Javascript Question
How to refresh the browser with JS after clicking a link_to tag in a Rails app
I'm trying to refresh the browser after the user clicks a link to an action that updates the database.
I want to avoid using redirect_back to prevent being sent back to the top of the screen after reload so I'm adding a JS click listener to the link_to tag with a code like this:
# in my view
<h5 class='my-link'><%= link_to 'vote', vote_path' %></h5>
# at the bottom of my application layout
<script>
$('.my-link').click(function (event) {
window.location.reload(true);
});
</script>
The JS code listener works OK in that if I click on any section of the h5 element the page will reload. However, when I click in the link the application will go to the relevant controller#action but the page wont reload.
I'm assuming I'm missing a way to execute first the link action and then force the refresh. So at click the app records a vote and then JS force a reload. Can you see any way I can achieve this? Thanks.
UPDATE
I some what solved this issue by adding a timer to the JS event so it gives time for the link to reach the controller and do the action and do the reload after it.
<script>
$(document).ready(function() {
$('.puke-icon, .clean-link, .comment-send').click(function() {
setTimeout(function(){
window.location.reload(true); },
50);
});
});
</script>
This is probably too hacky so hopefully you can provide more elegant approaches thanks!
Answer
In your vote controller action, use location.reload() in respond_to do format.
respond_to do |format|
format.js {render inline: "location.reload();" }
end
View:
<h5 class='my-link'><%= link_to 'vote', vote_path' %></h5>
Controller:
class VotesController < ApplicationController
def vote
----------------------
// your code goes here
----------------------
respond_to do |format|
format.js {render inline: "location.reload();" }
end
end
end
This will reload the page after the database action is completed.
