网页的DOCTYPE HTML public 会导致页面的部分事件不触发

最近忙着做JS，在JS里头有用到鼠标的一些事件时，通常我都是把鼠标事件包含在一个JS文件中调用
<script type="text/javascript" src="js/sb_cd.js"></script>

在鼠标事件中若包含如下鼠标的特效，就会导致事件触发：js/sb_cd.js
// JavaScript Document 

var sb_cd_a_Colour='fff000';
var sb_cd_b_Colour='00ff00';
var sb_cd_c_Colour='ff00ff';
var sb_cd_Size=120;

var sb_cd_YDummy=new Array(),sb_cd_XDummy=new Array(),sb_cd_xpos=0,sb_cd_ypos=0,sb_cd_ThisStep=0;sb_cd_step=0.6;
if (document.layers){
window.captureEvents(Event.MOUSEMOVE);
function sb_cd_nsMouse(evnt){
sb_cd_xpos = window.pageYOffset+evnt.pageX+6;
sb_cd_ypos = window.pageYOffset+evnt.pageY+16;
}
window.onMouseMove = sb_cd_nsMouse;
}
else if (document.all)
{
function sb_cd_ieMouse(){
sb_cd_xpos = document.body.scrollLeft+event.x+6;
sb_cd_ypos = document.body.scrollTop+event.y+16;
}
document.onmousemove = sb_cd_ieMouse;
}

function sb_cd_swirl(){
for (i = 0; i < 3; i++)
 {
 sb_cd_YDummy[i]=sb_cd_ypos+sb_cd_Size*Math.sin((1*Math.sin((sb_cd_ThisStep)/10))+i*2)*Math.sin((sb_cd_ThisStep)/4);
 sb_cd_XDummy[i]=sb_cd_xpos+sb_cd_Size*Math.cos((1*Math.sin((sb_cd_ThisStep)/10))+i*2)*Math.sin((sb_cd_ThisStep)/4);
 }
sb_cd_This
