Select All Text on Focus

As of the 2020 R3 release, selecting the whole NumericTextBox input value on focus is available out of the box. For more information, refer to the selectOnFocus property.

The following example demonstrates how to select the whole NumericTextBox input value on focus.

<input id="numeric" type="number" value="17" min="0" max="100" step="1" />
<script type="text/javascript">
$(function () {
    $("input").kendoNumericTextBox();

    //wire focus of all numerictextbox widgets on the page
    $("input[type=text]").on("focus", function () {
        var input = $(this);
            clearTimeout(input.data("selectTimeId")); //stop started time out if any

            var selectTimeId = setTimeout(function()  {
                input.select();
                // To make this work on iOS, too, replace the above line with the following one. Discussed in https://stackoverflow.com/q/3272089
                // input[0].setSelectionRange(0, 9999);
            });

            input.data("selectTimeId", selectTimeId);
        }).blur(function(e) {
            clearTimeout($(this).data("selectTimeId")); //stop started timeout
        });
    })
</script>
