退回按钮以引导步骤

标签: javascript twitter-bootstrap jquery-steps

我正在我的网站上使用此步骤插件/代码: https://bootsnipp.com/fullscreen/RlOe3

我想要的是,当我在第二个或第三个选项卡上时,我想显示上一个div /步骤的后退按钮。

如果我将按钮添加为titanicH2oTree = h2o.getModelTree(model = titanic_1tree, tree_number = 1) ,该如何使用JavaScript?

class="backBtn"

下面有一个有效的示例。我使用了您提供的链接中的代码。我所做的是:

  • 添加了两个后退按钮=> <button class="btn btn-primary backBtn btn-lg pull-left" type="button" >Back</button>
  • 查看了next函数的实现方式并扭转了行为

当您按返回时,我也会禁用下一步。如果您还想清除这些值,则可以轻松完成in,但这就是您的作业。

干杯!

$(document).ready(function () {
  var navListItems = $('div.setup-panel div a'),
          allWells = $('.setup-content'),
          allNextBtn = $('.nextBtn'),
          allBackBtn = $('.backBtn');

  allWells.hide();

  navListItems.click(function (e) {
      e.preventDefault();
      var $target = $($(this).attr('href')),
              $item = $(this);

      if (!$item.hasClass('disabled')) {
          navListItems.removeClass('btn-primary').addClass('btn-default');
          $item.addClass('btn-primary');
          allWells.hide();
          $target.show();
          $target.find('input:eq(0)').focus();
      }
  });

  allNextBtn.click(function(){
      var curStep = $(this).closest(".setup-content"),
          curStepBtn = curStep.attr("id"),
          nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().next().children("a"),
          curInputs = curStep.find("input[type='text'],input[type='url']"),
          isValid = true;

      $(".form-group").removeClass("has-error");
      for(var i=0; i<curInputs.length; i++){
          if (!curInputs[i].validity.valid){
              isValid = false;
              $(curInputs[i]).closest(".form-group").addClass("has-error");
          }
      }

      if (isValid)
          nextStepWizard.removeAttr('disabled').trigger('click');

    var prevStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().prev().children("a");
    
    prevStepWizard.trigger('click');
    currStepWizard.attr("disabled", "disabled");
  });

  $('div.setup-panel div a.btn-primary').trigger('click');
