<code>.serializeArray()</code>方法使用标准的W3C<a href="http://www.w3.org/TR/html401/interact/forms.html#h-17.13.2">"successful controls"</a>的标准来检测哪些元素应当包括在内。被禁用的元素不会被包括在内。并且,元素必须含有 <code>name</code> 属性。此外，提交按钮的值也不会被序列化。文件选择元素的数据也不会被序列化。</p>
|
||
<p><code>.serializeArray()</code> 方法可以对单独选择的表单元素对象进行操作， 比如 <code><input></code>, <code><textarea></code>, 和 <code><select></code>。还有个更方便的方法是，直接使用 <code><form></code> 标签来进行序列化操作：</p>
