模态窗口不会关闭

Question

这是我之前的主题中的后续问题 Creating Multiple Modals on a Single Page

在以下建议中，它们都完美地工作，我假设我可以在与按钮元素相对的图像上进行模态工作，但似乎并非如此。我可以完全打开模态然而×不会触发模态的关闭，我无法弄清楚为什么。我禁用了附加到我页面的所有CSS，假设有些东西干扰了它，但我对相同的结果很有趣，所以我有理由相信问题在javascript中？有人会有任何想法如何解决它？感谢。

// Get the modal
    var modal = document.getElementsByClassName('modal');

    // Get the button that opens the modal
    var btn = document.getElementsByClassName("myBtn");


    // Get the <span> element that closes the modal
    var span = document.getElementsByClassName("close");

    // When the user clicks the button, open the modal 
    btn[0].onclick = function() {
    modal[0].style.display = "block";
    }

    btn[1].onclick = function() {
    modal[1].style.display = "block";
    }

你的问题是关闭模态的跨度是在＆＃34;按钮＆＃34;的div内部。打开模态。

当点击事件在跨度上触发时，它也会在父div上触发。因此，模态会立即隐藏，然后重新显示。

要解决此问题，请确保将按钮的div与模式的div分开：

＆＃13;

＆＃13;

// Get the modal
var modal = document.getElementsByClassName('modal');

// Get the button that opens the modal
var btn = document.getElementsByClassName("myBtn");


// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close");

// When the user clicks the button, open the modal 
btn[0].onclick = function() {
modal[0].style.display = "block";
}

btn[1].onclick = function() {
modal[1].style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span[0].onclick = function() {
modal[0].style.display = "none";
}

span[1].onclick = function() {
modal[1].style.display = "none";
}
    
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
    modal.style.display = "none";
}
}
