Hi,

....
 ... \<%= text\_field\_tag :search, params[:search], :id=\>"search\_field", :value=\>params[:search] %\> ...

Just wondering how I would clear the value for the text\_field\_tag,

Thanks!!

if you were using a form\_remote\_tag you could always say :complete =\>  
‘document.getElementById(“search\_field”).value = “”’

\<% form\_remote\_tag update =\> “id\_of\_div\_to\_update”, :url =\> { :action =\>  
:method\_call}, :complete=\>  
‘document.getElementById(“search\_field”).value = “”’ do -%\>

…

\<% end -\>
