Hello all

I have very strange issue with my code.

i have a select tag, onchange it is calling a function. but i want to pass selected value from drop down in that function. But that function is already performing few actions, so I have to use overwrite_params. please look at following code:

select_tag('srtType', options_for_select(['Sort By', 'Price', 'Title', 'date']),             {                 :onchange => remote_function(                     :url=> { :controller => 'listings', :action => :search_results, :overwrite_params => { :srtType => "this.value"] }} ,

                    :method => "'post'" )             }         )

overwrite_params => { :srtType => "this.value"] } is not passing selected value. it is passing it as string.

Please advice.

hi, you should use use "with" parameter to send javascript values.

Here is the how to do it :

select_tag('srtType',             options_for_select(['Sort By', 'Price', 'Title', 'date']),             {:onchange => remote_function(               :url=> {                 :controller => 'listings', :action => :search_results}, :with => "{srtType:this.value}", :method => :post )})

Hello

unfortunately i am unable to do so, because there are some parameters in search_results which i want to keep and overwrite one particular.
