validate a textbox using javascript

Tags: Javascript, .NET
I need to validate a textbox where the user will know immediately if the text is correct. For example, if the user types in the wrong value, he will immediately see a popup or something telling him that the value is not correct and it wont let him procede.  If the value is correct, then nothing happens and the user can procede by clicking "next".

I have a textbox <asp:textbox id="secret" runat="server"</asp:textbox>
And the only input that will be allowed is the number "559".

Thanks.

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is.
