Date problems in Safari Browser only

[ipy2006]

Only in Safari browser the current year shows as 1970. Also "Non digits
found in year" is triggered in the Safari broswer. Please help.
Thanks,

function verifyYear( field )
{
var _x = field.value;

var _exp = new RegExp(/^\d+$/);
var _test=_exp.test(_x);

var _currentDate = new Date();

var yy = _currentDate.getUTCFullYear();

alert("entered year is : " + _x + " current year is : " + yy );

if(_x.length!=4) {
alert("Please enter four digit year.");
return false;
}
else if(!_test) {
alert("Non digits found in year.");
return false;
}
else if( _x > yy ) {
alert("You entered a year in the future. Please enter valid year."
);
return false;
}
else {
return true;
}

}

I don't know Safari,
but .getUTCFullYear() should be valid from Safari 1.2.


You make a rather complex code,
with al those spurious "else" clauses after a return.
[Please do not use tab chars in a code on usenet]
try:


function verifyYear( field ) {
var x = field.value;
var y = new Date().getUTCFullYear();
alert("entered year is : " + x + " current year is : " + y );

if( x.length != 4 ) {
alert("Please enter four digit year.");
return false;
};

if(/[^\d]/.test(x)) {
alert("Non digits found in year.");
return false;
};

if( x > y ) {
alert("You entered a year in the future. Please enter valid year.");
return false;
};

return true;
}

Only in Safari browser the current year shows as 1970.

Then you should alert(_currentDate) to see what you are getting.

Also "Non digits
found in year" is triggered in the Safari broswer.

Then you should alert(_x) to see what you are getting.

function verifyYear( field )
{
var _x = field.value;

var _exp = new RegExp(/^\d+$/);

or. reversing logic, /\D/

var _test=_exp.test(_x);

var _currentDate = new Date();

var yy = _currentDate.getUTCFullYear();

alert("entered year is : " + _x + " current year is : " + yy );

Entered year is by local civil time. Current year is UTC. They should,
generally, not be compared.

if(_x.length!=4) {
alert("Please enter four digit year.");
return false;
}
else if(!_test) {
alert("Non digits found in year.");
return false;
}
else if( _x > yy ) {
alert("You entered a year in the future. Please enter valid year."
);
return false;
}
else {
return true;
}

}

An "else" is nor needed after "if ... return ...".
