alert err_str at the end of the function

PS. /^(\d|[01]\d|2[0-3])[:.] [0-5]\d$/

[narinas]

no im not getting it

[javaranjith]

Instead of using this code (alert(err_str) ;) in all loop, move this at the end of the function.

i did it but is showing alert as undefined.

[Dormilich]

if there is no error (hence no error string) you must not use alert().

[narinas]

il get error msg when the validation is false so if all the indexes get errors error msg will display & i need all the msg's to be displayed in a single alert box.
