使用Rails和jQuery动态呈现部分视图

In my app, I have a user profile page that has three tabs and a blank div below it. There is a default tab that is white and two other tabs that are darker and "unselected".

在我的应用程序中,我有一个用户配置文件页面,其中有三个选项卡,下面有一个空白div。有一个默认选项卡是白色,另外两个选项卡更暗,“未选中”。

I want to make it so that the content in the div below renders a partial based on which tab is selected.

我想这样做,以便下面div中的内容根据选择的选项卡呈现部分内容。

I already have it working to the point where jQuery allows me to click on the different tabs and it changes the colors of the tabs without a page refresh.

我已经让它工作到jQuery允许我点击不同的选项卡,它更改选项卡的颜色而不刷新页面。

However, I am stuck on how to get the partial to render correctly. Any thoughts on this? I am stuck on how to dynamically call a partial based on which tab is selected in the jQuery and actually am not sure if I need another file to interact with this to make it work. I am relatively new to jQuery in a rails app so I am not sure if I've done everything I need to.

但是,我坚持如何让部分正确渲染。有什么想法吗?我坚持如何动态调用部分基于jQuery中选择的选项卡,实际上我不确定是否需要另一个文件与此交互以使其工作。我在rails应用程序中对jQuery相对较新,所以我不确定我是否已经完成了我需要做的一切。

User profile page: app > views > show.html.erb

用户个人资料页面:app> views> show.html.erb

   <ul class="profile-tabs">    

        <%= link_to "<li class=\"tab selected\">Tab 1</li>".html_safe, userprofile_users_path, remote: true %>
        <%= link_to "<li class=\"tab\">Tab 2</li>".html_safe, userprofile_users_path, remote: true %>
        <%= link_to "<li class=\"tab\">Tab 3</li>".html_safe, userprofile_users_path, remote: true %>

    </ul>

<div id="profile-content">

<!--content goes here -->

</div>

jQuery: app > assets > javascripts > userprofile.js

jQuery:app> assets> javascripts> userprofile.js

$(function() {
        $("li.tab").click(function(e) {
          e.preventDefault();
          $("li.tab").removeClass("selected");
          $(this).addClass("selected");
          $("#profile-content").html("<%= escape_javascript(render partial: 
"How can I make this partial name be generated based on the value of the selected li?")%>");
        });
    });

Users Controller: app > controllers > users_controller.rb

用户控制器:app> controllers> users_controller.rb

class UsersController < ApplicationController

def show
    @user = User.find(params[:id])
end

def userprofile
    respond_to do |format|
        format.js
    end
end
end

There are three partials corresponding to the three tabs, and I need the jQuery to somehow dynamically change the partial being called based on the selected tab.

有三个部分对应于三个选项卡,我需要jQuery以某种方式动态更改基于所选选项卡调用的部分。

I'd really appreciate some help with this, or if there is another resource that can answer my question. I have not been able to find anything that directly answers what I am trying to do.

我真的很感激这方面的帮助,或者是否有其他资源可以回答我的问题。我找不到任何直接回答我想要做的事情。

Update ------

I used the solution provided rails_has_elegance but nothing is appearing in the div I am targeting. However, I am seeing this in the rails server output, which seems like it is doing what I want:

我使用了rails_has_elegance提供的解决方案,但我所针对的div中没有出现任何内容。但是,我在rails服务器输出中看到了这一点,看起来它正在做我想要的:

2 个解决方案

#1

If you want to avoid a lot of parameters, just make 3 different actions in your controller, one for each tab, which each respond to js. Then create a [action].js.erb for each action in the views with something like this:

如果你想避免很多参数,只需在你的控制器中做3个不同的动作,每个动作一个,每个动作都响应js。然后为视图中的每个操作创建一个[action] .js.erb,如下所示:

$("#tab_content").html("<%= escape_javascript(render('tab1')) %>");

You actually need to communicate with the server through a ajax request, whereas your onclick function would preload that partial and you don't have anything remote anymore.

您实际上需要通过ajax请求与服务器通信,而您的onclick函数将预加载该部分并且您不再具有任何远程服务。

#2

write an action in a controller having three conditions for 3 different tabs. call ajax by clicking on any tab, pass identity parameter say 'tab1' or 'tab2' or 'tab3' and also required parameters if you need. in controller, get parameters and call model function which contains actual business logic.

在具有3个不同选项卡的三个条件的控制器中写入操作。通过单击任何选项卡调用ajax,传递标识参数说'tab1'或'tab2'或'tab3',如果需要,还需要参数。在控制器中,获取包含实际业务逻辑的参数和调用模型函数。

get result in a controller and just render partial in a div below all 3 tabs using js.erb

在控制器中获取结果,然后使用js.erb在所有3个选项卡下面的div中渲染部分

#1

$("#tab_content").html("<%= escape_javascript(render('tab1')) %>");
