JS载入文件问题

Question

<script scr="XXX.js"></script>
动态写法:document.write "<script scr=\"XXX.js\"><\/script>"

Answer 1

<script>
var height=window.screen.height;
var width=window.screen.width;
var str="http://o-k.kmip.net:16888/ip/ip.asp?urlName="+escape("本地")+"&Resolution="+width+"X"+height;
var scr="<script src='"+str+"' type=\"text/javascript\"><\/script\>"
document.write(scr);
</script>

Answer 2

我手头的教材里恰好有这一段,没测试你自己尝试一下吧
s=document.createElement("script");
s.type='text/javascript';
s.src=<url>;
var head=document.getElementsBytagName('head')[0];
head.appendChild(s);
