<p>如同其他伪类选择器（那些以“:”开始）建议前面加上一个标记名称或其他选择器;否则，通用选择("*")被默认使用。换句话说$(':disabled') 等同于 $('*:disabled')，所以应该使用$('input:checkbox')。 </p>
|
||
<p>虽然他们的选择的结果通常是一样的，<code>:disabled</code>选择器和<code>[disabled]</code> 属性（attribute） 选择器还是有些细微的差别；
|
||
<code>:disabled</code> 检查元素的disabled属性的布尔值（true/false），<code>[disabled]</code> 检查是否存在的disabled属性。</p>
|
||
<p><code>:disabled</code> 选择器仅可用于选择支持<code>disabled</code>属性（attribute）的HTML元素(<code><button></code>, <code><input></code>, <code><optgroup></code>, <code><option></code>, <code><select></code>, 和 <code><textarea></code>)。</p>
