IF
statement (Javascript form):
For using conditions like the IF we need to modify the
javascript form of the code and add new code to the existing javascript. While
this makes the script more powerful, one cannot return to the old regular
MonkeyTalk script form. In order to export the script click on the javascript
tab at the bottom of the editor window in MonkeyTalk IDE and then click on
Export button at the top.
We will illustrate the use of If statement by using two
scripts, driver and driven. The driver script will pass the username and
password to the driven script twice (two iterations). In one of the iteration
the password is invalid and therefore the page will throw error. The driven
script verifies if that error exists and then executes certain part of the code
else it executes some other part of the code.

= function(user, pass) {
this.app.input("username").enterText(user);
this.app.input("password").enterText(pass);
this.app.button("LOGIN").tap();
var a =
this.app.label("login_err").get("a");
/*
* The get() function returns a string
which
* is displayed on the label having id as
"login_err"
* This element is always displayed on the
screen.
* When the login page throws no error the
string is void
* i.e. it is equal to ""
* This returned string is stored in
variable 'a'
*/
if(a
== "Sorry! Password must be 4 or more characters.")
/*
* The
if statement, tests if the string captured in a
* is
equal to the same error message.
*
* If
value returned is TRUE then
* new
set of username and passwords are entered followed
* by
user clicking the "forms" tab and then the "login" tab
*
* If
value returned is FALSE then the user is logged in
* and
all we need to do is logut the user. Followed by
* user
clicking the "hierarchy" tab and then the "login" tab

{
this.app.input("username").tap();
this.app.input("username").enterText("new
username");
this.app.input("password").enterText("new
password");
this.app.button("LOGIN").tap();
this.app.button("LOGOUT").tap({thinktime:"3000"});
this.app.tabBar().select("forms",
{thinktime:"3000"});
this.app.tabBar().select("login",
{thinktime:"3000"});
}

{
this.app.button("LOGOUT").tap({thinktime:"3000"});

Variable declaration:-
Variables can be initialized at the time of declaration:
Vars * Define usr=john pw=smith
Input username EnterText ${usr}
Input password EnterText ${pw}
The above script will enter john as username and smith as
password.
However, if the above script is being driven by a driver
script (as mentioned in example 2), which passes arguments then the values
provided as arguments in the driver script trump the ones defined in the above
script. Example:
Script driven.mt Run albert einstein
Also, mentioned in example 2 is that if a driver script only
passes one argument then it is replaces the values stored in the first declared
variable and the second one remains as it is.
Script driven.mt Run albert
