Using Javascript in LoadRunner scripts

Hi All,

I am using js file in one of my script to encrypt password and a few other parameters. Below is snippet from the code which shows how the request is handled.

Sessionid, token are captured using correlation & password is parameterised.

char *pwd;

char *sessionID;

char *token;

sessionID=lr_eval_string("{correlated_sessionID_param}");

token=lr_eval_string("{correlated_token_param}");

web_js_run(

"code=function('pwd','sessionID','token')",

"ResultParam=param",

SOURCES,

"File=File.js", ENDITEM,

LAST);

The issue is that, instead of the pwd, sessionID, token values, string "pwd", "sessionID", "token" are being passed to the javascript file. 

Please help how I can send the values to js file.

Thanks in advance.

Regards,

Umesh
