如果用户尝试在不保存表单的情况下导航出页面,我需要通过 CanDeactivate routeguard 触发一个对话框。我正在遵循此处建议的解决方案。
我想自定义示例中使用的确认对话框,使用我们在整个应用程序中使用的自定义模式对话框。我打算使用Kendo Dialog Service来做。我在我的应用程序中的一个现有组件上使用了与链接中给出的完全相同的示例,但它引发了以下控制台错误:
Cannot attach dialog to the page.
Add an element that uses the kendoDialogContainer directive, or set the 'appendTo' property.

奇怪的是,我确实kendoDialogContainer
在页面上添加了指令。
仪表板.html:
<button kendoButton (click)="open()">Harmless button</button>
<div kendoDialogContainer></div>
仪表板.component.ts:
import { DialogCloseResult, DialogService } from '@progress/kendo-angular-dialog';
public open() {
var dialog = this.dialogService.open({
title: "Please confirm",
content: "Are you sure?",
actions: [
{ text: "No" },
{ text: "Yes", primary: true }
]
});
dialog.result.subscribe((result) => {
if (result instanceof DialogCloseResult) {
console.log("close");
} else {
console.log("action", result);
}
});
}
知道哪里出错了吗?
提前致谢。
