我现在正在使用Gmail扩展程序,并且鉴于我拥有父元素,并且它看起来类似于下图,因此我需要删除<br clear="all" />
之后的所有内容,因为之后可能有无根据用户的Gmail签名设置存在。有想法吗?
<div
id=":93"
class="Am Al editable LW-avf"
hidefocus="true"
aria-label="Message Body"
g_editable="true"
role="textbox"
aria-multiline="true"
contenteditable="true"
tabindex="1"
style="direction: ltr; min-height: 416px;">
Test
<br clear="all" />
<div>
<br />
</div>
-- <br />
<div dir="ltr" class="m_-1358982132021700848m_4914548661371847332gmail_signature" data-smartmail="gmail_signature">
<div dir="ltr">
<b>Suzy Smith</b>
<div>
<i><a href="mailto:suzysmith@mail.com" target="_blank">suzysmith@mail.com</a></i>
</div>
</div>

只需遍历nextSibling并将其删除。
var elem = document.querySelector('[clear="all"]')
while(elem.nextSibling) {
elem.nextSibling.remove()
}
elem.remove()
