必须是简单的修复，但我一辈子都看不到我做错了什么。

我已经在在线测试器中测试了 reg 表达式并且它可以工作，所以假设它是 Flex 依赖的问题。

这是我的代码和跟踪输出 - 只是在我删除一个元素时尝试压缩一个字符串。

trace('Found Job To Delete:' + strJobToDelete);                         

strJobRegExp = "(" + strJobToDelete + "\\, )|(, " + strJobToDelete + ")|( " +  strJobToDelete + ")|(" + strJobToDelete + " )"
trace('Reg exp: ' + strJobRegExp);
findJobRegExp = new RegExp(strJobRegExp);                           
strJobNumList.replace(findJobRegExp, '');
trace('After Remove: ' + strJobNumList);

这是输出：

找到要删除的工作：0007-13

正则表达式： (0007-13\, )|(, 0007-13)|( 0007-13)|(0007-13 )

删除后：0007-13、0006-13

编辑后 ===> 新工作：0007-13、0006-13

您正在匹配空格或空格和逗号，但并非没有它们中的任何一个。

试试这个模式：

" 0007-13(?!,)|, 0007-13|0007-13,? |0007-13"

strJobRegExp = " #(?!,)|, #|#,? |#".replace(/#/g, strJobToDelete);

这(?!,)是一个否定的前瞻，并表示下一个位置不能有逗号。它不会消耗角色。

结果：

"0007-13"                     -> ""
"0007-13 0008-13"             -> "0008-13"
