What i'm trying to do is use an array or variable to call a particular function. I know that I could use a switch statement to do this, however I would like to find out if it is also possible this way.

PHP Code:

<script>
function test1() {
    alert('test1');
}

function test2() {
    alert('test2');
}

myArray = new Array();
myArray[0] = "test1";
myArray[1] = "test2";

// I really thought this would work, but it didn't
myArray[0]();
</script>

But I don't know if this can work outside of an object.
Try and tell us.

I tried it and couldn't get it to work. great suggestion though.

Ok then, your only solution, as far as I know, i eval():

PHP Code:

<script>
function test1() {
    alert('test1');
}

function test2() {
    alert('test2');
}

myArray = new Array();
myArray[0] = "test1";
myArray[1] = "test2";

// I really thought this would work, but it didn't
eval(myArray[0]+'();');
</script> 


Try to avoid eval if you can.

In Javascript, a function is just another data type. So you can store a reference to the function itself in the array and call it directly:

function test1() {
    alert('test1');
}

function test2() {
    alert('test2');
}

var myArray = [test1, test2];

myArray[0]();
myArray[1]();

The fact that a function is just another type of value might be a little hard to accept if you come from another language like PHP, C etc. But to further illustrate the point, consider this example that redefines test1() after it was already defined:

function test1() {
    alert('test1');
}

function test2() {
    alert('test2');
}

var myArray = [test1, test2];

myArray[0]();
myArray[1]();

test1 = function() {
    alert('Now it\'s something different');
}

myArray[0]();  // Still holds reference to the original test1()
test1();       // but test1() is redefined to a totally new function
