var ngEventDirectives = {};
forEach(
   'click dblclick mousedown mouseup mouseover mouseout mousemove mouseenter mouseleave keydown keyup keypress submit focus blur copy cut paste'.split(' '),
   function(name) {
    var directiveName = directiveNormalize('ng-' + name);
    ngEventDirectives[directiveName] = ['$parse', function($parse) {
     return {
      compile: function($element, attr) {
       var fn = $parse(attr[directiveName]);
       return function(scope, element, attr) {
        element.on(lowercase(name), function(event) {
         scope.$apply(function() {
          fn(scope, {$event:event});
         });
        });
       };
      }
     };
    }];
   }
);

在上邊代碼我們可以得到兩個(gè)信息：

①. Angular支持的event： click dblclick mousedown mouseup mouseover mouseout mousemove mouseenter mouseleave keydown keyup keypress submit focus blur copy cut paste

②. Angular在執(zhí)行事件函數(shù)時(shí)候傳入了一個(gè)名叫$event的常量，該常量即代表當(dāng)前event對(duì)象，如果你在Angular之前引入了jQuery那么這就是jQuery的event.

所以我們可以利用event的stopPropagation來(lái)阻止事件的冒泡：如下代碼：jsbin

html 代碼：

<!DOCTYPE html>
<html id="ng-app" ng-app="app">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"></script>
<meta charset="utf-8">
<title>JS Bin</title>
</head>
<body ng-controller="demo as d">
<div ng-click="d.click('parent',$event)">
given some text for click
<hr>
<input type="checkbox" ng-model="d.stopPropagation" />Stop Propagation ?
<hr>
<button type="button" ng-click="d.click('button',$event)">button</button>
</div>
</body>
</html>

js 代碼：

angular.module("app",[])
.controller("demo",[function(){
 var vm = this;
 vm.click = function(name,$event){
  console.log(name +" -----called");
  if(vm.stopPropagation){
   $event.stopPropagation();
  }
 };
 return vm;
}]);

可以在jsbin查看效果。

首先打開(kāi)你的控制臺(tái)，然在沒(méi)選中Stop Propagation的情況下點(diǎn)擊button你將會(huì)看見(jiàn)兩條log記錄，相反選中后則只會(huì)出現(xiàn)button的log信息。

希望本文所述對(duì)大家AngularJS程序設(shè)計(jì)有所幫助。
