How to assign an ID to the global search box using datatable.net

If you want to assign an id on focus.

$(document).ready( function () {
  var table = $('#dt').DataTable(); // Initialize DataTable on #dt
  
  // Listen for focus on search input
  $('#dt_filter label input').on( 'focus', function () {
    this.setAttribute( 'id', 'search' ); // Set the id attribute to 'search'
  });
} );

The $(document).ready() ensures the code runs after the document has fully loaded.

When the global search input (#dt_filter label input) receives focus (the user clicks or tab-focuses it), an event listener (.on('focus')) is triggered.

The setAttribute('id', 'search') method sets the id of the search input to search when it gains focus.

If you want to assign id when data is finished loading.

initComplete : function() {
       $("#dt_filter input").prop( 'id', 'search_box' );// Set the ID of the search input after data loads
  },

Inside this callback, it selects the search input field (#dt_filter input) and assigns it the id of 'search_box' using the .prop() method.

The initComplete function is executed once the DataTable has finished its initialization and the data is fully loaded.
