撼动正则表达式天地?!
谁能给出下面正确的解呢
如下的代码，如何用正则表达式正确的去除注释:
var kk = "// sljdfljsdf "; // *skldflsfllk "sdlf//sdfdsf "
var kk = "// sljdfljsdf "; // *skldflsfllk "sdlf//sdfdsf "
var kk = "// sljdfljsdf "; // *skldflsfllk "sdlf//sdfdsf "
var kk = "// sljdf/*sdf*/ljsdf '; // *sk/*fdsf*/ld " "flsfllk "sdlf//sdfdsf "
var kk = '// sljdf/*sdf*/ljsdf '; // *sk/*fdsf*/ld " "flsfllk "sdlf//sdfdsf "
var kk = '// sljdf/*sdf*/ljsdf '; // *sk/*fdsf*/ld " "flsfllk "sdlf//sdfdsf "

不明白！// 后面的不都是注释吗？
[解决办法]
关键是 "的处理，呵呵
[解决办法]
kk.replace(/^\/\/\\*w+$/, ' ');
不知道行不！！！
[解决办法]
正则表达式如下：
//(? <=;\s*//)[^\n]+

楼上的就可以,以分号为分界点.

js不支持反向预搜索

不懂,顶一下.

var reg = /([^ ' "\/\n]*([ ' "]?).*?[^\\]\2(?:\s*;\s*|\s+))(?:\/\/.*|\/\*.*\*\/\s*)(\n|$)/g;
var kk = document.getElementById( "text ").innerText;
alert( "处理前：\n " + kk);
alert( "处理后：\n " + kk.replace(reg, "$1$3 "));
