intermingle RJS partial rendering and raw javascript
wrap partial rendering in javascript
What I need is the ability to seamlessly send the contents of a partial to the client using the convenience of RJS, but wrapped inside a hand-written javascript condition (if some element exists, then update an element with this partial).
# RJS template page << "if ('some_element_exists') {// page.replace_html using a partial}"
The challenge is to interlace a basic javascript condition with the ActionView::Helpers::PrototypeHelper::JavaScriptGenerator::GeneratorMethods such as replace_html, hide, show, select, etc.
Viewing the source for replace_html, you see that it simply wraps the call GeneratorMethod, passing it Element.update, which is the prototype js function doing the client-side work. Additionally, it calls render to pull the html from the partial, which is exactly what I need. Thus, I now have exactly what I need to intermingle my javascript condition with the simplicity of RJS methods calls.
# RJS template page << "if ($('element_id')) { $('element_id').update(#{render :partial => 'my_partial_marshal'})};"
Notice that I remove replace_html for its javascript counterpart, Element.update. What's left is primarily raw javascript being appended to the page object but with the convenience of Rails' partial rendering.
