    <p>I have this code and I want in javascript to extract the username and password to make some sort of login verification. How can I do that? Edit: I am using a node js server to extract some data, but is has nothing to do with the login page I want to do. I am trying to make a login and when the user presses the button to login it ill verify if the password and username matches (login verif) and if it foes it goes to the menu if it doesnt, gives an error. </p> <pre><code>&lt;div id="login" data-role="page"&gt; &lt;div data-role="panel" id="mypanel" data-theme="a" data-position="left" data-display="reveal"&gt; &lt;ul data-role="listview" data-theme="h"&gt; &lt;li&gt; &lt;a href="#menu" &gt; Menu&lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="#register" &gt;Register&lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="#cart" &gt; Cart&lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="#account" &gt; Account&lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="#login" &gt; Login&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/div&gt;&lt;!-- /panel --&gt; &lt;div data-role="header" data-theme="a" data-position="fixed"&gt; &lt;a href="#mypanel" data-role="button" data-icon="bars" data-iconpos="notext" data-corners="false"&gt;&lt;/a&gt; &lt;h1&gt;Log In&lt;/h1&gt; &lt;/div&gt; &lt;div data-role="content"&gt; &lt;!-- username --&gt; &lt;label for="username"&gt;Username&lt;/label&gt; &lt;input id="username" title="Must be at least 8 characters."/&gt; &lt;br /&gt; &lt;!-- password --&gt; &lt;label for="password"&gt;Password&lt;/label&gt; &lt;input id="password" type="password" title="title it hard to guess." /&gt; &lt;br /&gt; &lt;p&gt; &lt;button type="button" title="This button won't do anything"&gt; Proceed &lt;/button&gt; &lt;/p&gt; &lt;label for="register"&gt;Don't have an account?&lt;/label&gt; &lt;/div&gt; &lt;div data-role="content"&gt; &lt;a href="#register"&gt;Register&lt;/a&gt; &lt;/div&gt; &lt;/div&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
