javascript - Link_to 标签显示 map 模态 Rails 5

Question

当我点击 map 标记时，会弹出一个模式:

我刚刚实现了一个搜索功能，并试图在我点击一个结果时获得它，一个包含所有信息的模式将弹出，就像照片中一样。

这是我为该页面使用的代码:

map Controller :

class MapsController < ApplicationController
  def index

      @maps = Map.all
      @hash = Gmaps4rails.build_markers(@maps) do |map, marker|
      marker.lat map.latitude
      marker.lng map.longitude
       marker.json({:id => map.id,
            :number => map.number,
            :name => map.name,
            :tabid => map.tabid,
            :zipcode => map.zipcode,
            :latitude => map.latitude,
            :longitude => map.longitude
                  })     

    end
  end

  def favorite 
    @map = Map.new(:number => 'Favorite Site')
    @map.save
    redirect_to :back
    flash[:success] = "favorited"
  end



  def show
   @maps = Map.find(params[:id])

end
end

搜索 Controller :

class SearchController < ApplicationController
  def index
    if params[:query].present?
     @maps = Map.search(params[:query]).with_pg_search_highlight
     @count = @maps.pluck(:id).count


     @hash = Gmaps4rails.build_markers(@maps) do |map, marker|
      marker.lat map.latitude
      marker.lng map.longitude
       marker.json({:id => map.id,
            :number => map.number,
            :name => map.name,
            :tabid => map.tabid,
            :zipcode => map.zipcode,
            :latitude => map.latitude,
            :longitude => map.longitude
                  })         



      # marker.infowindow render_to_string(:partial => "/maps/info", :locals => { :object => map})
       end
    else 
      @maps = Map.all
  end
end
end

这是我的搜索结果页面代码:

现在，当我点击一个链接时，我会被重定向到 map ID 为空的链接(参见地址)，例如:

如果有人能指导我，将不胜感激。

更新 1

当我使用系统给出的建议答案时，我确实会看到一个模式弹出窗口。目标是让模态给我提供与我点击 map 标记相同的信息(见第一张图片)。当我最初点击搜索结果编号时，我得到以下信息:

但是，当我点击一个 map 标记时，当我点击结果链接时，它的模态弹出，每个弹出的模态将显示最后弹出的 map 标记模态的信息，这意味着模态看起来正确，如第一张图片对于搜索结果中的每个链接都是相同的模态。

更新 2

我认为我的问题是，这些链接不是 map 标记，因此编写的 javascript 不适用于它们。我怎样才能使链接与 map 标记的行为相同，以便将信息传输到模式。

更新 3

我正在尝试按照建议将函数拉出并单击以调用它，到目前为止我有这个并且它不起作用或我。

<%= link_to map.number, "#", data: {toggle: "modal", target: "#myModal"}, :html => {:onclick => 'initialize()' } %>

Answer 1

目前你的链接是这样的:

<%= link_to map.number, controller: "maps", action: "show", id: map.id %>

这是创建指向您的/maps/{id} url 的基本链接。

要打开带有链接的引导模式，请执行以下操作:

<%= link_to map.number, "#", data: {toggle: "modal", target: "#myModal"} %>

---

更新:

首先，您的 initialize函数已经用 $('#myModal').modal('show') 显示模态这样你就可以去掉 data: {toggle: "modal", target: "#myModal"}来自链接。

接下来，您的 initialize函数需要将特定的 map 标记元素传递给它，所以我建议这样做:

<%= link_to map.number, "#", class: "map-marker-link", data: {elem: map} %>

然后在你的 javascript 中:

$(".map-marker-link").click(function (event) {
    initialize($(this).data('elem'));
    event.preventDefault();
});
