For submission, you must zip the 2 files into 1 file and upload the zipped file to my website. This assignmen t is meant to get you comfortable with utilizing functions located in a separate function file (as demonstrated in class on Tuesday May 7 th ) Javascript Function file This file will simply contain 2 functions. One called findAvg() which takes in 2 values and returns the average. Another called findMax() which takes in 2 values and returns the maximum. HTML page Create a form for the user to enter 2 integers and a pull down menu wit h the following options listed ... Find Averag e Find Maximum And a button. See my sample output for ass istance on the layout. Once the button is clicked, have your ‘ main ’ javas cript function obtain the i nput including the option chosen in the pull down menu (remember, you mjust set a value for each me nu option so JavaScript can determine which function to use) . If the user selects ‘ Find Averag e ’ , call the findAvg() function from the external file. And so on for the other menu options. Output the result to a <DIV> tag on the webpage. Please note that you must use an external file to hold your functions
