hi ,
i have implemented search function which list out the streams when i
enter a string in the search text box.And here i am not using any
search button once i enter the string in the text box it will give the
results.
Now i want to do the search function by selecting the params from the
dropdown box and using seach button.
e.g:i have two dropdownboxes one is for name another is for resolution
,i can select the perticlar name and resolution from dropdown
boxes,now i want to search for this two strings matched in the tables
called streams.
How to link this dropdown box params as arguments to the search
function written in controller and index.html.erb?
Can you give any suggestions?
take a look at my code;
drop down box creation in index.html.erb
----------------------------
<%= select_tag 'parameter_name',
options_from_collection_for_select(Stream.find(:all), :id, :name) %>
<%= select_tag 'parameter_name',
options_from_collection_for_select(Stream.find(:all), :id, :resolution) %>
here i am to get the name and resolution params in dropdownboxes.
--------------------------------------------------------------------------------
below code gets the params to be seachd as arguments in observe_field
method,here i want to made changes to collect values from the drop
down boxes.
----------------------------------------------------------------------------------------------------------
<%= observe_field 'codecformat',
:frequency => 0.5,
:update => 'results',
:url => { :controller => 'streams', :action=>
'get_results' },
:with => "'search_text=' + escape(value)",
:loading =>
"document.getElementById('spinner').style.display='inline'",
:loaded =>
"document.getElementById('spinner').style.display='none'"%>
---------------------------------------------------------------------------------------------------------------------
