仅使用CSS关闭模态

Question

我只需要使用以下CSS来关闭模态：http : //jsfiddle.net/raving/1mhsynmw/

但是，我无法使其正常工作。我的模态如下。

function alert(msg) {
	document.getElementById("alert").innerHTML = '<div class="modal-overlay"><div class="modal"><div class="modal-container"><h3>' + msg + '</h3><p>' + msg + '</p></div><p class="modal-footer"><a href="javascript:" id="ok">OK</a></p></div>';
}

alert("This is some text to show you this modal. This is some text to show you this modal. This is some text to show you this modal. This is some text to show you this modal.");

body {
  font-family:arial;
  font-size:11px;
}
.modal {
     position: fixed;
     top: 20px;
     margin-left: auto;
     margin-right: auto;
     left: 0;
     right: 0;
     width: 200px;
     box-shadow: 0 4px 6px 1px rgba(50, 50, 50, 0.14);
     background: #fff;
}
.modal p {
	 cursor:default;
}
.modal-container {
	 padding: 10px;
}
.modal p a {
	 color:#555;
}
.modal-footer a {
	 display:block;
	 border:1px solid #eee;
	 width:9.5%;
	 padding:3px;
	 background:#fff;
	 text-decoration:none;
	 float:right;
}
.modal-footer {
     background: #fafafa;
     border-top: 1px solid #eee;
     margin-bottom: 0px;
	 margin-top:0px;
	 padding:8px;
	 height:25px;
}
.modal h3 {
	 margin:0px;
	 white-space: nowrap;
     overflow: hidden;
     text-overflow: ellipsis;
     max-width: 175px;
}
.modal-last {
	 padding-bottom:0px;
}
.modal-overlay:before {
     content: '';
     position: fixed;
     top: 0px;
     left: 0px;
     width: 100%;
     height: 100%;
     background: rgba(0, 0, 0, 0.5);
}

<div id="alert"></div>

<h3>Content..</h3>
<p>Just to show it's a modal</p>

问题：是否有任何方法可以在不使用Javascript的情况下关闭模式？而且这是不可能的，如何使用Javascript来关闭此模式？

Answer 1

如果您不想在单击“确定”按钮时使用 JQuery 关闭模式，则可以使用纯 JavaScript 执行类似于以下代码的操作。您必须为选择器分配一个索引才能使其正常工作。

    //begin click event
    document.getElementById("ok").addEventListener("click",function(event){


    /* Hide the element with a class name of modal.
       note:If there is more than one element with the class name
       modal then this code will only select the first one in the
       collection of elements 
    */

    document.getElementsByClassName("modal")[0].style.display = "none";


       });//end click event
