oncopy="return false；" oncut="return false；" 防止复制

弹出窗口

禁止输入特殊字符正则表达试：
^(?:[\u4e00-\u9fa5]*\w*\s*)+$
过虑非法字符的函数：
public string CheckStr(string str)
{
str = str.Replace("<", "<");
str = str.Replace(">", ">");
str = str.Replace("'", "''");
str = str.Replace(" ", " ");
str = str.Replace("\n", "<br/>");
str = str.Replace("\r\n", "<br/>");
str = str.Trim();
return str;
}
