partial-views

问题 I have a partial that I am using in different pages. I want to conditionally hide a certain div inside the partial based on the view that is rendering it. I was thinking about creating a page specific javascript file that would look up the div and and hide it. But, if there was a way to retrieve the view name / page name inside the partial it would be central to the partial and would not necessitate loading the same javascript file in multiple pages. Does anybody know a way to do this inside

问题 I want to have two partial views , one for SEARCH and one for SEARCHRESULTS . I want to update SEARCHRESULTS when the "Search" Button is clicked on the SEARCH partial view form.

问题 I just came across a blog that mentions a j function in Rails. They were using it to do ajax style page updates. $('#cart').html("<%=j render @cart %>"); I get they are using partials to render the cart partial, but whats the point of j ? I've found some articles that say it converts the string to something JavaScript will accept, but what does that mean? 回答1: escape_javascript(javascript) Escapes carriage returns and single and double quotes for JavaScript segments.

问题 In the past, whenever I wanted to update a part of my view through Ajax, I've done the following: create a partial out of the part I want to update and give it a unique ID, say #tracks create a special action in the controller for that Ajax call, say remove_track that updates all the values, etc. and add format.js create a new JS file with the same name as the action so Rails calls it automatically remove_track.js.erb which contains something like: $('#tracks').html("<%=j render 'cds/show

问题 I'm new to the MVC development so please bear with me. Is it really necessary to name my partial view like _Action.cshtml (with the _ underscore) to comply with the naming convention?

问题 Would someone confirm the best place for a partial view in ASP.NET MVC? My thinkings are if it's a global view that's going to be used in many places then SHARED. If it's part of a view that's been wrapped up into a partial view to make code reading easier, then it should go into the Views/Controller directory Am I correct or am I missing something? 回答1: I believe you are correct. Here is an example of something I do, general navigation partial views in my Shared directory. and then a partial

问题 I have a view for a controller called "show". Inside that view, i want to render the contents of another controller's view - and obviously, the logic for the form on that view to talk to the controller it belongs too. How do I do this? I am fairly new to rails and I'm not 100% confident with the framework yet. You could almost consider them "widgets" on the view. I know you can render actions from the same controller on the view by using: render :action => "show_home_page", :layout=> false
