HTML5 Form Input Pattern Currency Format

Question

Using HTML5 I have an input field that should validate against a dollar amount entered  Currently I have the following markup    lt input type  number  pattern    d 3          d 2    gt    This works great for an amount that is greater than 100 00 and less than 1 000 00  I am trying to write the pattern  regex  to accept different dollar amounts  Maybe upwards of 100 000 00  Is this possible

Another answer for this would be      d     d 1 3      d 3         d 2       This will match a string of    one or more numbers with out the decimal place   d   any number of commas each of which must be followed by 3 numbers and have upto 3 numbers before it   d 1 3      d 3       Each or which can have a decimal place which must be followed by 2 numbers    d 2

How about       d    d 2     This matches one or more digits  a dot and 2 digits after the dot   To match also comma as thousands delimiter      d      d 3      d 2

I like to give the users a bit of flexibility and trust  that they will get the format right  but I do want to enforce only digits and two decimals for currency      - s    d           d 0 2    s     Takes care of     1  -  1 00   -1 0  1  10 -  1 000 000 0   Of course it will also match     -- 1 92 9 29 1   gt  anyway after cleanup   gt  -192 929 10

The best we could come up with is this           1-9    d    d 0 2     d 3      0       d 1 2      I realize it might seem too much  but as far as I can test it matches anything that a human eye would accept as valid currency value and weeds out everything else    It matches these   1   gt  true 1 00   gt  true  1   gt  true  1000   gt  true 0 1   gt  true 1 000 00   gt  true  1 000 000   gt  true 5678   gt  true   And weeds out these   1 001   gt  false 02 0   gt  false 22 42   gt  false 001   gt  false 192 168 1 2   gt  false     gt  false  55   gt  false 2000 000   gt  false

If you want to allow a comma delimiter which will pass the following test cases   0 00    gt  true 0 00    gt  true 01 00   gt  true 01 00   gt  true 0 000   gt  false 0-01    gt  false   then use this     d         d 2
