Is there a way to create a dynamic array of integers on Javascript?
Let me explain a little further. I am designing a number generator that allows the user to input 9-13 numbers, select 3 "places" in that array, and input another number to fill those spots, so that the original number is altered in the output.
Example: The user enters 123-12-1234 The user selects the [0], [1], [2] The user inputs 5 Result: the output is 555-12-1234
Code is appreciated.
Something like the following should get you started
var arrayOfInts = [];
var input = ""; // accept user input in some way (text input in page?)
arrayOfInts.push(parseInt(input, 10));
// Now work with arrayOfInts
There's functions to the Javascript 'Array' object. On http://www.w3schools.com/jsref/jsref_obj_array.asp, you can find all functions and properties. Some examples:
var list = new Array(123,475,142,89);
Adding/deleting an element to/from the array:
list.push(286);
// Added integer '286'
var num = list.pop();
// Returns the last element and deletes it from the array
var index = list.indexOf(475);
// Returns the position of element '475' in the array, if present
