min and max jQuery character counter

There are many max cha开发者_JAVA百科racter counters in jQuery.

Has anyone found any useful min character counters?

I'm looking for something like what StackOverflow uses when creating a comment:

This should work:

var min = 15;
$("#idOfTextbox").keydown(function() {
    if(this.value.length < min) {
        // Min notice
    } else {
        // Current count
    }
});
