Question

I’m Implementing Ajax with Rails by adding a new post in runtime without refreshing the page.
The problem is I want to render a specific view by this script which is allocated in create.js.erb

 $('<%=render(:file => "posts/post.html.erb)%>').insertBefore($('.posts').children('div.post-box').first());

But it doesn’t work, Can anyone tell me what’s wrong on this script and how to select html code in jquery from a specific view?

and this’s the create action

def create
  @post = Post.new(params[:post])
  respond_to do |format|
    if @post.save
      format.html { redirect_to :back, notice: 'Post was successfully created.' }
      format.js             
    end
end

Answer 1

All you need is add escape_javascript method, just like this

$('<%= escape_javascript(render(:file => "posts/post.html.erb"))%>').insertBefore($('.posts').children('div.post-box').first());
