validating only few fields for any specific submit button

I am using jQuery Validation plugin ( http://bassistance.de/jquery-plugins/jquery-plugin-validation/ )

I have a very odd scenario in front of me.

I have one form, with 5 different submit buttons

<form id="frm1" name="frm1" method="post" action="save.ph开发者_如何转开发p">
  ------- input fields here---
  <input type="submit" name="submit" value="update account info">

  ------- input fields here---
  <input type="submit" name="submit" value="update address info">

  ------- input fields here---
  <input type="submit" name="submit" value="update credit-card info">

  ------- input fields here---
  <input type="submit" name="submit" value="update bank info">

  ------- input fields here---
  <input type="submit" name="submit" value="update other info">
</form>

Now, for each submit button, I need to validate a few fields (and not all fields)

Say for "update account info" submit, I need to validate following input fields with following ids:

 cust_fname
 cust_lname
 cust_age

Say for "update other info" submit, I need to validate following input fields with following ids:

 married
 childerns

How can I achieve following?

create 5 separate forms is the most easy way to do this. Then you can bind a different specific validation to each form.

Or you can bind a validation to each click on a submit button. assuming you update your submitbutton to:

  <input type="submit" id="button_1" name="submit" value="update account info">

Then with jquery you can bind this with:

$("#button_1").live("click", function() {
    $("#frm1").validate({
        rules: {
            cust_fname: "required", // of course set different options for every field
            cust_lname: "required", 
            cust_age: "required"
        }
    }); 
});

And do this for every button.

edit: Live has been deprecated.

$("#button_1").on("click", function() {
    $("#frm1").validate({
        rules: {
            cust_fname: "required", // of course set different options for every field
            cust_lname: "required", 
            cust_age: "required"
        }
    }); 
});
