这是一个简单的 JavaScript 示例：

var modal = document.getElementById('modal');
var shade = document.getElementById('shade');
document.getElementById('start').onclick = function() {
  modal.style.display = shade.style.display = 'block';
};
document.getElementById('close').onclick = function() {
  modal.style.display = shade.style.display = 'none';
};

// This code is a workaround for IE6's lack of support for the
// position: fixed style.
//
if (!('maxHeight' in document.body.style)) {
  function modalsize() {
    var top = document.documentElement.scrollTop;
    var winsize = document.documentElement.offsetHeight;
    var docsize = document.documentElement.scrollHeight;
    shade.style.height = Math.max(winsize, docsize) + 'px';
    modal.style.top = top + Math.floor(winsize / 3) + 'px';
  };
  modal.style.position = shade.style.position = 'absolute';
  window.onscroll = window.onresize = modalsize;
  modalsize();
}
body {
  margin: 0;
}

#shade,
#modal {
  display: none;
}

#shade {
  position: fixed;
  z-index: 100;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

#modal {
  position: fixed;
  z-index: 101;
  top: 33%;
  left: 25%;
  width: 50%;
}

#shade {
  background: silver;
  opacity: 0.5;
  filter: alpha(opacity=50);
}
<div id="shade"></div>
<div id="modal">
  <textarea rows="5" cols="25"></textarea>
  <button id="close">Close</button>
</div>

<p>
  <button id="start">Start</button>
</p>

您可以从那里进行各种改进，例如 iframe hacks 以修复 IE z-indexing，或将其封装在可重用对象中，但这是完成的基本方式。

你也可以使用原生的 HTML5.1 dailog。 目前仅 Chrome 37+、Safari 6+ 和 Opera 24+ 支持对话框元素。

var dailog = document.getElementById("dialog"); 

function openModal() { 
   // dailog.show(); 
      dailog.showModal();
} 

function closeModal() { 
    dailog.close(); 
} 
#dialog{width:300px;}
.right{float:right}
<button onclick="openModal()">Show dialog</button>


<dialog id="dialog">This is a dialog window<br/><br/><br/>
<button onclick="closeModal()" class="right">Close</button>
</dialog>

jQueryUI 有一个模态对话框插件。它不会按照您的要求通过单击背景来释放控制权：http://jqueryui.com/demos/dialog/#modal

<a href="#" class="showModal">Show Modal Box</a>
<div id="modalContents" style="display:none;">
  <textarea>Hello World</textarea>
</div>

--

$(".showModal").click(function(e){
  e.preventDefault();
  $("#modalContents").dialog({bgiframe: true, height: 140, modal: true});
});

a 根据定义，模态窗口需要用户执行操作才能返回到主窗口。所以你要找的不是模态而是窗口。

html5 在 chrome 上有 

<dialog>
元素。用它做实验

点击时不会消失的模态弹出窗口：

var popup = document.getElementById("popup");

function openPopup() {
  popup.style.display = "block";
}

function closePopup() {
  popup.style.display = "none";
}
/* Popup container */

.popup {
  display: none;
  /* Hidden by default */
  position: fixed;
  /* Stay in place */
  z-index: 1;
  /* Sit on top */
  left: 0;
  top: 0;
  width: 100%;
  /* Full width */
  height: 100%;
  /* Full height */
  overflow: auto;
  /* Enable scroll if needed */
  background-color: rgba(0, 0, 0, 0.4);
  /* Black background with opacity */
}


/* Popup content */

.popup-content {
  background-color: #fefefe;
  margin: 15% auto;
  /* 15% from the top and centered */
  padding: 20px;
  border: 1px solid #888;
  width: 80%;
  /* Could be more or less, depending on screen size */
}


/* Close button */

.close {
  color: #aaaaaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}
<button onclick="openPopup()">Edit</button>
<div id="popup" class="popup">
  <div class="popup-content"><span class="close" onclick="closePopup()">&times;
</span>
    <form><label for="name">Name:</label><input type="text" id="name" name="name" value="shdhd"><br><br><label for="email">Email:</label><input type="email" id="email" name="email"><br><br><input type="submit" value="Save"></form>
