如何确保滚动后整个选项卡可见？

.tab-container {
  overflow: auto;
}

function ensureTabVisible(tabId) {
  var tabContainer = document.getElementById('tab-container');
  var tab = document.getElementById(tabId);
  
  var containerRect = tabContainer.getBoundingClientRect();
  var tabRect = tab.getBoundingClientRect();
  
  if (tabRect.left < containerRect.left) {
    tabContainer.scrollLeft -= containerRect.left - tabRect.left;
  } else if (tabRect.right > containerRect.right) {
    tabContainer.scrollLeft += tabRect.right - containerRect.right;
  }
}
