What is the best way to invoke a method within the $http body in AngularJS

When I try to call the editopenComponentModal method in another method, I encounter the following error:

angular.js:13920 TypeError: Cannot read property 'editopenComponentModal' of undefined

   EditCurrentJob(job) {

          this.$http.put(properties.job_path + "/"+job.job_id).then(function successCallback(response) {
            console.log(response.data);
            this.current_job =  response.data;
            this.editopenComponentModal();

         }, 
          function errorCallback(response) {

          });
}

     editopenComponentModal() {
        var modalInstance = this.$uibModal.open({
          animation: this.animationsEnabled,
          template: require('./Report/editsubmittedinformation.html'),
          scope: this.$scope,
          size: 'lg'
        });
        this.$scope.modalInstance = modalInstance;

        return modalInstance.result;
      }

Answer №1

Utilize function references for this task, hopefully it will assist you.

var vm = this;
vm.editopenComponentModal = editopenComponentModal;
function UpdateCurrentJob(job) {

      $http.put(properties.job_path + "/"+job.job_id).then(function successCallback(response) {
        console.log(response.data);
        vm.current_job =  response.data;
        vm.editopenComponentModal();

     }, 
      function errorCallback(response) {

      });
}

 function editopenComponentModal() {
    var modalInstance = this.$uibModal.open({
      animation: this.animationsEnabled,
      template: require('./Report/editsubmittedinformation.html'),
      scope: this.$scope,
      size: 'lg'
    });
    this.$scope.modalInstance = modalInstance;

    return modalInstance.result;
  }

Answer №2

To display a modal following an $http.put request, simply execute the following code.

$('#success').modal();

In this case, 'success' refers to the id of the modal element.

Answer №3

Insert let self = this right before the this.$http.put(

Next, update these lines:

this.current_job =  response.data;

this.editopenComponentModal();

To:

self.current_job =  response.data;

self.editopenComponentModal();

Rationale: this in the callback has a different reference point, so by assigning it to a new variable, you can maintain access to the intended this.
