Form - Events & Methods

Events

Form behavior can be customized with the help of the call-back events. These events can be accessed from the events tab on the Properties panel. The trigger for the event can be JavaScript, another Variable call etc..

Event	Trigger and JavaScript Usage
On before submit	This event will be called before submitting the form. Any validation checks can be performed here. Returning false from the script will stop the form submit.

We are assuming that Notification Action notificationAction1 is already created.

Page.form1Beforesubmit = function ($event, widget, $data) {
    //$data has the data of the all widgets inside the form. This data can be modified and validated before sending the request

    //Validation can be performed here. If validation fails, return false will stop the operation and service call will not be made
    if (data.password.length < 6) {
        Page.Actions.notificationAction1.invoke({
            "class": "error",
            "message": "Password too small",
            "position": "center center"
    });;
        return false;
    //Data can be modified before making a service call
    $data.dateModified = Date.now(); //Set today's date as modified date field
};

Event	Trigger and JavaScript Usage
On submit	This event will be called on submitting the form. (This is called after ‘on before submit’. If on before submit returns false, this function will not be called).

Page.form1Submit = function ($event, widget, $formdata) { 
//$formData has the data of the all widgets inside the form.
console.log(“Form data:”, $formdata);
};

Event	Trigger and JavaScript Usage
On result	This event will be called after the form is submitted and API returns a response. This event is triggered in both success and failure cases.

Page.form1Result = function ($event, widget, $data) { 
//$data has the response returned from the API.
console.log(“server response:”, $data);
};

Event	Trigger and JavaScript Usage
On success	This event will be called after the form is submitted and API returns a success response.

Page.form1Success = function ($event, widget, $data) { 
//$data has the response returned from the API.
console.log(“The inserted data:”, $data);
};

Event	Trigger and JavaScript Usage
On error	This event will be called after the form is submitted and API returns a failure response.

Page.form1Error = function ($event, widget, $data) { 
//$data has the error message returned from the API.
console.log(“Error returned from server:”, $data);
};

Methods

Form has few methods exposed on widget scope.

To submit form:

Page.Widgets.[formName].submit();
//This method submits the form. 
//This method can be used if form is to be submitted from outside of the form.

To clear messages from the form:

Page.Widgets.[formName].clearMessage();
//This method removes the success/error message on the form.
