javascript - How to auto-refresh a div -


i have controller , view div : 

def show   @requests = events.get_requests end

get_requests returns requests in database select, output in div in view:

<div class="party-block" id="requests">   <h4><%= t '.requests' %></h4>   <input type="button" value="<%= t '.refresh' %>" onclick="window.location.reload()" class="btn-sm btn-info">   <% @requests.each |r| %>     <span class="request">       ...

in div print requests other things.

i want automatically refresh div javascript/jquery function. moment use button refresh need re-execute code in controller?

there function in javascript named setinterval lets schedule function executed every time interval.

setinterval(function() {    console.log("hi there");   }, 1000);
