Validate Time

[LeahSmart]

Hi Reader!

I have a text field where a user enters a time in the format of hh:mm:ss, they can just enter hh:mm and it still works. Is there any way to validate this? So for example the user could not enter 99:99 which is not a valid time.

Any help would be great.

Thanks

Leah

Um... What if you check if the value is greater than 59 right before the focus on the textField goes away???

myText.onChange = function()
{
var _timeArr = this.text.split(":");
if (Number(_timeArr[0]) >= 24 || Number(_timeArr[1]) > 60 || Number(_timeArr[2]) > 60)
{
trace("invalid input~");
}
}

Black, that looks good. The only thing is if they do not enter a : or just generally are really stupid users and put the : in the wrong place. How about having two boxes, one for the hour and one for the minute? The the code above would work really well.

Textfield can restrict the user input...

Check out TextField.restrict and TextField.maxChars from the Flash manual for more information...

absolutely you can pick 3 boxes or just one, either will go well if we apply accurate code to it. and if you want to report an error if user forget to input an ":" or place it at wrong place just fix the if condition like this:

var _result = true;
if (_timeArr.length == 3 && !isNaN(_timeArr[0]) && !isNaN(_timeArr[1]) && !isNaN(_timeArr[2]))
{
if (Number(_timeArr[0]) >= 24 || Number(_timeArr[1]) > 60 || Number(_timeArr[2]) > 60)
{
_result = false;
}
}
else
{
_result = false;
}
if (!_result) trace("invalid input !");

hey CranBlue why you always post so fast ? i lose man...;):D

[CyanBlue]

That's because I don't give out the code like you do... :p Good job, man... :)

I have added the the code below to the onchange but it always says it's invalid even when it is not.


on (change){
var _result = true;
if (_timeArr.length == 3 && !isNaN(_timeArr[0]) && !isNaN(_timeArr[1]) && !isNaN(_timeArr[2]))
{
if (Number(_timeArr[0]) >= 24 || Number(_timeArr[1]) > 60 || Number(_timeArr[2]) > 60)
{
_result = false
}
}
else
{
_result = false;
}
if (!_result) trace("invalid input !");
if (_result) trace("valid input !");
}

i' sorry for missing something, try this:
if (_timeArr.length == 3 && !isNaN(Number(_timeArr[0])) && !isNaN(Number(_timeArr[1])) && !isNaN(Number(_timeArr[2])))

I entered 10:15 and it said it was invalid.

[black]

it will because it can only accept 3 parts: hours, minutes and seconds(you can see the code: _timeArr.length == 3) and if you want just 2 you can fix the number 3 to 2 and remove code: !isNaN(Number(_timeArr[2])) and its relation.
