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

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
