Question

我正在为用户单击我的三个按钮中的任何一个创建模态，当前它仅适用于第一个按钮，但是当我关闭模态并单击另一个按钮时，模态不会打开，并且我无法找出原因。无论关闭后我单击哪个按钮，如何使模态打开？

这是我的html：

<div class="modal" id="modal">
                        <button id="close">X</button>
                        <h5>Modal</h5>
                      
                      </div>
                    <div class="column-container">
                        <div class="first-column">
                                <h3>Affiliate Manager</h3>
                                <br>
                                <p>

                            </div>
                                <div class="second-column">
                                   <button class="apply-btn jsModalTrigger open">APPLY NOW</button>
                              </div>
                              <div class="first-column">
                                <h3>Affiliate Manager</h3>
                                <br>
                                <p>

                            </div>
                                <div class="second-column">
                                   <button class="apply-btn jsModalTrigger open">APPLY NOW</button>
                              </div>
                              <div class="first-column">
                                <h3>Affiliate Manager</h3>
                                <br>
                                <p>

                            </div>
                                <div class="second-column">
                                   <button class="apply-btn jsModalTrigger open">APPLY NOW</button>
                              </div>

我的CSS：

.modal {
    width: 300px;
    height: 150px;
    margin: auto auto;
    background: #34495e;
    display: none;
  }
  
  .modal button {
    right: 0;
    top: 0;
  }

和我的JavaScript：

var btnOpen = document.querySelector(".open");
var btnClose = document.getElementById("close");
var modal = document.getElementById("modal");

btnOpen.onclick = function(){
  modal.style.display = "block";
}

btnClose.onclick = function(){
  modal.style.display = "none";
}

Answer 1

您只是在dom中获得了className为open的第一个元素。更改此：

var btnOpen = document.querySelector(".open");

到以下内容：

var btnsOpen = document.querySelectorAll(".open");

这将返回一个元素数组。

然后，您必须遍历该数组并添加事件

btnsOpen.forEach(btn=>{
      btn.onclick = function(){
      modal.style.display = "block";
    }
 })

var btnsOpen = document.querySelectorAll(".open");
var btnClose = document.getElementById("close");
var modal = document.getElementById("modal");

btnsOpen.forEach(btn=>{
  btn.onclick = function(){
  modal.style.display = "block";
}
})


btnClose.onclick = function(){
  modal.style.display = "none";
}

<div class="modal" id="modal">
                        <button id="close">X</button>
                        <h5>Modal</h5>
                      
                      </div>
                    <div class="column-container">
                        <div class="first-column">
                                <h3>Affiliate Manager</h3>
                                <br>
