Oct 29, 2010

## Use A Function To Format The Number In The "Amount Received" Text Box?

Jul 9, 2010

Hi All, I am trying to program a web based cash register/POS application. I would like to use a function to format the number in the "Amount Received" text box.For Example: if someone typed in 2000 it would automatically change that to 20.00

I would probably be triggering the function via onkeyup so it would actually change it on number at a time. 2->.02, 20->.20, 200->2.00, 2000->20.00 ect.I know I could do it in php when processing the form, but I would really like the number to be already formatted when the form is submitted.

## Converting Number To Date Format?

Jan 20, 2011

how to approach this but I have a date input that uses a jQuery pop-up for a calendar, and enters the date in a format d MMM yy (1 Jan 11).

Not everyone wants to be clicking and choosing the date from the calendar but to be entering it just as a number such as 0101, 010111 or 01012011 which can be faster. This would then need to be converted to the d MMM yy format as per the jQuery pop-up when they exit the input box.

So really only if it's a number format it needs to look at the number of digits... and does the conversion.

Has anyone done something like this before? Or is there a link to how I could go about achieving this?
