数据库用UTF-8，现有系统用gb2312,

用<script>echo_script(url);</script>

复制代码 代码如下:

<script>

function echo_script(url){

var USERAGENT = navigator.userAgent.toLowerCase();

var bname = '';

var b = ['ie','msie','firefox','chrome','opera','safari','maxthon','mozilla','webkit'];

for(i in b){

if(USERAGENT.indexOf(b[i]) > -1){

bname = b[i];

break;

}

}

if(!bname)bname='other';

var ie8 = USERAGENT.indexOf('msie 8') > -1 ? 'ie8' : false;

var ie7 = USERAGENT.indexOf('msie 7') > -1 ? 'ie7' : false;

if(bname == 'firefox' || ie8 )

{

var enc = "no";

}

if(ie8){

bname = 'ie8';

}else if(ie7){

bname = 'ie7';

}

var tmp_ie8 = ie8 ? 'ie8' : 'no_ie8';

document.write("<script src='"+url+"&encode="+enc+"&browser="+tmp_ie8+"&browserv="+bname+"'></script>");

}

</script>

哎，这种方法，导致在不同的浏览器下乱码不断，害苦我了。

有更简单的办法

<script type="text/javascript" charset="utf-8" src="xx.com/xx.php"></script>

乱码从此不再出现！
