有没有办法在ng2-bootstrap中构建移动导航栏? [英] Is there a way to build the mobile nav bar in ng2-bootstrap?
问题描述
我一直在实现ng2-bootstrap和Angular2.
I've been implementing ng2-bootstrap and Angular2.
我不知道如何打开/关闭移动导航栏.
I cannot figure out how to make the mobile navbar open / close.
这是尚不支持的功能吗?还是我想念什么?
更新，html:
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">
<img src="/logo.png" />
</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li router-active>
<a [routerLink]=" ['Index'] ">Summary<span class="sr-only">(current)</span></a>
</li>
<li router-active>
<a [routerLink]=" ['Portfolio'] ">Portfolio<span class="sr-only">(current)</span></a>
</li>
<li router-active>
<a [routerLink]=" ['About'] ">About<span class="sr-only">(current)</span></a>
</li>
</ul>
<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
<ul class="nav navbar-nav navbar-right">
<li dropdown keyboardNav="true">
<a href class="dropdown-toggle" role="button" aria-expanded="false" dropdownToggle>
<span class="glyphicon glyphicon-user" aria-hidden="true"></span>

推荐答案
您需要包含并使用折叠指令
首先，您导入指令
import { CollapseDirective } from 'ng2-bootstrap'
将其包含在组件指令中
@Component({ directives: [CollapseDirective] })
正如Akkusativobjekt在评论中指出的那样，指令(在angular 2的当前稳定版本中)不再放置在@Component属性中.
它们包含在NgModule属性中.
@NgModule({ declarations: [CollapseDirective] })
You need to include and use the collapse directive
first you import the directive
import { CollapseDirective } from 'ng2-bootstrap'
Include it in your components directives
@Component({ directives: [CollapseDirective] })
As pointed out by Akkusativobjekt in the comments, Directives (in the current stable version of angular 2) are no longer placed in the @Component attribute.
They are included in the NgModule attribute.
@NgModule({ declarations: [CollapseDirective] })
然后在您的控制器中创建一个变量以跟踪其是否折叠
export class MyController {
public isCollapsed: boolean = true;
}
并在模板中显示如下所示的行
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" >
您需要切换变量
<button type="button" class="navbar-toggle collapsed" (click)="isCollapsed = !isCollapsed" >
此外，您还需要在模板中更改以下行:
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
包含指令
<div id="navbar" class="navbar-collapse collapse" [collapse]="isCollapsed">
有关ng2-bootstrap崩溃的文档
在html中使用崩溃指令的示例
NgModule的文档
then in your controller create a variable to keep track of whether or not it's collapsed
export class MyController {
public isCollapsed: boolean = true;
}
and in your template the line that looks like this
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" >
you'll want to toggle the variable
<button type="button" class="navbar-toggle collapsed" (click)="isCollapsed = !isCollapsed" >
And also in your template you'll want to change the line that says
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
to include the directive
<div id="navbar" class="navbar-collapse collapse" [collapse]="isCollapsed">
