正常是双向绑定如下
<!DOCTYPE html>
<html ng-app="myapp">
<head>
    <meta charset="utf-8">
    <title>ng-model directive</title>
</head>
<body ng-controller="HelloController">
<script src="angular.min.js"></script>
<script>
	var app=angular.module("myapp",[]);
    app.controller("HelloController",function($rootScope,$scope) {
    	$scope.greeting="haoning";
    
        $scope.consoleng = function() {
            console.log($scope.greeting) ;
        }
        
    });
</script>

<div>
    <p>bbbbbbbbb</p>
    <input id="thism" ng-model="greeting" >
    <p>Hello {{greeting || "World"}}</p>
    <button ng-click="consoleng()" >dayin</button>
    <button ng-click="cha()">cha</button>
    <hr>
</div>
</body>
</html>

$scope.greeting与ng-model="greeting"
绑定,党model变了,打印的scope的greeting也变了


然而如果引入了ng-include 的子页面
在子页面改了model之后,scope中的数据没有如期改变

需要处罚apply方法使数据改变,apply又存在安全问题,
解决办法如下

外层的为
out.html
<!DOCTYPE html>
<html ng-app="myapp">
<head>

    <meta charset="utf-8">
    <title>ng-model directive</title>
</head>
<body ng-controller="HelloController">

 
<script src="angular.min.js"></script>
<script>
	var app=angular.module("myapp",[]);
    app.controller("HelloController",function($rootScope,$scope) {
    	$scope.safeApply = function(fn) {
		    var phase = this.$root.$$phase;
		    if (phase == '$apply' || phase == '$digest') {
		        if (fn && (typeof(fn) === 'function')) {
		            fn();
		        }
		    } else {
		        this.$apply(fn);
		    }
		};
    	$scope.greeting="haoning";
    
        $scope.consoleng = function() {
            console.log($scope.greeting) ;
        }
        $rootScope.cha = function() {
        	console.log("cha");
           	$scope.safeApply(function () {  
           		$scope.greeting = document.getElementById("thism").value;  
        	});
        }
    });
</script>

<div ng-include="'inner.html'" 
            class="sidebar sidebar-right"></div>
</body>
</html>

内层的为
inner.html
<div>
    <p>bbbbbbbbb</p>
    <input id="thism" ng-model="greeting" >
    <p>Hello {{greeting || "World"}}</p>
    <button ng-click="consoleng()" >dayin</button>
    <button ng-click="cha()">cha</button>
    <hr>
</div>


使model的值改变后,手动触发一下apple那个方法,
才能改变scope中的值
分析,
加了
	$scope.safeApply = function(fn) {
		    var phase = this.$root.$$phase;
		    if (phase == '$apply' || phase == '$digest') {
		        if (fn && (typeof(fn) === 'function')) {
		            fn();
		        }
		    } else {
		        this.$apply(fn);
		    }
		};


$rootScope.cha = function() {
        	console.log("cha");
           	$scope.safeApply(function () {  
           		$scope.greeting = document.getElementById("thism").value;  
        	});
        }
