等效于Angular 7的$ location.search() [英] $location.search() equivalent in Angular 7

问题描述

我正在将Angular JS迁移到Angular7.我正在查看这段代码，并尝试在Angular 7中实现.

I am migrating Angular JS to Angular 7. I am looking at this code and trying to implement in Angular 7.

在服务中，注入了$location，以下方法重置并设置了查询参数.

In the service, $location was injected, and the following methods reset and set the query parameters.

function resetAllOptions() {
            // Clears query params
            $location.search('');

}

function setQueryParameters() {
    // Sets query parameters
            $location.search({
                searchType: searchType,
                searchField: searchField,
                searchValue: searchValue,
                searchValueTwo: searchValueTwo,
                searchValueThree: searchValueThree
            });
}

如何在Angular 7中实现呢?

How do I implement this in Angular 7?

推荐答案

在Angular v7中，参数是完全不同的，因为它们是路由"的一部分.因此，没有直线等效于您要完成的工作.

Parameters are done completely differently in Angular v7 as they are a part of Routing. So there is no direct line to line equivalent of what you are trying to accomplish.

在Angular v2 +中，存在三种不同类型的参数，因此第一步是定义所需的类型.

In Angular v2+, there are three different types of parameters, so your first step is to define the type that you want.

这是一篇详细描述不同类型的文章:

Here is a post that describes the different types in detail:

通过Angular中的路由路径发送数据

假设您要坚持使用查询参数:

Assuming you want to stick with Query parameters:

您可以像这样在HTML中进行设置:

You can set them in the HTML like this:

          <a [routerLink]="[product.id]"
             [queryParams]="{filterBy: listFilter, showImage: showImage}">
            {{ product.productName }}
          </a>

或者在这样的代码中:

this.router.navigate([`/search`],
              {queryParams: {
                     searchType: searchType,
                     searchField: searchField, // ...
               }});
