从js函数调用引导程序模式

Question

I have a JavaScript function that does a data validation, the problem is using alerts to warn when data is wrong. What I want to do is show Bootstrap modal windows to see the error. This is what I did, it does not work. var contador = somevalue; window.validar = function (cual){ if(cual.value == -1){

    }
    if($("#muestragrafico1").is(':checked')){
        var cantidad = 3;
    }else{
        var cantidad = 1;
    }
    if(cual.checked){
        contador++;
    }else{
        contador--;
    }
    if(contador <= cantidad){
        return true;
    }else{
        if (cantidad == 3) {
            //alert("Solo puede seleccionar un máximo de "+cantidad+" sensores.");
            $('#myModalExito').modal('show');

        }

        if (cantidad == 1) {
            alert("Solo puede seleccionar un máximo de "+cantidad+" sensores.");
        }
        contador--;
        return false;
    }
}` 

  <!-- Modal content-->
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">&times;</button>
      <h4 class="modal-title"><?php echo L::Ticket_Succes?></h4> </div>
  </div>

</div>

You can show error dynamically as below.

Reference to create modal dynamically is here .

 function showError(message, type) { BootstrapDialog.show({ title: (type == 1 ? 'Warning' : 'Error') + ' message', message: message, buttons: [{ label: 'Close', cssClass: (type == 1 ? 'btn btn-warning' : 'btn btn-danger'), action: function(dialog) { dialog.close(); } }] }); } function validationFunction(i){ if(i==0) { showError('This is error without type'); return false; } else if(i==1) { showError('This is error with type id 0 (Error)(Default)',0); return false; } else if(i==2) { showError('This is error with type id 1 (Warning)',1); return false; } }
