Text Field

The TextField component allows you to type text in your app. The TextField has attributes such as secure for handling password fields, and pipes for specifying the text format the control should use.

Usage

TextField provides multiple properties and several events for handling the user input and interaction. To submit a value use the returnPress event along with the returnKeyType property. To handle a TextField being focused use the focus event. To handle an interaction when the user leaves TextField use the blur event. To explicitly show and hide a keyboard, we can call the methods focus and dismissSoftInput.

<TextField hint="Enter Date" 
           [text]='name' 
           secure="false"
           keyboardType="datetime"
           returnKeyType="done" 
           (returnPress)="onReturnPress($event)"
           autocorrect="false"
           maxLength="10"
           (focus)="onFocus($event)" 
           (blur)="onBlur($event)">
</TextField>

        setTimeout(() => {

    onBlur(args) {
        // blur event will be triggered when the user leaves the TextField
        let textField = <TextField>args.object;
