jQuery变量名称后附有大量数字 [英] jQuery variable name appended with a large number

问题描述

我经常在我从公司媒体中心加载的代码中看到jQuery在控制台中通常不可用. (否$和jQuery)

I often see in my code I am loading from my company's media central that jQuery is not available in the console normally. (No $ and jQuery)

但是有时候，对于jQuery所附加的那些元素，它的数字很长.

But sometimes, to those elements to which jQuery is attached, it has a long number with it.

jQuery18306575689211022109_1378907534666

这样做的目的是什么?安全吗?

What is the purpose of doing this? Security?

此外，有时有时可以直接在控制台中使用jQuery，但只能使用上面的数字. 因此，我无法在需要使用jQuery查询的控制台中调试我的应用程序.

Also, jQuery is sometimes available directly in the console, but only with the above numbers. I am therefore unable to debug my apps in console, where I need to query using jQuery.

但是，在JavaScript代码中，jQuery完美地用作了$和jQuery.因此，我应用了一个断点并导出为window.jQuery = jQuery.

However, in the JavaScript code, jQuery is perfectly being used as $ and jQuery. So I apply a break-point and export as window.jQuery = jQuery.

当混淆了jQuery时，这是调试应用程序的正确方法吗?

Is this a proper way to debug the app, when jQuery is obfuscated?

更新:

例如，请检查此

For eg., check this URL the app is calling. It seems that the URL knows what is the number appended to jQuery. How do I come to know of the same number while debugging? Any lights on what is going on?

推荐答案

似乎您在混淆两个不同的变量.您可以在以下网站上进行快速测试: http://www.jquery4u.com/function-demos/jsonp/#demo .单击运行演示"，打开Chrome的控制台，键入"jQuery"以获取回调的名称，然后执行以下简单比较:

It seems that you are confusing two different variables. You can make a quick test on this website : http://www.jquery4u.com/function-demos/jsonp/#demo. Click "run demo", open Chrome's console, type "jQuery" in order to retrieve the callback's name, then perform this simple comparison :

jQuery16409391013463027775_1379048051365 === jQuery // false

也就是说，在您的情况下，名为"$"和"jQuery"的变量不可用的事实可能是由于特定的实现.一种可能是使用 jQuery.noConflict() ，它允许自定义用作对jQuery的引用，或从全局范围(window)中完全删除对jQuery的所有引用，因此无法在控制台中访问它.

That said, the fact that the variables named "$" and "jQuery" are not available in your case may be due to a specific implementation. One possibility could be the use of jQuery.noConflict() which allows either to customize the name used as a reference to jQuery, or to completely remove all references to jQuery from the global scope (window), so there is no way to access it in the console.
