Regarding JavaScript onChange validation

[Hozaifa Azmi]

Dear All...


Kindly, let me know how can I implement JavaScript in a JSF page ?

I have three input text fields, userid, Name, & E-mail id;
I need to implement JavaScript onChange validation, i.e
if the user inputs Characters in the userid input field & moves to next
input field, he should get the error message "User Id can't be characters".
without clicking the submit botton.

Similar validations for other input fields, name & e-mailid.

kindly, put the code.


Thank you in advance,
H.N. Azmi

Javascript runs at the client side and intercepts on HTML only.
JSF runs at the server side and produces HTML output.

So when writing Javascript for JSF, you should ignore the JSF code and only concentrate on its HTML output. Open up a JSF page in your favourite webbrowser, view its page source and base your Javascript on it.

Hi Bauke Scholtz...

will you please post the JavaScript code for the above mentioned validations.

No, I will not. Hire a Javascript developer, or follow a Javascript course/book yourself, or try a Javascript forum where in you post the question the smart way.
