Default If X, Y & X are Blank, then do this, else do that.

We are trying to create a rule that basically says

If Field “X” and Field “Y” and Field “Z” are empty
return Resourse “Blank”
else
return Resource “YellowLine”

We have tried this several ways and are not able to make it work. Here are 3 of the different ways we tried to write it… HELP!!!


if(Field ("Name") != "" || Field("Phone") != "" || Field("Email") != "") return NullResource(<none>);
else
return Resource("YellowLine");



if (Field("Name") == "")
if (Field("Phone") == "")
if (Field("Email") == "")
return Resource("Blank");
else
return Resource("YellowLine");



if (Field("Name") == ""&&Field("Phone") == ""&&Field("Email") == "");
return Resource("Blank");
else
return Resource("YellowLine");

Hello Diane,

Try this one...
Code:
if ((Field("Name") == "") && (Field("Email") == "") && (Field("Phone") == ""))  {
    return Resource("Blank");
}
else  {
    return Resource("YellowLine");
}
I think you were a bit mixed up with the use of parenthesis.

Diane, I just wanted to note that your previous efforts weren't that far off. Here's why they didn't work, though:
Code:
if(Field ("Name") != "" || Field("Phone") != "" || Field("Email") != "") return NullResource(<none>);
else 
return Resource("YellowLine");
If you remove the "<none>" tag in the "NullResource" function, the above code will work perfectly.
Code:
if (Field("Name") == "")
if (Field("Phone") == "")
if (Field("Email") == "")
return Resource("Blank");
else
return Resource("YellowLine");
There's actually nothing wrong with the above code but it's important to note that the way it's written is actually interpreted as a nested if statement. Like this:
Code:
if (Field("Name") == "") {
    if (Field("Phone") == "") {
        if (Field("Email") == "") {
            return Resource("Blank");
        }
    }
}
else {
    return Resource("YellowLine");
}
Code:
if (Field("Name") == ""&&Field("Phone") == ""&&Field("Email") == "");
return Resource("Blank");
else
return Resource("YellowLine");
If you were to remove the semi-colon at the end of the if condition, the above code would work as well. The semi-colon is used to separate statements in JavaScript so that particular semi-colon is interrupting the if statement.

Yet another way to write this is using the ternary operator:
Code:
return (Field("Name") || Field("Phone") || Field("Email")) ? Resource("YellowLine") : Resource("Blank");

You can also get rid of the "else" in those rules. If you return, then you immediately leave the rule and don't ever run any of the code past that return statement.

I am a not a Support engineer, and this forum is not a substitute for Support. My participation on this forum is primarily as a fellow user (and a forum moderator). I am happy to provide help and answers to questions when I can; however, there is no guarantee that I, or anyone else on this forum, will be able to answer all questions or fix any problems. If I ask for files to clarify an issue, I might not be able to look at them personally. I am not able to answer private messages, emails, or phone calls unless they go through proper Support channels. Please direct any sales or pricing questions to your salesperson or inquiries@marcom.com.

Complex template-building questions, as well as all installation and font questions or problems, should be directed to FusionProSupport@marcom.com. Paid consulting work may be required to fulfill your template-building needs.

Please include the specific versions of FusionPro, Acrobat, and your operating system in any problem reports or help requests. I recommend putting this information in your forum signature. Please also check your composition log (.msg) file for relevant error or warning messages.

How To Ask Questions The Smart Way

The correct spellings are JavaScript, FusionPro, and MarcomCentral (each with two capital letters and no spaces). Acceptable abbreviations are JS, FP, and MC (or MCC). There is no "S" at the end of "Expression" or "Printable"! The name of the product is FusionPro, not "Fusion". "Java" is not is not the same as JavaScript.

Check out the JavaScript Guide and JavaScript Reference! FusionPro 8.0 and newer use JavaScript 1.7. Older versions use JavaScript 1.5.

return "KbwbTdsjqu!spdlt\"".replace(/./g,function(w){return String.fromCharCode(w.charCodeAt()-1)});
