The example in this article describes how to use JavaScript to generate bubbles where the mouse slides over. Share it with everyone for your reference. The specific implementation method is as follows: 

<HTML>
<HEAD>
<title>鼠标周围在网页上生成气泡</title>
</HEAD>
<BODY bgColor=#000000 scroll=no onload=zyva()>
<div id=aqua style="position:absolute;left=0;top=0;"></div>
<IMG id=B src="b1.gif" style="display:none">
<SCRIPT>
object = new Array()
var xm,ym
function CObj(N,obj){
aqua.insertAdjacentHTML("AfterBegin","<img style='position:absolute;left:-1000;' src='"+obj.src+"'>")
this.img = aqua.firstChild.style
mr = Math.random()
this.v = 6*mr+4
this.s = .5*mr
this.p = .1+mr
this.w = 0
this.k = 0
this.x = xm
this.y = N
this.ChteuMeulEu = function ChteuMeulEu(){
with(this){
with(img){
left = (x+=0.5*v*Math.sin(k+=s))-w*0.5
top = y-=v
width = Math.min(w+=p,100)
}
if(y<-w){
w = 8
y = ym
x = xm
}
}
}
}
function gradient(R,G,B,m){
for(i=0;i<25;i++){
c = 255 - 10 * i
C = "\"RGB("+Math.round(c*R/255)+","+Math.round(c*G/255)+","+Math.round(c*B/255)+")\""
code = "<span style='position:absolute;font-size:1pt;left=0;width=120%;height="+(m)+".2%;top="+(i*m)
+"%;background="+C+";z-Index:-1000'></span>"
document.body.insertAdjacentHTML("beforeEnd",code)
}
}
function zyva(){
xm = document.body.offsetWidth * 0.5
ym = document.body.offsetHeight
document.onmousemove = function (){
xm = window.event.clientX
ym = window.event.clientY
}
for(i=0;i<60;i++)object[i] = new CObj(i,B)
setInterval("for(i in object)object[i].ChteuMeulEu()",16)
gradient(41,93,214,2)
}
</SCRIPT>
</BODY>
</HTML>

I hope this article will be helpful to everyone’s JavaScript programming design.
