抱歉, 我有一个铁路新问题 。 在我的铁路应用程序中, 我如何从视图中调用我的控制器定义的方法? 例如, 可以说我写了一种自定义的方法来检索股票信息 。 在我看来, 我想有一个普通的 HTML 按钮, 点击时, 它将调用我的自定义方法, 并填充股票结果 。
我到处找找都找不到直截了当的方法,但我肯定漏掉了一些东西。
“em% 强” 编辑 : 我按标题来回答问题, 不是问题是什么。 您问题标题的答案在底部 。
您想要的是一个 ajax 请求, 这是一个单独的控制器动作。 您需要 :
请求路径并按下按钮时弹出其 DOM 对象的 java 描述
返回 ajax 要求的任何动作
有很多方法可以做到这一点, 但如果你寻找“ 如何修铁路 ajax ”, 您将会找到帮助您前进的“ gazillion 教程 ” 。 我喜欢的一种方式是叫做 pjax : < a href=" https:// github. com/rails/ pjax_rails > https://github. com/rails/ pjax_rails
声明helfer_method ,类似:
在控制器中:
private
def find_stock
...
end
helper_method :find_stock
你们认为:
<% find_stock.each do |stock| -%>
文献资料:
这是一种方法,当然, 你可以使用远程选项 通过 AJAX 请求来做到这一点。
