AngularJS ng-submit 函数未被执行

Question

我正在开发一个 AngularJS 项目，我有一个显示 table 用户的模板，然后有一个按钮（引发模态表单）来添加新的用户。

table 显示正常，模式表单在单击按钮时出现，但绑定到表单的提交功能在单击提交功能时从未触发。这是模板的图像...

用户然后点击 "Add Staff"，这会引发模态...

并且在用户填写表单后，ng-submit 函数永远不会被触发。

这是模板的HTML代码；

这是 Angular 控制器

app.controller("admController", function ($scope, $http, $location) {
        $(document).ready(function() {
            getStaff();
        });

        $scope.addstaffform = function() {
            $scope.formData = {};
                $http({
                    method  : 'POST',
                    url     : 'assets/php/addStaff.php',
                    data    : $.param($scope.formData),  //param method from jQuery
                    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) { //success comes from the return json object

                        $scope.result='bg-success';
                    } else {
                        $('#addModal').modal('hide');
                        getStaff();

                        $scope.result='bg-danger';
                    }
                }).error(function(data){
                    console.log(data);
                });
        };

        function getStaff() {}
            $http.get('assets/php/admin.php')
                    .then(
                        function (response) {
                            $scope.obj = response.data;
                        },
                        function (response) {
                            // error handling routine
                        }
                    );
                });

所以在调试中我发现 $scope.addstaffform = function() 正在加载模板时执行，但在单击提交按钮时它从未触发。

Answer 1

var app = angular.module('myApp', []);
app.controller("admController", function ($scope, $http, $location) {
 $scope.addstaffform = function() {
        alert("hello");
        }

                });

只需更改您的表单名称和函数名称意味着它们应该不同或者它们应该是可区分的 other.This 是我得到的唯一可能的解决方案。

Answer 2

表单名称和函数名称相同是问题所在；

但后来我又发现 ajax 调用的另一个问题 ~ 由于版本 1.6

的变化

旧代码：

$http({
                    method  : 'POST',
                    url     : 'assets/php/addStaff.php',
                    data    : $.param($scope.formData),  //param method from jQuery
                    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) { //success comes from the return json object

                        $scope.result='bg-success';
                    } else {
                        $('#addModal').modal('hide');
                        getStaff();

                        $scope.result='bg-danger';
                    }
                }).error(function(data){
                    console.log(data);
                });

"success" 和 "error" 回调已被弃用，取而代之的是 "then" 和 "catch"。
新代码：

$http({
                    method  : 'POST',
                    url     : 'assets/php/addstaff.php',
                    data    : $.param($scope.formData),  //param method from jQuery
                    headers : { 'Content-Type': 'application/x-www-form-urlencoded' }  //set the headers so angular passing info as form data (not request payload)
                }).then(function (response) {
                    console.log(response.data);
                    ans = response.data;
                    if (!ans.success) { //success comes from the return json object

                        $scope.result='bg-success';
                    } else {
                        $('#addModal').modal('hide');
                        getStaff();

                        $scope.result='bg-danger';
                    }
                }).catch(function(response){
                    console.log(response.data);
                });
