Hi !
Who could help me with a javascript ?

What I need:

We have pages, where a user could input amounts.
These amounts could only be numbers (e.g. 100) with OR without an "M" (for million) or an "T" (for thousand):

e.g. 100 (hundred) , 100M (one hundred million), 100T (one hundred thousand) and so on.

- I need a validation script (which can be used for onKeyPress and onBlur) which ONLY accepts ".1234567890MT".

- This script has also to check whether the user puts in a "," . If so, the script has to replace this with an "."

- Only ONE "." is allowed, this means, if the user tries to put in: "100.000.000", the script should take out the last ".", because ONLY ONE "." is allowed.

-It should always capitalize the "m" or "t", whgen a user put that in. e.g. : 100m -> 100M

At least, there should be a parameter which thell the function, in the user is allowed to put in a NEGATIVE value or NOT.

e.g.: function_xy(notNegative)...

if notNegatibe == true -> no negative values are allowed, the script should also not allow to put in a "-" before the number, M or T is allowed

if notNegative == false -> the user could input 0-9, negative values are allowed, the user can put in a "-" before the number, M or T is allowed

The first function should be e.g. validOnKeyPress(notNegative);

The second function should be e.g. validFieldOnBlur(notNegative);

I hope, this is not to much :)

Could somebody help me here ?

This would be GREAT !!!

u should use RegularExpression to format ur Input Control & validate it. Check the MSDN for RegularExpression.

I used regualr expressions for something similar recently. Once you understand the basic rules its fairly simple but very powerfull.
