使用$ .getJSON以特定格式發送數據？

Question

$.getJSON('<?php echo $this->baseURL()?>/site/ajax/checkusername', 
    {username: $('#username').val()}, 
    function(data) 
    { 
     if (data == "TRUE") 
     { 
      $("#available").text("This username is available!"); 
     } 
     else 
     { 
      $("#available").text("This username is not available!"); 
     } 
    } 
    ); 

返回的請求URL：

http://my.local/site/ajax/checkusername?username=sdfsdf 

我想它的形式返回：

http://my.local/site/ajax/checkusername/username/sdfsdf 

如何才能實現這一目標？

$.getJSON('<?php echo $this->baseURL()?>/site/ajax/checkusername/username/' + encodeURIComponent($('#username').val()), 
    function(data) 
    { 
     if (data == "TRUE") 
     { 
      $("#available").text("This username is available!"); 
     } 
     else 
     { 
      $("#available").text("This username is not available!"); 
     } 
    } 
);
