This is just playing around and practicing javascript. I am learning JavaScript from Codecademy and I practice coding everyday so I can learn much as possible. I have a lot of if
statements, prompt boxes, some alert boxes. I just got finished learning about functions and returns. I just don't know how to use the return in a browser for like document.write
or even an alert box.
function prompter() {
var toc = prompt("What do you prefer? Tea or Coffee");
if ((toc == "tea") || (toc == "Tea")) {
} else if ((toc == "coffee") || (toc == "Coffee")) {
}
var foc = prompt("What do you prefer? Facebook or MySpace");
if ((foc == "facebook") || (foc == "Facebook")) {
} else if ((foc == "myspace") || (foc == "Myspace")) {
}
document.write("<center><h2>So you like " + toc + " and " + foc + " that is awesome.</h2></center>");
}
function pickAColour() {
var fun = prompt("What is your favorite colour? , mine is red.");
document.write("<center><h2>You like the colour " + fun + " that is a nice colour</h2></center>");
}
function pickANumber() {
alert("Lets do some math, do you like Math?");
var pan = prompt("Please pick a number");
var nap = prompt("Please pick another number");
var symbol = prompt("Please pick one of the following symbols + - * /");
pan = parseInt(pan); //The parseInt() function parses a string and returns an integer.
nap = parseInt(nap); //The parseInt() function parses a string and returns an integer.
if (symbol == "+") {
alert("You picked the Add symbol");
alert("Lets add both these numbers together. " + pan + " " + symbol + " " + nap);
document.write("<center>Your number is " + (pan + nap) + "</center>");
}
if (symbol == "-") {
alert("You picked the Minus symbol");
alert("Lets Minus both of these numbers. " + pan + " " + symbol + " " + nap);
document.write("<center>Your number is " + (pan - nap) + "</center>");
}
if (symbol == "*") {
alert("You picked the Multiply symbol");
alert("Lets Multiply both these numbers. " + pan + " " + symbol + " " + nap);
document.write("<center>Your number is " + (pan * nap) + "</center>");
}
if (symbol == "/") {
alert("You picked the Divide symbol");
alert("Lets Divide both these numbers. " + pan + " " + symbol + " " + nap);
document.write("<center>Your number is " + (pan / nap) + "</center>");
}
}
function run() {
var name = prompt("What is your name?");
document.write("<h1><center>Welcome to this special JavaScript page " + name + "</center></h1>");
prompter();
pickAColour();
pickANumber();
document.write("<center>Thank You for visting this page</center>");
}
run();
