Hello All, This is my first post. I have a form element like... <input type="text" name="mycomment" id="mycomment"> I would prefer to not have the id in the form. If I remove it the dollar function doesn''t work anymore (for obvious reasons) is there another way to grab the object? I would rather code it as... <input type="text" name="mycomment"> Thanks for any help/direction.

Thanks Ken,
I am also in the habit of not naming my forms. So this solution would
involve naming the forms. Something I have done in the past. It seems
to me this would be common for someone to want to $() a form element,
but alas I hear no other solutions.
I have another question while were on the topic of forms.
I am building my parameters to pass to my ajax request like...
var pars = ''?ajaxrequest=''+$F(''mycomment'');
And it "mostly" works. How would I urlencode
$F(''mycomment'')?
Thanks for any help
Terry

For instance: $$(''form[action="/contact"] input[name="email"]'')[0] would return you the input field named "email" from the form that has the action set to "/contact". If you already have the (extended) form object, you could use: f.down(''input[name="email"]'') for the same purpose. To simplify it, here''s a possible variation: // add your method to "Form.Methods" Object.extend(Form.Methods, { getElement: function(form, name) { form.down( ''*[name="'' + name + ''"]'' ); } }); // apply new method to "Form" elements Object.extend(Form, Form.Methods); and now you''ll be able to use: var emailField = f.getElement(''email''); IAE, "getElement" is a bad name, as Prototype folks may choose to use it for something else in the future, choose your own "tricky" name ;-) OTOH, OFC, you could always use Ken''s advice going down the "elements" path as it should be more efficient for nowadays browsers.> I am building my parameters to pass to my ajax request like... > var pars = ''?ajaxrequest=''+$F(''mycomment'');YA bad (YMMV) habit :)) Prototype can help you big time with this kind of things. Please (re)read Prototype''s introductory article to "ajax" [2], especially the "Parameters and the HTTP method" section. Briefly, Prototype will handle all your parameters encoding.>> And it "mostly" works. How would I urlencode $F(''mycomment'')? > ahhh just found it its... escape()Do yourself a favor, NEVER - I mean it - NEVER use (un)escape!
