如何以编程方式制作Dojo dijit表单

require(["dijit/form/Form", "dijit/form/Button", "dijit/form/TextBox"], function(Form, Button, TextBox){
  var myForm = new Form({
    id: "myForm",
    action: "/submit",
    method: "post"
  }, "formNode");

  var firstNameTextBox = new TextBox({
    id: "firstName",
    name: "firstName",
    label: "First Name:",
    required: true
  }, "firstNameNode");

  var lastNameTextBox = new TextBox({
    id: "lastName",
    name: "lastName",
    label: "Last Name:",
    required: true
  }, "lastNameNode");

  var submitButton = new Button({
    label: "Submit",
    onClick: function(){
      if(myForm.validate()){
        myForm.submit();
      }
    }
  }, "submitButtonNode");
});

require(["dijit/form/TextBox"], function(TextBox){
  var myTextBox = new TextBox({
    id: "myTextBox",
    name: "myTextBox",
    label: "My Text Box:",
    required: true
  }, "myTextBoxNode");
});

require(["dijit/form/ValidationTextBox"], function(ValidationTextBox){
  var myValidationTextBox = new ValidationTextBox({
    id: "myValidationTextBox",
    name: "myValidationTextBox",
    label: "My Validation Text Box:",
    required: true,
    validator: function(value){
      if(!value){
        return false;
      }
      return true;
    }
  }, "myValidationTextBoxNode");
});

require(["dijit/form/Form", "dijit/form/Button"], function(Form, Button){
  var myForm = new Form({
    id: "myForm",
    action: "/submit",
    method: "post"

  var submitButton = new Button({
    label: "Submit",
    onClick: function(){
      if(myForm.validate()){
        myForm.submit();
      }
