When we use the alert several times open a checkbox where the user has the option to disable the alert, is there any way to disable this feature? ( Never checkbox )

This behavior is by the browser rather than the JavaScript itself. It works as if it were a browser security tool, so disabling it (if possible) has to be done in the browser settings. In the case of a site already in production, it would hardly be possible to block this type of message for all users.

If you are using this to debug, use console.log ().

You can combine JavaScript, HTML, and CSS to display much more beautiful and sophisticated alerts (for example, modal windows) than the browser's default%.

The browser has no control over these custom alerts and does not give the user the option to block them.

One library you can use for this is VEX . You can see it running by running the code example below: 

vex.defaultOptions.className = 'vex-theme-os';

function mostreFeedback(mensagem) {
  jQuery("#feedback").attr('value', mensagem);
}

function confirmacao() {
  vex.dialog.confirm({
    message: 'Você tem certeza que deseja fazer isso?',
    callback: function(resultado) {
      if (resultado) {
        mostreFeedback("Ação confirmada com sucesso");
      } else {
        mostreFeedback("Ação cancelada");
      }
    }
  });

}
