JAVASCRIPT中怎么判斷訪客終端是電腦還是手機

JAVASCRIPT中怎么判斷訪客終端是電腦還是手機，針對這個問題，這篇文章詳細介紹了相對應的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。

我們使用PHP的$_SERVER['HTTP_USER_AGENT']來獲取手機用戶瀏覽器的用戶代理，然后匹配已有的各種手機瀏覽器代理庫，如果含有匹配的關鍵字，則判斷為手機（移動終端）用戶。

function is_mobile() { $user_agent = $_SERVER['HTTP_USER_AGENT']; $mobile_agents = array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi",    "android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio",    "au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu",    "cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ",    "fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi",    "htc","huawei","hutchison","inno","ipad","ipaq","iphone","ipod","jbrowser","kddi",    "kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo",    "mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-",    "moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia",    "nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-",    "playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo",    "samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank",    "sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit",    "tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin",    "vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce",    "wireless","xda","xde","zte"); $is_mobile = false; foreach ($mobile_agents as $device) { if (stristr($user_agent, $device)) { $is_mobile = true; break; } } return $is_mobile; }

上述代碼中函數is_mobile()來判斷用戶終端類型，將收集到的當今各種手機的HTTP_USER_AGENT歸結到數組$mobile_agents中，并進行匹配。使用時只需調用函數is_mobile()。如以下代碼表示，當匹配用戶為手機訪問時，頁面跳轉到網站手機版m.xuebuyuan.com。

if (is_mobile()) { header('Location:http://m.xuebuyuan.com'); } else { echo '請使用手機訪問.'; }

Javascript版

您也可以直接在前端頁面上加入一段Javascript腳本來判斷用戶的終端類型。Javascript也是通過獲取瀏覽器的user-agent信息，然后匹配已有的user-agent信息庫。

if ((navigator.userAgent.match(/(iPhone|iPod|Android|ios|iOS|iPad|Backerry| WebOS|Symbian|Windows Phone|Phone)/i))) {    location.replace("http://m.xuebuyuan.com") }else{ document.write("請使用手機訪問."); }
