Custom Dialog in NativeScript

Question

I am learning NativeScript. As part of that effort, I am attempting to create a page that shows a dialog to the user. When the user clicks a button, I need to show them a dialog that allows them to enter two values (first name and last name).

The dialogs module in NativeScript provides several built-in options. However, from what I can tell, none of these options allow you to create a dialog that shows two fields. How do I create a dialog in NativeScript that will allow me to prompt a user to enter a first name and a last name? Currently, my page looks like this:

page.xml

<Page xmlns="http://www.nativescript.org/tns.xsd" loaded="pageLoaded">
  <GridLayout rows="auto, *">
      <Border borderWidth="1" borderColor="#000" width="28" height="28" cornerRadius="14" tap="addPersonButton_Tap">
        <Label text="add person" />
      </Border>      
  </GridLayout>
</Page>

page.js

var viewModel = new MyPageViewModel();
function pageLoaded(args) {
    var page = args.object;
    page.bindingContext = viewModel;        
}
exports.pageLoaded = pageLoaded;

function addPersonButton_Tap(args) {
    console.log('new person');
    /*
     * Dialog open code goes here. Yet, the following definitaly is not correct.
    dialogs.prompt({
        title: "Add New Person",
        message: "First Name",
        okButtonText: "Save",
        cancelButtonText: "Cancel",
        inputType: dialogs.inputType.text
    }).
    then(function (r) {
        if (r.result) {
          console.log('User clicked "Save"!');
        }
    });   
    */
}
exports.addPersonButton_Tap = addPersonButton_Tap;

We already support modal pages. Here you can see a demo with it: https://github.com/NativeScript/NativeScript/blob/7c13db6bc241c48d5897d556f2973944b8b750d6/apps/app/ui-tests-app/modal-view/modal-view.ts.

Moreover, you can also find the information you needed in the documentation:

• http://docs.nativescript.org/ui-dialogs#prompt
• http://docs.nativescript.org/api-reference/classes/_ui_page_.page.html#showmodal

I just wanted to mention one more thing. I saw that you are using the Border tag. Now you can use CSS styling instead.
