Hi @jonathangilbert ,
To hide the Submit button until a Multirow Variable Set (MRVS) has at least one entry, you need to use a Catalog Client Script that checks the MRVS row count and toggles the visibility of the Submit button accordingly.
Step-by-Step Solution:
- Use a Catalog Client Script (Type: onLoad and onChange)
Create a Catalog Client Script on the catalog item with the following configuration:
- Type: onLoad and onChange
- Applies to: The MRVS variable
- Script:
function toggleSubmitButton() {
var rowCount = g_form.getValue('your_mrvs_variable').split(',').filter(Boolean).length;
g_form.setSubmitButtonVisible(rowCount > 0);
}
toggleSubmitButton();
- Replace 'your_mrvs_variable' with the actual name of your MRVS variable.
2. Handle Dynamic Updates with onChange
To ensure the Submit button updates when rows are added or removed, create an additional onChange Catalog Client Script on the MRVS variable:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading) return;
toggleSubmitButton();
}
This ensures the visibility of the Submit button updates dynamically as users interact with the MRVS.
Best Practices:
- Avoid DOM manipulation: Use g_form.setSubmitButtonVisible() instead of hiding buttons via document.getElementById() or jQuery.
- Use split(',') cautiously: This assumes the MRVS stores row IDs as a comma-separated string. If your setup differs, you may need to use Glide APIs or a GlideAjax call to count rows.
- Consider mandatory fields inside MRVS: If you want to ensure valid entries, you may need to validate required fields within each row before enabling Submit.
