Rails 的 link_to_function 弃用状态? [英] Status of Rails' link_to_function deprecation?

问题描述

Rails 中 link_to_function Javascript 助手的状态是什么?我在this stackoverflow question中读到，这是在 Rails 3.0 中弃用，然后不推荐使用，然后在 3.2.4 中再次弃用.这是我可以依赖并教给学生的东西吗?我刚刚阅读了 发布Rails 3.2.8 的注释(来自搜索):

What is the status of the link_to_function Javascript helper in Rails? I read, including in this stackoverflow question, that it was deprecated in Rails 3.0, then undeprecated, then deprecated again in 3.2.4. Is it something I can depend on and teach students? I just read the release notes (from a search) for Rails 3.2.8:

恢复了 button_to_function 和 link_to_function 助手的弃用.拉斐尔·门东萨·弗兰萨

Reverted the deprecation of button_to_function and link_to_function helpers. Rafael Mendonça França

现在情况如何?

推荐答案

link_to_function 在 3-2-stable 分支和将来它不会在 3-2-stable 中被弃用.但是它IS 在当前的 master 分支中被弃用，并且在 Rails 4.0 发布时将被弃用.所以我想它会从 4.1 中的 rails 代码中删除.所以你可以教学生这样做(来自 rails 4 更新日志):

link_to_function is NOT deprecated in 3-2-stable branch and it won't be deprecated in 3-2-stable in future. But it IS depreacated in current master branch and will be deprecated in Rails 4.0 when it releases. So I guess it will removed from rails code in 4.1. So you can teach students to do this (from the rails 4 changelog):

我们建议改用 Unobtrusive JavaScript.例如:

We recommend the use of Unobtrusive JavaScript instead. For example:

link_to "Greeting", "#", class: "nav_link"

$(function() {
  $('.nav_link').click(function() {
    // Some complex code

    return false;
  });
});

或

link_to "Greeting", '#', onclick: "alert('Hello world!'); return false", class: "nav_link"
