Question

必须简单修复，但我无法看到我的生活中我做错了什么。

我在在线测试仪中测试了reg表达式并且它有效，所以假设它是Flex依赖的问题。

这是我的代码和跟踪输出 - 只是在删除一个元素时尝试压缩字符串。

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

Reg exp：（0007-13 \，）|（，0007-13）|（0007-13）|（0007-13）

删除后：0007-13,0006-13

编辑后===＆gt;新工作：0007-13,0006-13

Answer 1

您与空格或空格和逗号匹配，但不是没有任何一个。

请尝试使用此模式：

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

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

(?!,)是一个负面的预测，并表示下一个位置一定不会有逗号。它不消耗角色。

<强>结果：

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