<h3>Additional Notes:</h3>
|
|
<div class="longdesc"><ul><li>
|
|
因为 <code>[name!="value"]</code> 是一个 jQuery 延伸出来的一个选择器。 并且不是的CSS规范的一部分, 使用<code>[name!="value"]</code>查询不能充分利用原生DOM提供的<code>querySelectorAll()</code>方法来提高性能。为了在现代浏览器上获得更佳的性能，请使用<code>$("your-pure-css-selector").not('[name="value"]')</code> 代替。
