}`

并将其更改为：

<label>Some text here</label>

我尝试使用此代码：

<label>Some<br>text<br>here</label>

但它没有用。

Answer 1

使用html()方法和回调函数。并且用String#replace方法替换所有空间使用正则表达式与全局falg。

＆＃13;

$('label').html(function(i, oldHTML) {
  return oldHTML.replace(/\s+/g, '<br>');
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>Some text here</label>

＆＃13;

Answer 2

你必须设置html，这可能会起作用：

$('.form-group label').html($('.form-group label').html().replace(' ', '<br>'));

如何用<br/>标签替换标签标签中的空格？
