<% end %>

i want when i start typing in the text 开发者_Python百科field the site wil refresh. how can i do it?

If you mean to just add extra HTML attributes to the element generated by text_field_tag, you can pass them as a hash.

<%= text_field_tag(:q, :onkeyup => 'myJSFunctionToHandleStuff()') %> 

Hash arguments other than :disabled, :size, :maxlength, :placeholder are treated just as passthrough HTML attributes onto the generated input element
