在大學(xué)里的時(shí)候，沒有什么危機(jī)感，無視自己知識(shí)的貧乏。每天僅憑著自己對(duì)知識(shí)的興趣充實(shí)著自己。偶爾在新浪博客里寫寫文章，懺悔自己虛度的年華。那時(shí)候?qū)W會(huì)了使用網(wǎng)頁特效代碼，現(xiàn)在學(xué)了java，就試著去理解一下它們。
<script language="JavaScript">
 step=0
 function flash_title()
 { step++
  if (step==5)
  {step=1}
   if (step==1) {
   document.title=' ◆◇◇認(rèn)識(shí)你真好◇◇◆ '}
   if (step==2)
    {document.title=' ◇◆◇認(rèn)識(shí)你真好◇◆◇ '}
 if (step==3)
  {document.title=' ◇◇◆認(rèn)識(shí)你真好◆◇◇ '}
  if (step==4) {document.title=' ◇◆◇認(rèn)識(shí)你真好◇◆◇ '}
  setTimeout("flash_title()",400); }
  flash_title() ；
</script>
這段代碼中只涉及一點(diǎn)非java的內(nèi)容，就是document.title='           '；這是定義本頁的標(biāo)題欄的，在單引號(hào)里寫的東西和在<title></title>之間寫東西是一樣的。
所以這段代碼就是：
----定義一個(gè)簡單的java 函數(shù)
----設(shè)定函數(shù)每一步的執(zhí)行間隔
----實(shí)例化函數(shù)（相當(dāng)于在main里調(diào)用）。

 

 <script language="JavaScript">

this.msg = MESSAGE

scroll.out = " "
scroll.pos--
if (scroll.pos < -(scroll.msg.length)) {
scroll.reset()
}
setTimeout ('scroller()',scroll.delay)
}
function snapIn(jumpSpaces,position) {
var msg = scroll.msg
var out = ""
for (var i=0; i<position; i++)
{out += msg.charAt(i)}
for (i=1;i<jumpSpaces;i++)
{out += " "}
out += msg.charAt(position)
window.status = out
if (jumpSpaces <= 1) {
position++
if (msg.charAt(position) == ' ')
{position++ }
jumpSpaces = 100-position
} else if (jumpSpaces > 3)
{jumpSpaces *= .75}
else
{jumpSpaces--}
if (position != msg.length) {
var cmd = "snapIn(" + jumpSpaces + "," + position + ")";
scrollID = window.setTimeout(cmd,scroll.delay);
} else {
window.status=""
jumpSpaces=0
position=0
cmd = "snapIn(" + jumpSpaces + "," + position + ")";
scrollID = window.setTimeout(cmd,scroll.delay);
return false
}
return true
}
snapIn(100,0);
// -->
</script>

這里的  window.status=""  是定義狀態(tài)欄的，這個(gè)例子和上一個(gè)差不多，只是看起來復(fù)雜了些。
