Question

In javascript: Let the user input multiple integers/variables. then return them in order and least to greatest.

Is there any similar way alike to using infile/outfile from java in javascript?

Answer 1

If you have your numbers in an array you can use the .sort(function(a,b){return a-b});

like

var myArray = [10, 7, 4, 9, 0]

myArray.sort(function(a,b){return a-b});

will return the array [0, 4, 7, 9, 10]

Answer 2

If you're sorting integers just use the .sort() method and it will sort them alphabetically

Answer 3

Also, if you only use the .sort() method on integers, it will sort them by their first digit

var myArray = [1, 2, 11, 112, 23, 43]

myArray.sort()

would return the array with [1, 11, 112, 2, 23, 43]

Answer 4

omg !

Answer 5

wait, how do i get the user to input multiple numbers using an array?

Answer 6

var hi1 = new Array ()
will that work?

Answer 7

It should, yes.

You could just write var hi1 = [ ];
and then write a loop that takes user input and use the .push() method to push the user input into an array

Answer 8

this is so not what i have learned from chp.7 and 8. i don't know why my teacher keeps on giving me hw that has nothing to do with what i have learned-.....-

Answer 9

var multi1 = [];
var multi1 = window.prompt( "Enter any variables as you wish." );

do i connect the prompt like this? how do prompt the user to store the integers into
multi1?

Answer 10

got that part.
var multi1 = [];
multi1 = window.prompt( "Enter any variables as you wish." );

Answer 11

um, do you think itd b possible for you to briefly tell me about .push() method :( !?

Answer 12

if you had
var multi1 = [1,2];
multi1.push(3);

It would push the value 3 into the array multi1

Answer 13

but the user is inputting many integers into the array multi1
how can i store all the integers and return it to the user?

Answer 14

Do you know how many?

Answer 15

i think it can be any... but preferably alot lol !

Answer 16

if you set it up
var multi1 = [ ];
wouldnt it intake multiple variables/integers????

Answer 17

If you typed them there

Answer 18

var multi1 = [];
multi1 = window.prompt( "Enter any variables as you wish." );


so this would prompt the user to enter variables into multi1
and the array mutli1 would store multiple variables correct?

Answer 19

But it would only run once. One sec I'm writing an example program

Answer 20

It only takes numbers? Or does it take strings too?

Answer 21

is it easier to take only numbers?
but doesn't it take string values first, then dont i have to convert it into integers?

Answer 22

Yes if one inputted a number it would by "3" not the number 3 so it would be easier to take only numbers

Answer 23

it's string "3" right?
i just store string variables. then return to the user the "inputted string values" right?

Answer 24

You could

Answer 25

and if i document.writeln( multi1 );
would it return all of the inputted string values?

Answer 26

It should, yes

Answer 27

it does not work :' (

Answer 28

it stored 1 value!

Answer 29

is there a way for me to store it one by one by letting the user press enter?

Answer 30

var h1 = [];
var bool = true;

while(bool === true){
var input = prompt("Enter anything you like");
h1.push(input);
var end = prompt("Are you done? y/n");
if(end === "y"){
bool = false;
}else{
continue;
}
}

console.log(h1);

Answer 31

I have to head out now, but I'll be on later. That should be what you're looking for. Just tweak it until it's right

Answer 32

THANK YU!

Answer 33
