Question

每当我点击我的提交按钮时都没有任何反应，目前我想让它做的就是打印出用户名和密码以测试绑定。我能够与控制器通信并打印出我在控制器中创建的硬编码消息，似乎ng-click不会触发该方法。任何帮助都会很棒，谢谢：D

和控制器类

(function () {
    'use strict';

    angular
        .module('app.register')
        .controller('RegisterController', RegisterController);

    RegisterController.$inject = ['$q', 'dataservice', 'logger'];
    /* @ngInject */
    function RegisterController($q, dataservice, logger) {
        var vm = this;
        vm.message = 'baass';
        vm.userDetails = {
            username: '',
            password: ''
        }

        function activate() {
            var promises = [submitUserDetails()];
            return $q.all(promises).then(function () {
                logger.info('Activated Dashboard View');
            });
        }

        function submitUserDetails() {
            console.log('Username: ' + vm.userDetails.username);
            console.log('Password: ' + vm.userDetails.password);
        }
    }
})();

您需要在控制器上下文中添加b_process.c以使其在视图中可用，因为您只定义了#include <fcntl.h> #include <sys/mman.h> #include <semaphore.h> #include <sys/stat.h> #include <unistd.h> #include <stdlib.h> #include <errno.h> #include <stdio.h> #define SHM_PATH "/instant_messaging" #define SHM_SIZE 50 #define SEM_PATH "/sem_instant_messaging" //dddddddddd char *sendbuff; int main() { //sahred memory setting //shm_unlink(SHM_PATH); int shmfd; shmfd = shm_open(SHM_PATH, O_CREAT | O_RDWR, S_IRWXU | S_IRWXG); if (shmfd < 0) { perror("In shm_open()"); exit(1); } int shm_size = SHM_SIZE; ftruncate(shmfd,shm_size); sendbuff = (char*) mmap(NULL, shm_size, PROT_READ | PROT_WRITE, MAP_SHARED, shmfd, 0); if (sendbuff == NULL) { perror("In mmap()"); exit(1); } //semaphore setting sem_unlink(SEM_PATH); sem_t *sem1; sem1 = sem_open(SEM_PATH, O_CREAT, S_IRUSR | S_IWUSR, 1); while (1) { printf("before wait %d\n", *sem1); int status = sem_wait(sem1); if (status != 0) { perror("in sem_wait"); } printf("after wait %d\n", *sem1); printf("%s", sendbuff); scanf("%s", sendbuff); sem_post(sem1); } }的功能。您应该将其引用绑定到submitUserDetails

submitUserDetails

Answer 2

该函数需要附加到$ scope

$scope.function submitUserDetails() {
        console.log('Username: ' + vm.userDetails.username);
        console.log('Password: ' + vm.userDetails.password);
    }

Answer 3

您的代码似乎存在一些问题，但最大的问题是这些函数实际上并未附加到“this”（vm，因为您已在代码中调用它）。因此，范围无法访问它们，因为它们只能在RegisterController函数内访问。

要解决此问题，我会将此代码添加到您的函数底部：

this.activate = activate;
this.submitUserDetails = submitUserDetails;

同样，submitUserDetails()应该返回一个承诺，不是吗？我希望这也会引起一些时髦的行为。
