jQuery detect if string contains something

I'm trying to write jQuery code to detect if a live string contains a specific set of characters then the string alerts me.

HTML

<textarea class="type"></textarea>

My Jquery

$('.type').keyup(function() {
    var v = $('.type').val();
    if ($('.type').is(":contains('> <')")){
        console.log('contains > <');        
    }
    console.log($('.type').val());
});

if for example I typed the following

> <a href="http://google.com">Google</a> <a href="http://yahoo.com">Yahoo</a>

My code should console log alert me that there > < present in the string.
