Traditionally, web forms are configured to submit synchronously. When users submit a form, they are redirected to an acknowledgement page, or in case of submission failure, an error page. However, modern web experiences like single page applications are gaining popularity where the web page remains static while client-server interaction happens in the background. You can now provide this experience with adaptive forms by configuring asynchronous submission. In this case, an adaptive form behaves like a single page application as the form does not reload or its URL does not change when the submitted form data is validated on the server.
Read on for details about asynchronous submission in adaptive forms.
-
In the On Submit section, select one of the following options to perform on successful form submission.
- Redirect to URL: Redirects to the specified URL or page on form submission. You can specify a URL or browse to choose the path to a page in the Redirect URL/Path field.
- Show Message: Displays a message on form submission. You can write a message in the text field below the Show Message option. The text field support rich text formatting.

When a form is submitted, the data is transmitted to the server for validation, which returns a response to the client with information about the success or error event for the submission. The information is passed as parameters to the relevant handler to execute the function.
In addition, form authors and developers can write rules at form level to override default handlers. For more information, see Override default handlers using rules.
Let us first review the server response for success and error events.
{
contentType : "<xmlschema or jsonschema>",
data : "<dataXML or dataJson>" ,
thankYouOption : <page/message>,
thankYouContent : "<thank you page url/thank you message>"
}
The server response in case of successful form submission includes:
- Form data format type: XML or JSON
- Form data in XML or JSON format
- Selected option to redirect to a page or display a message as configured in the form
- Page URL or message content as configured in the form
The success handler reads the server response and accordingly redirects to the configured page URL or displays a message.
{
errorCausedBy : "<CAPTCHA_VALIDATION or SERVER_SIDE_VALIDATION>",
errors : [
{ "somExpression" : "<SOM Expression>",
"errorMessage" : "<Error Message>"
},
...
]
}
The server response in case of error in form submission includes:
- Reason for the error, failed CAPTCHA or server-side validation
- List of error objects, which includes the SOM expression of the field that failed validation and the corresponding error message
The errors handler reads the server response and accordingly displays the error message on the form.
Form developers and authors can write rules, at form level, in code editor to override default handlers. The server response for success and error events is exposed at form level, which developers can access using $event.data in rules.
Perform the following steps to write rules in code editor to handle success and error events.
