4. Use Case

Consider Zylker, a manufacturing organization. Their service agents use the Orders module of their CRM to create and manage orders for their customers. They have used the latest Canvas Record Form view for their Create Page as shown below.



Below are their requirements.

A. When the checkbox "Is shipping address same as billing address?" is checked, the Shipping Address section should not be visible.
B. When the user clicks the "Add Dental Products" button, a pop-up should appear showing the Dental Instruments available in the Products module, and the instrument details selected in this pop-up should get inserted as rows in the sub-form.

5. Solution

To accomplish the above requirements on the Create Page(Canvas),  you need to create the following two Client Scripts.

A. Client Script with field event on field "Is shipping address same as billing address?"

  • Go to Setup > Developer Space > Client Script. Click +New Script.
  • Specify the details to create a script and click Next.

  • Enter the following script and click Save.
  1. let elem = ZDK.UI.getElementByID('shipping_address');
  2. if (value==true)
  3. {
  4. elem.setVisibility(false);
  5. }

  7. else 
  8. {
  9. elem.setVisibility(true);
  10. }

  • In the above script, "value" will hold the boolean value which hold the user selection of the check box "is-shipping_same_billing". If it is true, then using setVisibility() you can hide the shipping address section. To fetch the ID of the Shipping Address section, you can use ZDK.UI.getElementByID().
  • Here is how the Client Script works.



  • When the user marks "Is shipping address same as billing address" true, you can see that the "Shipping Address" section disappears. 
B. Client Script with button event on canvas button "Add Dental Products"

  • Go to Setup > Developer Space > Client Script. Click +New Script.
  • Specify the details to create a script and click Next.




Enter the following script and click Save.

  1. let products_list = ZDK.Page.getField('Product_List').getValue();
  2. log(products_list);
  3. if (products_list.length === 1) { // Clear subform if empty row
  4.     !Object.values(products_list[0]).every(value => !!value) && products_list.pop();
  5. }
  6. // Open widget with product category & max. allowed rows based on existing subform data
  7. let selected_products = ZDK.Client.openPopup({
  8.     api_name: 'Choose_Products', type: 'widget', header: 'Choose Products', animation_type: 1, height: '570px', width: '1359px', left: '280px'
  9. }, {
  10.     product_category: "Dental Instruments", max_rows: 25 - products_list.length
  11. });

  13. log("products selected from widget: ", selected_products);

  15. // Update Selected Products from the widget Popup 
  16. if (selected_products.length) {
  17.     
  18.     selected_products.forEach(product => {
  19.         products_list.push({ Product_Name1: { id: product.id, name: product.Product_Name }, Quantity_of_Products: 1, Unit_Price1: product.Unit_Price });
  20.     });
  21.     console.log(products_list);
  22.    ZDK.Page.getField('Product_List').setValue(products_list);
  23. }

  • Whenever the button "Add Dental Products" is clicked, you can open a widget as a pop up using ZDK.Client.openPopup(). The details of user selection in the widget will be fetched in the "selected products" variable. You can iterate and create a list to be populated to the Dental Instruments Section. Then this list of values can be populated with the help of setValue().
  • Here is how the Client Script works.



  • When the user clicks the "Add Dental Products" button, a widget of button type that shows the list of Instruments appears. This gets displayed by the Canvas Button event of Create Page (Canvas) and the selected records get inserted in the Dental Instruments subform.
  • Here, using Client Script, you can instantly add all selected products with a single click, eliminating the need to repeatedly click the "+ Add row" button for each product.
