如何使用jquery validation equalTo方法的變量？

Question

我想用jquery validation equalTo方法使用變量。但不適用於jquery選擇器。我怎樣才能做到這一點？

HTML

<form id="form" method="post"> 
    <div> 
     <input type="password" name="pass1" id="passM" required /> 
    </div> 
    <div> 
     <input type="password" name="pass2" id="passR" required /> 
    </div> 
    <button type="submit">Submit</button> 
</form> 

JS

var form = $('#form'), 
    el1 = '#'+form.find('#passM').attr('id'), 
    el2 = form.find('#passR').attr('name'); 


form.validate({ 

    rules: { 

      el2: { 
      equalTo: el1 
     } 
    } 
}) 

Code example

將這項工作？

var form = $('#form'), 
    el1 = '#'+form.find('#passM').attr('id'), 
    el2 = form.find('#passR').attr('name'); 

var r = {}; 
r[el2] = { equalTo: el1 }; 

form.validate({ 
    rules: r 
});
