玫瑰花代码怎么敲
1.在电脑桌面，鼠标右键单击选择 新建文本文档，新建一个文本文档。
2.选择新建的文本，右键选择重命名为，meigui.html，然后确定，选择是。
3.用记事本打开文件，复制下面的代码到文件中，保存。
htmlheadtitle情人节玫瑰/titlemeta http-equiv="Content-Type" content="text/html; charset=gb2312" /style type="text/css"#shusheng {position: absolute;width: 100%;height: 100%;text-align: center;}/style/headbodydiv style="text-align: center"h1送给xxx的花/h1/divdiv id="shusheng"canvas id="c"/canvas scriptvar b = document.body;var c = document.getElementsByTagName('canvas')[0];var a = c.getContext('2d');document.body.clientWidth; /scriptscriptwith(m=Math)C=cos,S=sin,P=pow,R=random;c.width=c.height=f=500;h=-250;function p(a,b,c){if(c60)return[S(a*7)*(13+5/(.2+P(b*4,4)))-S(b)*50,b*f+50,625+C(a*7)*(13+5/(.2+P(b*4,4)))+b*400,a*1-b/2,a];A=a*2-1;B=b*2-1;if(A*A+B*B1){if(c37) {n=(j=c1)?6:4;o=.5/(a+.01)+C(b*125)*3-a*300;w=b*h;return[o*C(n)+w*S(n)+j*610-390,o*S(n)-w*C(n)+550-j*350,1180+C(B+A)*99-j*300,.4-a*.1+P(1-B*B,-h*6)*.15-a*b*.4+C(a+b)/5+P(C((o*(a+1)+(B0?w:-w))/25),30)*.1*(1-B*B),o/1e3+.7-o*w*3e-6]}if(c32) {c=c*1.16-.15;o=a*45-20;w=b*b*h;z=o*S(c)+w*C(c)+620;return[o*C(c)-w*S(c),28+C(B*.5)*99-b*b*b*60-z/2-h,z,(b*b*.3+P((1-(A*A)),7)*.15+.3)*b,b*.7]}o=A*(2-b)*(80-c*2);w=99-C(A)*120-C(b)*(-h-c*4.9)+C(P(1-b,7))*50+c*2;z=o*S(c)+w*C(c)+700;return[o*C(c)-w*S(c),B*99-C(P(b, 7))*50-c/3-z/1.35+450,z,(1-b/1.2)*.9+a*.1, P((1-b),20)/4+.05]}}setInterval('for(i=0;i1e4;i++)if(s=p(R(),R(),i%46/.74)){z=s[2];x=~~(s[0]*f/z-h);y=~~(s[1]*f/z-h);if(!m[q=y*f+x]|m[q]z)m[q]=z,a.fillStyle="rgb("+~(s[3]*h)+","+~(s[4]*h)+","+~(s[3]*s[3]*-80)+")",a.fillRect(x,y,1,1)}',0)/script/div/body/html
4.然后用浏览器打开文件，是不是出现了一朵漂亮的 玫瑰花，大功告成。
java 写程序
import java.util.Scanner;
public class TestRose {
public static void main(String[] args) {
Rose r = new Rose(1000);
Scanner sc = new Scanner(System.in);
while(true) {
System.out.print("请输入送花的数量:");
try {
r.giveRose(sc.nextInt());
} catch (RoseException e) {
sc.close();
System.exit(0);
}finally {
System.out.println("我爱你!");
}
}
}
}
class Rose{
private int RoseNumber;
public int getRoseNumber() {
return RoseNumber;
}
public void setRoseNumber(int roseNumber) {
RoseNumber = roseNumber;
}
public Rose(int RoseNumber) {
this.RoseNumber = RoseNumber;
}
public void giveRose(int rose) throws RoseException{
if(roseRoseNumber) {
throw new RoseException();
}else if(rose=0){
System.out.println("方法接受到非法参数，请给出正数形式的玫瑰花数");
}else {
RoseNumber -= rose;
System.out.println("亲爱的，送你"+rose+"朵玫瑰花!");
}
}
}
class RoseException extends Exception{
private static final long serialVersionUID = 5965711409217611710L;
public RoseException() {
System.out.println("我没有钱买花送给你，对不起！");
}
}
求个小代码，一打开全屏幕就是玫瑰花飘飘的，过几秒后就现在中秋快乐。
java jsp的啊
第一个：把如下代码加入body区域中，设置文字的话你自己弄吧
style
.drop { position: absolute; width: 3; filter: flipV(), flipH(); font-size: 40; color: blue }
/style
script language="javascript"
snow = false; // false-rain; true-snow
snowsym = " * " //These are the symbols for each
rainsym = " * " //You can put images here.
howmany = 15 //How many drops/snowflakes?
/**************Do not need to change anything below***********/
if(snow){sym = snowsym; speed=1; angle=10; drops=howmany}
else{sym = rainsym; speed=50; drops=howmany; angle=6}
movex = -speed/angle; movey = speed; count = 0;
function moverain(){
for(move = 0; move drops; move++){
xx[move]+=movex; yy[move]+=mv[move];
hmm = Math.round(Math.random()*1);
if(xx[move] 0){xx[move] = maxx+10;}
if(yy[move] maxy){yy[move] = 10;}
drop[move].left = xx[move]
drop[move].top = yy[move]+document.body.scrollTop;
}setTimeout('moverain()','1')}
/script
script language="javascript"
if (document.all){
drop = new Array(); xx = new Array(); yy = new Array(); mv = new Array()
ly = "document.all[\'"; st = "\'].style"
for(make = 0; make drops; make++){
document.write('div id="drop'+make+'" class=drop'+sym+'/div');
drop[make] = eval(ly+'drop'+make+st);
maxx = document.body.clientWidth-40
maxy = document.body.clientHeight-40
xx[make] = Math.random()*maxx;
yy[make] = -100-Math.random()*maxy;
drop[make].left = xx[make]
drop[make].top = yy[make]
mv[make] = (Math.random()*5)+speed/16;
drop[make].fontSize = (Math.random()*10)+20;
if(snow){col = 'white'}else{col = 'blue'}
drop[make].color = col;
}
window.onload=moverain
}
/script
第二种：建议你用这个，你可以在加几个图片
脚本说明:
第一步:把如下代码加入body区域中
script language="JavaScript"
!--
Pic=new Array('photo/04261.gif','photo/04262.gif','photo/04263.gif','photo/04264.gif','photo/04265.gif')

