Kiddergarden guessing game page
You will be provided with a function named
checkEndGame()
that displays an alert
box telling the user whether he or she has won the game by guessing the number within
the allotted number of guesses, or has lost by failing to guess the correct number. The rest
of the code is left for you to complete.
Complete the following:
1. Use your text editor to open the
guesstxt.htm
file from the tutorial.11\case3 folder
included with your Data Files. Enter
your name
and
the date
in the comment section
of the file and save it as
guess.htm
. Take some time to study the content and structure
of the document, including the elements within the
guessform
web form.
2. Within the
script
element, declare the following four global variables:
lowest
,
size
,
randNum
, and
guess
. The
lowest
variable will be used to store the low-
est possible random integer in the guessing game. The
size
variable will store the
number of random integers in the game. The
randNum
variable will store the random
number generated by the Web page. The
guess
variable will store the user's current
guess. Set the initial values of the
lowest
and
size
variables to
1
and
500
, respec-
tively. Do not set initial values for the
randNum
and
guess
variables.
3. Below the four variable declarations you just created, insert the
generateRandom()
function. The function, which will be used to generate a random number, has no
parameters. It should contain a single statement to set the value of the
randNum
vari-
able to a random integer between the values of the
lowest
and
size
variables. (Hint:
Use the code describing how to generate random integers presented in the tutorial to
aid you in writing this function.)
