js根据不同浏览器(分辨率)调用不同css

根据不同浏览器：

<script type="text/javascript">

var version = navigator.userAgent;

if (version.indexOf("MSIE") > 1) {

document.write("<link href='ie.css' rel='stylesheet' type='text\/css'\/>");

} else if (version.indexOf("Chrome") > 1) {

document.write("<link href='chrome.css' rel='stylesheet' type='text\/css'\/>");

} else if (version.indexOf("Firefox") > 1) {

document.write("<link href='ff.css' rel='stylesheet' type='text\/css'\/>");

}

</script>

根据不同分辨率：

<script type="text/javascript">

if (screen.width == 1024){

document.write("<link href='css/css1.css' rel='stylesheet' type='text\/css'\/>");

}else {

document.write("<link href='css/css2.css' rel='stylesheet' type='text\/css'\/>");}

</script>
