我正在尝试检查if a paragraph (excluding any nested child tags) contain text-但是现在它的缩进会产生误报-那么人们如何使用$.trim()摆脱它们?

HTML:

<div>
    <p>
      <a>Should not react to this</a>
    </p>
</div>


JS:

if($('p').clone().children().remove().end().text()) {
  console.log('WRONG! Paragraph does not have any text');
}

最佳答案

将您的字符串传递给$.trim

if(! $.trim($('p').clone().children().remove().end().text())) {
    alert('WRONG! Paragraph does not have any text');
}
