Create a Web page named gpa.html that can be used to compute your grade point average given grades and hours for courses completed. The page should repeatedly prompt the user for course information, reading the course name, grade received, and credit hours for a particular course in a single dialog box. The program should continue prompting and reading in grades until the user enters an empty string to signify the end. For example,
Once the course grades have been stored, the page should compute the student's overall GPA. According to the Creighton University Bulletin, grade point averages are computed as follows:
For example, suppose a student entered the following course information (with each line entered in a different dialog box):
The total number of grade points earned by this student is
Dividing this total by the number of credit hours completed yields a GPA of 58/16 = 3.625.
Your page should display the total number of grade points, number or hours, and GPA, as well as all of the course information in a readable form. This information should not be displayed in the page until all user input has been processed. For example,
COURSE GRADE HOURS THL100 B+ 3 PHL107 A 3 ENG120 C+ 3 MTH245 A 4 CSC221 A 3 Total grade points = 58 Number of hours = 16 GPA = 3.625
Hint: For processing the information on each course, you should utilize the string method split, which splits a string into an array of substrings. For example, line.split(/[\s]/) will return an array of substrings of line, using whitespace (\s) as a delimiter.
