保存到数据库是好的。
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
从数据库中检索会去掉我的反斜杠。
var emailReg = /^([w-.]+@([w-]+.)+[w-]{2,4})?$/;
我正在开发一个使用CodeIgniter的项目。我有一个验证电子邮件地址的表单，如果可以，则保存到数据库。我正在使用Tinymce textarea 编辑器，我将数据保存到这个数据库，我的页面显示正常。问题是当我将数据返回到 textarea 时，由于缺少反斜杠，验证不起作用。
我不确定它是来自CodeIgniter还是Tinymce的问题。
