The mobile meta tag

If you have ventured into the world of Mobile web development, you would have realized the importance of the viewport meta tag in the head section of your HTML page. Without the proper meta tag included in your HTML, your web page would zoom, move, be dragged around and basically not client acceptable. To avoid all of this, we need to include a viewport meta tag in the HTML in the head section.

    Jquery mobile suggests the users to use the following viewport meta tag.


<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0">
    By using the above viewport meta tag, the width would be set to pixel width of the device. This would avoid the resizing of the page and there-by the web page would not be draggable any more. However, this would not disable our zooming issue. The user can still zoom the web page by tapping the screen or by pinching it. Jquery mobile suggests that this is a feature that should be included, however, many…

Jquery Mobile - Single Page Structure

We have been introduced to Jquery Mobile and have also seen some of the key features of the rich web framework in the previous posts. Today we will take a look at a general page structure using Jquery Mobile. So be ready to start off programming using Jquery Mobile.

    The Jquery Mobile page structure is optimized to support a single page or local, internally linked multiple pages. What does this mean? Well, single page architecture means, having multiple pages that are linked to each other using the normal process of using the anchor tag. So, each page will have its own header, content and footer. The multiple page structure is basically having multiple pages in one single page within different DIVs. So each page becomes a DIV which is linked to another page using an id for that particular page DIV.
    The multiple page architecture, though available is not popularly used because it results in a performance issue. The DOM becomes heavy as multiple pages load at the same time a…

Jquery Mobile - Touch Optimized, Jquery and HTML5 based web framework

Image
Jquery Mobile - The next level of "Write Less, Do More" mantra of Jquery. Just recently, I started working on a project using the Jquery Mobile framework and just instantly fell in love with it! Jquery Mobile gives immense power and flexibility to developers and enables truly cross-platform and cross-browser and multi-device development. I have just loved it and have decided to share my knowledge with the readers of Spatial Unlimited.



    Jquery Mobile is a touch optimized web framework for smartphones and tablets. It's a unified, HTML5-based user interface system for all popular mobile device platforms, built on the rock-solid jQuery and jQuery UI foundation. Its lightweight code is built with progressive enhancement, and has a flexible, easily themeable design. This is one reason why I love Jquery Mobile. It is easily customizable - no head-ace of themeing; Jquery Mobile does it for you.
    Instead of writing unique apps for each mobile device or OS, the jQuery mo…

Is the data accurate? Can I trust the Rail Radar?" Well, the system is reliable and you can trust the data since the information and intelligence behind the Rail Radar is extracted and harnessed from volumes of data from the official Indian Railway's train running operational data.With regards to accuracy – this is fairly accurate in the normal…
