Prototype ajax/javascript q

Rails
1

I’m trying to send to my application the coords x,y on an “input type
image” in a html form, but x,y variables are not present in the
POST_DATA (are not submitted). Any other field (hidden inputs) are being
sent when I click on the image input form field.

I use rails 1.0 and prototype 1.4, browsers Seamonkey
2.0, Firefox 1.x and Konqueror, Linux, and I’m just a newbie in ror.

Html code generated by rails:

In POST_DATA I have ‘’.

Tried it without ajax:

In POST_DATA i have matrix.x=572&matrix.y=443.

Hints, anyone? The code in the rhtml template is:

<%= form_remote_tag(:update => “coords”,
:url => { :action => “set” }) %>

<%= end_form_tag %>

My guess is that Form.serialize (in prototype.js) ignores
You could modify Form.Element.Serializers (input) and add the desired
behaviour for type “image”

Your guesss is be right. But after some reading, i found out that x,y
coordinates of the click are not available in the forms objects, so
can’t use . I’ll try something else.

Form.Element.Serializers = {
input: function(element) {
switch (element.type.toLowerCase()) {
case ‘submit’:
case ‘hidden’:
case ‘password’:
case ‘text’:
return Form.Element.Serializers.textarea(element);
case ‘checkbox’:
case ‘radio’:
return Form.Element.Serializers.inputSelector(element);
}
return false;
},
