如何使用数据用户输入表单来创建弹出窗口? [英] How do I create popup with data user enters into a form?

问题描述

<!--Currently making web app that is a bunch of forms. 

我使用Angular 7使用Visual Studio 2017 ASP.NET Core 2.2创建的.当用户填写表格时，并非所有表格数据都是必需的.用户输入所需的表单信息后，我希望有一个按钮，弹出一个包含所有用户输入的数据和相应问题的弹出窗口.如果他们在表单上的文本框留空或输入n/a，我不希望该信息出现在弹出窗口中.我希望弹出窗口具有一个按钮，用于复制将粘贴到另一个站点上的表单中的数据.

I created using Visual Studio 2017 ASP.NET Core 2.2 with Angular 7. When user fills out form not all form data is required. After user enters desired form information I want there to be a button that brings up a popup that contains all user entered data and corresponding questions. If they leave a textbox on the form blank or enter n/a I do not want the information to appear in the popup. I want the popup to have a button to copy data that will be pasted into form on another site.

I have created all my forms and also know how to create a popup.

我唯一的问题是我不知道如何将用户输入的信息从表单填充/传输到弹出窗口，并排除用户未填写的文本框.-->

My only issue is I have no idea how to populate/transfer user entered information from form into the popup and excluding the text boxes not filled out by user.-->

<!-- this is th .html -->

<form [formGroup]="Form" (ngSubmit)="onSubmit()">

    <div class="form-row align-items-center">

推荐答案

您要尝试做的事情非常简单，并且您已经准备了很多东西(例如响应式表单)来实现它.

What you're attempting to do is pretty straightforward, and you've got a lot of things already in place (like reactive forms) to make it happen.

您拥有的模态很好，但是您可能应该对弹出窗口使用单独的组件，并将信息传递给它，如下所示:

Your modal you've got is fine, but you probably ought to use a separate component for the popup, and to pass information to it, it would look like this:

在您的调用模板中，包括一些模板，该模板将具有用于弹出窗口或模式窗口或包含组件的内容的模板，如下所示:

Within your calling template, include some template that will have a template for the popup or modal or whatever, which contains the component, see below:

<ng-template #formPopup>
    <form-popup
        [select1]="Form.get( 'Select1' ).value"
        [number]="Form.get( 'Number' ).value"
        [purpose]="Form.get( 'Purpose' ).value"
        [name]="Form.get( 'name' ).value">
    </form-popup>
</ng-template>

这将在创建组件时将这些值作为输入传递给它们:

This will pass these values in as inputs as they are into your component when it's created:

export class FormPopupComponent {
    @Input() select1 : any;
    @Input() number : number;
    @Input() purpose : string;
    @Input() name : string;

    // Do things with these inputs as needed in this component
}

正如您所指出的那样，单击时还必须打开对话框或弹出窗口或其他内容，对此进行了描述在此处详细.但是，这里有一个简短的摘要-在您的原始表单模板的组件中，您需要引用我们已经创建的弹出窗口:

On click, as you pointed out, you'll also have to open your dialog or popup or whatever, which is described in detail here. But here's a quick summary - in your component for your original form-containing template, you'll need a reference to your popup, which we've already created:

@ViewChild( 'formPopup' ) formPopupRef : TemplateRef<any>;

constructor(public dialog: MatDialog) {}

    openDialog(): void {
        const dialogRef = this.dialog.open( this.formPopupRef );
    }
