Re: [flasher] VALIDATING INPUTTED TEXT

[Manuel S.-Harguindey]

Hello, this little code tests if string is a number and, if so, it

converts it to a two-decimal-digits number:


// put whatever as the string.

string = "3ytr4.665";

num = Number(string);

valid = !isNaN(string);

if (valid) {

   // converts to xxx.xx

   num = Math.floor(100*num)/100;

   trace (string+" is a valid number.... .Converted: "+num);

} else {

   trace (string+" is not a valid number.");

}


I dont know if it helps...

Manuel.
