js判断ios版本是否是13.4.几的

方法一：

const isIOS13_4 = () => {
  const ua = navigator.userAgent;
  const iosVersion = parseFloat(
    ('' + (/CPU.*OS ([0-9_]{1,5})|(CPU like).*AppleWebKit.*Mobile/i.exec(ua) || [0, ''])[1])
      .replace('undefined', '3_2').replace('_', '.').replace('_', '')
  );
  return iosVersion === 13.4;
}

console.log(isIOS13_4()); // true or false

方法二：

const isIOS13_4 = () => {
  const iosVersion = parseFloat(('' + (navigator.userAgent.match(/OS (\d+)_(\d+)_?(\d+)?/) || [0, 0, 0])[1] + '.' + (navigator.userAgent.match(/OS (\d+)_(\d+)_?(\d+)?/) || [0, 0, 0])[2]).replace(/\b0+/g, ''));
  return iosVersion === 13.4;
}

console.log(isIOS13_4()); // true or false

js判断ios版本是否是13的

方法如下：

const isIos13 = () => {
  const ua = navigator.userAgent;
  const match = ua.match(/OS (\d+)_(\d+)_?(\d+)?/);
  if (match !== null) {
    const version = parseInt(match[1], 10);
    return version === 13;
  }
  return false;
};

使用方式：

if (isIos13()) {
  // iOS 13 特定的代码逻辑
}
