Precautions for yui compressor

My js and css contacts include jsMin, jsPacker, yui compressor, and google Closure compress.

These compression comparison of many articles, of which google Closure compress many people advocate, I also recommend it, here YU Bo students summarized the yui compressor and google Closure compress comparison: http://www.slideshare.net/lifesinger/closure-compiler-vs-yuicompressor

 

Recently, I found that yui compressor2.4.2 has some problems in compressing and confusing js scripts, so I want to change it to google Closure compress immediately. However, I am lazy and don't want to change the content of the ant script for automated packaging. In addition, many compression tools I have not collected execution programs and cannot be executed automatically. Try the latest yui compressor version yui compressor2.4.7 In the lazy method. The problem is solved.

Here I found some precautions for yui compressor2.4.2 for reference only:

1) after compression obfuscation, You can manually or automatically write data at the beginning. "<! -- ", Write at the end" --> ". This is not the reason.

2) // "and" */"cannot be in the same row; otherwise, an error is returned.

For example:

Error:

/* Var s = 2;

Var m = 1; // define */

Correct:

/* Var s = 2;

Var m = 1; // define

*/

3) Chinese problems.

However, I found that some Chinese characters have problems (I have to go further here to find out the cause)

For example, var s = "" will report an error. If there is an error in "Multi-end" compression obfuscation, you can load a space behind the multiple to solve the problem.

But now, version 2.4.7 has been completely resolved. V5
