Re: Restric the values in S:TextFields.
On the server-side, use an expression validator to ensure the input contains only valid characters. On the client-side either: - use ajax validation; or - use a javascript function that listens for the keypress event and rejects invalid keystrokes As usual, the javascript keypress event on IE is different from all other browsers so the function has to include browser detection. Here is the gist of what you need: s:textfield name=x onkeypress=filterKeypress() ... javascript: function filterKeypress(e) { var accept = /[\d|\+|\-|\.]/; // a regex pattern of accepted chars var keyChar; if (msie) { // use your favourite broswer detection function keyChar = String.fromCharCode(e.keyCode); } else { keyChar = String.fromCharCode(e.which); } // check if the character is acceptable if (!accept.test(keyChar)) { e.preventDefault(); // if it's not, prevent the keypress event from proceeding } } Sanjeewa Saman wrote: Hi all , Can some body please tell me a way to restrict the data that we can eneter to a textfield in struts2.

Thank you very much Jeromy , It works I used the java Scripts for this to validate in client side. sanjeewa -Original Message- From: Jeromy Evans [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 27, 2008 1:44 PM To: Struts Users Mailing List Subject: Re: Restric the values in S:TextFields.

Depending on how important the data is and how public the site is, also consider validating it on the server-side in case of users without javascript and the common idiot. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Restric the values in S:TextFields.
Hi all , Can some body please tell me a way to restrict the data that we can eneter to a textfield in struts2. What I wanted to do is , for the s:textfield , I need to enter only values these values {1-10 , +,-,.} . Thank you. sanjeewa
RE: Restric the values in S:TextFields.
Yes Chris , that can be done using JS , But I thought that there should be a way in struts2 to that. May be some one have an idea of doing it.If so pls give ur idea to us.

(*Chris*) If it's unacceptable for the user to even be able to type in 'invalid' characters then yes. If it's OK to let them type anything but then notify them after the fact that what they entered isn't acceptable, there are a few more options. If it's OK for that notification to be produced as part of the server-side validation when the form is submitted and redisplayed, it's as easy as using a regex validation rule. So, sanjeewa, it depends on your exact requirements. I would start by adding in server-side validation (since that should be there anyway) then look at adding additional, client-side Javascript checking/reporting afterwards if you still feel you need it.
