Hi all,

I used observe field in my site as

<%=text_field :one,:new_col%>
<%= observe_field(: :one_new_col,
          :url => { :action => :live_search }),
          :frequency => 0.5,
          :update => :hits,
          :with => 'query'
          %>

And I got the javascript error as

element.tagName is undefined

Please give the solution.

Thanks
Bava

Hi Bava, what field are you trying to observe?  

<%=text_field :one,:new_col %>

=>  <input id="one_new_col" name="one[new_col]" size="30" type="text" /> 

Next, are you creating or updating a model?  If you're not, then I would recommend using

<%=text_field :one_new_col %>

=>  <input id="one_new_col" name="one_new_col" type="text" />

Finally, you'll need to correct the following line because it has an extra colon:

<%= observe_field(: :one_new_col,

change it to

<%= observe_field( :one_new_col,

Good luck,
