HTMLInputElement.setSelectionRange

The HTMLInputElement.setSelectionRange() method sets the start and end positions of the current text selection in an <input> element.

Optionally, in newer browser versions, you can specify the direction in which selection should be considered to have occurred; this lets you indicate, for example, that the selection as set by the user clicking and dragging from the end of the selected text toward the beginning.

This method updates HTMLInputElement.selectionStart, selectionEnd, and selectionDirection in one call.

Syntax

inputElement.setSelectionRange(selectionStart, selectionEnd[, selectionDirection]);

Parameters

selectionStart: The 0-based index of the first selected character.
selectionEnd: The 0-based index of the character after the last selected character.
selectionDirection Optional: A string indicating the direction in which the selection is performed. This string can be "forward" or "backward", or "none" if the direction is unknown or irrelevant.

The following code:

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>
<title>JS Bin</title>
<script>
function SelectText () {
        var input = document.getElementById("mytextbox");
