i'm trying sign in pop directly copy-pasted "http://demos.jquerymobile.com/1.4.2/popup/". copied , pasted have go in listed navigation , when click on link nothing happens. url recognizes go .../#popuplogin, there no pop up.

html segment:

<div data-role="page" id="page_home">    <div data-role="navbar" id="navbar">     <div data-role="collapsible" data-collapsed-icon="bars" data-expanded-icon="bars" id="navbar_links">       <h3>menu</h3>       <a href="#popuplogin" data-rel="popup" data-position-to="window" data-transition="pop">sign in</a>       <a href="#page_home" >products</a>       <a href="#page_about">about</a>     </div>   </div>    <div data-role="popup" id="popuplogin" data-theme="a" class="ui-corner-all">     <form>         <div style="padding:10px 20px;">             <h3>please sign in</h3>             <label for="un" class="ui-hidden-accessible">username:</label>             <input name="user" id="un" value="" placeholder="username" data-theme="a" type="text">             <label for="pw" class="ui-hidden-accessible">password:</label>             <input name="pass" id="pw" value="" placeholder="password" data-theme="a" type="password">             <button type="submit" class="ui-btn ui-corner-all ui-shadow ui-btn-b ui-btn-icon-left ui-icon-check">sign in</button>         </div>     </form>   </div> </div> 

you have include right scripts. there quote-mark in mobile.css link make's give 404 , jquery version wrong. links working:

<script src="https://code.jquery.com/jquery-2.1.4.min.js"></script> <script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script> <link href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css" rel="stylesheet"/>
