I need to set a min length and a max length for my text area box on my website. I know for max i can do it in html, but min you cannot. Could someone help me with this? I can do if, else statements but that would be after the form is submitted. I want it to tell the user the length is too short before he/she even submits it. I think jquery would be the best but really unsure.

Set min-length
pattern=".5," --> 5 characters minimum
set both min-length and max-length
pattern=".5,100" --> 5 characters minimum and 100 maximum .
Example
<input type="text" name="test" pattern=".20,100" required >
to support Html5 in every browser use html5shiv
Updated after OP's comment
$('#myform').submit(function(e)
if($('#message').val().length < 3)
e.preventdefault();
);

Note that your HTML misses </head>. That said, the "pattern" attribute seems to work :
<input type="text" required="required" pattern="^[A-Za-z0-9]3,15$" />
Here is another way of doing this using Javascript. Just put this code into the <head> section, right after $("#datepicker").datepicker(); :
$('form').submit(function (e)
var nameValue = $('[name="name"]').val();
if (!/^[A-Za-z0-9]3,15$/.test(nameValue))
alert('failure');
e.preventDefault(); // prevents from submitting
);
Here is a demo combining both solutions : http://jsfiddle.net/wared/KbxM8/.
See also : http://api.jquery.com/submit/
I've tried something according to your comments :
$('form').submit(function (e)
var value;
// "message" pattern : from 3 to 15 alphanumerical chars
value = $('[name="message"]').val();
if (!/^[A-Za-z0-9]3,15$/.test(value.replace(/n/g, '')))
alert('Wrong value for "message".');
e.preventDefault();
return;
// "name" pattern : at least 1 digit
value = $('[name="name"]').val();
if (!/d+/.test(value))
alert('Wrong value for "name".');
e.preventDefault();
return;
);

hold on, I had it working, but now its not. I put [name="name"] as [name="message"] since the name of the text area is message.

Nope, still does not have an effect. I tried putting it in the header, and in the form, neither worked. I'll paste the updated code above, just so you can see what I am doing. Hmm, so weird

Here is a demo combining both solutions : http://jsfiddle.net/wared/KbxM8/.
See also : http://api.jquery.com/submit/
I've tried something according to your comments :
$('form').submit(function (e)
var value;
// "message" pattern : from 3 to 15 alphanumerical chars
value = $('[name="message"]').val();
if (!/^[A-Za-z0-9]3,15$/.test(value.replace(/n/g, '')))
alert('Wrong value for "message".');
e.preventDefault();
return;
// "name" pattern : at least 1 digit
value = $('[name="name"]').val();
if (!/d+/.test(value))
alert('Wrong value for "name".');
e.preventDefault();
return;
);

Worked great thank you! Now can I use some form of this to MAKE the user submit atleast 1 numeral in the username field?

hold on, I had it working, but now its not. I put [name="name"] as [name="message"] since the name of the text area is message.

I updated the code in the OP to show what I have, must just be a small error,
– Terry
Nov 2 '13 at 23:51
Nope, still does not have an effect. I tried putting it in the header, and in the form, neither worked. I'll paste the updated code above, just so you can see what I am doing. Hmm, so weird

Note that your HTML misses </head>. That said, the "pattern" attribute seems to work :
<input type="text" required="required" pattern="^[A-Za-z0-9]3,15$" />
Here is another way of doing this using Javascript. Just put this code into the <head> section, right after $("#datepicker").datepicker(); :
$('form').submit(function (e)
var nameValue = $('[name="name"]').val();
if (!/^[A-Za-z0-9]3,15$/.test(nameValue))
alert('failure');
e.preventDefault(); // prevents from submitting
);
