Preventing form submission when there is no attachment

[Muhammad 1]

@lhieanne 

Could you ensure that you pass the sys_id in the script include, and use == (double equals) instead of === (triple equals)? This is because it === checks both value and type and if the response type differs, it will throw an error. Additionally, kindly share the script include code.

here is the include

var AttachmentRequiredHelper = Class.create();

AttachmentRequiredHelper.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getAttachmentRequired: function() {

        var appDisplayName = this.getParameter('appSysId'); // Get the Display Name passed from the client script

        // Log the Display Name for debugging purposes

        gs.info('Display Name received by Script Include: ' + appDisplayName);  // This will log the Display Name

        // Query the u_adt_application_support table for the provided Display Name

        var gr = new GlideRecord('u_adt_application_support');

        gr.addEncodedQuery('u_adt_active=true^u_application=' + appDisplayName);

        gr.query();

        // Check if a record is found and return the attachmentRequired value

        if (gr.next()) {

            var attachmentRequired = gr.u_attachment_required.toString(); // Convert Boolean to string

            // Log the attachmentRequired value for debugging

            gs.info('Attachment Required for application ' + appDisplayName + ': ' + attachmentRequired);

            return attachmentRequired;

        }

        // Log when no records are found

        gs.info('No record found for Display Name: ' + appDisplayName);

        // Return 'false' if no records are found

        return 'false';

    },

    hasAttachments: function() {

        var tableSysId = this.getParameter('tableSysId');

        var attachment = new GlideRecord('sys_attachment');

        attachment.addQuery('table_sys_id', tableSysId);

        attachment.query();

        return attachment.hasNext().toString();  // Return 'true' if attachments are found, otherwise 'false'

    },

    type: 'AttachmentRequiredHelper'

});

try this code : 

function onSubmit() {

    var appSysId = g_form.getValue('adt_application_name'); 

 

    if (!appSysId) {

        g_form.addErrorMessage('Application Sys ID is required.');

        return false;  // Prevent form submission if apprised is empty

    }

    alert("Application Sys ID: " + appSysId);

    var ga = new GlideAjax('global.AttachmentRequiredHelper');

    ga.addParam('sysparm_name', 'getAttachmentRequired');

    ga.addParam('appSysId', appSysId);

    ga.getXMLAnswer(handleAttachmentRequiredResponse);

    // Always prevent form submission initially

    return false;

    // This function handles the attachment-required response

    function handleAttachmentRequiredResponse(response) {

        try {

            if (!response) {

                alert('Error: No response from GlideAjax');

                return;

            }

            var attachmentRequired = response;

            alert("Attachment Required Response: " + attachmentRequired);

            if (attachmentRequired === 'true') {

                alert('Attachment is required, checking for attachments...');

                checkAttachments(g_form.getUniqueValue());  // Check for attachments if required

            } else {

                alert('Attachment is not required, submitting form...');

                g_form.submit();  // Submit form if no attachment is required

            }

        } catch (e) {

            alert('Error in handling the GlideAjax response: ' + e.message);

        }

    }

    // This function checks for attachments

    function checkAttachments(tableSysId) {

        var attachmentGa = new GlideAjax('global.AttachmentRequiredHelper');

        attachmentGa.addParam('sysparm_name', 'hasAttachments');

        attachmentGa.addParam('tableSysId', tableSysId);

        attachmentGa.getXMLAnswer(handleAttachmentsResponse);

    }

    // This function handles the response to check for attachments

    function handleAttachmentsResponse(response) {

        try {

            if (!response) {

                alert('Error: No response from GlideAjax');

                return;

            }

            var hasAttachments = response;

            alert("Has Attachments Response: " + hasAttachments);

            if (hasAttachments === 'false') {

                alert('No attachments found, preventing form submission...');

                g_form.addErrorMessage('Attachment is required because "Attachment Required" is set to True for the selected app.');

                return false;  // Prevent form submission if there are no attachments

            } else {

                alert('Attachments found, submitting form...');

                g_form.submit();  // Submit the form if attachments are found

            }

        } catch (e) {

            alert('Error in handling the GlideAjax response: ' + e.message);

        }

    }

}

Does this even work?

function onSubmit() {

    return false:

}

If not, maybe start debugging on the client in Dev tools.
