The reference documentation notes the following:
updateOn: a string that specifies which event should be bound to the input. Multiple events can be set using a space delimited list. There is also a special 'default' event that aligns with the default events of the control.
The documentation lists a few events such as blur, default, and submit. Are there any additional events not mentioned here? Is there a comprehensive list available somewhere?
It is possible to assign any DOM event to the updateOn property. For a comprehensive list, you can refer to this page.
Examining the Source code of ngModel, reveals that the chosen options for updateOn will be linked directly to the element itself.
View Angular Source here: https://github.com/angular/angular.js/blob/master/src/ng/directive/ngModel.js#L1188
Snippet from Angular Source:
if (modelCtrl.$options.getOption('updateOn')) {
element.on(modelCtrl.$options.getOption('updateOn'), function(ev) {
modelCtrl.$$debounceViewValueCommit(ev && ev.type);
});
}
In the latest Angular update, a new feature allows for controlling the value or validity of a form (or single form elements) when they are updated. While this capability existed in AngularJS 1.x, it was missing from Angular 2+ until now. Here are the update options available for Angular 5 forms:
change: This is the default mode where the form/form control is updated after each individual change.
blur: The blur change mode updates the form values/validity status only after a form control loses focus.
submit: Updates occur only after the form is submitted.
You can find more information about this update here.
