Currently using ajax data-table for showing data as frappe data-table is having pagination issue right now. For that i simply created a table in html on form page and within that html code, i used a field for setting field. Now I am trying to put validations between those fields (described above). The websites to which I landed via Google, searching for this query, about every site told me the same but that didn’t worked.
I am using ERPNext v11 and it is currently using ES6 java-script standard so this might be the issue that some syntax or way of doing it might have changed (just a blind guess).
If a search of discuss.erpnext does not give you ideas to your question, a search on ‘datepicker’ ‘validation’ might land you some code to point the way Recent Discussions — DataTables forums
Maybe share your datatable or any validation code for more context?
Syntax errors should show up in web console or server logs, depending on the case.
There is an existing datatype in Frappe called “DateRange” that takes a 2-member list of the start and end dates, and automatically validates them. It’s already being used in a couple of reports.
Not sure about the best way to solve your problem, but you may have fewer headaches with this datatype.
