我正在使用Mat对话框,该对话框在ap-fullcalendar上单击事件时执行。我正在使用Angular6。
当我单击一个事件时,将显示以下对话框,没有任何信息。
按下“购买”按钮后,它将带我进入实际的对话框。
注意:这些按钮似乎没有按预期工作,但是,我认为这是我的原始问题。 另外,当我双击事件时,在对话框打开的地方,我得到了不同的行为,如第一个屏幕截图所示。当我按下或取消时,它会关闭。
感谢您的帮助!

import { MatDialog, MatDialogRef, MAT_DIALOG_DATA } from '@angular/material';
import { CalendarComponent } from 'ap-angular2-fullcalendar/src/calendar/calendar';

import { DialogComponentComponent } from './dialog-component/dialog-component.component';
export interface DialogData {

this.calendarService.getEvents(this.subjectFilter).subscribe(data => {
console.log(data);
this.calendarOptions = {

onNoClick(): void {
this.dialogRef.close();

我的对话框组件HTML:

我遇到了与此非常相似的问题。我正在网上搜索并尝试查看是否有任何可修复的线索,因为它似乎不像您想出了答案。
我能够解决问题,但是我不确定是什么原因。我所做的是一个npm update
,然后删除了node_modules
文件夹并运行了一个全新的npm install
接下来,我遇到其他一些人遇到类似问题的问题。通过调用window
弹出对话框,您似乎很容易出现问题。原来,部分问题是正在NgZone之外发生对话,因此要修复import {NgZone} from '@angular/core'
,
将其包含在构造函数constructor(private dialog: MatDialog, readonly ngZone: NgZone)
中,然后在打开对话框时使用
this.ngZone.run(() => {
const ref = this.dialog.open(DialogComponent, {
options..,
data: {}
});
...
});`

您可以手动触发更改检测。这是更新的代码。
import {ChangeDetectorRef} from '@angular/core';
constructor(private cdr: ChangeDetectorRef){}
openDialog(calEvent): void {
console.log("opendialog");
setTimeout(()=>{
const dialogRef = this.dialog.open(DialogComponentComponent, {
data : {
title: calEvent.title,
start: calEvent.start,
end: calEvent.end,
price: calEvent.price
}
});
}, 0);
dialogRef.afterClosed().subscribe(result => {
console.log('The dialog was closed');
});
// this.cdr.detectchanges();
}
