分手机端和PC端其实方法很多,我们在响应式设计、响应式网站建设中经常碰到此类需求。下面说说我们在项目中遇到的需求:
手机端和PC端分别加载不同的js客服代码(注意:是要在PC和手机端分别加载不同的js文件)
第一种方法(简单型):
<script type="text/javascript">
// 根据屏幕尺寸
if (screen && screen.width > 480) {
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
}
// userAgent判断
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>
第二种方法(已测试通过,项目真实在用):
<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("您的浏览设备为:");
if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
// alert("手机浏览!");
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
} else {
// alert("PC浏览!");
document.write('<script type="text/javascript" charset="utf-8" src="123.js"><\/script>');
}
}
browserRedirect();
</script>
这样子我们直接在PC端和手机端分别输出不同的js。所以,我们在手机端和PC端分别加载不同的js的需求完美解决了。
