You could do something like, myArray = new Array();

Or

myArray = [];

What are you trying to do? Maybe I can help further.

What values are you trying to add to the array? Are they static values? Are you trying to create a dataSet? Are you grabbing values from the dataSet? Can you please explain your issue in more detail?

If you were wanting to put static values in an array, 1-10, you could do the following:

myArray = [1,2,3,4,5,6,7,8,9,10];

If you put this in your initialize method, you can then recall these values in expressions and script in your report.

myArray[0] would be 1
myArray[1] would be 2
etc...

If you wanted to populate the array with a field in your dataSet, you'd put the following in your initialize:

myArray = [];

Then, to populate it, you'd put something like the following in your onFetch script:

arrayLength = myArray.length;
myArray[arrayLength] = row["myField"];

This would fill your array up with the values in your dataSet field "myField".

Recalling the values would be the same as above.

Does this help? Let me know if you need more infomation.

hi williams, 
Thanks for ur reply ans its working fine. 
Now I want to perform some operations on that Array. 
E.g: for(i=0;i<=5;i++) 
{myArray=i+5} 
how is it possible.

mwilliams

Can you explain more about what operations you want to perform on the array? Your above example would just change the first 5 values in the array to look like:

[5,6,7,8,9]

If that's what you're wanting to do, you already have the script above!
