Can I have a function name be an array variable?

Question

Can I have a JavaScript loop like this?

SB = new Array;
for (i = 1; i < 6; i++) {
 function SB[i]() {
 (code)
 } // end of function
} // end of for loop

I know that doesn't work but how can I make something like that? Thanks.

Answer 1

Make an anonymous function and return it to the variable.

var SB = [];
for (i=1;i<6;i++) {
 SB[i] = function() {
 //(code)
 }
}

Note that arrays in javascript is 0-indexed.

So you fetch the first item in the array using

myArray[0]

And the last using

myArray[ myArray.length - 1 ]

---

So i think you want to loop with i=0:

var SB = [];
for ( var i = 0; i < 5 ; i++) {
 SB[i] = function() {
 //(code)
 }
}

....

console.log(SB) // [function() {},function() {},function() {},function() {},function() {}]

Instead of:

[undefined, function() {}, function() {}, function() {}, function() {}, function() {}]

Answer 2

var SB=[];
for (i=1;i<6;i++) {
 SB[i] = function () {
 ...
 }
}

You can now invoke it this way:

SB[1]();

Answer 3

Use the bracket notation:

for ( var i = 1; i < 6; i++ ) {
 SB[i] = function() {
 };
}

This attaches a function expression to the array at index i. You are allowed to call it like this:

SB[ 1 ]();
SB[ 2 ]();
// etc..
