如何通过表单发送javascript收集的数据

At now in view I have a ajax button and pass data like this

echo CHtml::ajaxButton(...,'js:$("#a").sortable("serialize")',..)

but how to pass this data with a form if i want to use form model?

jQuery is native to Yii, so for a start, use that.

Then just do something like (untested):

$('form').submit( function() {
  $.post('/url/', $(this).serialize()); 
});
