I am newbie to AngularJS. I have a question, why does ng-change
doesn't passes the $event?
HTML
<div ng-controller="foo">
<select ng-model="item" ng-options="opts as opts.name for opts in sels" ng-change="lstViewChange($event)" ng-click="listViewClick($event)"></select>
</div>
Script
var myApp = angular.module('myApp', []);
angular.element(document).ready(function() {
angular.bootstrap(document, ['myApp']);
});
function foo($scope) {
$scope.sels = [{id: 1, name: 'a'}, {id: 2, name: 'b'}];
$scope.lstViewChange = function($event){
console.log('change', $event); //undefined
}
$scope.listViewClick = function($event){
console.log('click', $event); //object
}
}
Have a look at this fiddle /. Click
passes a valid $event but change
doesn't. Can someone explain this behavior?

Reset to default 5Just to state the obvious, the docs say that ngClick
will pass the event, but ngChange
has no such documentation.
So, what you're asking is why Angular's designers chose to do this? My thought is that ngClick
fires as a result of a click, so it make sense that there would be a mouse event associated with the directive firing. ngChange
on the other hand is a result of any user action that changes the model, which could be associated with all sorts of events rather than one specific event.
