Answer 1

Why not work with substr ?为什么不使用substr ？

 let text = document.querySelector('.tracktime').textContent.trim().substr(0, 5); console.log(text);

 <span class="tracktime">06:21 - 15.26 mb</span>

If all you want to achieve is replacing the new line, go like this:如果您想要实现的只是更换新线 go ，如下所示：

 let text = document.querySelector('.tracktime').textContent.trim().replaceAll('\n', ''); console.log(text);

 <span class="tracktime">06:21 - 15.26 mb</span>
