How to limit the length of input field

[Former Member]

Hi,

In my adobe form there is one ISR Multiple line edit input element. If the user enters less than 2 characters, the system should

throw error saying that the length is less than 2. I guess some java scripting is needed for this.

Please help.

Thanks,

Hi Madhu,

Thanks a lot, it worked but any idea how to give message on the top of the page(not in a popup box).

Himanshu,

You can try out two things, see it it serves your purpose.

1. Place a ISR_TextDisplay element on top of form. Keep it invisible in by writing following code in form:ready event of subform

ISR_TextDisplay.presence = "invisible"

and and then write the code in Exit event .

var a = $.rawValue
var s = len(a)
if ( s < 2 )
then
ISR_TextDisplay.presence = "visible"
ISR_TextDisplay.rawValue = "Length is less than 2"
endif

2. Alternatively for the ISRMultipleLineEdit element goto the Object palette --> Value tab --> Change the type as User Entered Required. This will a red border if user has forgotten to enter any data in that field.

Hi

Place the below script in Exit Event of your field with Script selected as Formcalc

var a = $.rawValue

var s = len(a)

if ( s < 2 )

then

$host.messageBox("Length is less than 2")

endif

Thanks & Regards,

Madhu.

Hi Himanshu,

you may need to use form calc here for coding.

On the input field 'validate' event use the following method on the input value to check the length

Len(s) where s is the string to be examined

then you can show a message to user saying the length is less
