Tinymce编辑器检索数据从数据库问题[striping反斜杠]

保存到数据库是好的

var emailReg = /^(['w-'.]+@(['w-]+'.)+['w-]{2,4})?$/;   

从数据库中检索我的反斜杠。

var emailReg = /^([w-.]+@([w-]+.)+[w-]{2,4})?$/;

我正在做一个项目，我使用CodeIgniter。我有一个表单，验证电子邮件地址，如果ok，然后保存到数据库。我正在使用Tinymce textarea编辑器，我将数据保存到这个db和我的页面显示ok。问题是，当我得到我的数据回到文本区，验证不工作，因为缺少反斜杠。

我不确定它是否来自CodeIgniter或Tinymce。
