在cut事件上指定定制行为。（ctrl+x）时触发-（剪切）时触发
例子：
index.html
<!DOCTYPE html> <html ng-app="bindExample"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body ng-controller="ExampleController"> <input ng-cut="cut=true" ng-model="value"> cut: {{cut}} <script src="framework/angular.js"></script> <script src="js/bbb.js"></script> </body> </html>
script.js
angular.module('bindExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.cut = false;
$scope.value = "cut me";
}]);
