如何使用jQuery从dom中删除空元素?
问题描述：
WordPress单词编辑器会吐出空的<p>标记，如下所示:<p> </p>.
The WordPress word editor spits out empty <p> tags like this: <p> </p>.
我想将其中所有带有 的<p>定位为目标并将其删除.我相信我必须使用contains和remove函数，但是我不确定该代码是否删除仅包含 的<p>标签或删除其中包含 的所有<p>标签任何地方.
I would like to target all <p> with in them and remove them. I believe I have to use the contains and remove functions but I am not sure if this code would remove the <p> tags with only in them or remove all <p> tags with in them anywhere.
jQuery('p:contains(" ")').remove();
我将如何进行这项工作?
How would I make this work?

，您可以使用 .filter 并查看innerHTML是否为等于 :
you can use .filter and look if the innerHTML is equal to :
$("p").filter(function(){
return $.trim(this.innerHTML) === " "
}).remove();
