实战 Menu 导航菜单使用(1)

[densen2014]

1.Menu 导航菜单

为页面和功能提供导航的菜单列表。

@code{
 //演示数据
 private IEnumerable<MenuItem>? Items { get; set; } = new List<MenuItem>
            { 
                new MenuItem() { Text = "维保管理", Icon = "fa fa-address-book", Url = "/"  , Match = NavLinkMatch.All},
                new MenuItem() { Text = "车主", Icon = "fa fa-address-book", Url = "/owners" ,Items=new List<MenuItem>() {
                    new MenuItem() { Text = "车主列表", Icon = "fa fa-address-book", Url = "/owners"  , Match = NavLinkMatch.All},
                    new MenuItem() { Text = "车主添加", Icon = "fa fa-address-book", Url = "/owners/add"  , Match = NavLinkMatch.All},
                }},
                new MenuItem() { Text = "车辆", Icon = "fa fa-fw fa-car", Url = "/cars" },
                new MenuItem() { Text = "保险", Icon = "fa fa-fw fa-fa", Url = "/insurans"},
                new MenuItem() { Text = "出险记录", Icon = "fa fa-map-o", Url = "/insurancerecords"},
                new MenuItem() { Text = "花名册", Icon = "fa fa-fw fa-users", Url = "users" }
            };
}

顶栏

适用广泛的基础用法。

<Menu Items="@Items" DisableNavigation="true" OnClick="@OnClickMenu" />

@code{
 private Task OnClickMenu(MenuItem item)
    {
        System.Console.WriteLine($"菜单点击项: {item.Text}");
        return Task.CompletedTask;
    }
}

底栏

设置参数 IsBottom 值为 true 菜单栏在容器底部，适用移动端

<div style="height: 120px">
    <Menu Items="@Items" DisableNavigation="true" IsBottom="true" />
</div>

带图标的顶栏菜单

适用简单的网站应用，通过设置菜单项 MenuItem 的 Icon 属性设置菜单图标

new MenuItem() { Text = "维保管理", Icon = "fa fa-address-book"} 

侧栏

适用于左右结构布局的网站，通过设置 IsVertical 更改导航菜单为侧栏

<div style="width:220px; border-right: 1px solid #e6e6e6; padding-right: 4px;">
    <Menu Items="@Items" DisableNavigation="true" IsVertical="true" />
</div>

带图标的侧栏菜单

通过设置菜单项 MenuItem 的 Icon 属性设置菜单图标

<div style="width:220px;">
    <Menu Items="@Items" DisableNavigation="true" IsVertical="true" style="border-right: 1px solid #e6e6e6;" />
</div>

手风琴效果的侧栏

通过设置 IsAccordion 属性设置手风琴特效侧栏菜单

<div style="width:220px;">
    <Menu Items="@Items" DisableNavigation="true" IsVertical="true" IsAccordion="true" style="border-right: 1px solid #e6e6e6;" />
</div>

动态更改菜单

通过代码动态设置 Items 属性值更改菜单项

<div class="mt-3" style="width:220px;">
    <Menu Items="@DynamicSideMenuItems" DisableNavigation="true" IsVertical="true" style="border-right: 1px solid #e6e6e6;" />
</div>
<Button Text="更新菜单" OnClick="UpdateMenu" />
<Button Text="重置菜单" OnClick="ResetMenu" />

@code{

    private IEnumerable<MenuItem>? DynamicSideMenuItems { get; set; }

    private Task UpdateMenu()
    {
        DynamicSideMenuItems = new List<MenuItem>
            { 
                new MenuItem() { Text = "维保管理", Icon = "fa fa-address-book", Url = "/"  , Match = NavLinkMatch.All},
                new MenuItem() { Text = "车主", Icon = "fa fa-address-book", Url = "/owners" ,Items=new List<MenuItem>() {
                    new MenuItem() { Text = "车主列表", Icon = "fa fa-address-book", Url = "/owners"  , Match = NavLinkMatch.All},
                    new MenuItem() { Text = "车主添加", Icon = "fa fa-address-book", Url = "/owners/add"  , Match = NavLinkMatch.All},
                }}
            };
        return Task.CompletedTask;
    }

    private async Task ResetMenu()
    {
        DynamicSideMenuItems = new List<MenuItem>
            { 
                new MenuItem() { Text = "维保管理", Icon = "fa fa-address-book", Url = "/"  , Match = NavLinkMatch.All},
                new MenuItem() { Text = "保险", Icon = "fa fa-fw fa-fa", Url = "/insurans"},
                new MenuItem() { Text = "出险记录", Icon = "fa fa-map-o", Url = "/insurancerecords"},
                new MenuItem() { Text = "花名册", Icon = "fa fa-fw fa-users", Url = "users" }
            };
        return Task.CompletedTask;
    }
}

等等....
