<script type="text/javascript" src="modalBox.js"></script>

</html>JS:
(function() {
/*建立模态框对象*/
var modalBox = {};
/*获取模态框*/
modalBox.modal = document.getElementById("myModal");
/*获得trigger按钮*/
modalBox.triggerBtn = document.getElementById("triggerBtn");
/*获得关闭按钮*/
modalBox.closeBtn = document.getElementById("closeBtn");
/*模态框显示*/
modalBox.show = function() {
console.log(this.modal);
this.modal.style.display = "block";
}
/*模态框关闭*/
modalBox.close = function() {
this.modal.style.display = "none";
}
/*当用户点击模态框内容之外的区域，模态框也会关闭*/
modalBox.outsideClick = function() {
var modal = this.modal;
window.onclick = function(event) {
if(event.target == modal) {
modal.style.display = "none";
}
}
}
/*模态框初始化*/
modalBox.init = function() {
var that = this;
this.triggerBtn.onclick = function() {
that.show();
}
this.closeBtn.onclick = function() {
that.close();
}
this.outsideClick();
}
modalBox.init();
})();CSS:

background-color: rgba(0,0,0,0.4); /* 背景色 */
}
/*模态框内容*/
.modal-content {
display: flex; /*采用flexbox布局*/
flex-direction: column; /*垂直排列*/
position: relative;
background-color: #fefefe;
