Hi all,
I am trying to call some javascript function defined in partial page "_results.html.erb". But it seemed that the js functions in the page are unrecognizable, and I have no idea why.
In my app, I have an "index" action/view containing an form_remote_tag sending the ajax request to a "process" action. After some calculation in the "process" action, it passes a local variable to a result page and renders it partially. Briefly, the index.html.erb looks like:
# index.html.erb <% form_remote_tag :url => 'process', :id => 'inputs', :update => {:success => 'result_div', :failure => 'document.write(request.responseText)'} do -%> # some input tags here <%= submit_tag "calculate" %> <% end -%> <div id = 'result_div'></div>
In controller#index, there is nothing. In controller#process, there is the calculation code which will cost several seconds, after that it is the render method:
def process # calculation code which will generate a result - @ruby_result - which is an ruby object render :partial => 'results', :locals => {:ruby_result => @ruby_result} end
And in _results.html.erb:
<a href = "javascript:showResult()">show result</a> <script type="text/javascript"> function showResult() { // code to show the result somewhere else on the index page // BUT I MUST use the <%=ruby_result%> variable here } </script>
The update of the result_div is totally ok, but when I click on the "show result", nothing happened. I tried putting the showResult() function in the index.html.erb. Then it can be found by the _results.html.erb. However the problem is that the ruby_result can only be got after the process. As a result, it's not accessible in the index view when it is initially loaded. How should I solve this problem?
I am not sure if I have expressed my question clearly. Any reply or comment is welcome.
Thanks!
