Angular2 Routerlink:添加查询参数 [英] Angular2 Routerlink: add query parameters

问题描述

如何向 routerLink 添加查询参数?

How can I add query parameters to routerLink?

@RouteConfig {
   {path: '/search',   name: 'Search', component: SearchCmp}
}  

假设我想路由到 /search?q=asdf，

<a [routerLink]= " [ '/Search' , {q= 'asdf'}] ">Link 1</a>

这解析为 /search .

有没有办法在不使用的情况下添加查询参数:

Is there a way to add query parameters without using:

this.router.navigate( ['Search', { q: 'asdf'}]);

或

<a href="/search?a=asdf"> Link 2 </a>

?

推荐答案

如果你需要像 /search?q=asdf 这样的东西，你可以简单地使用:

If u need something as /search?q=asdf than you can simply use:

@RouteConfig {
   {path: '/search',   name: 'Search', component: SearchCmp}
}

//And to generate router Links use:

<a [routerLink]="['/Search']" [queryParams]="{q:'asdf'}"></a>

这将生成 href 标记为 <a href="/search" 但单击锚标记将引导您到 url /search?q=asdf.[queryParams] 会让你添加带有?"的查询参数，否则它们会被附加;".您可以使用以下方法在 SearchCmp 中获取此参数:

This will generate the href tag as <a href="/search" but on clicking the anchor tag will lead you to url /search?q=asdf. [queryParams] will let you add the query params with "?", otherwise they will be appended by ";". You can get this parameter in your SearchCmp using:

constructor(private _routeParams: RouteParams) {
   var queryParam = this._routeParams.get('q');
}
