在打包的应用中使用dojo 1.8（uncaught unload在打包的应用中不可用） [英] Using dojo 1.8 in a packaged app (uncaught unload is not available in packaged apps)

问题描述

$ b

 
在我的打包应用程序中使用dojo取得了一些进展后，我又碰到另一个路障，我找不到任何文档。 >  {
 ... 
sandbox：{
pages：[test.html] 
}，
应用：{
background：{
scripts：[
background.js
] 
} 
} 
 } 
  

test.html从应用程序加载dojo以及我的一些模块，但是dojo解析页面的dom中，我收到了platformApp抛出的错误

  Uncaught unload在打包的应用程序中不可用。 platformApp：14 
（匿名函数）platformApp：14 
 Window.addEventListener platformApp：127 
 addListener dojo.js.uncompressed.js：15317 
 on.parse 
  

是否有任何CSP规则可以添加到沙盒中，以便这样做是正常的事情？

$ b $我希望Chrome默认是这样做的，而不是抛出一个错误......但这是我在加载dojo之前必须做的事情：

  //防止注册unload / beforeunload并发出警告，chrome会抛出异常。 
（function（）{
 var windowAddEventListener = Window.prototype.addEventListener; 
 Window.prototype.addEventListener = function（type）{
 if（type ==='unload' || type ==='beforeunload'）{
 try {
 throw new Error（'不要使用Window.addEventListener for'+ type）; 
} catch（e）{
 console.error（e.message，e）; 
} 
} else 
 return windowAddEventListener.apply（window，arguments）; 
}; 
}） （）; 
  

After finally making some progress in using dojo with my packaged app, I've hit another road block that I can't find any documentation for.

{
  ...
  "sandbox": {
     "pages": ["test.html"]
  },
  "app": {
    "background": {
      "scripts": [
        "background.js"
      ]
    }
  }
}

test.html loads dojo from the app as well as some of my modules, but as dojo parses the dom of the page, I get an error thrown by the platformApp

Uncaught unload is not available in packaged apps. platformApp:14
(anonymous function)                               platformApp:14
Window.addEventListener                            platformApp:127
addListener                                        dojo.js.uncompressed.js:15317
on.parse

Are there any CSP rules I can add to the sandbox to let this do it's normal thing?

解决方案

I wish that chrome did this by default instead of throwing an error... but this is what I had to do before I loaded dojo:

// Prevent registrations for unload/beforeunload and warn, chrome will throw exception.
(function() {
  var windowAddEventListener = Window.prototype.addEventListener;
  Window.prototype.addEventListener = function(type) {
    if (type === 'unload' || type === 'beforeunload') {
          try {
        throw new Error('Do not use Window.addEventListener for ' + type);
      } catch (e) {
        console.error(e.message, e);
      }
    } else
      return windowAddEventListener.apply(window, arguments);
  };
})();
