在多行中查找并加入行

Question

我想选择以handleSubmit(event) { event.preventDefault(); let target = event.target; let formData = {}; for (let i = 0; i < target.length; i++) { formData[target.elements[i].getAttribute("name")] = target.elements[i].value; } console.log('formData', formData); } 和<h2>结尾的行，并希望如下所示合并这些行：

现有文本：

</h2>

所需文本：

<h2>

</h2>

<h2>
A zombie hare chest tattoo
</h2>

You won’ tsee this tattoo every day.

<h2>
Abby Name Tattoos
</h2>

For your little angels, a tattoo of their names will never be a mistake.

我正在使用RegEx <h2> A musician's tattoo </h2> If you’ re a musician and would like tolket a tattoo, get a tattoo of your ... <h2> A zombie hare chest tattoo </h2> 100/lO0.002.jpg You won’ tsee this tattoo every day. <h2> Abby Name Tattoos </h2> For your little angels, a tattoo of their names will never be a mistake. ，但只标记了一行。

Answer 1

• Ctrl + H
• 查找内容：(<h2>)\R(.+)\R(.+)
• 替换为：\1\2\3
• 检查环绕
• 检查正则表达式
• 全部替换

说明：

(<h2>)  : <h2> into group 1
\R      : any kind of linebreak
(.+)    : matches any character into group 2 (except for line terminators)
\R      : any kind of linebreak 
(.+)    : matches any character into group 3 (except for line terminators)

如果您确实要在H2文本之前和之后插入空格，则必须在“替换为”中的\2之前和之后插入空格。对于干净的HTML，这没有任何意义。
