Facility Control

So.. Kinda hoping there is a really simple sollution to this one that I have yet to grasp...
I am trying to make a table where I want to be able to empty and "reset" the entries when I push a button.

Since the parameters dont really act like arrays (but still kinda do) in javascript, I am somewhat stuck at how to "empthy" the parameters making up the table.
In javascript, emptying an array would be as simple as...

var arr1 = ["a","b","c","d","e"];

arr1 = [];

This would basically empty out the array names "arr1". However I cant find a way to do this in DashBoard?
I hope this is just a case of "fridays" and getting ready for the weekend. Anyone?

I am also looking for how to count the number of rows in the table.

Ok, I did find the "setAllValues" function to basically remove whatever extra I have.
Now I need to get the x-number of rows in said table.
#DashBoard

One thing to note - DashBoard parameters should never be "empty". You'll want to make sure you always have at least one value in any parameter.

We "reset" string arrays with params.setAllValues('OID', ['']);
We "reset" int arrays with params.setAllValues('OID', [0]);

If you want to make a new array that keeps the same number of elements but clears all of the values:

var newValue = [];
for (var i = 0; i < params.getElementCount('OID'); i++)
{
    newValue.push('');
}

params.setAllValues('OID', newValue);

#DashBoard

Yeah... Returning to the documentation got me what I needed.
Both the "setAllValues" and the "getElementCount".

Thanks again though @jamespeltzer !
