为什么在 YUI javascript 中生成的链接无法在 Rails 中呈现？

使用YAHOO.widget.treeview生成一个包含三个级别数据的表：模块、子模块和详细信息。如果存在与详细信息行关联的图像，则 JavaScript 会生成一个链接：

"<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>"

该链接将附加到该行的 html 中。

url 已正确生成并显示链接。单击时，除了浏览器状态栏中出现“完成”一词外，不会发生任何事情。

我从不使用 javascript 的另一个页面调用完全相同的 url，并且屏幕截图页面按预期显示。

这是控制器。

类 ScreenshotController <应用程序控制器
定义显示如果@detail.screen_path.length > 1 @imagePath = "#{RAILS_ROOT}" + “/private/#{Company.find(@detail.company_id).subdir}/” + "#{Project.find(@detail.project_id).subdir}/screenshot/" + “#{@detail.screen_path}” send_file (@imagePath, :type => 'image/jpeg', :disposition => 'inline') 结束
结尾示例

网址： http://localhost:3004/screenshot/show/20854

此代码来自属于详细模型作品的 show.html.erb：

View', :controller => 'screenshot', :id => @detail.id, :action => 'show' %>

有什么想法吗？？？

原文

Using YAHOO.widget.treeview to generate a table with three levels of data: module, submodule, and detail. If there is an image associated with a detail row the javascript generates a link:

"<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>"

that is appended to the html for the row.

The url is generated correctly and the link appears. When clicked nothing happens except the word 'Done' appears in the browser status bar.

Am calling the very same url from another page that does not use javascript and the screenshot page appears as expected.

Here is the controller.

class ScreenshotController < ApplicationController
def show
if @detail.screen_path.length > 1
@imagePath = "#{RAILS_ROOT}" +
"/private/#{Company.find(@detail.company_id).subdir}/" +
"#{Project.find(@detail.project_id).subdir}/screenshot/" +
"#{@detail.screen_path}"
send_file ( @imagePath, :type => 'image/jpeg', :disposition => 'inline')
end
end
end

A sample url: http://localhost:3004/screenshot/show/20854

This code from show.html.erb belonging to the detail model works:

View', :controller => 'screenshot', :id => @detail.id, :action => 'show' %>

Any ideas???
