I need to ask to my user if will pay a service with credit card...if it checked the option pay_with_card? it must show the rest of the form, that ask for other data like card number, mail, etc. if the user don't checked it, it must show a message, the question is...how can I do this? thanks in advance
<%= form_for(@product) do |f| %>
<%= f.label :pay_with_card? %>
<%= f.check_box :pay_with_card,{}, "Yes", "No"%>
<div>
<%= f.label :card_number %> <%= f.text_field :card_number %>
</div>
<div>
<%= f.label :mail %> <%= f.text_field :mail %>
</div>
<% end %>
Make the card number/mail details div style="display:none;", then add some javascript to the checkbox to change it to display:block;
Something like this:
<%= form_for(@product) do |f| %>
<%= f.label :pay_with_card? %>
<%= f.check_box :pay_with_card,{}, "Yes", "No"%>
<div id="card_details" style="display:none;">
<%= f.label :card_number %> <%= f.text_field :card_number %>
<%= f.label :mail %> <%= f.text_field :mail %>
</div>
<% end %>
<script type="text/javascript">
var checkbox = document.getElementById('product_pay_with_card');
var details_div = document.getElementById('card_details');
checkbox.onchange = function() {
if(this.checked) {
details_div.style['display'] = 'block';
} else {
details_div.style['display'] = 'none';
}
};
</script>
