如何将一个技巧的长标签分成多行？

.long-label {
  word-wrap: break-word;
}

.long-label {
  white-space: pre-wrap;
}

.long-label {
  max-width: 200px;
  overflow: hidden;
  text-overflow: ellipsis;
}

const label = document.querySelector('.long-label');
const maxWidth = 200; // 指定最大宽度
const words = label.textContent.split(' ');
let line = '';
let lines = [];

words.forEach(word => {
  const testLine = line + word + ' ';
  const testWidth = label.getBoundingClientRect().width;
  if (testWidth > maxWidth && line !== '') {
    lines.push(line);
    line = word + ' ';
  } else {
    line = testLine;
  }
});

lines.push(line);
label.textContent = lines.join('\n');
