问题描述

我将在require js中定义我的模型，并且我需要淘汰赛和，还有jquery.

I am going to define my model in require js and i need knockout and knockout validation plugin in my module and also jquery .

define(["knockout","jquery","knockout.validation"], function (ko,$,validation) {
  // knockout model here with some knockout validation 

    return function SignUpViewModel() {
    var self = this;
    self.name = ko.observable();
    self.email = ko.observable().extend({ required: true });
    self.password = ko.observable().extend({
       required: true,
       minLength: 6
   });
   self.confirmPassword = ko.observable().extend({ mustEqual: self.password() });
   self.company = ko.observable();
   self.availableCountries = ko.observableArray(['Pakistan', 'USA', 'Egypt', 'UAE']);
   self.selectedCountry = ko.observable();
   self.errors = ko.validation.group(self);
   }           
 });

但是当我运行它时，出现以下错误.

But when i run this i got the following error .

Uncaught ReferenceError: ko is not defined

我还尝试调试，发现所有其他库knockout，jquery都正在完美加载.

i also try to debug and found that all other librariesknockout, jquery are loading perfectly .

这是我的配置部分

require.config({
  baseUrl: "/Scripts",
  paths: {
    "Signup" : "Signup",
    "knockout": "knockout-2.3.0",
    "knockout.validation": "knockout.validation",
    "jquery": "require-jquery"
    }
});

推荐答案

您的模型可以正常使用，这是我的require config:

Your model works fine with me, here's my require config:

requirejs.config({
  baseUrl: '/Scripts',
  paths: {
    'jquery': 'jquery-1.9.1.min',
    'knockout' : 'knockout-2.3.0',
  }
});
// myModel.js is the file containing your model code.
require( ["myModel", "knockout"], function(model, ko){
  ko.applyBindings(new model());
});

myModel.js

define(["knockout","jquery","knockout.validation"], function (ko,$,validation) {
// knockout model here with some knockout validation 

  return function SignUpViewModel() {
    var self = this;
    self.name = ko.observable();
    self.email = ko.observable().extend({ required: true });
    self.password = ko.observable().extend({
       required: true,
       minLength: 6
    });
    self.confirmPassword = ko.observable().extend({ mustEqual: self.password() });
    self.company = ko.observable();
    self.availableCountries = ko.observableArray(['Pakistan', 'USA', 'Egypt', 'UAE']);
    self.selectedCountry = ko.observable();
    self.errors = ko.validation.group(self);
  };           
});

，您不再需要require-jquery，因为 jQuery定义了名为AMD模块'jquery' (全部小写)，当它检测到AMD/RequireJS时.
