Simple Array Help

Read this tutorial: http://w3schools.com/js/js_obj_array.asp

Thanks for the quick reply try67,

However, I've already read through w3 before. Love the site, very useful. And I know what arrays are, but I just can't figure out how to do the run through of 1-10. or 1-12, or whatever it is.

I can do the simple name arrays, but how do you run through a range? Like counting in excel would. Thanks for your help.. =/

For that you can use a for-loop, like so:

var myArray = new Array("Saab","Volvo","BMW");
for (i=0; i < myArray.length; i++) {
console.println(myArray[i]);
}

Or you can use the for-in-loop, like so:

var myArray = new Array("Saab","Volvo","BMW");
for (i in myArray) {
console.println(myArray[i]);
}

Now I have this, but I don't understand what's wrong with it?

var myArray = new Array("01","02","03","04","05","06","07","08","09","10","11","12");
for (i=0; i < myArray.length; i++) {
console.println(myArray[i]);

event.value = getField("myArray").value;
if ((event.value == 0) && (getField("Cost 1999").valueAsString === "")) event.value = "";In other words, I'm lost. console.printIn isn't what I'm lookin for is it..? I'll keep digging..

Hey try67, thanks for your help. I just stuck with the non-array. I know it's sloppy but I won't know the difference at work.

Thanks!

My example was supposed to demonstrate how to access an item in the array, using the array's name followed by the index in square brackets. console.println just prints the names of the items in the array to the console.

As it is now, you're trying to access a field called "myArray" in this line:
event.value = getField("myArray").value;

What you want to do is the following:

// define the array
var myArray = new Array("01","02","03","04","05","06","07","08","09","10","11","12");

// initialise the value
event.value = 0;

// loop over the array and add all of the values of the fields defined in it
for (i=0; i < myArray.length; i++) {
event.value += this.getField(myArray[i]).value;
}

// if the total value is 0 and field "Cost 1999" is empty, reset the final value
if ((event.value == 0) && (this.getField("Cost 1999").valueAsString === "")) event.value = ""
