Question

我有一个带有多个按钮的网页。这些按钮触发包含内容的模式。每个按钮都与一个具有唯一内容的唯一模式相关联。

问题在于每个按钮都会触发与页面底部最后一个按钮相关联的模式。

每个按钮和模式都有一个唯一的ID，所以我不明白为什么会这样。

这是我用来创建每个按钮的代码。

谢谢您的帮助！

// JS CODE FOR THE FIRST MODAL 

// Get the modal
var modal = document.getElementById('modal-1');

// Get the button that opens the modal
var btn = document.getElementById("button-1");

// Get the <span> element that closes the modal
var span = document.getElementById("close-1");

// When the user clicks the button, open the modal 
btn.onclick = function() {

Answer 1

不是因为您错过添加一些事件stopPropagation吗？

（而且我认为给JS Vaviable“ span”命名是一个坏主意，这是html标记的名称）

应该更清楚地以这种方式进行编码（服务器元素发生相同的事件）

    var ActionCloseID = ['modal', 'button', 'close'];
    document.onclick = function(e) {
        if (ActionCloseID.includes(e.target.id) ) {
            e.stopPropagation();                  
            modal.style.display = "none";
        }
    }

<script>
// JS CODE FOR THE FIRST MODAL

// Get the modal
var modal = document.getElementById('modal-1');

// Get the button that opens the modal
var btn = document.getElementById("button-1");

// Get the <span> element that closes the modal
var span = document.getElementById("close-1");

// Get the modal
var modal2 = document.getElementById('modal-2');

// Get the button that opens the modal
var btn2 = document.getElementById("button-2");

// Get the <span> element that closes the modal
var span2 = document.getElementById("close-2");

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

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.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";
    }else if (event.target == modal2) {
        modal2.style.display = "none";
    }
}
// When the user press ESC key, close the modal
window.onkeydown = function( event ) {
    if ( event.keyCode == 27 ) {
        modal.style.display = "none";
        modal2.style.display = "none";
    }
};

// When the user clicks the button, open the modal
btn2.onclick = function() {
    modal2.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span2.onclick = function() {
    modal2.style.display = "none";
}

请像这样更新您的脚本，这应该可以。
