rails创建用于下载的按钮
原标题:rails create a button for downloading

I need to create a button for downloading So far I have create a button using this

<%= form_tag /myproject/download , :multipart => true, :onclick=>"document.getElementById( popup ).style.display= block ; return true;" %>
<%= submit_tag Download %> <% end %>

but I don"t know how to link the submit_tag with the link of downloading. (so as simple as if I press the button, then it will go to localhost/file and pop up a save to option) I am aware that I can use link_to, but I need to put a button that acts as a link_to

有人能指出如何在铁轨上做到这一点吗?非常感谢。

最佳回答

尝试button_to方法,该方法与link_to几乎相同

http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i按钮_

问题回答

你可以把一个链接放在上面,然后把它做成按钮的样式。或者你可以这样做有没有一种方法可以使用rails表单助手生成提交的按钮标记

请尝试使用按钮to方法。您可以查看文档
