javascript - 在 Accordion 上旋转单个人字形

Question

当您单击相应的标题时，我希望一个人字形旋转。截至目前，所有人字形都在旋转。我想我必须指定哪个 V 形，但我不知道如何指定。我在 ASP.NET MVC 5 中工作，我正在使用 razor View 通过列表进行 foreach。

Index

@{
    foreach (var item in Model)
    {
        <div class="accordion">
            <a href="#"><h4>@item.Title</h4><i class="fa fa-chevron-right rotate"></i></a>
        </div>
        <div class="accordion-desc">
            <h3>@Resource.AccordionProjectLead</h3>
            <h4>Kay Wiberg</h4>
            <h3>@Resource.AccordionDescription</h3>
            <p>
            @item.Description
            <p> 
            <div class ="link">
                <a href="@item.Url">@Resource.AccordionGoTo</a>
            </div>
        </div>
    }
}

CSS for the rotating chevron

.rotate {
  -moz-transition: all 0.1s linear;
  -webkit-transition: all 0.1s linear;
  transition: all 0.1s linear;
}

.rotate.down {
  -moz-transform: rotate(90deg);
  -webkit-transform: rotate(90deg);
  transform: rotate(90deg);
}

JS for accordion and chevron

$(document).ready(function() {
  $(".accordion-desc").fadeOut(0);
  $(".accordion").click(function() {
    $(".accordion-desc").not($(this).next()).slideUp('fast');
    $(this).next().slideToggle(400);
  });
});

$(".accordion").click(function() {
  $(".rotate").toggleClass("down");
});

from the browser:

<div class="container">
  <div class="accordion">
    <a href="#">
      <h4>Test Site</h4><i class="fa fa-chevron-right rotate down"></i></a>
  </div>
  <div class="accordion-desc" style="display: none;">
    <h3>Projektledare</h3>
    <h4>Kay Wiberg</h4>
    <h3>Beskrivning</h3>
    <p>

    </p>      
    <div class="link">
      <a href="">Gå till</a>
    </div>
  </div>
  <div class="accordion">
    <a href="#">
      <h4>Test site 2</h4><i class="fa fa-chevron-right rotate"></i></a>
  </div>
  <div class="accordion-desc" style="display: none;">
    <h3>Projektledare</h3>
    <h4>Kay Wiberg</h4>
    <h3>Beskrivning</h3>
    <p>

    </p>
    <div class="link">
      <a href="">Gå till</a>
    </div>
  </div>

</div>

$(document).ready(function() {
  $(".accordion-desc").fadeOut(0);
  $(".accordion").click(function() {
    $(".accordion-desc").not($(this).next()).slideUp('fast');
    $(this).next().slideToggle(400);
  });
});

$(".accordion").click(function() {
  $(".accordion").not(this).find(".rotate").removeClass("down");
  $(this).find(".rotate").toggleClass("down");
});

.rotate {
  -moz-transition: all 0.1s linear;
  -webkit-transition: all 0.1s linear;
  transition: all 0.1s linear;
}

.rotate.down {
  -moz-transform: rotate(90deg);
  -webkit-transform: rotate(90deg);
  transform: rotate(90deg);
}
.accordion {
background: blue;
}
.fa, h4 {
color: white;
}
