javascript-在单个页面上创建多个模态
作者:互联网
根据w3schools.com的示例代码,我在单个网页上创建多个模式时遇到一些问题.我正在使用的有问题的代码是以下代码:http://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal2
我找到了与此问题类似的话题,但是在jsfiddle中尝试该解决方案后,我仍然没有结果,有人有任何想法吗?

<h2>1st Modal</h2>
<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<div class="modal-header">
<span class="close">×</span>
<h2>Modal Header</h2>
</div>
<div class="modal-body">
<p>Some text in the Modal Body</p>
<p>Some other text...</p>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
</div>
</div>
<h2>2nd Modal</h2>
<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<div class="modal-header">
<span class="close">×</span>
<h2>Modal Header</h2>
</div>
<div class="modal-body">
<p>Some text in the Modal Body</p>
<p>Some other text...</p>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
脚本:
// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// 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";
}
}
解决方法:
在您的JSFiddle上,确保使用class =“ myBtn”而不是id =“ myBtn”,然后它应该可以工作.
这是完整的工作代码:
HTML:
<h2>1st Modal</h2>
<!-- Trigger/Open The Modal -->
<button class="myBtn">Open Modal</button>
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<div class="modal-header">
<span class="close">×</span>
<h2>Modal Header</h2>
</div>
<div class="modal-body">
<p>Some text in the Modal Body</p>
<p>Some other text...</p>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
</div>
</div>
<h2>2nd Modal</h2>
<!-- Trigger/Open The Modal -->
<button class="myBtn">Open Modal</button>
<!-- The Modal -->
<div id="myModal2" class="modal">
<!-- Modal content -->
<div class="modal2-content">
<div class="modal-header">
<span class="close">×</span>
<h2>Modal Header</h2>
</div>
<div class="modal-body">
<p>Some text in the Modal Body</p>
<p>Some other text...</p>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
</div>
</div>
JS:
// 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";
}
}
