Getting started

$3

You can install the latest version using npm:

``shell npm install react-st-modal`

`$3`


To implement the functionality of modal dialogs this library has four functions and one react component.

Functions Alert, Confirm, Prompt implement the behavior of existing browser functions.

Function CustomDialog shows any JSX element in a modal window.

React component StaticDialog is used to define modals in your JSX element.

`$3`


All interaction functions are async.
| Method name | Parameters | Return type | Description|
| ----------- | ---------- | ----------- | ---------- |
|

Alert | body: JSX.Element (string), title?: string, buttonText?: string | void | Shows a message (body

) and waits for the user to press button |
|

Confirm | body: JSX.Element (string), title?: string, okButtonText?: string, cancelButtonText?: string | boolean | Shows a modal window with a text (body) and two buttons: OK and Cancel. The result is true if OK is pressed and false

 otherwise|
|

Prompt |title?: string, options?: PromptConfig | string | Shows a modal window with a text message, an input field for the visitor, and the buttons OK/Cancel|

PromptConfigallows you to specify the following optional parameters: *defaultValue: string | number*isRequired: boolean*errorText: string*okButtonText: string*cancelButtonText: string

Example

`jsx import { Confirm } from 'react-st-modal';

function ConfirmExample() { return (


              onClick={async () => {
          const result = await Confirm('Сonfirmation text', 
            'Сonfirmation title');
          
          if (result) {
            // Сonfirmation confirmed
          } else {
            // Сonfirmation not confirmed
          }
        }}
      >
          Show confirm


  );
}

To control a dialog from an inner element, use useDialog hook

Example`jsx import { CustomDialog, useDialog } from 'react-st-modal';

// The element to be shown in the modal window function CustomDialogContent() { // use this hook to control the dialog const dialog = useDialog();

const [value, setValue] = useState();

return (


              type="text"
        onChange={(e) => {
          setValue(e.target.value);
        }}
      />
              onClick={() => {
          // Сlose the dialog and return the value
          dialog.close(value);
        }}
      >
        Custom button


  );
}
function CustomExample() {
