我刚开始使用AngularJS
。但是,为什么这不起作用?
加载网页后,我进入Uncaught ReferenceError: $scope is not defined
行81
的{{1}} $scope.processForm = function() {
帮忙?
// define angular module/app
var formApp = angular.module('formApp', []);
// create angular controller and pass in $scope and $http
function formController($scope, $http) {
// create a blank object to hold our form information
// $scope will allow this to pass between controller and view
$scope.formData = {};
// process the form
$scope.processForm = function() {};
}
// process the form
$scope.processForm = function() {
$http({
method: 'POST',
url: 'process.php',
data: $.param($scope.formData), // pass in data as strings
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
} // set the headers so angular passing info as form data (not request payload)
})
.success(function(data) {
console.log(data);
if (!data.success) {
// if not successful, bind errors to error variables
$scope.errorName = data.errors.name;
$scope.errorSuperhero = data.errors.superheroAlias;
} else {
// if successful, bind success message to message
$scope.message = data.message;
}
});
};

答案 0 :(得分:8)
将控制器内的空$scope.processForm
(function formController($scope, $http)
)替换为当前外部的$scope
。
在控制器内部,它可以访问您注入的{{1}}。
