window.location.href使用open new tab而不使用Jquery中的window.open

Question

我需要立即使用Pay来打开新标签页 如果点击指示打开新标签页的支付键按钮。

$(function() {
  $("#OrderTable > tbody > tr > td> .paynow").click('click', function(Myevent) {


    Myevent.preventDefault();
    var urls = $(this).attr('href');
    var passval = $(this).parents().siblings('td:eq(1)').text();

    $.ajax({
      type: "POST",
      datatype: "json",
      async: true,
      url: '/MyAccount/PayNow?OrderId=' + passval,
      contentType: "application/json; charset=utf-8",
      success: function(RtObject) {
        //alert(RtObject.isError);
        //alert(RtObject.CId);
        if (!RtObject.isError) {
          //alert(RtObject.isError);
          if (RtObject.CId == 1) {
            var newwin;
            if (newwin && !newwin.closed) {
              newwin.focus();

            } else {
              window.location.href = RtObject.ReturnVal;




            }
          } else if (RtObject.CId == -1) {
            jAlert(RtObject.Message, "Failure");
          }
        }
      },
      failure: function(response) {
        jAlert("Cant go to payment process", "Failure");
      }
    });

  });

我需要打开新标签。请解决此问题。
