You can use regular expression for this. Just use the below function:

function checkEmail($email) {
  if(preg_match("/^([a-zA-Z0-9\._-])*@abc.com$/",$email)){

    return true;
  }
  return false;
}

Code Edited

    <script type="text/javascript">
    function validateEmail(elementValue){  
       var emailPattern = /^[a-zA-Z0-9._-]+@abc.com$/;  
       return emailPattern.test(elementValue);  
     }  

    function checkForm(){
        var emailId = document.getElementById('email_address').value;
        if(! validateEmail(emailId)) {
            alert("Email id is not valid");
        }
    }
</script>

<div class="input-box"style="width: 550px;"> 
    <input type="text" name="email" id="email_address" value="<?php echo $this->htmlEscape($this->getFormData()->getEmail()) ?>" title="<?php echo $this->__('Email Address') ?>" class="input-text validate-email required-entry" /> 

    <input type="submit" value="Click here" onclick="checkForm()" />(There will be be an submit button put the onclick event in it)

</div>
