Question

我正在尝试使用ajax更新页面的特定部分，但js.erb文件似乎并没有替换我的div中的内容。我也注意到当地人因某种原因没有被传递给我的部分。在我的控制器中，我有一个加载show.html.erb的show动作，当单击一个项目时，它会发送一个ajax请求。这些项目位于具有id =＆＃34; stream-contents＆＃34;的div中。请求将发送到我的控制器中名为get_tree_folder的操作，响应格式为JS。 js.erb和部分文件与我的show.html.erb位于同一文件夹中。

这是我的控制器动作get_tree_foler：

def get_tree_folder
  @file_view = false;
  @curriculum = Curricula.find_by_id(params[:id])
  @git = get_bare_repo @curriculum
  @branch = params[:branch]
  tree = @git.gtree(params[:tree])
  @child_trees = tree.trees
  @child_blobs = tree.blobs

  respond_to do |format|
    format.js
  end
end

我的js.erb文件get_tree_folder.js.erb：

$('#stream-contents').html(<%= escape_javascript(render :partial => 'tree', :locals => { branch: @branch, child_trees: @child_trees, child_blobs: @child_blobs, curriculum: @curriculum }) %>);

控制台输出：

Started GET "/curricula/5/master/a9d280e6a0eb41ab7ea012f10f516913b2e53061" for 127.0.0.1 at 2014-03-27 13:52:36 -0700

非常感谢任何建议。

将参数包装在引号中的$('#stream-contents').html()：

$('#stream-contents').html("<%= escape_javascript(render :partial => 'tree', :locals => { branch: @branch, child_trees: @child_trees, child_blobs: @child_blobs, curriculum: @curriculum }) %>");

js.erb没有刷新页面轨道
