原标题:Select all elements that are not descendents of elements with a certain class

I m trying to come up with a selector that will select all textarea elements, except those that are descendents of the .noSpell class.

因此,我希望这样做:

<div>
   <textarea />
</div>

而不是

<div class="noSpell">
   <div>
      <textarea />
   </div>
</div>

I tried this:

$(":not(.noSpell) textarea")

but it didn t work, presumably because while it won t match the outer element, it can match any of the inner ones.

So, how would I write a selector that excludes parts of the DOM tree based on a class name?

最佳回答

如何做到这一点:

$("textarea").not(".noSpell textarea")

随后,所有文本都删除了有<代码>的母体。

问题回答

以下是我的工作:

$("textarea").not(".noSpell");

在火./火力燃烧中测试。

@cdmckay 你的方法也是正确的。

起草案文如下:

<textarea></textarea> 

并且看您的法典是否可行。

你们也许希望这样做,看看你们的法典是否可行。

if($(":not(.noSpell) textarea").length > 0) {
    alert("there");
}
else {
    alert("not there");
}

Cheers!
