As mentioned in the jQuery Mobile Docs, jQuery Mobile does not support query parameter passing to internal/embedded pages but there are two plugins that you can add to your project to support this feature. There is a lightweight page params plugin and a more fully featured jQuery Mobile router plugin for use with backbone.js or spine.js.

There are other ways to implement the data passing during different pages but some of them may are not supported from old web browsers. You will have to select your implementation way carefully so that it does not induce consequences to the application's interoperability over multiple browsers.

You can pass data between different pages by using the Web Storage.

As mentioned in the W3schools site, with HTML5 web pages can store data locally within the user's browser. Earlier, this was done with cookies. However, Web Storage is more secure and faster. The data is not included with every server request, but used ONLY when asked for. It is also possible to store large amounts of data, without affecting the website's performance. The data is stored in key/value pairs, and a web page can only access data stored by itself. Web storage is supported in Internet Explorer 8+, Firefox, Opera, Chrome, and Safari. Internet Explorer 7 and earlier versions, do not support web storage.

There are two objects for storing data on the client:

• localStorage which stores data with no expiration date
• sessionStorage which stores data for one session

Examples:

Local Storage Example:

In Page1: localStorage.carType="test";
In Page2 you can retrieve the carType using: localStorage.carType

Session Storage Example:

In Page1: sessionStorage.carNumber=10;
In Page2 you can retrieve the carType using: sessionStorage.carNumber

Regarding your case, a possible solution is to add ids in each anchor. Then catch the click event, retrieve the id, save the id in the web storage and perform the page transition. In the next page retrieve the id from the web storage. Below you can find the implementation:

$('#menu_list').children().each(function(){
    var anchor = $(this).find('a');
    if(anchor)
    {
        anchor.click(function(){
            // save the selected id to the session storage and retrieve it in the next page
            sessionStorage.selectedId=anchor.attr('id');
            // perform the transition
            changePage();
        });
    }
});

EDITED:

Alternative way to pass parameters when following a multiple pages approach

This example uses jQM changePage() to send data with an Ajax page request.

$('#list-d a').on('click', function(e) {
    e.preventDefault();
    $.mobile.changePage('car-details.html', {
        data: {
            id: this.id
        }
    });
});

The constructed URL is .../car-details.html?id=my-id
