javascript - 获取触发事件的元素的 id

Question

我试图通过单击一个区域来创建一个模式，然后根据单击的区域以不同的方式对其进行修改。我遇到了一个停顿，因为我为所有区域提供了相同的 id，这意味着我的代码只会使用第一个区域的数据修改模式。有没有办法，在给每个区域一个唯一的 id 之后，把它放在函数中？

$("#ModArea").click(function() {
  var name = $(this).attr('title');
  $("#country_name").html(name);
});

/* The Modal (background) */

.modal fade {
  display: none;
  /* Hidden by default */
  position: fixed;
  /* Stay in place */
  z-index: 1;
  /* Sit on top */
  padding-top: 100px;
  /* Location of the box */
  left: 0;
  top: 0;
  width: 100%;
  /* Full width */
  height: 100%;
  /* Full height */
  overflow: auto;
  /* Enable scroll if needed */
  background-color: rgb(0, 0, 0);
  /* Fallback color */
  background-color: rgba(0, 0, 0, 0.4);
  /* Black w/ opacity */
}


/* Modal Content */

.modal-content {
  position: relative;
  background-color: #fefefe;
  margin: auto;
  padding: 0;
  border: 1px solid #888;
  width: 80%;
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 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: #5cb85c;
  color: white;
}

.modal-body {
  padding: 2px 16px;
}

                    </div>
                </div>
            </div>
        </div>
</map>

现在，如果我点击爱尔兰，它会创建一个标题为空的模式，而如果我点击冰岛，或者在点击冰岛后点击爱尔兰，它会创建一个以“冰岛”作为图块的模式。
