JAVASCRIPT中怎么判斷訪客終端是電腦還是手機(jī)

JAVASCRIPT中怎么判斷訪客終端是電腦還是手機(jī)，針對(duì)這個(gè)問(wèn)題，這篇文章詳細(xì)介紹了相對(duì)應(yīng)的分析和解答，希望可以幫助更多想解決這個(gè)問(wèn)題的小伙伴找到更簡(jiǎn)單易行的方法。

我們使用PHP的$_SERVER['HTTP_USER_AGENT']來(lái)獲取手機(jī)用戶瀏覽器的用戶代理，然后匹配已有的各種手機(jī)瀏覽器代理庫(kù)，如果含有匹配的關(guān)鍵字，則判斷為手機(jī)（移動(dòng)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(shù)is_mobile()來(lái)判斷用戶終端類型，將收集到的當(dāng)今各種手機(jī)的HTTP_USER_AGENT歸結(jié)到數(shù)組$mobile_agents中，并進(jìn)行匹配。使用時(shí)只需調(diào)用函數(shù)is_mobile()。如以下代碼表示，當(dāng)匹配用戶為手機(jī)訪問(wèn)時(shí)，頁(yè)面跳轉(zhuǎn)到網(wǎng)站手機(jī)版m.xuebuyuan.com。

if (is_mobile()) { header('Location:http://m.xuebuyuan.com'); } else { echo '請(qǐng)使用手機(jī)訪問(wèn).'; }

Javascript版

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

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(qǐng)使用手機(jī)訪問(wèn)."); }
