regex - HTML5 Form Input Pattern Currency Format -

using html5 have input field should validate against dollar amount entered. have following markup:

<input type="number" pattern="(\d{3})([\.])(\d{2})"> 

this works great amount greater 100.00 , less 1,000.00. trying write pattern (regex) accept amount less dollar , greater dollar. maybe upwards of 100,000.00. possible?

any appreciated! :)

if want allow comma delimiter pass following test cases:

0,00  => true 0.00  => true 01,00 => true 01.00 => true 0.000 => false 0-01  => false 

then use this:

^\d+(\.|\,)\d{2}$
