Trigger Datatables search after reload

Question

I have a datatables table setup

Mainpage.php

new DataTable('.dataTable',{ "pageLength" : 100, scrollCollapse: true, scrollY: '500px', "bPaginate": false, columnDefs: [{ "defaultContent": "-", "targets": "_all" }] }); 

When a user does a thing, I reload the page. I would like the reloaded page to have the search filter activated after reload.

Here is the code on the page where a user does their thing.

 <script> $('body).on('//Some event),function(){ //get the search term var searchTerm = $('#dt-search-2').val(); //reload window.location.href = url+"?tab=licenses&search="+searchTerm; }); </script> 

On the MainPage.php

<script> //get the search term from the parameters in url var searchTerm = "<?php if (isset($_GET['search'])){ echo $_GET['search']; }?>"; //populate the search field in datatables $('#dt-search-2').val(searchTerm); //What can i use here to trigger the actual filter? </script> 

I have tried

 $('#dt-search-2').trigger('click'); $('#dt-search-2').focus(); 

Currently, I see the reloaded page and the value of the searchterm is populated in #dt-search-2, i just cant get the filter to actual go.
