BlackBird, G. Scott Olson開(kāi)發(fā)的javascript日志記錄庫(kù)，相當(dāng)于java中的log4j, javascript開(kāi)發(fā)者再也不用使用alert來(lái)調(diào)試?yán)病?
以下是具體的操作說(shuō)明：
Html代碼

復(fù)制代碼代碼如下:

 
<html> 
<head> 
<script type="text/javascript" src="/PATH/TO/blackbird.js"></script> 
<link type="text/css" rel="Stylesheet" href="/PATH/TO/blackbird.css" /> 
... 
</head> 
</html> 
<html> 
<head> 
<script type="text/javascript" src="/PATH/TO/blackbird.js"></script> 
<link type="text/css" rel="Stylesheet" href="/PATH/TO/blackbird.css" /> 
... 
</head> 
</html> 

Blackbird有一個(gè)簡(jiǎn)單的方法將返回值發(fā)送到控制臺(tái)：
Javascript代碼

復(fù)制代碼代碼如下:

 
log.debug( 'this is a debug message' ); 
log.info( 'this is an info message' ); 
log.warn( 'this is a warning message' ); 
log.error( 'this is an error message' ); 
log.debug( 'this is a debug message' ); 
log.info( 'this is an info message' ); 
log.warn( 'this is a warning message' ); 
log.error( 'this is an error message' ); 

這個(gè)方法的好處是，所有這些公共的方法都能獨(dú)立的現(xiàn)實(shí)數(shù)據(jù)?？梢院苋菀椎拇_定發(fā)送郵件的類型：
