该怎么写Angular JS

<html ng-app>

<head>

<title>表单</title>

<script type="text/javascript" src="angular.min.js"></script>

<script type="text/javascript">

function StartUpController($scope) {

$scope.funding = {startingEstimate:0};

computeNeeded = function() {

$scope.funding.needed = $scope.funding.startingEstimate * 10;

};

$scope.$watch('funding.startingEstimate',computeNeeded);//watch监视一个表达式，当这个表达式发生变化时就会调用一个回调函数

$scope.requestFunding = function() {

window.alert("Sorry,please get more customers first.")

};

}

</script>

</head>

<body>

<form ng-submit="requestFunding()" ng-controller="StartUpController"> //ng-submit

Starting: <input ng-change="computeNeeded()" ng-model="funding.startingEstimate">

Recommendation: {{funding.needed}}

<button>Fund my startup!</button>

</form>

</body>

</html>
