无法选择link_to标记作为jquery选择器Rails [英] Can't select link_to tag as jquery selector Rails

问题描述

我是初学者Rails开发人员.我得到了带有"comments_link"类的link_to标记

I am a beginner rails dev. I got this link_to tag with the class of "comments_link"

%h2= link_to pluralize(@recipe.comments.count, "Comment"), "#", class: "comments_link , btn btn-success"

现在，在我写的 application.js 中

$(document).ready(function(){
  $(".comments_link").click(function(){
    $(".section").toggle();
  });                               
})

此代码的问题，无论我为click事件选择什么元素，它都有效.但是当我使用.comments_link类时，它不起作用.为什么会这样呢?

The problem with this code, whatever element i choose for click event, it works. But when i use .comments_link class, it doesn't work. Why is this happening?

除link_to标记外的所有内容均可用作事件侦听器.我需要添加一些代码吗?

Anything but link_to tags work as event listener. Do i need to add some sort of code to it?

顺便说一句，我只是做了相反的尝试，但还是奏​​效了.当我单击该部分时，它会切换链接.但是链接不能是事件侦听器.

Btw i did the reverse just to try and it worked. When i click on the section, it toggles the link. But the link cant be event listener.

$(document).ready(function(){
  $(".section").click(function(){
    $(".comments_link").toggle();
  });                               
}); <-- this one worked. I cant use ".comments_link" as event listener.

推荐答案

您在类名中有一个逗号，我认为这会使该类名无效.检查开发人员工具以检查元素以查看.comment_link是否实际存在.如果不是，请删除逗号，然后重试

You have a comma in the class name which I assume would invalidate the class name. Check developer tools in order to inspect the element to see if .comment_link actually exists. If not, remove the comma and try again
