Frappe Framework Custom Script
1

Hello to all expert here. Kindly give some help to some beginners like me here in ERPNEXT.

Here is the situation. I want to create a function where I want to get the code value set on the Text Field (T_FIELD) and set it automatically on Hidden Field (H_FIELD) set also and register it. How can I do this? Below is the parameters:

DocType: TestForm
Text Field: T_FIELD
Text Field Value: 000: Apple, 001: Banana (Pull Down Menu)
Hidden Field: H_FIELD

Actual target result:
When “001: Banana” is set on the Text Field (pull down menu), “001” code must be set on Hidden Field.

have he hidden field read only also, and on h_field option put doc.t_field it should work.

Thanks for your reply. I appreciate it very much. But I only need not the whole value but only the code (ex: 001).

T_FIELD is a Link field?

T_FIELD is the field name of the text box where the data will be input.

So u write 001:Banana by hand or u select it from the drop down in T_FIELD? If u are using a Link Field (drop down menu), the link will help

write a “custom script”… and use split function in javascript and set the value of hidden value…
