Question

我正在尝试将值user.skypeid传递给html.erb中的javascript代码participants。做正确的方法是什么？以下方法对我不起作用。

  <% @users.each do |user| %>
<tr>
  <td><%= user.name %></td>
  <td><%= user.skypeid %></td>
  <td><%= link_to 'Show', user_path(user) %></td>
  <td>
    <div id="SkypeButton_Call_aaa_1">
     <script type="text/javascript">
     Skype.ui({
     "name": "call",
     "element": "SkypeButton_Call_aaa_1",
     "participants": [user.skypeid]
     });
     </script>
    </div>
  </td>
</tr>

您必须将其打印为嵌入式红宝石，并将其包装在引号内：

plot_glaciers <- function(keep_glaciers = TRUE) {
  layers <- vector('list')

  layers$land    <- geom_point(data = ds1, aes(x = Sepal.Length, y = Sepal.Width), color = "red")
  layers$def     <- list(scale_x_continuous("Longitude", breaks = seq(3, 8, by = 0.5)),
                    scale_y_continuous("Latitude", breaks = seq(1,5, by = 1)),
                    theme_bw())

  if (keep_glaciers) {
    layers$glacier <- geom_point(data = ds2, aes(x = Sepal.Length, y = Sepal.Width), color = "blue")
  } 

  ggplot() + layers
}

plot_glaciers(TRUE)
plot_glaciers(FALSE)

虽然您可以将脚本移到外面或移动到另一个文件：

<% @users.each do |user| %>
  <tr>
    <td><%= user.name %></td>
    <td><%= user.skypeid %></td>
    <td><%= link_to 'Show', user_path(user) %></td>
    <td>
      <div id="SkypeButton_Call_aaa_1">
      <script type="text/javascript">
        Skype.ui({
          "name": "call",
          "element": "SkypeButton_Call_aaa_1",
          "participants": ['<%= user.skypeid %>']
        });
       </script>
      </div>
    </td>
  </tr>
<% end %>
