Account No. Validation.

function validation(){

var myReg = RegExp("^[0-9]{0,6}$");//this allows the account number of length 6

var m = myReg.exec(document.<formname>.<fieldname>);

//example:

//var m =myReg.exec(document.transaction.accountno);

if(m==null) {

alert("Invalid Account");

document.<formname>.<fieldname>.focus();

return false;

}

}

Serverside validation:

You can use java's regex feature or check the String class methods.

Hope you understand
