So you check the value before you send through AJAX.

$('input#mybutton').click(function() {
    var text = $('textarea#mytextarea').val();
    // Validate the text HERE
    $.ajax({
        type:     "GET",
        url:      pURL,
        async:    false,
        dataType: "html",
        success: function(pReturn) {
            // Process the return.
        }
    });
});

The <textarea> tag is not allowed outside a <form>. What you're proposing wouldn't pass an HTML validator. Just surround your <textarea> with a <form>.

Why not just validate it yourself. If there is certain requirements that you want to check, before the submission, or attach an onblur event to the textarea and you can ensure that the data is correct.

I would opt for the onblur event as that would enable you to let the user know quickly if there is a problem.
