Create message for required fields

[michaelz37588015]

Hello,

I have several fields on a form that are required. Instead of displaying a generic message stating that a required field has been left blank, I would like to display a specific message for each required field, if left blank. Below if what I was trying to start off with but I get a syntax error stating "missing; Before Statement 1: at line 2

Var CoreBankName = this.getField("282_Core_Ref_Bank_Name");
if (CoreBankName !== null)
{
CoreBankName.setFocus()
app.alert("Core Client Bank Name is required")
};

NODIFIED REPLIED , I MADE AN ERROR SEE BELOW AGAIN

If you copy and pasted your code here, it looks like the problem is because the semicolon is outside the instruction line; it should be inside  of the curley braces.

See your line 2 here:

if (CoreBankName !== null)
{
CoreBankName.setFocus()
app.alert("Core Client Bank Name is required")
};

Specifically this part of line 2 : 

 app.alert("Core Client Bank Name is required")
};

It should read like this:

app.alert("Core Client Bank Name is required");
}

Your code is not checking if the field's value is empty, but if the field itself exists.

Also, the required property doesn't check if a field is blank, but if it has a value that's not the same as its default value.

Ok I got lost with your reply a little bit.

Can you re-explain please what does the "if it's null" is implying in the code above?

[try67]

If no field exists with the name parameter you pass to getField it will return null. If it does exist it will return a Field object.

Great. Thank you!

I made the change but still getting the same error. Again, this is a field I have set to be required. I'm trying to check to see if it is null. If it is, then I display a message stating that, that specific field is required. Since I will have about 20 required fields, I want to see if I can get these types of messages more specific to which field needs to be filled in. Below is the code sample where I'm getting the "Syntax Error: missing ; before statement 1: at line 2"

Var CoreBankName = this.getField("282_Core_Ref_Bank_Name");
if (CoreBankName !== null)
{    
   CoreBankName.setFocus()    
   app.alert("Core Client Bank Name is required");
}

I apologize, I am also learning javascripting but I am going to try again.

You also have Var  spelled with the first letter in capital. It should be lower case  "var"

and it's missing  a ".value"  or  ".valueAsString" at the end 

Also, in this line :     if (CoreBankName !== null)

your IF statement is saying if that the obejct field "Is Not Null" it should be expressed if (CoreBankName !=="")

But If you wish to remind the user not to leave that field blank shouldn't it be :

if (CoreBankName=="")     

So I was thinking if your script should read instead something like :

var CoreBankName = this.getField("282_Core_Ref_Bank_Name").valueAsString;

if (CoreBankName=="") app.alert("Core Client Bank Name is required");

and then add your IF/Else statments like shown in line 3 below:

var CoreBankName = this.getField("282_Core_Ref_Bank_Name");

 if (CoreBankName=="") app.alert("Core Client Bank Name is required");

else if(CoreBankName  !=="") event.value = CoreBankName;

I also forgot to ask if it actually matters where are you placing this code.

Is it a custom calculation script ? validation? custom format ? or as a java script that executes on a mouse up or mous on blur option, for example.

[try67]

Use "var", not "Var".

Just to clarify, even if you fix all syntax errors your code still won't work because you're not checking the correct thing, as I wrote before.
