我是anular.js的初学者。我正在尝试编写一个代码，在按钮单击时添加和删除表中的行，一旦广告用户点击createdelivery按钮，我想将数据作为JSON对象发送到服务器。
但是当我按照以下方式注入$ http时，
var app = angular.module("createDelivery", []);
app.controller("MyController", ['$scope', 'http', function($scope, $http)
它也不会创建表。
请帮我解决这个问题。

var app = angular.module("createDelivery", []);
app.controller("MyController", ['$scope', 'http', function($scope, $http) {
$scope.deliveryDetails = [
{
'fname':'Muhammed',
'lname':'Shanid',
'email':'shanid@shanid.com'
},
{
'fname':'Roy',
'lname':'Mathew',
'email':'roy@roy.com'
}];
$scope.addNew = function(cdDetails){
$scope.deliveryDetails.push({
'fname': "",
'lname': "",
'email': "",
});
};
$scope.remove = function(){
var newDataList=[];
$scope.selectedAll = false;
angular.forEach($scope.deliveryDetails, function(selected){
if(!selected.selected){
newDataList.push(selected);
}
});
$scope.deliveryDetails = newDataList;
};
$scope.checkAll = function () {
if (!$scope.selectedAll) {
$scope.selectedAll = true;
} else {
$scope.selectedAll = false;
}
angular.forEach($scope.deliveryDetails, function(cdDetails) {
cdDetails.selected = $scope.selectedAll;
});
};
$scope.getData = function(cdDetails)
{
alert("Check");
var jsonString;
jsonString = angular.toJson(cdDetails);
//JSON.stringify(jsonString);
$http
({
url: "/scheduler/createDelivery",
dataType: 'json',
method: 'POST',
data: jsonString
}).success(function(response) {
alert("success : : "+jsonString);
$scope.value = response;
}).error(function(error) {
alert("error::"+error);
});
//window.location.reload();
//document.write("\nString value "+jsonString);

代码中的一个错误就是上面。改变它并尝试。你必须注入$ http
