How to convert String to a Function?

Admirer

Hi,

I am new for this Tool, I am trying to build a framework for my application. Could you please guide me...

Excel file having following details:

KeywordAction PropertyNames Values
set xxxx Help
setPwd xxxx xxxxxx
clickButton Submit
...

In the above details, "KeywordAction" column having UserDefined Functions.

i am able to retrieve the functions, however i am facing a problem i.e.

$fName = $rs[$i]["KeywordAction"]
$fName($rs[$i]["PropertyNames"], $rs[$i]["Values"]);

Here it's shown error message as "JSERROR TypeError: $cm is not a function, it is string."

But in QTP, I can do this as follows:

fname = datatable.value("KeywordAction","SheetName")
propName = datatable.value("PropertyNames","SheetName")
vals = datatable.value("Values","SheetName")

execute fname propName, vals

if I write like this, QTP will identify "fname" as function and run.

Is there any Functiion/Method in SAHI?


Thanks in Advance.

Thanks & Regards,
Tulasi.

Hi Tulasi,

Use eval(string) to convert it into a function (or whatever that string represents).

In your case, it would be

$fName = $rs[$i]["KeywordAction"];
var $fn = eval($fName); // converts to function.
$fn($rs[$i]["PropertyNames"], $rs[$i]["Values"]);
