Use userAgent to determine whether the string returned by userAgent contains "Chrome". How can this problem be detected through the indexOf method. The Code is as follows: <script type = "text/javascript"> var isChrome = window. navigator. userAgent. indexOf ("Chrome ")! =-1; alert (isChrome); if (isChrome) {alert ("Chrome browser");} else {alert ("not Chrome browser ");} </script> about the indexOf method: the indexOf method returns an integer indicating the starting position of the substring in the String object. That is, the position of the character contained in indexOf () in the string. The number of characters returned in the nth digit starts from 0. If repeated characters appear, the first character shall prevail. If no substring is found,-1 is returned.
