在IE6中打包/精简的javascript失败 - 如何调试？ [英] Packed/minified javascript failing in IE6 - how to debug?

问题描述

我有一些文件，我结合和打包生成一个单一的，最小化的JS文件。问题是，当我将文件缩小（使用打包程序）时，IE6提供了其特色有用的功能错误消息。

 行：12 //当然，第12行是空行
 Char：1 
错误：预期'）'
代码：0 
  

事情是：它工作IE7，Firefox和Chrome中的IE浏览器的问题只出现在IE6上。

解压缩后，我有近200kb的脚本通过8个文件传播。如何解决这个问题？

解决方案

您是否已经验证了未分解的代码可以在IE6中成功运行？如果是这样，因为这是一个语法错误而不是运行时错误，我将采取的下一步是开始减少一半的JavaScript，将其缩小，并查看问题停止报告的时间。然后从那里继续二进制搜索。

I have a number of files which I combine and pack to produce a single, minified JS file. The problem is that when I minify the file (using packer), IE6 gives one of its characteristic helpful error messages.

Line: 12      // of course, line 12 is an empty line
Char: 1
Error: Expected ')'
Code: 0

The thing is: it works fine in IE7, Firefox and Chrome the problem only comes up for IE6.

Unpacked, I have almost 200kb of scripts spread through 8 files. How on earth do I fix this?

解决方案

Have you already verified that the un-minified code can run successfully in IE6? If so, because this is a syntax error and not a runtime error, the next step I'd take is start halving the javascript, minifying it, and seeing when the problem stops being reported. Then continue binary searching from there.
