modal');
       document.getElementById(modal).style.display = "block";
    }
});

var closeBtns = [...document.querySelectorAll(".close")];
closeBtns.forEach(function(btn){
  btn.onclick = function() {
    var modal = btn.closest('.modal');
    modal.style.display = "none";
 }
});

window.onclick = function(event) {
  if (event.target.className === "modal") {
   event.target.style.display = "none";
 }
}

Answer 2

正如@Kaddath所说：

document.getElementById（modal）.style.display =“block;”应该是“阻止”而不用分号，这是你的错误.. - Kaddath

非常感谢！
