使用带有 Backbone 和 Requirejs 的 jQuery 插件

2022-01-11 00:00:00 jquery jquery-plugins javascript backbone.js requirejs

我正在使用主干+requirejs+jquery，但在我当前的 html 页面中加载 jquery 插件时遇到问题(确切地说是主干 html 模板).

I'm working with backbone+requirejs+jquery and I have a problem with jquery plugin loading in my current html page (backbone html template precisly).

有我需要的配置:

require.config({

  paths: {
    // ... some code about backbone config
    jquery: '/js/lib/jquery/jquery.min',
    'jquery.camera' : '/js/jquery/jquery.camera'
  },

  shim: {
    // ... some code about backbone config
    'jquery.camera': ['jquery']  
  }
});

在我的布局 html 页面中，我有:

In my layout html page I have:

<script type='text/javascript' src='/js/jquery/jquery.camera.js'></script>

在我的模板页面中，我有:

and in my template page I have:

<script type="text/javascript">
  jQuery(function() {

    jQuery('#test').camera({
...
</script>

最后是我的浏览器消息:

Finally my browser mesg :

Uncaught TypeError: Object [object Object] has no method 'camera'

你有什么想法吗?

同时我还有一个问题，在我们当前的页面中包含一些 js 代码的最佳方式是什么，包括主干、requirejs 等.

In the same time I have another question, what is the best way to include some js code in our current page with backbone,requirejs, etc.

谢谢:)

推荐答案

我解决了类似的问题(Jquery.cookie)，但我的问题是 Jquery 正在加载，然后 Jquery.cookie 被包含但已经需要将 JQuery 作为静态资源.

I solved a similar issue (Jquery.cookie) like this, but my problem was that Jquery was being loaded and then Jquery.cookie was being included but require already had JQuery as a Static resource.

像这样我将 Jquery.Cookie 传递给应用程序，它只在我的应用程序范围内插入 jquery.cookie.

So like this I pass Jquery.Cookie to the application and it inserts jquery.cookie in my application scope only.

require.config({

  paths: {
      'async'           : 'libs/async'
      ,'jquery'         : 'libs/jquery'
      ,'underscore'     : 'libs/underscore'
      ,'backbone'       : 'libs/backbone'
      ,'text'           : 'libs/text'
      ,'jquery.cookie'  : 'libs/jquery.cookie'   // <-- cookie lives here
  }

  ,shim: {
    'jquery': {
      exports: '$'
    }
    ,'underscore': {
      exports: '_'
    }
    ,'backbone': {
      deps: ['underscore', 'jquery'],
      exports: 'Backbone'
    }
    ,'jquery.cookie': {     //<-- cookie depends on Jquery and exports nothing
        deps: ['jquery']
    }
  }
});

然后在我添加的主 App 类中

and then in the main App class I added

require([
  'jquery'
  ,'underscore'
  ,'backbone'
  ,'mapApp'
  ,'jquery.cookie'   //<- this is the real trick !!!
],
  function ($, _, Backbone, App) {

在此之后我能够找到 jquery cookie.

After this I was able to find jquery cookie.

顺便说一句:如果您使用 Require.js 来获取它，则无需在 html 中导入 JQuery.camera，除非您在 Require.js 范围之外使用它.

BTW: there is no need to import JQuery.camera in your html if you are using Require.js to fetch it, unless you use it outside your Require.js scope.
