jQuery - setInterval doesnt work

I'm trying to code a little Homepage with jQuery. It has a form and I want to check something with jQuery.

I have a textbox with the id points. jQuery has following code:

$(document).ready(function() {
  setInterval(function() {
    if ($("#points").value().length > 500) {
      alert("Too many points!");
    }}, 100)
});

But it doesn't work. Can someone help me?

I see two problems:

  1. There is no function called value() in jQuery. It's val(). For JavaScript, It is .value.

  2. You are trying to get the length of the number, which will give you 3 if the number was 123.

    $(document).ready(function() {
  setInterval(function() {
    if ($("#points").val() > 500) {
      alert("Too many points!");
    }
  }, 100);
});
