当用户在同一页面上有多个模态时单击模态外的任何位置时，如何关闭模态

时间：2017-05-24 08:51:37

标签： javascript jquery html css twitter-bootstrap

我正在使用W3 Schools中的模态示例  对于同一页面上的两个按钮，每个按钮打开不同的模态。

问题是当用户点击它以外时，控制模态关闭的功能仅适用于一个模态但不适用于第二个模态。

我尝试了很多选项，但似乎没有其他选项。

我尝试为 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";
    }
}

你知道我在哪里错过了这一点吗？

非常感谢所有人的帮助，期待。

Node.contains可以实现您的目标，此处摘自MDN

  

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node.contains（otherNode）

我附上了一个例子来说明它在实践中是如何运作的

＆＃13;
＆＃13; 
// 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");
var btn2 = document.getElementById("modal-2-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");
  var modal2 = document.getElementById("modal-2");
  if (modal1.style.display === "block") {
    var modal1Content = modal1.querySelector(".modal-content");
    if (!modal1Content.contains(event.target)) {
      modal1.style.display = "none";
    }    
  }
  if (modal2.style.display === "block") {
    var modal2Content = modal1.querySelector(".modal-content");
    if (!modal2Content.contains(event.target)) {
      modal2.style.display = "none";
    }    
  }
};
＆＃13; 
#modal-1 {
  
  background-color: green;
}

#modal-2 {
 
  background-color: yellow;
}

btn1.onclick = function() {
    modal1.style.display = "block";
}
btn2.onclick = function() {

}

// When the user clicks on <span> (x), close the modal
span1.onclick = function() {
    modal1.style.display = "none";

span2.onclick = function() {
    modal2.style.display = "none";
