PRB: Parseint Returns 0 for Some Strings with Leading Zeros (191434)

RESOLUTION

You must remove the leading zeros before calling parseInt. Here is the code for the workaround:

function parseVal(val)
{
   while (val.charAt(0) == '0')
      val = val.substring(1, val.length);

   return val;
}

Steps to Reproduce Behavior

The following Web page demonstrates this problem. This Web page contains a text box. When focus is shifted away from the edit box by pressing the TAB key, the parseInt() function is called with the value that was entered into the text box. The value returned from parseInt() is then displayed in an alert box. If you enter "08" or "09" into the text box, parseInt() returns a value of 0.
