使用jQuery将表单数据抓取到对象中，以生成任意数组和对象的值

var formData = {};

var formArray = $('form').serializeArray();

$.each(formArray, function(index, field){
  formData[field.name] = field.value;
});

var serializedData = $('form').serialize();

var dataArray = serializedData.split('&');

var formData = {};
$.each(dataArray, function(index, data){
  var pair = data.split('=');
  formData[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
});
