    <p>The <code>data-url</code> attribute is used to track the origin of the page element. If it is not explicitly set, the pages embedded within the main application document all have their <code>data-url</code> attribute equal to the page <code>id</code>. The only exception to this is the first-page in the document. When you're requesting a page, then jQuery Mobile firstly tries to locate a page with a matching <code>data-url</code> in DOM. If it does not find a such page then it performs an Ajax request and loads the new page in DOM.</p> <p>You can solve the issue using one of the below 3 ways:</p> <p>Use the below code to remove the second page from DOM when you're moving to another page.</p> <pre><code>$(document).on('pagehide', '#second-page', function(event, ui){ $(event.target).remove(); }); </code></pre> <p>This way when you're moving to the first page, the second page will be removed from DOM and your issue will be solved.</p> <p><strong>OR</strong>:</p> <p>Use:</p> <pre><code>$.mobile.changePage('car-details.html', { data: { id: this.id } }); </code></pre> <p>without using the <code>dataUrl</code> setting.</p> <p>This creates a URL: ../car-details.html?id=my_val</p> <p>On refresh the URL remains the same so you can still get the parameters and the <code>data-url</code> is the same as the page id.</p> <p><strong>OR</strong></p> <p>Before <code>changePage()</code> check whether a page with <code>data-url</code> equal to the second page's id exists in DOM and remove it manually.</p> <pre><code>if ($("#second-page-id").length &gt; 0 &amp;&amp; $("#second-page-id").attr("data-url") === 'second-page-id' ) { console.log('remove from DOM'); $("#second-page-id").remove(); } </code></pre>

    1. COWhen i use the second method specified above, the data-url does not remain same. It becomes same as the page id.

    2. COAlso, i have one more doubt. I have a page with data-URL: /car-details.html?id=my_val. I have the same page with different parameter value for id. If the match is going to be based on data-URL, how is the page getting replaced even if the parameter value is different.

    3. CO@user694688 Yes, using the second solution, the `data-url` is equal to the page id. Why do you need to have different `data-url`?

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.
