Question

我在网上找到了这条Jquery和HTML代码，创建了一个多步骤表单。但是，我希望能够操作代码，以便用户可以跳转到特定步骤。

例如：在表格的顶部，我提出了一个问题，即“你喜欢数学还是科学”。表单包含两个按钮，一个表示“数学”，另一个表示“科学”。目前，如果单击任一按钮，它将引导您进入表单的下一步。但是，我想这样做，如果用户点击“数学”，它将采用与用户点击“科学”时不同的形式。

以下是代码的外观，您可以看到演示@：http://thecodeplayer.com/walkthrough/jquery-multi-step-form-with-progress-bar

Answer 1

<强>供参考：

我给出了详细的答案。因此，请完整阅读答案并了解我在代码中所做的所有更改。

详细答案：

根据您的要求为每个fieldset提供标识。如下所示，

<fieldset id="firstField"> <!-- First Step -->
<fieldset id="mathsField"> <!-- Maths -->
<fieldset id="scienceField"> <!-- Science -->

您的js代码基于.next和.previous类正在运行。所以，我们应该用我们的逻辑来改变这种流动。您已经为按钮数学和科学分配了名称，如下所示，

<input type="button" name="maths" class="next action-button" value="Math" />
<input type="button" name="science" class="next action-button" value="Science" />

因此，在$(".next").click(function(){ });中，只需通过按钮name检查，如果点击的按钮是数学或科学，并将相应的fieldset DOM设置为变量{{1像下面的代码一样，

next_fs

并在if($(this).attr('name') == 'maths') next_fs = $('#mathsField'); if($(this).attr('name') == 'science') next_fs = $('#scienceField');将$(".previous").click(function(){ }); DOM设置为变量#firstField，如下面的代码所示，

previous_fs
