在角度2中使用打字稿来关闭引导程序模态 [英] Close bootstrap modal using typescript in angular 2

问题描述

我有一个按钮，单击该按钮会打开一个引导模式弹出窗口.模态弹出窗口包含带有提交按钮的某些字段.我只想在保存完数据后关闭弹出窗口.我无法使用数据删除功能，因为它会在用户点击按钮后立即关闭弹出窗口.有没有办法通过打字稿关闭弹出窗口?

I have a button, on the click of which I am opening a bootstrap modal pop-up. The modal pop-up contains some field with a submit button. I want to close the pop-up only when I am done saving the data. I can't use data-dismiss as it will close the pop-up right after user hits the button. Is there a way to close the pop-up through typescript?

推荐答案

您可以使用关闭按钮上的操作

you can use the action on close button

<div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" #closeAddExpenseModal>&times;</button>
                <h4 class="modal-title">Add Expense</h4>
            </div>

在您的控制器中，您可以在执行操作后添加此行

and in your controller you can add this line after the action you use

this.closeAddExpenseModal.nativeElement.click();

您将需要将此导入添加到您的控制器

you will need to add this imports to your controller

import { ViewChild, ElementRef} from '@angular/core';

您还需要定义closeAddExpenseModal

you will need also to define closeAddExpenseModal

@ViewChild('closeAddExpenseModal') closeAddExpenseModal: ElementRef;
