我有一个角度2组件,需要导航到另一个路线,但在不同的浏览器选项卡中.下面的代码在同一浏览器选项卡中导航.

    import { Component } from '@angular/core';
    import { Router } from '@angular/router';

    @Component({
         templateUrl: 'quotes-edit.component.html'
    })

    export class QuoteComponent {
         constructor(private router: Router) {
         }

         this.router.navigate(['quote/add']);
    }

我在html页面中使用了以下插值.

<div>{{config.CompanyAddress.replace('\n','<br />')}}</div>

并且也使用了

<div>{{config.CompanyAddress.toString().replace('\n','<br />')}}</div>

但两者都显示如下文字

{{config.CompanyAddress.replace('\n','<br />')}}
{{config.CompanyAddress.toString().replace('\n','<br />')}}

在控制器中,我定义了$rootScope.tableformate变量来填充弹出窗口中的数据.

填充后$rootScope.tableformate不使用弹出数据.如何删除这个变量？

EF Core 3.1.x:

I would not like to load all products in memory, which below queries do! Guess what happen if i do have millions of products in table?

var products = context.Products.ToList();
products = products.Where(p => p.Name.Contains("xxx")).ToList();

And below query throws The LINQ expression 'DbSet-Product- .Where(b => b.Name.Contains( value: "xxx", comparisonType: InvariantCultureIgnoreCase))' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to either …

在下面的代码中发现未发现错误..绑定只应用一次,直到它显示不能多次应用绑定...是淘汰版本的问题？可以在immediatly调用函数中编写以下代码...

        var DummyContact = [
        {
            "ContactID": 1,
            "FirstName": "Nimesh",
            "LastName": "Vaghasiya"
        },
        {
            "ContactID": 2,
            "FirstName": "John",
            "LastName": "Cena"
        }
    ];

    var ContactViewModel = function () {
        var self = this;
        var url = "/Contacts/GetAllContacts";
        //var refresh = function () {
        //    $.getJSON(url, {}, function (data) {
        //        self.Contacts(data);
        //    });
        //};
        var refresh = function () {
            self.Contacts(DummyContact);
        };

        // public data properties
        self.Contacts = ko.observableArray([]);
        refresh();

        self.createContact = function () {
            window.location.href = '/Contacts/CreateEdit/0';
        };

        self.editContact = …

我有两个班级联系人和小组

组合FirstName和LastName必须是唯一的,可以为单个联系人添加多个地址.我如何才能在实体框架代码第一种方法中做到这一点？

public class Contacts
{
    [Key]
    public int ContactID { get; set; }
    [ForeignKey("Group")]
    public int GroupID { get; set; }
    [Required]
    public string FirstName { get; set; }
    [Required]
    public string LastName { get; set; }
    [Required]
    public string Address { get; set; }
    [Required]
    public string Number { get; set; }
    [Required]
    [EmailAddress]
    public string EmailId { get; set; }
    [DataType(DataType.Date)]
    public DateTime CreateDate { get; set; }
    public DateTime? ModifiedDate { get; …
