ASP.NET 核心 MVC 在产品页面详细信息上应用同位素过滤器

ASP.NET Core MVC apply isotope filter on product page details

我在我的 .Net 核心项目上动态应用了同位素过滤器。我成功地做到了,但发生了一个小错误。选择产品的特定类别位置后,不会排在第一位。下面看我的两张图

All Product

After Filter check the position of that image not changed(its need to come first)

我的代码如下 Index.cshtml

@model BornoMala.Models.ViewModels.ProductDetailsVM
<section id="portfolio" class="portfolio">
    <div class="container">
        <div class="row" data-aos="fade-up">
            <div class="col-lg-12 d-flex justify-content-center">
                <ul id="portfolio-flters">
                    <li data-filter="all" class="filter-active filter-button">All</li>
                    @foreach (var obj in Model.Categories)
                    {
                        <li class="filter-button" data-filter="@obj.Name.Replace(' ','_')">@obj.Name</li>
                    }
                </ul>
            </div>
        </div>

        <div class="row portfolio-container" data-aos="fade-up">
            @foreach (var prod in Model.Products)
            {
                <div class="col-lg-4 col-md-6 portfolio-item  filter @Model.Category.Name.Replace(' 
                 ','_')">
                   <div class="portfolio-img"><img src="@Model.ImageUrl" class="img-fluid" alt=""></div>
                    <div class="portfolio-info">
                    <h4>@Model.Title</h4>
                    <p>By <b>@Model.Title</b></p>
                    </div>
                  </div>
            }
        </div>

    </div>
</section>

Isotope.js

$(window).on('load', function () {
        var portfolioIsotope = $('.portfolio-container').isotope({
            itemSelector: '.portfolio-item',
        });
});

 $(document).ready(function () {

            $(".filter-button").click(function () {
                $("#portfolio-flters li").removeClass('filter-active');
                $(this).addClass('filter-active');

                var value = $(this).attr('data-filter');
                if (value == "all") {
                    $('.portfolio-item').show('3000');
                }
                else {
                    $(".portfolio-item").not('.' + value).hide('2000');
                    $('.portfolio-item').filter('.' + value).show('2000');

                }
            });

    });

如果我从 isotope.js 中删除 ..portfolio-container class on load window 然后详细信息页面容器不灵活检查我的另一个图像(但过滤器工作正常)..

Image card not flexible

有两种方法:

1,只将window的onload部分改成:

$('.portfolio-container').isotope({
        itemSelector: '.element-item'
    });

然后它会显示给第一个,但是在我的演示中移动需要一些时间

2、尝试另一种使用同位素的方法:

注意'portfolio-flters'中的data-filter内容,可能和你的不一样。这条路

原理是当你点击不同的过滤器按钮时每次调用同位素

(不同的数据过滤器)。

编辑代码:

Mind data-filter=".@obj.Name.Replace(' ','_')">@obj.Name</li> 数据库中存储的数据

是数字,但您可以添加'.'在'@'之前,所以可以同位素识别。

<div class="container">
<div class="row" data-aos="fade-up">
    <div class="col-lg-12 d-flex justify-content-center">
        <ul id="portfolio-flters">
            <li data-filter="*" class="filter-active filter-button">All</li>
            @foreach (var obj in Model.Categories)
            {
                <li class="filter-button" data-filter=".@obj.Name.Replace(' ','_')">@obj.Name</li>
            }
        </ul>
    </div>
</div>
<div class="row portfolio-container" data-aos="fade-up">
    @foreach (var product in Model.Products)
    {
        <partial name="_IndividualProductCard" model="product" />
    }
</div>
@section Scripts
{
<script src="https://unpkg.com/isotope-layout@3/dist/isotope.pkgd.js"></script>
<script src="https://unpkg.com/isotope-layout@3/dist/isotope.pkgd.min.js"></script>
<script>
    $mygrid = $('.portfolio-container').isotope({
        itemSelector: '.portfolio-item'
    });

    $('#portfolio-flters').on('click', 'li', function () {
        var filterValue = $(this).attr('data-filter');
        $mygrid.isotope({ filter: filterValue });
    });
</script>
}

数据库中的数据:

结果:

@Tisa 我按照你说的那样遵循你的代码 Index.cshtml

<section  class="portfolio">
    <div class="container">
        <div class="row" data-aos="fade-up">
            <div class="col-lg-12 d-flex justify-content-center">
                <ul id="portfolio-flters">
                    <li data-filter="*" class="filter-active filter-button">All</li>
                    @foreach (var obj in Model.Categories)
                    {
                        <li class="filter-button" data-filter="@obj.Name.Replace(' 
                        ','_')">@obj.Name</li>

                    }

                </ul>
            </div>
        </div>
        <div class="row portfolio-container" data-aos="fade-up">
            @foreach (var product in Model.Products)
            {
                <partial name="_IndividualProductCard" model="product" />
            }

        </div>

    </div>
</section>

_IndividualProductCard.cshtml

@model BornoMala.Models.Product
<div class="col-lg-4 col-md-6 portfolio-item  filter @Model.Category.Name.Replace(' ','_')">
    <div class="portfolio-img ">
        <img src="@Model.ImageUrl" width="100" height="50" />

        <script>
            $mygrid = $('.portfolio-container').isotope({
                itemSelector: '.portfolio-item'
            });

            $('#portfolio-flters').on('click', 'li', function () {
                var filterValue = $(this).attr('data-filter');
                $mygrid.isotope({ filter: filterValue });
            });
        </script>
    }

产品型号

namespace project.Models
{
    public class Product
    {
        [Key]
        public int Id { get; set; }

        [Required]
        public string Title { get; set; }

        [Required]
        public string Description { get; set; }

        [Required]
        public string Artist { get; set; }

        [Required]
        [Range(1,1000)]
        public double Price { get; set; }

        public string ImageUrl { get; set; }

        [Required]
        public int CategoryId { get; set; }

        [ForeignKey("CategoryId")]
        public Category Category { get; set; }

        [Required]
        public int StyleId { get; set; }

        [ForeignKey("StyleId")]
        public Style Style { get; set; }
    }
}

productdetailsVM

namespace project.Models.ViewModels
{
    public class ProductDetailsVM
    {
        public IEnumerable<Product> Products { get; set; }
        public IEnumerable<Category> Categories { get; set; }
        
    }
}

但是所有类别图片显示其他没有图片显示 blank image

我已经用 jquery 修复了过滤,但问题是图片位置没有改变,因为“$mygrid”没有调用所以如何调用那个

@section Scripts{

    <script src="https://unpkg.com/isotope-layout@3/dist/isotope.pkgd.js"></script>
    <script src="https://unpkg.com/isotope-layout@3/dist/isotope.pkgd.min.js"></script>
   <script>
            $mygrid = $('.portfolio-container').isotope({
                itemSelector: '.portfolio-item'
            });

            $(".filter-button").click(function(){

                var value = $(this).attr('data-filter');
                if(value == "all")
                 {
                   $('.filter').show('0010');
                 }
            else
                  {
                    $(".filter").not('.'+value).hide('0010');
                    $('.filter').filter('.'+value).show('0010');

               }
            });
   </script>
