max: (number) The maximum value that can be entered into the textbox, if set to null any number is valid. Default: null

Usage

Given the following input element <input id="elementID" type="text" />

To create an input element which only accepts positive integers simple use the .numericInput() function.

<script type="text/javascript" src="../numericInput.min.js"></script>
<script>
	$(function() {
		$("#elementID").numericInput();
	});
</script>

To create an input element which accepts positive or negative integer set the allowNegative option to true

$("#elementID").numericInput({ allowNegative: true });

To create an input element which accepts positive numbers (floating point) set the allowFloat option to true

$("#elementID").numericInput({ allowFloat: true });

To create an input element which accepts any number (positive or negative floating point) set both allowFloat and allowNegative to true

$("#elementID").numericInput({ allowFloat: true, allowNegative: true });
