如何正确使用document.querySelectorAll

Question

我有这段代码，当用户按ESC按钮时，需要js隐藏模态窗口，当用户单击窗口外时，问题是该函数只适用于第一个模态窗口，而不适用于第二个模式窗口，因为document.querySelector只使用该类选择第一个div。

不幸的是，当我尝试使用document.querySelectorAll时，函数停止工作。您可以使用下面的代码片段进行测试。

我该怎么办？如何正确使用document.querySelectorAll？

​

function modalClose() {
    if (location.hash == '#spedizione-resi' || location.hash == '#soddisfatti-rimborsati') {
        location.hash = '';
    }
}

// ESC
document.addEventListener('keyup', function(e) {
    if (e.keyCode == 27) {
        modalClose();
    }
});

var modal = document.querySelector('.modal-window');
modal.addEventListener('click', modalClose, false);

modal.children[0].addEventListener('click', function(e) {
    e.stopPropagation();
}, false);

.modal-window {
  position: fixed;
  background-color: rgba(0, 0, 0, 0.65);
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 999999;
  opacity: 0;
  pointer-events: none;
  transition: all 0.3s;
}

.modal-window svg {
  width: 30px;
  margin: 15px;
  fill: #00a5cb;
}

.modal-window:target {
  opacity: 1;
  pointer-events: auto;
}

.modal-window>div {
  width: 90%;
  max-width: 600px;
  max-height: 400px;
  border-radius: 3px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  padding: 1em;
  background: #ffffff;
  color: #333333;
  text-align: left;
  line-height: 1.25em;
}

.modal-window>div>div {
    overflow: auto;
    max-height: 200px;
}

.modal-window header {
  font-weight: bold;
}

.modal-window h1 {
  font-size: 150%;
  margin: 25px 0px 15px 0px;
  color: #333333;
}

.modal-close {
  position: absolute;
  right: 0;
  text-align: center;
  top: 0;
} 

<div id="spedizione-resi" class="modal-window">
  <div>
    <a href="#" title="Chiudi" class="modal-close">X</a>
    <h1>{{ settings.resi_bar_text }}</h1>
    <div>{{ settings.resi_bar_content }}</div>
  </div>
  </div>

<div id="soddisfatti-rimborsati" class="modal-window">
  <div>
    <a href="#" title="Chiudi" class="modal-close">X</a>
    <h1>{{ settings.rimb_bar_text }}</h1>
    <div>{{ settings.rimb_bar_content }}</div>
  </div>
  </div>
  
  <a href="#spedizione-resi">Modal 1</a>
    <a href="#soddisfatti-rimborsati">Modal 2</a>

您需要迭代集合。

​

function modalClose() {
  if (location.hash == '#spedizione-resi' || location.hash == '#soddisfatti-rimborsati') {
    location.hash = '';
  }
}

// ESC
document.addEventListener('keyup', function(e) {
  if (e.keyCode == 27) {
    modalClose();
  }
});
// Changed here
var modal = document.querySelectorAll('.modal-window');
modal.forEach(function(item) {
  item.addEventListener('click', modalClose, false);
  item.children[0].addEventListener('click', function(e) {
    e.stopPropagation();
  }, false);
})

.modal-window {
  position: fixed;
  background-color: rgba(0, 0, 0, 0.65);
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 999999;
  opacity: 0;
  pointer-events: none;
  transition: all 0.3s;
}

.modal-window svg {
  width: 30px;
  margin: 15px;
  fill: #00a5cb;
}

.modal-window:target {
  opacity: 1;
  pointer-events: auto;
}

.modal-window>div {
  width: 90%;
  max-width: 600px;
  max-height: 400px;
  border-radius: 3px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  padding: 1em;
  background: #ffffff;
  color: #333333;
  text-align: left;
  line-height: 1.25em;
}

.modal-window>div>div {
  overflow: auto;
  max-height: 200px;
}

.modal-window header {
  font-weight: bold;
}

.modal-window h1 {
  font-size: 150%;
  margin: 25px 0px 15px 0px;
  color: #333333;
}

.modal-close {
  position: absolute;
  right: 0;
  text-align: center;
  top: 0;
}

<div id="spedizione-resi" class="modal-window">
  <div>
    <a href="#" title="Chiudi" class="modal-close">X</a>
    <h1>{{ settings.resi_bar_text }}</h1>
    <div>{{ settings.resi_bar_content }}</div>
  </div>
</div>

<div id="soddisfatti-rimborsati" class="modal-window">
  <div>
    <a href="#" title="Chiudi" class="modal-close">X</a>
    <h1>{{ settings.rimb_bar_text }}</h1>
    <div>{{ settings.rimb_bar_content }}</div>
  </div>
</div>

<a href="#spedizione-resi">Modal 1</a>
<a href="#soddisfatti-rimborsati">Modal 2</a>
