嵌套的jQuery步骤 – Main Next上没有显示任何内容

前端之家收集整理的这篇文章主要介绍了嵌套的jQuery步骤 – Main Next上没有显示任何内容前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我有一个简单的html表单,嵌套jQuery步骤.

主向导有5个步骤,第3步有一个包含3个步骤的子向导.

单击主向导的“下一步”时,移动步骤并显示内容,但在第3步(具有子向导的步骤)之后,选项卡移动到4rth但是在达到4rth步时没有显示内容,如果我禁用了显示子向导的jQuery脚本,主要的4rth步骤显示内容.

我尝试了各种论坛,并开始调试jQuery Steps库一段时间,但无法找出原因.

任何帮助表示赞赏.

这是可执行的代码.

$("#frmMainWizard").steps({
      headerTag: "h3",bodyTag: "section",transitionEffect: "slide",// "fade",stepsOrientation: "vertical"
        //enableAllSteps: true,//enablePagination: false,});

    var childForms = $(".frmWizardSteps");
    $.each(childForms,function() {
      console.log(this.id);
      var currentSubStesId = '#' + this.id;
      $(currentSubStesId).steps({
        headerTag: "h4",bodyTag: "div",transitionEffect: "slideLeft",stepsOrientation: "vertical"
          //autoFocus: true,//enableAllSteps: true,//enablePagination: false
      });

    });

    $('#btnPrev').click(function() {
      $("#frmMainWizard").steps('prevIoUs');
    });

    $('#btnNext').click(function() {
      $("#frmMainWizard").steps('next');
    });

解决方法

试试我根据@medievo在 this post建议的解决方案制作的 JSfiddle working sample.

显然,问题是初始化和显示子向导后,不再调用主向导的onStepChange事件处理程序.调试库后,我可能会提供其他信息.会让你更新.

关于解决方案:

假设我们有两个函数可以使用jquery.steps库初始化主向导和子向导.

主向导的功能如下所示:

var shoMainWizard = function(){

    $("#main-wizard").steps({
        /* 
        All your jquery.steps config stuff here
        plus the following event handlers
        */

        onStepChanging: function (event,currStepIndex,nextStepIndex) {

            // If we are moving on the step which contains the sub-wizard (index 2)
            if (nextStepIndex == 2){ 
                shoSubWizard(currStepIndex,nextStepIndex);
            }

            return true;
        },onStepChanged: function (event,priorStepIndex) {
            $("#main-wizard-p-" + priorStepIndex).hide();
            $("#main-wizard-p-" + currStepIndex).fadeIn();
        }
    });
};

请注意,onStepChanging处理程序使子向导初始化并在第一次调用显示,并且只显示在下一次调用中.

另请注意,onStepChanged处理程序通过隐藏上一步视图来切换视图并显示下一步视图.

子向导的功能如下所示:

var shoSubWizard = function(currStepIndex,nextStepIndex){

    // if sub-wizard note rendered yet
    if (!$('#sub-wizard').hasClass('wizard')){

            /* 
            All your jquery.steps config stuff here
            plus the following event handlers
            */

            onFinished: function() {
                $("#main-wizard").steps("next");
            }
        });
    }
    // otherwise,display sub-wizard with last changes
    else { 
        $("#main-wizard-p-" + currStepIndex).hide();
        $("#main-wizard-p-" + nextStepIndex).fadeIn();
    }
}

请注意,有一个if语句通过询问是否已经有jquery.steps添加的向导类来确定子向导是否已经初始化.如果它已经初始化,我们只需要显示()它.

另请注意,onFinished处理程序使主向导继续执行下一步.

希望这有助于解决您的问题.

编辑:

在查看和调试代码之后,问题是以下jQuery查询(来自库的第1196行)从主向导和子向导获取所有步骤内容并进行转换(从包含子向导的步骤到下一步)步骤)搞砸了.

var stepContents = wizard.find(".content > .body")

通过以下方式更改该行可以解决问题.但是,还有一些其他行需要类似的修复.

var stepContents = wizard.find("> .content > .body")

另请注意,有一个待批准的pull request明显解决了这个问题.但是,恕我直言,拉请求直接从库中更改了构建的文件,它可能不会被批准.
