Select All Text on Focus

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>
