Unable to set a global variable - sahi

Question

I want to use a function and the parameter I am passing should be set to global all the time. How can I do that? Here is my code:
function ReadExcelfunction($FileName,$SheetName,$RowNum,$ColNum,$Parameter)
{
var $excel = _getExcel($FileName,$SheetName);
var $excelData=$excel.getData();
var $Parameter=$excelData[$RowNum][$ColNum];
//_setGlobal($Parameter,$excelData[$RowNum][$ColNum]) -- Commented
}
Now suppose I pass the parameters as -- File sheet 1 1 Name.
What I want is this: name with the Value is stored as Global value.
Earlier I used _setGlobal($Parameter,$excelData[$RowNum][$ColNum]) which solved the purpose but this API has been removed and now I need to change my script.
I am using the sahi scripting language which is similar to JavaScript.

Answer 1

You don't need to use _setGlobal, you only need to declare a var before the function declaration. For example, you can declare a new Array and then set/get values just like _setGlobal.
// www.google.com used as start URL
var $globalVariable = new Array();
function SetGlobalVariable(key, newValue) {
$globalVariable[key] = newValue;
}
SetGlobalVariable('inputValue', 'stack overflow');
_setValue(_textbox("q"), $globalVariable['inputValue']);

Answer 2

A probable solution for you is to write value to an existing excel sheet cell from the sahi script on the fly and then retrieve the same value from the corresponding cell of excel sheet from another sahi script.
I have done a similar thing using a simple text file.
First File
\\ script 1
var $str = "Hello World";
var$filePath = "C:\\temp\\mystring.txt";
_writeToFile($str, $filePath);
Second File
\\ script 2
var $filePath = "C:\\temp\\mystring.txt";
var $mystr = _readFile($filePath);

Create a Sahi Function to creating a new excel sheet:
function _createExcelFile($fileName, $sheetName){
if($sheetName == null || $sheetName == ""){
$sheetName = "Sheet1";
}
_debug("Excel File Name :: " + $fileName);
_debug("Excel File Sheet Name :: " + $sheetName);
var $excelPoi = new Packages.net.sf.sahi.util.ExcelPOI($fileName, $sheetName);
$excelPoi.createNew();
}
Further you can refer the _getExcel($filePath[, $sheetName]) API from Sahi Pro. You need to do some iterations to get things done. You can read and write data as required.
Note: I have tried this only in the latest version of Sahi Pro i.e. 6.1.0.
