js 代码
var testStr = "now test001 test002";   
var re = /test(\d+)/ig;    
var r = "";   
while(r = re.exec(testStr)) {   
    alert(r[0] + "  " + r[1]);   
}  
此外也可以用testStr.match(re)，但是这样的话就不能有g的选项，而且只能得到第一个匹配。
另外备忘一下：

vim中设置了autoindent后，粘帖带缩进的代码会造成多余的缩进。 用下面的代码解决这个问题

:r! cat 
//and then paste ( shift + insert ) the content, and CTRL+D.

# 8th November, 2009
# update manager failed, giving me the error:
#       'files list file for package 'xxx' is missing final newline' for every package.
# some Googling revealed that this problem was due to corrupt files(s) in /var/lib/dpkg/info/
# looping though those files revealed that some did not have a final new line
# this script will resolve that problem by appending a newline to all files that are missing it
# NOTE: you will need to run this script as root, e.g. sudo python newline_fixer.py
