Question

您好我有以下HTML结构：

<div class="form-step2 hidden"></div>
<div class="form-step2 hidden"></div>
<div class="form-step2 hidden"></div>
<div class="form-step2 hidden"></div>
<button type="button" id="addblock" class="btn btn-primary btn-block">+</button>

如果我点击按钮，我想删除一个隐藏的，而不是下一个隐藏的。我的JS：

$( "#addblock" ).click(function() {
$( ".form-step2" ).next(".form-step2").removeClass("hidden");
});

但这会删除所有隐藏的

Answer 1

使用类form-step2

从第一个hidden元素中删除隐藏的类

$("#addblock").click(function() {
  $(".form-step2.hidden:first").removeClass("hidden");
});

.hidden {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="form-step2 hidden">1</div>
<div class="form-step2 hidden">2</div>
<div class="form-step2 hidden">3</div>
<div class="form-step2 hidden">4</div>
<button type="button" id="addblock" class="btn btn-primary btn-block">+</button>

Answer 2

$("#addblock").click(function() {
  $('.hidden:first').removeClass("hidden");
});

.hidden {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<div class="form-step2 hidden">A</div>
<div class="form-step2 hidden">B</div>
<div class="form-step2 hidden">C</div>
<div class="form-step2 hidden">D</div>
<button type="button" id="addblock" class="btn btn-primary btn-block">+</button>

试试这个：

$( "#addblock" ).click(function() {
    var $step = $( ".form-step2" ).not('.hidden');
    if($step.length<1)
    {
       $( ".form-step2:first" ).removeClass("hidden");
     }
     else
    {
      $step.next(".hidden").removeClass("hidden");
    }

});
