The Jquery code below works very well and checks for input values based on conditions .. But for the ESNList text field in the HTML form , many ESNs(numbers) can be entered and separated by a comma in the same text field , how can I make so Jquery makes sure that all the numbers entered on the same text field still match the condition for ESNList , your help would be greatly appreciated ..

 <html>
    <head>
    <script type="text/javascript" src="jquery/jquery-1.8.3.js"></script>
    <script type="text/javascript">

    $(function () {


    $(":text").css("border", "2px solid red");
      $(":text").keyup(function(){
        var enteredData = $(this).val()
        console.log(enteredData);
        if (enteredData == "") {
          $(this).css("border", "2px solid red");
        } else {
          $(this).css("border", "inherit");
        }
        if ($(this).attr("id") == "ESNList"){
          esnList = parseInt(enteredData);
          switch (true){
            case ( esnList >= 986329 && esnList <= 999999):

You can split the list by a comma delimiter and validate each individual element.

$.each(enteredData.split(","), function(i, str){
    var esnList = +str;
    /* enter validation here */
});
