如何自定义jquery步骤向导

Question

我正在使用jquery-steps库在步骤向导中工作。但是问题是取消按钮将用户重定向到另一个部分，即使我选择了下一个按钮，该按钮仍继续生成。如何创建它，使其仅能显示在创建它的一个步骤中，而不必重新生成其他取消按钮，即使用户没有选择取消也是如此。这是我处理过的jQuery代码以及jsfiddle上的其余代码：

$(function() {

  let form = $('#wizard').show();

  form.steps({
    headerTag: "h2",
    bodyTag: "fieldset",
    transitionEffect: "fade",
    onStepChanging: function(event, currentIndex, newIndex) {

      switch (newIndex) {
        case 0:
          console.log("Verifying phone number");
          $('a[href$="#previous"]').html('⇽');
          $('a[href$="#next"]').html('⇾');
          var $input = $('<li aria-hidden="false" aria-disabled="false" class style="display: block;"><a href="#emailEnrollment" role="menuitem">&#10005;</a></li>');
          $input.appendTo($('ul[aria-label=Pagination]')).click(function() {
            window.location = "/enrollment/emailEnrollment";
          }).hide();

          break;
        case 1:
          console.log("Verifying code");
          $('a[href$="#previous"]').html('&#8701;');
          $('a[href$="#next"]').html('&#8702;');
          break;
        case 2:
          var $input = $('<li aria-hidden="false" aria-disabled="false" class style="display: block;"><a href="#emailEnrollment" role="menuitem">&#10005;</a></li>');
          $input.appendTo($('ul[aria-label=Pagination]')).click(function() {
            window.location = "/enrollment/emailEnrollment";
          });

          $('a[href$="#previous"]').html('&#8701;');
          $('a[href$="#next"]').html('&#10003;');
          break;
        default:
          $('a[href$="#previous"]').html('&#8701;');
          $('a[href$="#next"]').html('&#8702;');
          console.log("Add source of funds");
          break;
      }



      if (currentIndex < newIndex) {
        // To remove error styles
        form.find(".body:eq(" + newIndex + ") label.error").remove();
        form.find(".body:eq(" + newIndex + ") .error").removeClass("error");
      }

      // form.validate().settings.ignore = ":disabled, :hidden";
      // return form.valid();
      return true;
    },
    labels: {
      finish: "Submit",
      next: "&#8702;",
      previous: "&#8701;",
      cancel: "No"
    }
  }).validate({
    rule: {
      phone: 'required',
      code: 'required'
    }
  });
