javascript - JQuery 升序和降序排序(不是表格)

Question

我在 MVC5 中排序价格的脚本有问题

这是一个 View

@model IEnumerable<WebApplication.Models.Product>
@foreach (var Model in Model){
   <div class="col-md-3">
    <div class="product-men">

        <div class="men-pro-item simpleCart_shelfItem">

            <div class="men-thumb-item">
                <img src="~/Images/@Model.Product_Image" alt="" class="pro-image-front">
                <img src="~/Images/@Model.Product_Image" alt="" class="pro-image-back">
                <div class="men-cart-pro">
                    <div class="inner-men-cart-pro">
                        <a href="single.html" class="link-product-add-cart">Quick View</a>
                    </div>
                </div>


            </div>
            <div class="item-info-product">
                <h4><a href="">@Model.Product_Name</a></h4>
                <div class="info-product-price">
                    <span class="item_price price"><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="3e1a7e73515a5b52106e4c515a4b5d4a" rel="noreferrer noopener nofollow">[email protected]</a>_Discount</span>
                    @if (Model.Product_Discount == Model.Product_Price)
                    {
                    }
                    else
                    {
                        <del><a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f3d7b3be9c97969fdda3819c97869087" rel="noreferrer noopener nofollow">[email protected]</a>_Price</del>}

                </div>
                <div class="snipcart-details top_brand_home_details item_add single-item hvr-outline-out button2">
                    <form action="#" method="post">
                        <fieldset>
                            <input type="hidden" name="cmd" value="_cart" />
                            <input type="hidden" name="add" value="1" />
                            <input type="hidden" name="business" value=" " />
                            <input type="hidden" name="item_name" value="Formal Blue Shirt" />
                            <input type="hidden" name="amount" value="30.99" />
                            <input type="hidden" name="discount_amount" value="1.00" />
                            <input type="hidden" name="currency_code" value="USD" />
                            <input type="hidden" name="return" value=" " />
                            <input type="hidden" name="cancel_return" value=" " />
                            <input type="submit" name="submit" value="Add to cart" class="button" />
                        </fieldset>
                    </form>
                </div>
            </div>
        </div>
    </div>
</div>}

片段:

var ascending = false;

$('.tab-content').on('click', '.sortByPrice', function() {

  var sorted = $('.men-pro-item').sort(function(a, b) {
    return (ascending ==
      (convertToNumber($(a).find('.price').html()) <
        convertToNumber($(b).find('.price').html()))) ? 1 : -1;
  });
  ascending = ascending ? false : true;

  $('.product-men').html(sorted);
});

var convertToNumber = function(value) {
  return parseFloat(value.replace('$', ''));
}

<!-- Need to add the html data before click, here -->



<!-- Button click sort -->
<div class="tab-content">
  <h6>Sort By</h6>
  <div id="filters">
    <p>
      <a class="sortByPrice" href="#">Sort by Price</a>
    </p>
  </div>
  <div class="clearfix"></div>
</div>

当我单击“按价格排序”时出现此问题，此 JavaScript 运行良好，但存在重复数据。因为foreach。但我无法删除这个 foreach。帮助我修复此代码或新代码(如果有)。不是表

我研究了你的代码，最终得到了与斯蒂芬在他的评论中谈论的相同的解决方案(我在完成后立即看到了这一点)。

这是一个工作片段，我在其中添加了一些值来模拟它:

var ascending = false;

$('.tab-content').on('click', '.sortByPrice', function() {

  var sorted = $('.men-pro-item').sort(function(a, b) {
    return (ascending ==
      (convertToNumber($(a).find('.price').html()) <
        convertToNumber($(b).find('.price').html()))) ? 1 : -1;
  });
  ascending = ascending ? false : true;

  $('#products').html(sorted); // Modified

});

var convertToNumber = function(value) {
  return parseFloat(value.replace('$', ''));
}

h4 {
  margin: 0;
}

.item-info-product * {
  display: inline-block;
}

希望对您有所帮助。
