Passing parameters between view only tabular data pages

[BillW]

To Whom It May Concern,

The attached file presents the workflow, defines the setup/scripting, and an  issue encountered when a variable is assigned a value and then passed between two tabular datapages that are set in view only modes.

The solution provided was not the first attempted.  The data source tables for this workflow are linked 1:many, but 'I' was unable to take advantage of that with Tabular datapages.  My second attempt was to simply access the linked data via a button with an associated passed parameter.

Thanks in advance,

BillW

Hello, @BillW.

 

Have you tried using parameters via query string? https://howto.caspio.com/parameters/parameters-as-query-string-values/ 

 

You can look up into the buttons at this link: https://www.w3schools.com/tags/tag_button.asp and try to apply the query string values. I hope this helps.

Hi SinJun,

Thank you for responding.  I have attached an update to the first file.  On the very last page I show that while the coding error appears to be eliminated, the value of the field I wish to assign to a var "ID" is not defined.  The code actually opens the table as requested; however, the parameter is passed as 'undefined', since it is undefined when the var statement is executed.

I wonder if the var is undefined because I have no way to select the specific record that I wish to read the value of CA_ID from?  The reason may be because this tabular table is configured as 'read only'.  I can only highlight a record.

Issue resolved by utilizing caspio's built-in function that uses an HTML block inserted into the child datapage that "links" to the parameter passed from the parent datapage

That is good to know that it's working now, @BillW. Parameters can be a bit complex, but with the right requirements from the DataPage's on load and on exit, this can be achieved. Have a good day!
