Answer 1

<script>
  $("#ed_endtimedate").change(function() {
    var startDate = document.getElementById("ed_starttimedate").value;
    var endDate = document.getElementById("ed_endtimedate").value;

    if ((Date.parse(endDate) <= Date.parse(startDate))) {
      alert("End date should be greater than Start date");
      document.getElementById("ed_endtimedate").value = "";
    }
  });
</script>

Answer 2

在你的提交按钮上试试这个。

function validateForm() {

    var startDate = document.getElementById("startDate").value;
    var endDate = document.getElementById("endDate").value;
    var x = new Date(startDate);
    var y = new Date(endDate);

    if (x > y) {
        alert("Start date must be less than end date!");
        document.getElementById("endDate").value="";
        return false;
    }
}