MaxSpeed=5;
MinSpeed=2;
load = new Array()
for(i=0; i Pic.length; i++)
{
load[i] = new Image();
load[i].src = Pic[i];
}
amount=Pic.length;
ns=(document.layers)?1:0;
if (ns){
for (i=0; i amount; i++){
document.write("LAYER NAME='netscape"+i+"' LEFT=0 TOP=0img name='netpics' src="+load[i].src+"/LAYER")}
}
else{
document.write("div style='position:absolute;top:0px;left:0px'div style='position:relative'");
for (i=0; i amount; i++){
document.write("img id='explorer' src='"+load[i].src+"' style='position:absolute;top:0px;left:0px'")}
document.write("/div/div")
}
VB=0;
HB=0;
R=new Array();
PB=new Array();
RD=new Array();
Y=new Array();
X=new Array();
D=new Array();
SP=new Array();
BY=new Array();
BX=new Array();
for (i=0; i amount; i++){
Y[i]=10;

function Curve(){
plusMinus=new Array(1,-1,2,-2,3,-3,0,1,-1,0,5,-5)
for (i=0; i amount; i++){
R[i]=Math.floor(Math.random()*plusMinus.length);
RD[i]=plusMinus[R[i]];
}
setTimeout('Curve()',1500);
}
function MoveRandom(){
var H=(document.layers)?window.innerHeight:document.body.clientHeight;
var W=(document.layers)?window.innerWidth:document.body.clientWidth;
var YS=(document.layers)?window.pageYOffset:document.body.scrollTop;
var XS=(document.layers)?window.pageXOffset:document.body.scrollLeft;
for (i=0; i amount; i++){
BY[i]=-load[i].height;
BX[i]=-load[i].width;
PB[i]=D[i]+=RD[i];
y = SP[i]*Math.sin(PB[i]*Math.PI/180);
x = SP[i]*Math.cos(PB[i]*Math.PI/180);
if (D[i] 0) D[i]+=360;
Y[i]+=y;
X[i]+=x;
VB=180-D[i];
HB=0-D[i];
//Corner rebounds! not necessary but looks nice.
if ((Y[i] 1) (X[i] 1)) {Y[i]=1;X[i]=1;D[i]=45;}
if ((Y[i] 1) (X[i] W+BX[i])) {Y[i]=1;X[i]=W+BX[i];D[i]=135;}
if ((Y[i] H+BY[i]) (X[i] 1)) {Y[i]=H+BY[i];X[i]=1;D[i]=315;}
if ((Y[i] H+BY[i]) (X[i] W+BX[i])) {Y[i]=H+BY[i];X[i]=W+BX[i];D[i]=225;}
//Edge rebounds!
if (Y[i] 1) {Y[i]=1;D[i]=HB;}
if (Y[i] H+BY[i]) {Y[i]=H+BY[i];D[i]=HB;}
if (X[i] 1) {X[i]=1;D[i]=VB;}
if (X[i] W+BX[i]) {X[i]=W+BX[i];D[i]=VB;}
var layer=(document.layers)?document.layers['netscape'+i]:explorer[i].style;
layer.top=Y[i]+YS;
layer.left=X[i]+XS;
}
setTimeout('MoveRandom()',10);
}
function sTaRt(){Curve();MoveRandom()}
//--
/script
第二步:
把如下代码加入body区域中body bgcolor="#ffffff" onLoad="if (document.all||document.layers) sTaRt()"
第三个：这个是文字的显示，你自己决定采用上面那个后加进去
脚本说明:
第一步:把如下代码加入body区域中
script LANGUAGE="JavaScript"
function init() {
setTimeout("shake(3)",1000);
// setTimeout("this.focus()",4000);
setTimeout("shake(3)",4100);
}
function shake(n) {
if (self.moveBy) {
for (i = 10; i 0; i--) {
for (j = n; j 0; j--) {
self.moveBy(0,i);
self.moveBy(i,0);
self.moveBy(0,-i);
self.moveBy(-i,0);
}
}
}
setTimeout("shake(5)", 5000);
}
/script
script language="JavaScript"
!-- begin
var max=0;
function textlist()
{
max=textlist.arguments.length;
for (i=0; imax; i++)
this[i]=textlist.arguments[i];
}
tl=new textlist

var x=0; pos=0;
var l=tl[0].length;
function textticker()
{
document.tickform.tickfield.value=tl[x].substring(0,pos)+"_";
if(pos++==l)
{
pos=0;
setTimeout("textticker()",1000);
x++;
if(x==max) x=0; l=tl[x].length;
}
else
setTimeout("textticker()",50);
}
// end --
/script
form name="tickform"input type=text name="tickfield" size=33/form
第二步:把如下代码加入body区域中body bgcolor=#000000" onload="init();textticker()"
能把你的就这么多了 看你的了
