How to display multiple errors in different sections by defining the error function once to optimize our code

We can display multiple errors in different sections by just defining the error function once to optimize the code.

events: _.extend(OrderWizardModuleAddress.prototype.events, {
          'click [data-action="select"]': "selectAddress",
        }),
        // function to send the error details to the showMessage function
        showError: function (message, type, container) {
          this.showMessage(message, type, container);
        },
        // function to display the error
        showMessage: function (message, type, container) {
          var global_view_message = new GlobalViewsMessageView({
            message: message,
            type: type,
            closable: true,
          });
          jQuery(container).show();
          var msgContainerParent = jQuery(container);
          msgContainerParent.html(global_view_message.render().$el.html());
        },
        //this code is to check the po box is there or not in the address//
        selectAddress: function (e) {
          let self = this;
          jQuery(".wizard-content .alert-error").hide();
          let selectedAddr1 = this.addresses._byId[jQuery(e.target).data("id").toString()].attributes.addr1;
          let poBoxPattern = /^ *((#\d+)|((box|bin)[-. \/\\]?\d+)|(.*p[ \.]? ?(o|0)[-. \/\\]? *-?((box|bin)|b|(#|n|num|number)?\d+))|(p(ost|ostal)? *(o(ff(ice)?)?)? *((box|bin)|b)? *(#|n|num|number)*\d+)|(p *-?\/?(o)? *-?box)|post office box|((box|bin)|b) *(#|n|num|number)? *\d+|(#|n|num|number) *\d+)/i;
          if ( this.$el[0].attributes[0].value.indexOf( "OrderWizard.Module.Address.Shipping" ) > -1) {
            if (poBoxPattern.test(selectedAddr1)) {
              self.showError('You cannot select a PO Box address as Shipping Address', 'error', '.order-wizard-shipmethod-module-message-error');
              this.error = null;
              $("html, body").animate({
                scrollTop: $('.order-wizard-shipmethod-module-message-error').offset().top - 70}, 10);
            } else {
              this.setAddress(jQuery(e.target).data("id").toString());
              this.render();
              this.trigger("ready", true);
            }
          } else {
            this.setAddress(jQuery(e.target).data("id").toString());
            this.render();
            this.trigger("ready", true);
          }
        },
