Question

我正在尝试添加2个或更多按钮来激活只有一个Script / js代码的视频，但第二个按钮不起作用。

我的想法是不要使用大量基本相同的脚本来堆叠或重载我的页面。我知道这是1级超级基础，但我无法在互联网上找到答案。

这是我的代码：

		var modal = document.getElementById('myModal');// Get the modal
		var btn = document.getElementById("myBtn");// Get the button that opens the modal
		var span = document.getElementsByClassName("close")[0];// Get the <span> element that closes the modal
		btn.onclick = function() {modal.style.display = "block";}// When the user clicks the button, open the modal 
		span.onclick = function() {modal.style.display = "none";}// When the user clicks on <span> (x), close the modal
		window.onclick = function(event) {if (event.target == modal) {modal.style.display = "none";}}// When the user clicks anywhere outside of the modal, close it

.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    /* background dark */
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.5); /* Black w/ opacity */
}

/* Modal Content */
.modal-content {
    position: relative;
    background-color: #fefefe;
    margin: auto;
    padding: 0;
    border: 1px solid black;
    text-shadow: 0px 0px;
    box-shadow: 0 11px 11px 0 rgba(0,0,0,0.4),0 16px 20px 0 rgba(0,0,0,0.19);
    -webkit-animation-name: animatetop;
    -webkit-animation-duration: 0.4s;
    animation-name: animatetop;
    animation-duration: 0.4s
}

/* Add Animation */
@-webkit-keyframes animatetop {
    from {top:-300px; opacity:0} 
    to {top:0; opacity:1}
}

@keyframes animatetop {
    from {top:-300px; opacity:0}
    to {top:0; opacity:1}
}

/* The Close Button */
.close {
    color: white;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: #000;
    text-decoration: none;
    cursor: pointer;
}

.modal-header {
    padding: 2px 16px;
    background-color: #515c70;
    color: white;
}

.modal-body {padding: 12px 16px;} /* video frame */

.modal-footer {
    padding: 2px 16px;
    background-color: #515c70;
    color: white;


#myVideo {
    position: fixed;
    right: 0;
    bottom: 0;


}

我建议给你的按钮一个类和一个数据属性来指定它将触发的目标。

类似的东西：

<button class="js-toggle" data-target="#modal-1">Button 1</button>
<button class="js-toggle" data-target="#modal-2">Button 2</button>

<div id="modal-1">Modal 1</div>
<div id="modal-2">Modal 2</div>

<script>
$('.js-toggle').on('click', function() {
  var target = $(this).data('target');
  $(target).toggleClass('is-active');
});
</script>

一个js脚本，用于多个ID或按钮
