jquery - jQuery-Steps OnFinishing 事件缺少 CurrentIndex 参数

Question

我正在使用jQuery 步骤，一切似乎都在工作，除了我想为所有步骤设置一个完成/保存按钮并执行不同的操作。尽管根据其文档， OnFinishing 事件将 currentIndex 作为其参数，但它看起来并没有被设置，并且当我调试代码时它总是未定义。我在设置中有什么遗漏吗？

 $("#wizard").steps({
        /* Appearance */
        bodyTag: "section",
        stepsOrientation: 1,//vertical            
        showFinishButtonAlways: true,

        /* Behaviour */
        enableAllSteps: true,
        saveState: true,

        /* Events */
        onStepChanging: function (event, currentIndex, newIndex) {                                              
           return true;
        },
        onStepChanged: function (event, currentIndex, priorIndex) { },
        onFinishing: function (event, currentIndex) {                
            console.log(currentIndex);                
        },
        onFinished: function (event, currentIndex) {
            console.log(currentIndex); 
        },

        /* Labels */
        labels: {
            current: "current step:",
            pagination: "Pagination",
            finish: "Save",
            next: "Next",
            previous: "Previous",
            loading: "Loading ..."
        }
    });
