SEMESTER VII

WEB PROGRAMMING LABORATORY

Subject Code: 10CSL78 I.A. Marks: 25

Hours/Week : 03 Exam Hours: 03

Total Hours : 42 Exam Marks: 50

1. Develop and demonstrate a XHTML file that includes JavaScript script for the

following problems:

a) Input: A number n obtained using prompt

Output: The first n Fibonacci numbers

b) Input: A number n obtained using prompt

Output: A table of numbers from 1 to n and their squares using alert.

2. a) Develop and demonstrate, using JavaScript script, a XHTML

document that collects the USN ( the valid format is: A digit from 1 to 4

followed by two upper-case characters followed by two digits followed by

two upper-case characters followed by three digits; no embedded spaces

allowed) of the user. Event handler must be included for the form element

that collects this information to validate the input. Messages in the alert

windows must be produced when errors are detected.

b) Modify the above program to get the current semester also (restricted to be

a number from 1 to 8).

3. a) Develop and demonstrate, using JavaScript script, a XHTML

document that contains three short paragraphs of text, stacked on top of each other, with only enough of each showing so that the mouse cursor can be placed over some part of them. When the cursor is placed over the exposed part of any paragraph, it should rise to the top to become completely visible.

b) Modify the above document so that when a paragraph is moved from the top stacking position, it returns to its original position rather than to the bottom.

4. a) Design an XML document to store information about a student in an engineering college affiliated to VTU. The information must include 100 USN, Name, Name of the College, Brach, Year of Joining, and e- mail id.Make up sample data for 3 students. Create a CSS style sheet and use it to display the document.

b) Create an XSLT style sheet for one student element of the above document and use it to create a display of that element.

5. a) Write a Perl program to display various Server Information like Server

Name, Server Software, Server protocol, CGI Revision etc.

b) Write a Perl program to accept UNIX command from a HTML for and to

display the output of the command executed.



6. a) Write a Perl program to accept the User Name and display a greeting

message randomly chosen from a list of 4 greeting messages.

b) Write a Perl program to keep track of the number of visitors visiting the

web page and to display this count of visitors, with proper headings.

7. Write a Perl program to display a digital clock which displays the current time

of the server.

8. Write a Perl program to insert name and age information entered by the user

into a table created using MySQL and to display the current contents of this

table.

9. Write a PHP program to store current date-time in a COOKIE and

display the ‘Last visited on’ date-time on the web page upon reopening of the

same page.

10. Write a PHP program to store page views count in SESSION, to

increment the count on each refresh, and to show the count on web page.

11. Create a XHTML form with Name, Address Line 1, Address Line 2, and E-

mail text fields. On submitting, store the values in MySQL table. Retrieve

and display the data based on Name.

12. Build a Rails application to accept book information viz. Accession

number, title, authors, edition and publisher from a web page and store the

information in a database and to search for a book with the title specified

by the user and to display the search results with proper headings.



Lab Instructions

Steps to Execute XHTML Program.

1. Create a folder by your name in any directory

2. Open notepad and type the program and save the file with .html extension in your

folder.

3. Then open the Internet Explorer /Mozilla web browser and type

the URL as directoryname:\foldername\filename.html

Ex: E:\cse\data.html

4. Finally output will display.

Steps to Execute XML using XSLT & CSS Program

1. Create a folder by your name in any directory

2. Open notepad and type the XML program and save the file with .xml extension in your

folder.

3. Open notepad and type the XSL/CSS program and save the file with .xsl extension for

XSLT

program & save the file with .css extension for CSS program in your folder.

4. Then open the Internet Explorer /Mozilla web browser and type

the URL as directoryname:\foldername\filename.xml

Ex: E:\cse\pgmname.xml

5. Finally output will display.

Steps to run perl and Php programs #su #password: server

# cd /var/www/cgi-bin

# vi program_name.pl

All perl programs should be saved under .pl extension vi 6a.pl

save and Quit

#chmod 777 6a.pl //change the file permission before execution

To see the output go to browser and in the address bar type http://localhost/cgi-bin/6a.pl

http://localhost/cgi-bin/6a.pl



Steps to run MYSQL programs [root@localhost ~]# service httpd start

Starting httpd:

[root@localhost ~]# service mysqld start

Starting MySQL: [ OK ]

[root@localhost ~]# mysql

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 5 to server version: 3.23.58

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
