Hi Friends, I am a newbie on ROR, I made a authentication page for login. Now For Validation at client side I want Javascript to be used. Does Rails support client side vaildation as for server side methods are already available? Regards HUNT -- Posted via http://www.ruby-forum.com/.
Rails obviously support client side validation. all you need is to put
onsubmit event on whatever the form syntax you are using. below is an
example:
<% form_tag ({:action => "new"}, {:onsubmit => "return
validate();"}) %>
then your basic javascript goes like:
function validate(){
if(document.getElementById(''some_id'')=="")
alert("specify first name");
}

You can put it anywhere.. in the index.html.erb or in layouts or in some external javascript.. in third case make sure that you are calling that javascript like <script src="/javascripts/yourjavascriptname.js"> On Wed, Sep 9, 2009 at 12:14 PM, HUNT HUNT <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > Puneet Pandey wrote: > > Rails obviously support client side validation. all you need is to put > > onsubmit event on whatever the form syntax you are using. below is an > > example: > > > > <% form_tag ({:action => "new"}, {:onsubmit => "return validate();"}) %> > > > > then your basic javascript goes like: > -------------------------------------------------------------------------- > > function validate(){ > > if(document.getElementById(''some_id'')=="") > > alert("specify first name"); > > } > > > > > Thanks Puneet, > > WHere this validate function is embedded in index.html.erb? > Any reference for the same is a great hint. > ------------------------------------------------------------------------- > > On Wed, Sep 9, 2009 at 11:46 AM, HUNT HUNT > > <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org > >> wrote: > > > >> Regards > >> HUNT > >> -- > >> Posted via http://www.ruby-forum.com/. > >> > >> > > >> > > > > > > -- > > Thanks and Regards > > > > ___________________ > > > > Puneet Pandey > > Ruby on Rails Developer > > http://www.puneetitengineer.wordpress.com > > In Puneet''s Lab: http://www.puneetpandey.com > > -- > Posted via http://www.ruby-forum.com/. > > > >-- Thanks and Regards ___________________ Puneet Pandey Ruby on Rails Developer http://www.puneetitengineer.wordpress.com In Puneet''s Lab: http://www.puneetpandey.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Ideally, javascript should be kept in head section of html, and for this you can use content_for tag.

They recommend combining multiple script resources into one, minifying etc. I take putting the javascript at the bottom as putting the script tags referencing the separate script resource(s) at the bottom not inlining javascript in the page. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale
