Hello everyone!

Welcome back to another interesting Kaizen post. In this post, we can discuss how to invoke Functions using Client Script and how to handle Timeouts in Client Script. This post will answer the question raised in the post, Why Client Script is not running after function execution?

1. What are Functions in Zoho CRM?

      Functions in Zoho CRM follows the Serverless Computing architecture. It follows cloud computing execution model in which the cloud provider dynamically manages the allocation of machine resources. Zoho CRM provides options for the customer to write their own functions using Deluge script and run their code ( proprietary within Zoho CRM ) without worrying about deploying their code in servers. Click here to know more about Functions.

2. How to Invoke a Function from Client Script?

      You can invoke a function from a Client Script using the  execute() method. Here is the syntax of execute() method. The Client Script execution will only proceed after the Function has completed, demonstrating synchronous behavior.



3. Use Case to use existing function in Client Script

      Zylker, a manufacturing organization, utilizes Zoho CRM. Within their CRM, there is an existing function sendmailToContactRoles that allows meeting invites to be sent to all contact roles associated with a Deal at the click of a button. Deals often require inputs and approval from various stakeholders. By inviting all contact roles, Zylker ensures that all necessary parties are involved in the decision-making process, reducing delays and improving the chances of closing the deal successfully. To avoid accidental clicks, 
  • The admin wants a confirmation message to appear when the Mail icon is clicked, asking for approval and trigger the Function based on user selection. 
  • Additionally, the admin would like to display a success notification , if the emails are sent successfully.
  • Also, once the email is dispatched, a tooltip saying "Invite Sent" should be added should be added to the Mail icon.

4. Solution

  • Create a Client Script to accomplish the above requirements. Click here to know how to create a Client Script.
  • Create a Client Script for "Deals" module with onClick Event and Icon Event Type for the Detail Page(Canvas).

  • Enter the following code and click Save.
  1. var isProceed = ZDK.Client.showConfirmation('Do you want to invite the Contacts of the Deals', 'Proceed', 'Cancel');
  2. var elem = ZDK.UI.getElementByID('icon');
  3. //If user clicks Proceed button
  4. var deal_rec = $Page.record_id;
  5. if (isProceed) {
  6.  ZDK.Apps.CRM.Functions.execute("sendmailToContactRoles", deal_rec);
  7.  ZDK.Client.showMessage(" All the Contacts have been invited successfully");

  9.  elem.addToolTip({ text: 'Invite Sent' });
  10. }
  11. else {
  12.  elem.addToolTip({ text: 'Click to send invite' });
  13. }

  • After getting user's confirmation with showConfirmation() , the execute() method triggers the function. 
  • The parameters of execute() are function name and parameters. 
  • The name of the existing function is "sendmailToContactRoles". 
  • The parameters of the function are record ID of the Deal and subject of the email.
  • $Page is a constant supported by Client Script, using which you can get information about the current record. 
  • $Page.record_id will give the id of the current record.
  • Once the function gets executed successfully, you can display the success message using showMessage() . To know more about displaying messages using Client Script , check our Kaizen post Creating Alerts and messages using Client Script.
  • Here is how the Client Script works.

  • Here is the Function code where emailSubject and deal ID are the arguments of this function.
  1. relatedcontrole = zoho.crm.getRelatedRecords("Contact_Roles","Deals",input.dealId.toLong());
  2. emailSubject="Meeting Invite";
  3. emailContent = " Click the following link to join the meeting this evening at 5.00 pm" + " https://meeting.zoho.com/meeting/presenter.do?key=1069852805&cid=5668066&x-meeting-org=53296550";
  4. salutation = "<p>Hello!!<br /><br /></p>";
  5. signature = "<br /><br /><p>Best Regards,<br />Patricia Boyle</p>";
  6. sub = input.emailSubject.toString();
  7. str = input.emailContent.toString();
  8. str = concat(salutation,str);
  9. str = concat(str,signature);
  10. for each role in relatedcontroles
  11. {
  12. emailAddress = role.get("Email");
  13. info emailAddress;
  14. sendmail
  15. [
  16. from :zoho.adminuserid
  17. to :emailAddress
  18. subject :sub
  19. message :str
  20. content type :HTML
  21. ]
  22. }

  • You can achieve the functionality of sending emails in Functions using Client Script itself using fetchRelatedRecords() and  openMailer(). Here, we have made use of the existing Function. 
You can use Functions in Client Script,

To leverage existing Functions for similar functionality, thereby enhancing reusability and to trigger Functions based on UI events such as Icon Event, onType Field Event, Canvas Text Event, and others, beyond the buttons and workflows already supported by Functions.

5. Timeouts in Client Script 

In Client Script, executions are bounded by a 10-second time out. During execution of API calls or during the execution of a function which involves API calls , it might take more than 10 seconds to provide response. Consequently, when they are used in Client Script, execution will get halted. To overcome such scenarios you need to use Loaders.

6. How to handle timeouts in a Client Script?

Client Script allows you to manage the timeout by using a loader. The execution of Client Script will be on hold, as long as the loader is active, and so the timeout will not occur.

a. showLoader()

Use showLoader() to display the loader.



b. hideLoader()

Use hideLoader() to make the loader inactive.



7. Timeout Scenario :

At Zylker, which uses Zoho CRM, there is an existing function named "Books_send_quote" in their Zoho CRM account. The admin wants this function to execute via a Client Script whenever the status is updated to delivered and display a message saying, "Quote has been sent successfully." The admin added the script to show a success message after the function execution. 

Problem :

During execution of the following code, the admin noticed that the code following the function invocation is not running. Similar problem is described in this post.

The current code is 

  1. if (value == Delivered) {
  2. ZDK.Apps.CRM.Functions.execute("Send_Quote");
  3. ZDK.Client.showMessage('Quotation sent successfully', { type: 'success' });
  4. }

In such scenarios, the Messages Pane of Client Script IDE will show Timeout as shown below.



Solution:

 Since the timeout limit of 10 seconds has reached, further execution did not occur. So you need to add ZDK.Client.showLoader() before the execution of the Function and ZDK.Client.hideLoader() after the function execution.

  1. if (value == 'Delivered') {
  2. ZDK.Client.showLoader({type:'page', template:'spinner', message:'Sending Quotation...' });
  3. ZDK.Apps.CRM.Functions.execute("Send_Quote");
  4. ZDK.Client.hideLoader();
  5. ZDK.Client.showMessage('Quotation sent successfully', { type: 'success' });
  6. }
Here is how the Client Script works.



The presence of loader on the screen will inform the user about the ongoing processes in the background.
