如何判断 bootstrap 模式是否打开，以便我可以使用 jquery 验证

I need to make a validation only if a modal is open, because if I open it, and then I close it, and the I press the button that opens the modal it doesn't work because it is making the jquery validation, but not showing because the modal was dismissed.

So I want to ad a jquery if modal is open so the i do validate, is this possible?

<script>
$(document).ready(function(){

var validator =$('#form1').validate(
 {
  ignore: "",
  rules: {

usu_login: {
  required: true
},
usu_password: {
  required: true
},
usu_email: {
  required: true
},
usu_nombre1: {
  required: true
},
usu_apellido1: {
  required: true
},
usu_fecha_nac: {
  required: true
},
usu_cedula: {
  required: true
},
usu_telefono1: {
  required: true
},
rol_id: {
  required: true
},
dependencia_id: {
  required: true
},
  },

  highlight: function(element) {
$(element).closest('.grupo').addClass('has-error');
        if($(".tab-content").find("div.tab-pane.active:has(div.has-error)").length == 0)
        {
            $(".tab-content").find("div.tab-pane:hidden:has(div.has-error)").each(function(index, tab)
            {
                var id = $(tab).attr("id");
        
                $('a[href="#' + id + '"]').tab('show');
            });
        }
  },
  unhighlight: function(element) {
$(element).closest('.grupo').removeClass('has-error');
  }
 });

}); // end document.ready

</script>
