问题描述
我有一个 Angular 4 页面,包括一个 ng-bootstrap 模式.我的代码如下所示.
I've got an angular 4 page including a ng-bootstrap modal. My code looks like this.
foo.html
[...]
<button class="btn btn-sm btn-secondary material-icons"
(click)="open(content)">search</button>
<ng-template #content let-c="close" let-d="dismiss">
content in here
</ng-template>
[...]
foo.ts
[...]
constructor(private modalService: NgbModal) { }
[...]
open(content) {
let options: NgbModalOptions = {
size: 'lg'
};
this.modalService.open(content, options);
}
[...]
现在,当我单击按钮时,模式会打开.我现在要做的是在 ngChanges 上打开模型.
Now when I click the button the modal opens. What I want to do now is open the model on ngChanges.
ngOnChanges(changes: any) {
open(content)
}
我的问题是:如何在这里获取内容"?有没有办法以编程方式获取 ng-template?提前致谢!
My problem is: How do I get the "content" here? Is there any way to get the ng-template programmatically? Thanks in advance!
推荐答案
要访问类中的 content
元素,请声明:
To access the content
element inside the class, declare:
@ViewChild('content', { static: false }) private content;
^for Angular8+
并在类的顶部添加相应的导入:
and add the corresponding import at the top of the class:
import { ViewChild } from '@angular/core';
最后在更改检测时为该元素调用 open 方法:
and finally call open method for that element on change detection:
ngOnChanges(changes: any) {
this.open(this.content);
}
