是否可以将中的值<span>用作Ruby函数的参数？</span>

Question

I'm passing a span to an HTML file from a javascript file using:

$('#eventCode').html event.code

From said HTML file I'm displaying the contents of the selected code with:

<span id="eventCode"></span>

This works fine, but I also am trying to make a ruby function call as follows:

<%= link_to "Delete", Event.find_by_code("eventCode would go here"), 
    method: :delete, confirm: "Are you sure you want to delete the event?" %>

Is there any way I can take the contents of a HTML span and use them as a parameter for a Ruby function, as shown above?

Answer 1

Since your link_to tag is just a HTML <a> tag being rendered, you could pass your event.code directly to that tag ?

Uniquely identify your link with an id:

 <%= link_to "Delete", "Code name soon to be replaced", id: "eventCode-delete-link",  method: :delete, confirm: "Are you sure you want to delete the event?" %>

and do something like this with your JS:

$('#eventCode-delete-link').html event.code

Would that work for your use case ?

EDIT

On second thought, if you want to pass your code name directly into Event.find_by_code("codename") then you won't be able to. In that case, you should handle this in a controller ahead of calling this probably.
