在angular7中实现引导模式对话框 [英] Implementing bootstrap modal dialog in angular7
问题描述
我在实现一个简单的引导程序模态对话框上停留了一段时间，并在大约10个不同的页面中找到了答案.考虑到我无法快速找到答案，也没有明确地我想分享自己的解决方案来帮助他人. (下面的第一个答案)
I was stuck for a while on implementing a simple bootstrap modal dialog box and found pieces of the answer in about 10 different pages. Considering I couldn't find the answer quickly nor clearly I thought I'd share my solution to help others. (first answer below)
如果您必须添加多种类型的引导窗口小部件，我建议您看一下( https://ng-bootstrap.github.io/#/home )
In case you have to add multiple types of bootstrap widgets I suggest taking a look at (https://ng-bootstrap.github.io/#/home)
推荐答案
在 src/index.html 中，我将body标签的内容更改为:
In the src/index.html I changed the content of the body tag to:
<body>
<app-root></app-root>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js">
</script>
</body>
在调用模态的组件中，我在模板中:
In the component, which calls the modal, I have in the template:
<!-- Button to Open the Modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal" (click)="showModal()">
Open modal
</button>
<app-modal></app-modal>
在打字稿组件中
showModal(): void {
this.displayService.setShowModal(true);
// communication to show the modal, I use a behaviour subject from a service layer here
}
我在模版中为模态构建了一个单独的组件
I build a separate component for the modal, in the template I have
<!-- The Modal -->
<div class="modal fade" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<!-- Modal Header -->
<div class="modal-header">
<h4 class="modal-title">Modal Heading</h4>
<button type="button" class="close" (click)="hideModal()">×</button>
</div>
<!-- Modal body -->
<div class="modal-body">
Modal body..
</div>
<!-- Modal footer -->
<div class="modal-footer">
<button type="button" class="btn btn-primary" (click)="sendModal()" >Send</button>
<button type="button" class="btn btn-danger" (click)="hideModal()">Close</button>
<!-- this button is hidden, used to close from typescript -->
<button type="button" id="close-modal" data-dismiss="modal" style="display: none">Close</button>
</div>
</div>
</div>
</div>
在Typescript组件中，我有
And in the Typescript component I have
import { Component, OnInit } from '@angular/core';
// This lets me use jquery
declare var $: any;
@Component({
selector: 'app-modal',
templateUrl: './modal.component.html',
styleUrls: ['./modal.component.css']
})
export class ModalComponent implements OnInit {
constructor() { }
ngOnInit() {
}
showModal():void {
$("#myModal").modal('show');
}
sendModal(): void {
//do something here
this.hideModal();
}
hideModal():void {
document.getElementById('close-modal').click();
}
}
现在，模态对话框可以工作了，它具有一个发送功能(可以在其中添加一些其他逻辑)和一个隐藏功能，用于从打字稿中关闭模态
Now the modal dialog works, has a send function where some additional logic can be, and a hide function to close the modal from typescript
