为了降低http请求，我将所有javascriupt合并为一个整齐的文件！我坚持删除评论/* comments */和// comments。我的水平远远低于缩小或解析的东西。我知道如何制作通心粉串。什么比这更复杂，你会不会在我的电脑或厨房发现，SO：REGEX：如何使用PHP代码从javascripts中删除评论

问题

同时它组合成一个文件，我想删除所有的意见。
这是什么正确的正则表达式？

<?php 
header('Content-type: text/javascript');  
$offset = 60 * 60 * 24; // Cache for a day 
header ('Cache-Control: max-age=' . $offset . ', must-revalidate'); 
header ('Expires: ' . gmdate ("D, d M Y H:i:s", time() + $offset) . ' GMT'); 

ob_start("compress"); 
function compress($buffer) { 

# NOT SURE, not all new lines are removed?? 
# remove tabs, spaces, newlines, etc. 
$buffer = str_replace(array("\r\n", "\r", "\t", ' ', ' '), '', $buffer); 

# WORKS !!! 
# remove comments/XXXXXXX 
$buffer = preg_replace('(// .+)', '', $buffer); 

######################################################################## 
# !! STUCK HERE !! OUTPUT FILE LOOKS OK BUT WEBSITE DOESNT LOAD OK IF THIS IS ON 
# remove comments/* XXX (enters etc) XXXX */
# $buffer = preg_replace('#/\*(?:.(?!/)|[^\*](?=/)|(?<!\*)/)*\*/#s', '', $buffer); 
########################################################################   

return $buffer; 
} 

include('../file1.js'); 
include('../file2.js'); 
ob_end_flush(); 
?>

这将是巨大的，如果它会赶上并删除以下：

/* XXXX */ 

/* 
    XXXX 
    XXXX 
*/

这就是所有！不能得到什么的正则表达式我有这个令人难以置信的工具，在这里我找到了正确的比赛甚至用它来nomatter工作：

RegExp: /\/\*(?:.(?!/)|[^\*](?=/)|(?<!\*)/)*\*\//gs 
pattern: \/\*(?:.(?!/)|[^\*](?=/)|(?<!\*)/)*\*\/ 
flags: gs

使用正则表达式是不删除的Javascript的最有效的方法注释。你需要一个字符串解析器和缩小器。见http://razorsharpcode.blogspot.com/2010/02/lightweight-javascript-and-css.html

如果坚持正则表达式模式，想想你将如何分析包含在所有没有使用Javascript评论这个简单的代码：

var regex=/(ftp|https?):\/\//; alert('hello, world'); return regex;

通知alert()之前的双斜线。一个使用正则表达式的愚蠢分析器会将有效的Javascript代码视为注释！

我第二个这个建议; @Sam：如果你想优化你的反应，你应该考虑使用缩小词代替自定义评论删除者。 Google Closure编译器，YUI压缩器或[Uglify JS]（https://github.com/mishoo/UglifyJS）应该是您的首选工具。 – 2010-12-10 07:31:46

谢谢大家，但看起来吓人的OMG难！我的主要目标是减少HTTp请求。与此同时，我想为什么不减少评论。这对我来说真的是OKA了。我认为现在不是最完美/最快的，但我明白，并可以增长与 – Sam 2010-12-10 08:40:11

我打了一个场景，我通过xhr在网络上加载javascript代码，并且需要清理代码以进行评估。我使用此代码：

var cleanCode = function cleanCode(input) { 
    // Remove special characters: 
    return input.replace(/\/\/[^"'].*?\n/g, '') /* //comments, but ignore a "//" if there is a quote after it */ 
       .replace(/\n/g, '')    /* Leftover newlines */ 
       .replace(/\r/g, '');   /* Carriage returns */ 
};

我测试用这个和唯一的问题我很喜欢评论：

//'key': 'value'

所以我不得不代码更改为内注释：

/*'key': 'value'*/ //LEAVE as inline comment, please

此代码没有得到改变：

url += '//' + ...

随意编辑/建议编辑，使其更具可读性。

模式的删除注释在JS

$pattern = '/((?:\/\*(?:[^*]|(?:\*+[^*\/]))*\*+\/)|(?:\/\/.*))/';

模式在CSS

$pattern = '!/\*[^*]*\*+([^/][^*]*\*+)*/!'; 

$str = preg_replace($pattern, '', $str);

我希望上面应该帮助别人删除评论..

我只是为了好玩测试此（var regex=/(ftp|https?):\/\//;alert('hello,world');）这 /* foo(); // some comment */这："Python's division: 1 // 2" 这//"you dope"例如和我的压缩编码那些不会破坏上面的例子！上面的评论:( 一个愚蠢的解析器，使用正则表达式将视为有效的JavaScript代码作为注释！）所以也许你也可以用正则表达式写没有愚蠢的解析器???

我关闭粗不是一个程序员只是想使插件工作就像我希望它.... 请随意发表评论，如果你找到一个问题，此脚本与有效的JavaScript语句。任何种类的评论标签结合（或不结合），它不能正确解决.. 因为我确实有一个大handycap我现在没有任何Javascript语法所以我不知道会发生什么我只是测试它我能找到的例子！

更新后的需求不再需要测试8000.000行现在工作正常。
