Yet another html numeric input, hope it's awesome

A textbox only allows visitor to type numeric, dot, and minus sign. This will replace the half-ass HTML5 input type=number.

• Allow positive and negative number
• Allow decimal number (with default decimalSeparator is the dot)
• While user typing, it will remove all decimalSeparator that have other decimalSeparator following. After this processing, only the last decimalSeparator is kept.
• This is vanilla JS, no other library required
• Tested on Chrome, Firefox, IE10, IE11
• Tested on Windows, the keycodes is taken from http://keycode.info

What do I provide?

This is just a JS function toHtmlNumericInput(string, bool). Copy it to your page and that's all.

How to use

Call toHtmlNumericInput('num'); // by default, DOT is the decimalSeparator, you can type "123456.789" Call toHtmlNumericInput('num', true); // if you want to use COMMA as decimalSeparator, you can type "123456,789"
