>我正在使用W3学校的模态示例 对于同一页面上的两个按钮,每个按钮都会打开不同的模式。
问题是当用户单击模态外部时控制模态关闭的功能仅适用于一个模态,而不适用于第二个模态。
我尝试了很多选择,但似乎没有一个有效。
我试图为 if 条件添加 OR 语句,但没有任何结果:
window.onclick = function(event) {
if ((event.target == modal) || (event.target == modall)) {
modal.style.display = "none";
}
}
我也尝试为每个模态编写单独的函数:
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
window.onclick = function(event) {
if (event.target == modall) {
modall.style.display = "none";
}
}
你知道我哪里漏了重点吗?
非常感谢所有的帮助,期待。
这可能很简单,但它适用于我。
// Get the modal
var modal1 = document.getElementById("myModal1");
var modal2 = document.getElementById("myModal2");
// Get the button that opens the modal
var btn1 = document.getElementById("myBtn1");
var btn2 = document.getElementById("myBtn2");
// Get the <span> element that closes the modal
var span1 = document.getElementsByClassName("close")[0];
var span2 = document.getElementsByClassName("close second")[0];
// When the user clicks the button, open the modal
btn1.onclick = function() {
modal1.style.display = "block";
}
btn2.onclick = function() {
modal2.style.display = "block";

Node.contains
可以实现你的目标,这里是MDN的摘录
Node.contains(( 方法返回一个布尔值,指示是否 节点是否是给定节点的后代。
语法节点.包含( otherNode (
我附上了一个示例来演示它在实践中是如何工作的
// Get the modal
var modal1 = document.getElementById('modal-1');
var modal2 = document.getElementById('modal-2');
// Get the button that opens the modal
var btn1 = document.getElementById("modal-1-button");

// When the user clicks the button, open the modal
btn1.onclick = function(event) {
event.preventDefault();
event.stopPropagation();
modal1.style.display = "block";
}
btn2.onclick = function(event) {
event.preventDefault();
event.stopPropagation();
modal2.style.display = "block";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function (event) {
var modal1 = document.getElementById("modal-1");
