如何在Ruby on Rails 3.2.8上将数据保存在LocalStorage上？ [英] How do I save data on LocalStorage in Ruby on Rails 3.2.8?

问题描述

我试图保存一个名为 persistent_data 的变量。

I'm trying to save a variable called persistent_data.

我通常使用 session [：persistent_data] 或 cookies [：persistent_data] ，但我想使用localstorage。

I usually use session[:persistent_data] or cookies[:persistent_data], but I would like to use the localstorage instead.

我如何在Rails上执行此操作？

推荐答案

Localstorage与rails无关。您可以像使用任何其他语言一样进行操作：

Localstorage has nothing to do with rails. You do it the same way as with any other language:

<script>
localStorage.setItem("company_id", "1");
</script>

localStorage.getItem("company_id");
=> 1

您可以使用rails来动态设置该项目：

You can use rails to dynamically set the item however:

<script>
localStorage.setItem("company_id", "<%= @company.id %>");
</script>
