Question

所以我正在开发我的第一个MEAN堆栈应用程序，我正在使用类型脚本。

我的帖子工作得很好，但我的编辑帖子不起作用。由于这是我的第一个应用程序，我不太清楚为什么。该错误表明我的帖子的参数未定义。我希望你们中的一个可爱的人可以帮助我。我已经避免长时间寻求帮助，因为我确信这是一个愚蠢的错误。

controllers.ts

app.ts

execute 'chown a directory' do
  command 'chown -R user:group /path/to/directory 2>&-'
end

route.ts：

state('jobPost', {
              url: '/jobPost',
              templateUrl: "/templates/jobPost.html",
              controller: MyApp.Controllers.jobPostController,
              controllerAs: 'jobPost'
          })
          .state('editjobPost', {
              url: '/editjobPost',
              templateUrl: "/templates/jobPost.html",
              controller: MyApp.Controllers.jobPostController,
              controllerAs: 'jobPost'
          })

jobPost.html：

router.get('/jobPostData', function (req, res) {
  console.log('getting jobPost data');
  JobPost.find({}, function(err, jobposts) {
    res.json(jobposts);
  });
});

router.put('/jobPost', function (req, res, next) {
  console.log('editing jobPost');
  let jobPost = new JobPost({
    jobTitle: req.body.jobTitle,
    jobLocation: req.body.jobLocation,
    jobDescription: req.body.jobDescription,
    created_at: req.body.created_at
  });
  console.log(jobPost);
  jobPost.save(function(err, jobPost) {
    if (err) return next(err);
    console.log('edited post');
    res.send(jobPost);
  });
});

jobForm.ts：

****编辑以反映回答堆栈溢出核对表我已经尝试弄乱了JobPost.html中editJobPost部分的ui-sref和ng-click，这可能是路由错误。

然后我将controller.js中的editJobPost方法从JobPost变量更改为JobPosts变量。现在它运行并编译（之前没有）它会在控制台中抛出它：

$(document).ready(function() {
  $('.new_job_form').on('submit', function(e){
    e.preventDefault();
    var jobTitle = $('#jobTitle').val();
    var jobLocation = $('#jobLocation').val();
    var jobDescription = $('#jobDescription').val();

    $('#jobTitle').val('');
    $('#jobLocation').val('');
    $('#jobDescription').val('');

    var data = {
            jobTitle: jobTitle,
            jobLocation: jobLocation,
            jobDescription: jobDescription,
            };
    console.log(data);
    $.ajax({
          url: '/jobPost',
          dataType: "json",
          method: "POST",
          data: data,
          success: function(data, textStatus, jqXHR){
          console.log("Successfully saved to database",data);
          // var resultString = "<h4>"+data.jobTitle+"</h4><h4>"+data.jobLocation+"</h4><h4>"+data.jobDescription+"</h4>";
          // $('.postResult').html(resultString);
          },
          error: function(XMLHttpRequest, textStatus, errorThrown){
              alert("Status: " + textStatus); alert("Error: " + errorThrown);
          }
       });
  });
  angular.module('MyApp').controller('jobPostController', function ($scope, $log) {
    $scope.totalItems = 64;
    $scope.currentPage = 1;

    $scope.setPage = function (pageNo) {
      $scope.currentPage = pageNo;
    };

    $scope.pageChanged = function() {
      $log.log('Page changed to: ' + $scope.currentPage);
    };

    $scope.maxSize = 5;
    $scope.bigTotalItems = 175;
    $scope.bigCurrentPage = 1;
  });

});

我知道这意味着我声明的变量是未定义的，我只是不知道从哪里开始。有什么不对，为什么。
