This is not exactly right. If you are going to provide free text entry in the nox, there is no way to accurately detect how many customers were entered in the box.

If these customers are to be selected from a database, provide a list view rather than a drop down so that user can select customers directly.

Alternately, just provide three text boxes with maxlength[^] defined on each so that user enters names with restricted length.

Do you want to allow user to enter customer details in the text box with any separator?
If yes then use below code to disable text box.

$(document).ready(
function(){
	$('#userInput').bind('input', function(){
   var users = $("#userInput").val();
   var usersList = users.split(';');
   //disable if users count is > 3
   if(usersList.length > 3){
   $('#userInput').prop('disabled','disabled')
   }
});

}
)
