ASP.NET Zero--12.一个例子（5）商品分类管理-编辑分类

1.添加编辑按钮

打开文件Index.js

【..\MyCompanyName.AbpZeroTemplate.Web\Areas\Mpa\Views\Category\Index.js】

在actions中添加如下代码：

actions: {
                    title: app.localize('Actions'),//操作列
                    width: '15%',
                    sorting: false,
                    display: function (data) {
                        var $span = $('<span></span>');
                        $('<button class="btn btn-default btn-xs" title="' + app.localize('Edit') + '"><i class="fa fa-edit"></i></button>')
                                .appendTo($span)
                                .click(function () {
                                    _editModal.open({ id: data.record.id });
                                });
                        return $span;
                    }
                },

效果如下：

 

2.模态框创建

同样，编辑也需要弹出一个模态框，然后修改值进行保存。

在Category目录下新建一个视图_EditModal.cshtml，代码如下：

@using MyCompanyName.AbpZeroTemplate.Web.Areas.Mpa.Models.Common.Modals
@Html.Partial("~/Areas/Mpa/Views/Common/Modals/_ModalHeader.cshtml", new ModalHeaderViewModel("编辑分类"))

<div class="modal-body">
    <form name="CategoryForm">
        <input type="hidden" name="Id" value="@Model.Id" />
        <div class="form-group form-md-line-input form-md-floating-label">
            <input type="text" name="Name" value="@Model.Name" class="form-control edited" required >
            <label>名称</label>
        </div>
    </form>
</div>

@Html.Partial("~/Areas/Mpa/Views/Common/Modals/_ModalFooterWithSaveAndCancel.cshtml")

同样再新建一个js文件_EditModal.js，代码如下：

var EditCategoryModal = (function ($) {
    app.modals.EditCategoryModal = function () {

        var _modalManager;
        var _categoryService = abp.services.app.category;
        var _$categoryForm = null;

        this.init = function (modalManager) {
            _modalManager = modalManager;

            _$categoryForm = _modalManager.getModal().find('form[name=CategoryForm]');
            _$categoryForm.validate();
        };

        this.save = function () {
            if (!_$categoryForm.valid()) {
                return;
            }

            var category = _$categoryForm.serializeFormToObject();

            _modalManager.setBusy(true);
            _categoryService.updateCategory(
                category
            ).done(function () {
                abp.notify.info(app.localize('SavedSuccessfully'));
                _modalManager.close();
                abp.event.trigger('app.editCategoryModalSaved');
            }).always(function () {
                _modalManager.setBusy(false);
            });
        };
    };
})(jQuery);

3.添加方法

打开ICategoryAppService文件，添加如下代码：

void UpdateCategory(CreateCategoryInput input);
CategoryOutput GetCategoryForEdit(EntityRequestInput input);

对应的实现类CategoryAppService，添加如下代码：

public void UpdateCategory(CreateCategoryInput input)
        {
int count = _categoryRepository.Count(a => a.Name.Equals(input.Name) && a.Id!=input.Id);
            if (count > )
            {
                throw new UserFriendlyException("分类名称已存在！");
            }
            var category=_categoryRepository.Get(input.Id);
            category.Name = input.Name;
        }

public CategoryOutput GetCategoryForEdit(EntityRequestInput input)
        {
            var category = _categoryRepository.Get(input.Id);
            return new CategoryOutput()
            {
                Id = category.Id,
                Name = category.Name
            };
        }

4.修改Index.js

...
var _createModal = new app.ModalManager({
            viewUrl: abp.appPath + 'Mpa/Category/CreateModal',//加载视图
            scriptUrl: abp.appPath + 'Areas/Mpa/Views/Category/_CreateModal.js',//加载对应js
            modalClass: 'CreateCategoryModal'
        });

        var _editModal = new app.ModalManager({
            viewUrl: abp.appPath + 'Mpa/Category/EditModal',
            scriptUrl: abp.appPath + 'Areas/Mpa/Views/Category/_EditModal.js',
            modalClass: 'EditCategoryModal'
        });
...
//事件注册
        abp.event.on('app.createCategoryModalSaved', function () {
            getCategories(true);
        });

        abp.event.on('app.editCategoryModalSaved', function () {
            getCategories(true);
        });

5.控制器

打开CategoryController，添加如下代码：

private ICategoryAppService _categoryAppService;
        public CategoryController(ICategoryAppService categoryAppService)
        {
            _categoryAppService = categoryAppService;
        }
...
public ActionResult EditModal(int id)
        {
            CategoryOutput category=_categoryAppService.GetCategoryForEdit(new EntityRequestInput(id));
            CategoryViewModel categoryViewModel=new CategoryViewModel()
            {
                Id = category.Id,
                Name = category.Name
            };
            return PartialView("_EditModal", categoryViewModel);
        }

6.添加ViewModel

在..MyCompanyName.AbpZeroTemplate.Web\Areas\Mpa\Models下新建一个目录Category

在Category下新建CategoryViewModel.cs

代码如下：

public class CategoryViewModel
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

7.测试

生成项目，刷新页面，点击编辑按钮

这一次，已经把数据验证一并完成。
