requirejs – Require,Knockout和pager是Undefined TypeError

2023年2月8日 284次阅读

我有以下主要内容：

requirejs.config({
  paths:{
    'text':'../vendor/js/text.min',

    'jquery':"../vendor/js/jquery.min",
    'boostrap':"../vendor/js/bootstrap.min",
    'ko':"http://knockoutjs.com/downloads/knockout-3.4.0.debug",
    'pager':"../vendor/js/pager",

    'imageGroupsVm':'../js/viewModels/imageGroupsViewModel',
    'panelVm':'../js/viewModels/panelViewModel',

    'compMessage':'../js/components/message',
    'extBooleanToggle':'../js/extenders/booleanToggle'
  },
  shim:{
    'bootstrap':['jquery'],
    'pager':['ko'],
    },
  waitSeconds: 200,
});

define(['jquery','ko','pager','panelVm'],function($,ko,pager,panelVm)
{
    pager.extendWithPage(panelVm);
    ko.applyBindings(panelVm);
    pager.start();
});

但由于某种原因,我收到以下2条错误消息：

更多详情panelViewModel.js包含：

define(['ko','imageGroupsVm','compMessage'],function(ko,ImageGroupsVM,loginViewModel)
{
  var image_groups=new ImageGroupsVM();


  return {'imageGroups':image_groups};
});

ImageGroupsViewModel包含：

define(['ko','jquery'],function(ko,$)
{
  console.log(ko);
  return function imageGroupsViewModel()
  {
    var self=this;

    self.albums=ko.observableArray();

    self.init=function()
    {
      self.albums([]);

      self.fetchData();
    }

    self.fetchData=function()
    {
      console.log("Data Fetched");
    };

    function Album(data)
    {

    }
  };
})

我拥有的所有JS文件都是:(注意锡供应商类是我加载的外部库)

《requirejs – Require,Knockout和pager是Undefined TypeError》

最佳答案 我设法通过在需要的时候用’knockout’替换’ko’来解决它.

更具体地说,在main(您在html上的data-main中包含的文件)

以下行：

'ko':"http://knockoutjs.com/downloads/knockout-3.4.0.debug",

改变成：

'knockout':"http://knockoutjs.com/downloads/knockout-3.4.0.debug",

我包括在垫片中：

'pager':['knockout'],

而且

define(['jquery','ko','pager','panelVm'],function($,ko,pager,panelVm)

改变成

define(['jquery','knockout','pager','panelVm'],function($,ko,pager,panelVm)

因此我的主要是：

requirejs.config({
  paths:{
    'text':'../vendor/js/text.min',

    'knockout':"https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.0/knockout-min",
    'pager':"../vendor/js/pager.min",
    'jquery':"../vendor/js/jquery.min",
    'boostrap':"../vendor/js/bootstrap.min",

    'imageGroupsVm':'../js/viewModels/imageGroupsViewModel',
    'panelVm':'../js/viewModels/panelViewModel',

    'compMessage':'../js/components/message',
    'extBooleanToggle':'../js/extenders/booleanToggle'
  },
  shim:{
    'pager':['knockout'],
    'bootstrap':['jquery'],
    },
  waitSeconds: 200,
});

define(['jquery','knockout','pager','panelVm'],function($,ko,pager,panelVm)
{
    pager.extendWithPage(panelVm);
    ko.applyBindings(panelVm);
    pager.start();
});

另外在我的项目中加载的其他javascript文件需要我更改了行：

define(['ko',...,'other_lib'],function(ko,....,other_lib)

附：

define(['knockout',...,'other_lib'],function(ko,....,other_lib)

注意：
我还改变了我在其他页面加载的其他main.js上的theese行：

'ko':"http://knockoutjs.com/downloads/knockout-3.4.0.debug",

改变成：

'knockout':"http://knockoutjs.com/downloads/knockout-3.4.0.debug",

我这样做是为了加载我使用require制作的所有模块.
