AngularJS Event Handlers

AngularJS Event Handlers: Events directives signal the application to respond to changes in the environment. Some of the changes may be user-initiated, others may be automated program functions. The following directives can be placed in your HTML to listen for events that your application can respond to.

  • ng-blur
  • ng-change
  • ng-click
  • ng-copy
  • ng-cut
  • ng-dblclick
  • ng-focus
  • ng-keydown
  • ng-keypress
  • ng-keyup
  • ng-mousedown
  • ng-mouseenter
  • ng-mouseleave
  • ng-mousemove
  • ng-mouseover
  • ng-mouseup
  • ng-paste

The event directives enable you to call AngularJS functions at specific user events. If you have both an Angular event and an HTML event, both events will take place.

Mouse Events

A Mouse Event happens when the user moves a cursor over ng-mouseleave HTML element:

  • ng-mouseenter
  • ng-mousemove
  • ng-mouseleave
  • ng-mouseover
  • ng-mouseup

Or when the button is clicked on an element

  • ng-mousedown
  • ng-mouseup
  • ng-click

Mouse events can be added to any element on the web page. We, Will, examine the ng-click directive.
