Lab10bxx.html — Easy Grade Calculator
Before you start, be certain that you have watched the Forms Textboxes and Buttons video, the two arithmetic videos Writing a Function With Parameters – Add and Arithmetic without forms and the 3 minute Math.round video and the two if statements videos, Introduction to the If Statement, and Using the If Statement. These videos are short ~ 3-19 minutes and will help you with the assignment.
Part I — Easy_Calc.html - Save your assignment in your All_102Submissions folder. The user will enter the eight grades and the program will write the average of the grades in a text box.
Create a page that has eight text boxes for entering quiz grades.
Include appropriate headings to the left of the text boxes.
And one more text box for the quiz average.
Include an h2 below the text box that holds the average that says That's My quiz average? .
Crate a button that when clicked
calls a function that:
calculates the rounded average
Round the average using the JavaScript function Math.round.
writes the rounded average into the 9th text box.
And if the average is greater than or equal to 90
replace the text in the h2 that says That's My quiz average? with text that says I got the A!
Give the h2 an id and use an assignment statement – innerHTML.
And turn the background color of the page to red.
Carefully test your code and make sure it is correct.
Part II— Grade_Calc.html – Design a calculator that has text boxes to enter grades:
For the user to enter:
Test1 grade

HW grade
The program writes to:
A text box for your final grade
A text box for your letter grade
