EASY array question (I would think...)

[JoeDunford]

I am trying to perform a simple calculation and put the results into each field of an array of numeric fields.  I am using Javascript in LifeCycle 8.

e.g. #1

var Total;

Total = 23;

nf[0].rawValue = Total;

nf[1].rawValue = Total + 1;

THIS DOESN'T WORK ????  I also tried the following

e.g.

var Total;

Total = 23;

nf.rawValue = Total;

nf.index = 1;

nf.rawValue = Total + 1;

This also doesn't work. please help me add values to specific items within the numeric field array, this is driving me nuts.....

One thing that should help is to turn on the debugger in adobe reader in the preview pane.  You can do this by right-clicking anywhere, click Page Display Properties, then click Javascript, and check off the console window.

From how you have things here you haven't defined nf as a variable.  The console should error back stating that nf is undefined.  If you create the array variable first it should work fine.  Should look something like this:

var number = [];

number[0] = 2;
number[1] = 3;

var total = number[0] + number[1];
equals.rawValue = total;

This works as array variables.  If you are trying to use field names, you need to change it slightly.  The correct formatting to specifiy and instance of a field would be:

fieldname[1].rawValue = whatever variable or value

The problem here is that this syntax in Livecycle for specifying the instance of that field conflicts with the syntax for javascripting, the '[]' makes livecycle think that you are dealing with an array.  So in order to get you need to use the structure:

xfa.resolveNode("fieldname[1]").rawValue

This then uses a function to resolves the node name and avoids trying to take the [] brackets literally.

Hope this helps, I had the same trouble.  Just gotta get used to the syntax.
