comparing dates

[akshaj nampelly]

I have 2 dates A, B.

I get date A displayed on the form and on which I have to enter date B. The condition here is date B should be always later than date A. If user enters prior date in date B Text box and submits, an alert message have to be prompted to correct it. I want to use javascript logic for this.

code snippets please.

<script type="text/javascript">
  function Validate(){
    var d1 = new Date(document.formName.startName.value);
    var d2 = new Date(document.formName.endName.value);
    if(d2<=d1){
      alert('Wrong');
      return false
    }
    return true;
  }
</script>

the form

<form name="formName" onsubmit="return Validate()">

I dont want to put with <form tag>. But with submit button I want to validate the two dates.

date A property is already displayed on page. date B will be entered and validated to be prior to date A. date A and B are two properties in a single form.

suggest on this.

putting the onsubmit handler causes the validatin to occur when the submit button is pressed.

I gave you the basic example for the code. If the date A is hard-coded to the page, then hard-code it into the JavaScript function.
