output form/field value using variables as form/field names

Hi all

Im having trouble retreiving the value of fields contained within forms inside a tabform.

I have a loop giving me an array of form names within a tabform, then a nested loop which gives me the fields on each given form.

My problem is this

I can get the field value by using the complete form field naming

application.output(forms.filter_criteria_comp_det.com_det_ad_analysis_code.valueOf())

also I can get the same result with

application.output(forms[form_name].com_det_ad_analysis_code.valueOf())

where [form_name] is a variable contaning an item from an array of form names

however I cannot get a value when trying to use a variable as a field name from an array of fields

application.output(forms[form_name].[form_field].valueOf())

I dont know if im using the wrong notation, but the valueOf() statements throws an error each time i attempt this

Could someone advise me on the correct syntax for this

Regards

Hi McCourt,

Zuke:
application.output(forms[form_name].[form_field].valueOf())

I dont know if im using the wrong notation, but the valueOf() statements throws an error each time i attempt this

You are using a period too many:
application.output(forms[form_name].[form_field].valueOf())

should be

application.output(forms[form_name][form_field].valueOf())

Hi

Thanks for the feedback

However im still getting the same error without the extra period

application.output(forms[form_name][form_field].valueOf())

TypeError: Cannot call method “valueOf” of undefined

Hi McCourt,

Can you check what the values are when you get the error?

Hi ROCLASI

You are completely correct,

It turns out my error was related to my arrays

My form array index starts at 1
However i had incorrectly began my field array index at 0 which obviously meant the valueOf() was referencing an empty array element.

Having began my field array at 1 instead of zero i now get the desired form field values.

Many thanks for the input
