How to track event to add text to the input?

Create a form, it is necessary that when entering text in input is triggered a function, that when you enter, if you remove text, no action should occur. How it can be implemented? Thanks in advance for your help.

if you remove text, no action should happen

that is, do not delete the text, or what?

Maybe try:

$( ".target" ).change(function() {
//
});

so, in principle, to increase the number of characters

var start_length = $( ".target" ).val().length;
$( ".target" ).keyup(function() {
 if($( ".target" ).val().length > start_lenght) {
 start_length = $( ".target" ).val().length;
 alert('added text');
}
});
