A simple jQuery plug-in which sets an (input) element to only allow numbers.
allowFloat: (boolean) Allows floating point numbers to be entered. Default: false.
allowNegative: (boolean) Allows negative numbers to be entered. Default: false.
min: (number) The minimum value that can be entered into the textbox, if set to null any number is valid. Default: null
max: (number) The maximum value that can be entered into the textbox, if set to null any number is valid. Default: null
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 });
