我如何使用 jquery 呈现部分？

Question

I try to add AJAX to my blog. And i want to make post, edit and delete comments using ajax. For example, to post a comment, I used:

$(".comment<%=@comment.parent_id %>").append('<%= j render partial:'comments/comment', locals: {comment: @comment} %>');

But due to the fact that I have nesting, it was not displayed as I would like. All comments I have are in _comment.html.erb. Can I render a partial without reloading the page using jquery? And is this the right approach?

Answer 1

As I already wrote, all the comments I had were in the partial. And because of the nesting, I could not just add a new comment using the append function. Therefore, I just update the partial on the page, without reloading the page as follows:

$(".comments").replaceWith("<div class='comments'><%= j nested_comments @post.comments.arrange(order: :created_at)%>")
