返回值:Array<Object>serializeArray()

V1.2概述

序列化表格元素 (类似 '.serialize()' 方法) 返回 JSON 数据结构数据。

'''注意''',此方法返回的是JSON对象而非JSON字符串。需要使用插件或者第三方库进行字符串化操作。

返回的JSON对象是由一个对象数组组成的,其中每个对象包含一个或两个名值对——name参数和value参数(如果value不为空的话)。举例来说:

 [ 
     {name: 'firstname', value: 'Hello'}, 
     {name: 'lastname', value: 'World'},
     {name: 'alias'}, // this one was empty
  ]

示例

描述:

取得表单内容并插入到网页中。

HTML 代码:
<p id="results"><b>Results:</b> </p>
<form>
  <select name="single">
    <option>Single</option>
    <option>Single2</option>
  </select>
  <select name="multiple" multiple="multiple">
    <option selected="selected">Multiple</option>
    <option>Multiple2</option>
    <option selected="selected">Multiple3</option>
  </select><br/>
  <input type="checkbox" name="check" value="check1"/> check1
  <input type="checkbox" name="check" value="check2" checked="checked"/> check2
  <input type="radio" name="radio" value="radio1" checked="checked"/> radio1
  <input type="radio" name="radio" value="radio2"/> radio2
</form>
jQuery 代码:
var fields = $("select, :radio").serializeArray();
jQuery.each( fields, function(i, field){
  $("#results").append(field.value + " ");
});
