Binding KeyUp event to Input Field
I am dynamically generating textboxes in ruby using
6,:maxlength => 5) %>it generates following HTML markup
Another set of textboxes:
6,:maxlength => 5) %>it generates following HTML markup
I have one more textbox:
.....
I want to update id="rating_factor_" textboxes as the val开发者_运维知识库ue in either id="multiple" textbox changes or id="relative_factor_" textboxes changes.
E.g. id="multiple" textbox = 5
id="relative_factor_" value= 0.0 textbox = 1
id="relative_factor_" value= 1.0 textbox = 2
id="relative_factor_" value= 2.0 textbox = 3
id="relative_factor_" value= 3.0 textbox = 4
id="relative_factor_" value= 4.0 textbox = 5
I want to show (multiple multiple and relative_factor_ and show)
id="rating_factor_" value= 0.0 textbox = 5
id="rating_factor_" value= 1.0 textbox = 10
id="rating_factor_" value= 2.0 textbox = 15
id="rating_factor_" value= 3.0 textbox = 20
id="rating_factor_" value= 4.0 textbox = 25
Now if user changes,
id="relative_factor_" value= 1.0 textbox as 1.5
then
id="rating_factor_" value= 1.0 textbox should be updated as 7.5
To achieve above goal, I tried binding #relative_factor_ to keyup event but as id is same for all i.e.#relative_factor_, it returns value for first textbox i.e. id="relative_factor_" value= 0.0.
Please guide me to crack this problem.
Thanks in Advance.
IDs are supposed to be unique
! You can't have all your text fields sharing the relative_factor_
id.
You can do something like
<% 0.upto(4) do |i| %>
<%= text_field_tag('relative_factor[][i]', @prefill_values[:relative_factor][i],
:size => 6,:maxlength => 5) %>
<% end %>
