Hello everyone,

Would it be possible for someone to point me in the correct direction regarding a possible script statement.

If a variable I have on screen is between 10 and 40, variable <figure> should show A.

If the onscreen variable is between 41 and 70, variable <figure> should show B.

If the onscreen variable is between 71 and 100, variable <figure> should show C and so on up to possibly 800 for the onscreen variable.

Can this be done in script?

Thank you for looking

The script would be an if then else statement

if (myVariable > 9 && myVariable < 41) DoSomeThing1
else if (myVariable > 40 && myVariable < 71) DoSomeThing2
else if (myVariable > 70 && myVariable < 101) DoSomeThing3

Thank you for your prompt reply.

The operators used in script leave me baffled sometimes. I am picking up scripting as I work but I have unsuccessfully tried to locate a list of script operators and their functions.

This may seem like bread and butter to some guys but it is only easy if you know how !!!

How if somone wants it like this:
if 1,3,5,7....etc I mean odd number it shows A
if 2,4,6,8...etc I mean even number it shows B

Hello Programpal

Yes - can be done

Have attached an Opus example imp for you. Note it is OpusV6.

The script could look something like this;

if (number>=10 && number<=40)
{Image1.Show()
}
if (number>=41 && number<=70)
{Image2.Show()
}
if (number>=71 && number<=100)
{Image3.Show()
}

Note: Imagex is the name of the object that you want to show
Hope this helps

Cheers

taxing the odd gray mater,

if (Math.floor(myNumber/2) == myNumber / 2)
{DoSomethingForEVENNumbers} //Be sure to include the {} braces
else DoSomethingForODDNumbers

Works because when an ODD number is halved, the result always involves a decimal. Therefore, when you compared the rounded (down) result with the result they will not match for ODD numbers, but will match for even.

Thanks Mac for your Great help

Thank you to all for your help. this really is a good forum.
A great product and some good guys on the forum also, what more could you ask for?

I hope that one day I can answer someones query and repay the favour!

You can also use the modulo operator.

if(NUMBER%2==0){
VARIABLE=A;
}
else {
VARIABLE=B;
}


The if checks your number (NUMBER). If it equals 0, it's an EVEN. Otherwise it's an odd. Basically the same as Mac's example, but a little less coding. It's used in HTML often to create alternating row colors for HTML tables.

Hi Brian

Thought I'd play around with your solution and came up with a slightly modified script as follows;

if(number%2==0)
{
tick.Show()
}
else
{
cross.Show()
}


However, when the publication is run, if you return to the Opus editor, you get an alert window that says;

Action (1, 0) : Undefined identifier 'number'

This window does not appear after publishing and running as a stand-alone executable.

Is there someone who can explain the error message to me please? Imp file is attached for experimentation.

Thanks in advance

Graham

I expect it is because "number" is a reserved word in ecmascript - call it "bob", "jim", "graham" or "aardvark" instead...

aardvark it is
Thanks Duncan
You can have the rest of the day off for excellent service!
Enjoy your day
Cheers
Graham

Whoa!

Before you go, aardvark does not work

Get the following message on returning to the editor after testing the publication

Action (1, 0) : Undefined identifier 'aardvark'

The publication works OK but I'm just curious about the error message from a learning perspective.

Don't spend too much time on it Duncan - I've probably done something incorrectly building the sample publication.

You need to unselect the Generate enter on change of focus from the text box

Error message is Gone!

Thanks Mackavi and Duncan

Learned two things

1. Best to avoid using reserved words for variable names

2. Generating enter on change of focus when using scripts can cause an error message.

Cheers
