ActiveForm beforeSubmit用法

$("#login-form").on("beforeSubmit", function (event) {  // Now you can work with messages by accessing messages variable  var attributes = $(this).data().attributes; // to get the list of attributes that has been passed in attributes property  var settings = $(this).data().settings; // to get the settings});

beforeValidate,afterValidate,beforeSubmit,ajaxBeforeSend,ajaxComplete以上有5个都可以用同样的写法来捕获事件，具体参数参考activeform.js
