如何使用锚标记而不是按钮来触发模态?我无法使用Bootstrap,因为我需要修改模态的大小。我尝试将ID放入href,但这并没有帮助。有什么建议?
// 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";
}
}

<!-- 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>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
</div>
</div>

如果您只是将现有的<button>
代码更改为<a>
,那么您现有的JS代码应该可以运行。原理完全相同,通过ID获取元素的引用,然后附加一个单击处理程序。
但是为了让锚点显示为链接它需要一个href,所以我使用了href="#"
,然后更新了click函数以取消默认的点击行为。
你可能也想要一些CSS最初隐藏模态。
// 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(e) {
e.preventDefault(); // ADDED this line
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";
}
}
#myModal { display: none; } /* added this CSS */
<!-- Trigger/Open The Modal -->
<a id="myBtn" href="#">Open Modal</a> <!-- changed tags, added href, kept id -->
<!-- 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>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
</div>
</div>
</div>
