Show loading icon while actual image is loading using jQuery

Showing loading for ajax content is pretty common thing but suppose there is a quite big image (in size) on your page and it is taking lots of time to load. Would it not be nice to show loading icon for the same? Well, it creates a nice user experience. The user will come to know that something is loading. So in this post, I will show you how to show loading icon while actual image is loading using jQuery.

Spin plugin to show loading icon with jQuery

 Hi *.*,


Web pages takes time to load and when page is heavy then it takes more time to load. Would it not be nice to show loading icon. It creates responsive webpage and gives nice user experience.In this post, I will show you a plugin to show loading icon.

Features

    No images, no external CSS
    No dependencies (jQuery is supported, but not required)
    Highly configurable
    Resolution independent
    Uses VML as fallback in old IEs
    Uses @keyframe animations, falling back to setTimeout()
    Works in all major browsers, including IE6
    MIT License

How to use it?

var opts = {
  lines: 13, // The number of lines to draw
  length: 7, // The length of each line
  width: 5, // The line thickness
  radius: 21, // The radius of the inner circle
  rotate: 90, // The rotation offset
  color: '#000', // #rgb or #rrggbb
  speed: 2, // Rounds per second
  trail: 93, // Afterglow percentage
  shadow: false, // Whether to render a shadow
  hwaccel: false, // Whether to use hardware acceleration
  className: 'spinner', // The CSS class to assign to the spinner
  zIndex: 2e9, // The z-index (defaults to 2000000000)
  top: 'auto', // Top position relative to parent in px
  left: 'auto' // Left position relative to parent in px
};
var target = document.getElementById('foo');
var spinner = new Spinner(opts).spin(target);

The spin() method creates the necessary HTML elements and starts the animation. If a target element is passed as argument, the spinner is added as first child and horizontally and vertically centered.

Manual positioning

By default the spinner is centered within the target element. Alternatively you may specify a top and left option to position the spinner relative to the target element.

Hiding the spinner

To hide the spinner, invoke the stop() method, which removes the UI elements from the DOM and stops the animation. Stopped spinners may be reused by calling spin() again.

        string[] fileEntries = Directory.GetFiles(imgFolder);

        List<ImageFileInfo> mylist = new List<ImageFileInfo>();

        foreach (string fName in fileEntries)

        {

            string d = System.IO.Path.GetFileName(fName);

            mylist.Add(new ImageFileInfo { FileName = d });

        }

        dtagrid.DataSource = mylist;
