ASP.NET - Javascript to validate text boxes

I have an ASP.NET app using masterpages - I've attached a sample of the code.  I tried using the Validate controls with .NET but don't like how they are working so I want to implement javascript to perform the validations.

1.  Need to ensure that no text boxes are empty
2.  NewPassword and ConfirmPassword match
3.  OldPassword matches OrigPassword (I also have this in a session).

Any ideas?

CASE 1 : make sure that no textbox should be empty .
CASE 2 :  NewPassword and ConfirmPassword match

you can try this

$(".submitButton").click(function() {
  var isValid = true;
$.each($("input[type=text]"),function() {
     if($(this).val() == "")
    {
     alert("No text box can be empty");
     $(this).focus();
     isValid =false;
    }
    if(!isValid ) return false;
});
 if(isValid)
 {
    if($("#txtNewPwd").val() != $("#txtConfirmPwd").val())
    {
           alert("New Password and Confirm Password must match.");
           isValid = false;
    }
 }
  return isValid
});



CASE 3 :  OldPassword matches OrigPassword (I also have this in a session).

For this,you have to make an jQuery ajax call to ther server to validate by comparing the oldpassword from the password stored in the session,as session will not be accessible to the client code (i.e jquery),So you have to go to the server by doing asynchronus call i.e Ajax call.

Code is not working.  I receive $ is not defined.

<script type="text/javascript">

$(".submitButton").click(function() {
  var isValid = true;
$.each($("input[type=text]"),function() {
     if($(this).val() == "")
    {
     alert("No text box can be empty");
     $(this).focus();
     isValid =false;
    }
    if(!isValid ) return false;
});
 if(isValid)
 {
    if($("#txtNewPwd").val() != $("#txtConfirmPwd").val())
    {
           alert("New Password and Confirm Password must match.");
           isValid = false;
    }
 }
  return isValid
});

</script>

you need to add the Jquery reference on the head section of your page. Just add the line

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

in the head section of the page.

OR
you can also get the local copy of jquery from the jquery.com site.

Both of them will work.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js">

$(".submitButton").click(function() {
  var isValid = true;
$.each($("input[type=text]"),function() {
     if($(this).val() == "")
    {
     alert("No text box can be empty");
     $(this).focus();
     isValid =false;
    }
    if(!isValid ) return false;
});
 if(isValid)
 {
    if($("#txtNewPwd").val() != $("#txtConfirmPwd").val())
    {
           alert("New Password and Confirm Password must match.");
           isValid = false;
    }
 }
  return isValid
});

</script>

I'm using master pages - I can't put it in the head section of my page as the page does not have a head section.

Please look at the document that I attached with my posting.

Ok  you can place  the following line (script> in the Head section of your Master Page. It will have no issue.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js">

Lalit ChandraCommented:
yes,in your page (content page),
place the following line anywhere in your page.

<script Language="Javascript">
    $(function() {

$(".submitButton").click(function() {
  var isValid = true;
$.each($("input[type=text]"),function() {
     if($(this).val() == "")
    {
     alert("No text box can be empty");
     $(this).focus();
     isValid =false;
    }
    if(!isValid ) return false;
});
 if(isValid)
 {
    if($("#txtNewPwd").val() != $("#txtConfirmPwd").val())
    {
           alert("New Password and Confirm Password must match.");
           isValid = false;
    }
 }
  return isValid
});


    });
</script>
