jquery方法.serializeArray()获取name和value并转为json数组

[ 
  {name: 'firstname', value: 'Hello'}, 
  {name: 'lastname', value: 'World'},
]

var m = {};
$.each($("form").serializeArray(), function(i, field){
      m[field.name]=field.value;
});

var m = {};
        $.each($(v).find(".panel-body form").serializeArray(), function(i, field){
            if(!m.hasOwnProperty(field.name)){
                m[field.name]=[];
            }
            m[field.name].push(field.value)
        });
