我有这个例子jquery弹出代码:http://jsfiddle.net/9jrrd1hL/

<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<body>
<div data-role="page">
  <div data-role="header">
    <h1>Welcome To My Homepage</h1>
  </div>
  <div data-role="main" class="ui-content">
    <a href="#myPopupDialog" data-rel="popup" data-position-to="window" data-transition="fade" class="ui-btn ui-corner-all ui-shadow ui-btn-inline">Open Dialog Popup</a>
            <p>Table Example:</p>
<style type="text/css">
table.example5 {background-color:GreenYellow;border:1px dotted black;width:100%;}
table.example5 th, table.example5 td {text-align:center;border:0;padding:5px;background-color:transparent;}
table.example5 th {background-color:LimeGreen;color:white;}
table.example5 th:first-child {width:20%;}
</style>
<table class="example5">
<tr>
<th rowspan="2">Table header</th><td>Table cell 1
</tr>
<tr>
<td>Table cell 2</td>
</tr>
</table>
      <p>Frames Example:</p>
<iframe src="/html/templates/frames/frames_example_1.html" width="80%" height="90%">
</iframe>
    <p>Image  Example:</p>
<a href="http://www.quackit.com/travel/new_zealand/milford_sound"><img src="/pix/milford_sound/milford_sound_t.jpg" style="max-width:100%" alt="Milford Sound in New Zealand" /></a>
    <p>Frames Example:</p>
<iframe src="/html/templates/frames/frames_example_1.html" width="80%" height="90%">
</iframe>
    <p>Image  Example:</p>
<a href="http://www.quackit.com/travel/new_zealand/milford_sound"><img src="/pix/milford_sound/milford_sound_t.jpg" style="max-width:100%" alt="Milford Sound in New Zealand" /></a>

    <div data-role="popup" id="myPopupDialog">
      <div data-role="header">
        <h1>Header Text</h1>
      </div>
      <div data-role="main" class="ui-content">
        <h2>Welcome to my Popup Dialog!</h2>
        <p>jQuery Mobile is FUN!</p>
        <a href="#" class="ui-btn ui-corner-all ui-shadow ui-btn-inline ui-btn-b ui-icon-back ui-btn-icon-left" data-rel="back">Go Back</a>
      </div>

      <div data-role="footer">
        <h1>Footer Text</h1>
      </div>
    </div>
  </div>
  <div data-role="footer">
    <h1>Footer Text</h1>
  </div>
</div>

我有一个大的背景在我的实际代码，所以，我想做的是，每次弹出窗口打开，我想要它避免用户能够滚动向下或向上基于背景。

使用这个打开弹出按钮

<a href="#myPopupDialog" data-rel="popup" data-position-to="window" data-transition="fade" class="ui-btn ui-corner-all ui-shadow ui-btn-inline" onclick="document.body.style.overflowY = 'hidden'">>Open Dialog Popup</a>

和你的goback按钮

<a href="#" class="ui-btn ui-corner-all ui-shadow ui-btn-inline ui-btn-b ui-icon-back ui-btn-icon-left" data-rel="back" onclick="document.body.style.overflowY = 'visible'">Go Back</a>

您还可以为您的容器div添加id，并将按钮上的onclick功能更改为onclick="document.getElementById("containerID").style.overflow = 'hidden'";和onclick="document.getElementById("containerID").style.overflow = 'visible'";

可以将body溢出设置为隐藏，如下所示:

$(body).css("overflow", "hidden");

，只要使用:

$(body).css("overflow", "auto");

希望能有所帮助。
