手機端和PC端分別加載不一樣的js客服代碼(注意:是要在PC和手機端分別加載不一樣的js文件)java
第一種方法(簡單型):android
<script type="text/javascript">
// 根據屏幕尺寸
if (screen && screen.width > 480) {
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
}
// userAgent判斷
if( /Android|webOS|iPhone|iPod|iPad|BlackBerry/i.test(navigator.userAgent)){
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
}
</script>
第二種方法(已測試經過,項目真實在用):web
<script type="text/javascript">
function browserRedirect() {
var sUserAgent = navigator.userAgent.toLowerCase();
var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
var bIsMidp = sUserAgent.match(/midp/i) == "midp";
var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
var bIsAndroid = sUserAgent.match(/android/i) == "android";
var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
// document.writeln("您的瀏覽設備爲:");
if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
// alert("手機瀏覽!");
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
} else {
// alert("PC瀏覽!");
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
}
}
browserRedirect();
</script>
這樣子咱們直接在PC端和手機端分別輸出不一樣的js。因此,咱們在手機端和PC端分別加載不一樣的js的需求完美解決了。 windows
