为何个人AngularJs代码没生效？

• 字母拼写错误

<script type="text/javascript">
var app = angular.model("myApp", []);//此处应为module
app.controller("myCtrl", function($scope){
	//code……
});
</script>

• 漏写参数

<script type="text/javascript">
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope){
	$scope.myUrl = $location.absUrl();//$location漏放到function($scope, $location){}中
});
</script>

• 本地程序http涉及跨域，不容许访问，页面没有效果

<script type="text/javascript">
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope, $http){
	$http.get("http.html").then(function (response) {
		$scope.myWelcome = response.data;
	});
});
