Introduction
 
In this article I am explaining that how can you give splash screen effect to your web application. splash screen effects is just like slideshow or a presentation of your slides. If you are developing the desktop application you can do this very easily but in web application it needs some efforts to do. To make the splash screen effects you have to also add some JavaScript functions to your web application. You can also give animation effects to your web application but here we are discussing splash screen effects.

Getting Started

  • Create a new ASP.NET web application. 
  • Drag a container on page and also set the back color of the page to black. The page will look like below.

  • Then add the below code which contain some JavaScript functions to add splash screen in your web application.

    <html>
                <head>
                            <title>Intro Screen...</title>
                 </head>
    <body bgcolor="#000000" text="#FFFFFF">
    <div id="splashcontainer" style="position:absolute;width:350px;"></div>
    <layer id="splashcontainerns" width="450"></layer>
    <script>
        var preloadimages = new Array("sun.gif", " sun.gif")
        var intervals = 2000
        var targetdestination = "http://www.vbdotnetheaven.com"
        var splashmessage = new Array()
        var openingtags = '<font face="Arial" size="4">'
        splashmessage[0] = '**Welcome to vbdotnetheaven**'
        splashmessage[1] = 'You will find here hell of code, articles and solution of your problems'
        splashmessage[2] = 'All about Microsoft Technology'
        splashmessage[3] = 'Contact us for your web problem solution'
        splashmessage[4] = 'We are always here to provide you the better solution'
        splashmessage[5] = 'Please stand by...'
        var closingtags = '</font>'
        var i = 0
        var ns4 = document.layers ? 1 : 0
        var ie4 = document.all ? 1 : 0
        var ns6 = document.getElementById && !document.all ? 1 : 0
        var theimages = new Array()
        if (document.images) {
            for (p = 0; p < preloadimages.length; p++) {
                theimages[p] = new Image()
                theimages[p].src = preloadimages[p]
            }
        }
        function displaysplash() {
            if (i < splashmessage.length) {
                sc_cross.style.visibility = "hidden"
                sc_cross.innerHTML = '<b><center>' + openingtags + splashmessage[i] + closingtags + '</center></b>'
                sc_cross.style.left = ns6 ? parseInt(window.pageXOffset) + parseInt(window.innerWidth) / 2 - parseInt(sc_cross.style.width)/ 2 :     document.body.scrollLeft + document.body.clientWidth / 2 - parseInt(sc_cross.style.width) / 2
                sc_cross.style.top = ns6 ? parseInt(window.pageYOffset) + parseInt(window.innerHeight) / 2 - sc_cross.offsetHeight / 2 :
                document.body.scrollTop + document.body.clientHeight / 2 - sc_cross.offsetHeight / 2
                sc_cross.style.visibility = "visible"
                i++
            }
            else {
                window.location = targetdestination
                return
            }
            setTimeout("displaysplash()", intervals)
        }
        function displaysplash_ns() {
            if (i < splashmessage.length) {
                sc_ns.visibility = "hide"
                sc_ns.document.write('<b>' + openingtags + splashmessage[i] + closingtags + '</b>')
                sc_ns.document.close()
                sc_ns.left = pageXOffset + window.innerWidth / 2 - sc_ns.document.width / 2
                sc_ns.top = pageYOffset + window.innerHeight / 2 - sc_ns.document.height / 2
                sc_ns.visibility = "show"
                i++
            }
            else {
                window.location = targetdestination
                return
            }
            setTimeout("displaysplash_ns()", intervals)
        }
        function positionsplashcontainer() {
            if (ie4 || ns6) {
                sc_cross = ns6 ? document.getElementById("splashcontainer") : document.all.splashcontainer
                displaysplash()
            }
            else if (ns4) {
                sc_ns = document.splashcontainerns
                sc_ns.visibility = "show"
                displaysplash_ns()
            }
            else
                window.location = targetdestination
        }
        window.onload = positionsplashcontainer
    </script>
    </
    body>
    </
    html>
     
  • Now edit the text which will display in splash screen and the URL which is to be open after the splash screen completes.
     
  • Now run your application.

Output:-
