Step 4: Let us see the script code which you have to add inside the <script></script> tags and that will be placed either in the < Head> section or the <Body> section as you prefer.

<script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script>

Step 6: In this step we have to write the jQuery code which is given below.

<script type="text/javascript">
        //Secify scroller contents
        var line = new Array()
        line[1] = " Hi friends I m Akshay.."
        line[2] = " I discover an awsome script "
        line[3] = "It brings up the text acording to your requirment..."
        line[4] = "One letter at a time"
        line[5] = "You can add subtract lines "
        line[6] = "It\'s very cool and new one to use"
        line[7] = "For more about jQuery follow http://www.c-sharpcorner.com"
        var ts_fontsize = "17px"
        //--Don't edit below this line
        var longestmessage = 1
        for (i = 2; i < line.length; i++) {
            if (line[i].length > line[longestmessage].length)
                longestmessage = i
        }
        var tscroller_width = line[longestmessage].length
        lines = line.length - 1 //--Number of lines
        //if IE 4+ or NS6
        if (document.all || document.getElementById) {
            document.write('<form name="bannerform">')
            document.write('<input type="text" name="banner" size="' + tscroller_width + '"')
            document.write('</form>')
        }
        temp = ""
        nextchar = -1;
        nextline = 1;
        cursor = "\\"
        function animate() {
            if (temp == line[nextline] & temp.length == line[nextline].length & nextline != lines) {
                nextline++;
                nextchar = -1;
                document.bannerform.banner.value = temp;
                temp = "";
                setTimeout("nextstep()", 1000)
            }
            else if (nextline == lines & temp == line[nextline] & temp.length == line[nextline].length) {
                nextline = 1;
                nextchar = -1;
                document.bannerform.banner.value = temp;
                temp = "";
                setTimeout("nextstep()", 1000)
            }
            else {
                nextstep()
            }
        }
        function nextstep() {
            if (cursor == "\\") {
                cursor = "|"
            }
            else if (cursor == "|") {
                cursor = "/"
            }
            else if (cursor == "/") {
                cursor = "-"
            }
            else if (cursor == "-") {
                cursor = "\\"
            }
            nextchar++;
            temp += line[nextline].charAt(nextchar);
            document.bannerform.banner.value = temp + cursor
            setTimeout("animate()", 25)
        }
        //if IE 4+ or NS6
        if (document.all || document.getElementById)
            window.onload = animate
</
script
>

Step 7: In this step we will see the complete code of the Default2.aspx page which is given below.

Code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title> Advanced Typing Scroller Using JQuery</title>
    <script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script
>
<script type="text/javascript">
        //Secify scroller contents
        var line = new Array()
        line[1] = " Hi friends I m Akshay.."
        line[2] = " I discover an awsome script "
        line[3] = "It brings up the text acording to your requirment..."
        line[4] = "One letter at a time"
        line[5] = "You can add subtract lines "
        line[6] = "It\'s very cool and new one to use"
        line[7] = "For more about jQuery follow http://www.c-sharpcorner.com "
        var ts_fontsize = "17px"
        //--Don't edit below this line
        var longestmessage = 1
        for (i = 2; i < line.length; i++) {
            if (line[i].length > line[longestmessage].length)
                longestmessage = i
        }
        var tscroller_width = line[longestmessage].length
        lines = line.length - 1 //--Number of lines
        //if IE 4+ or NS6
        if (document.all || document.getElementById) {
            document.write('<form name="bannerform">')
            document.write('<input type="text" name="banner" size="' + tscroller_width + '"')
            document.write('</form>')
        }
        temp = ""
        nextchar = -1;
        nextline = 1;
        cursor = "\\"
        function animate() {
            if (temp == line[nextline] & temp.length == line[nextline].length & nextline != lines) {
                nextline++;
                nextchar = -1;
                document.bannerform.banner.value = temp;
                temp = "";
                setTimeout("nextstep()", 1000)
            }
            else if (nextline == lines & temp == line[nextline] & temp.length == line[nextline].length) {
                nextline = 1;
                nextchar = -1;
                document.bannerform.banner.value = temp;
                temp = "";
                setTimeout("nextstep()", 1000)
            }
            else {
                nextstep()
            }
        }
        function nextstep() {
            if (cursor == "\\") {
                cursor = "|"
            }
            else if (cursor == "|") {
                cursor = "/"
            }
            else if (cursor == "/") {
                cursor = "-"
            }
            else if (cursor == "-") {
                cursor = "\\"
            }
            nextchar++;
            temp += line[nextline].charAt(nextchar);
            document.bannerform.banner.value = temp + cursor
            setTimeout("animate()", 25)
        }
        //if IE 4+ or NS6
        if (document.all || document.getElementById)
            window.onload = animate
</
script
>
</html>
