Question
"Programming in JavaScript assignment"
Note: To assist you in the completion of this assignment please review Chapter 2 (in order to figure out how to incorporate JavaScript in HTML) and Chapter 2 and 7 (to figure out how to access elements).
Create a web page that has 2 text boxes that users can enter their weight in pounds and the other to enter height in inches and a button with an onclick event that calls a function called calcBMI which performs the BMI calculation.
The expression for BMI is: Weight*703/(height*height)
Type and save your work in a document and upload to the assignment drop-box. You do not need to include a cover sheet, but you do need to put your name, date, assignment number and instructor's name at the top of the page.
