Executing child-doc code

trainingacademy · November 3, 2025, 8:58am

Hi

I have two parent docs utilizing the same child doc as a table.

Parent_Doc_1 : with table child_doc

Parent_Doc_2 : with table child_doc

I can execute code for the child doc by placing the code in the parent JS-file but then

I would have to put the code in both the JS-file for Parent_Doc_1 and Parent_Doc_2.

I tried putting the code that is executed for the child_doc in the JS-file in the child_doc folder on

the server, but it does not trigger ?

Please if I can ask for some guidance ?

Hi,

You can make common code for this and use this on both doctype.

Example:

github.com/frappe/erpnext

erpnext/public/js/controllers/accounts.js

5b11710a2


      
          				d.row_id = "";
          			}
          		}
          		if (msg) {
          			frappe.validated = false;
          			refresh_field("taxes");
          			frappe.throw(msg);
          		}
          	},
          
          	setup_tax_filters: function (doctype) {
          		let me = this;
          		frappe.ui.form.on(doctype, {
          			account_head: function (frm, cdt, cdn) {
          				let d = locals[cdt][cdn];
          
          				if (d.docstatus == 1) {
          					// Should not trigger any changes on change post submit
          					return;
          				}

erpnext/selling/doctype/sales_order/sales_order.js

          cur_frm.cscript.tax_table = "Sales Taxes and Charges";
          
          erpnext.accounts.taxes.setup_tax_filters("Sales Taxes and Charges");
          erpnext.accounts.taxes.setup_tax_validations("Sales Order");
          erpnext.sales_common.setup_selling_controller();
          
          frappe.ui.form.on("Sales Order", {
          	setup: function (frm) {
          		frm.custom_make_buttons = {
          			"Delivery Note": "Delivery Note",
          			"Pick List": "Pick List",
          			"Sales Invoice": "Sales Invoice",
          			"Material Request": "Material Request",

It is just reference, you can do it something similar to this.
