我通过使用swift创建的API进行url调用,如下所示:

class API {

  let apiEndPoint = "endpoint"
  let apiUrl:String!
  let consumerKey:String!
  let consumerSecret:String!

  var returnData = [:]

  init(){
    self.apiUrl = "https://myurl.com/"
    self.consumerKey = "my consumer key"
    self.consumerSecret = "my consumer secret"
  }

  func getOrders() -> NSDictionary{
    return makeCall("orders")
  }

  func makeCall(section:String) -> NSDictionary{

    let params = ["consumer_key":"key", "consumer_secret":"secret"]

    Alamofire.request(.GET, "\(self.apiUrl)/\(self.apiEndPoint + section)", parameters: params)
        .authenticate(user: self.consumerKey, password: self.consumerSecret)
        .responseJSON { (request, response, data, error) -> Void in
            println("error \(request)")
            self.returnData = data! as NSDictionary
    }
    return self.returnData
  }

} …

我需要组合两个FormData对象并使用XMLHttpRequest发布它们.其中一个表单包含文件输入.

var formData = new FormData(document.forms.namedItem('form-ship'));
var poData = new FormData(document.forms.namedItem('po-form'));

// Combine them
var fData = $.extend(true, formData, poData);

当我使用$.extend或者如果我serialize()用来组合没有文件输入的表单时,它不起作用.知道怎么做吗？

我有一个围绕70个输入字段的大表单，并且表单中有一些可以创建其他输入字段的按钮。我的问题是，如果服务器在提交表单时出现问题（例如数据库插入失败），那么如何保留这些输入字段及其值？我具有动态验证功能，但是如果提交时出现问题怎么办？

有人可以解释我为什么当我这样做时,print_r($student->getStudents())我只获得数组的大小并is_array返回false.

这是我的输出

Jane Doe enrolled at Aviation High School
All students:

 class Student{

 public $students = array('Jason', 'Joe');

     $this->name = $name;
     $this->students = array_push($this->students, $name);
 }
 public function lastName(){
    return "Doe";
 }

 public function getStudents(){
    return $this->students;
 }
}
