腳本只能在IE

Question

工作，我有以下的JavaScript顯示行駛路線：

<script type="text/javascript" language="javascript"> 


//Change script's width (in pixels) 
var marqueewidth=800 
//Change script's height (in pixels, pertains only to NS) 
var marqueeheight=20 
//Change script's scroll speed (larger is faster) 
var speed=3 
//Change script's contents 
var marqueecontents='You text here' 

if (document.all) 
document.write('<marquee scrollAmount='+speed+' style="width:'+marqueewidth+'">'+marqueecontents+'</marquee>') 

function regenerate(){ 
window.location.reload() 
} 
function regenerate2(){ 
if (document.layers){ 
setTimeout("window.onresize=regenerate",450) 
intializemarquee() 
} 
} 

function intializemarquee(){ 
document.cmarquee01.document.cmarquee02.document.write('<nobr>'+marqueecontents+'</nobr>') 
document.cmarquee01.document.cmarquee02.document.close() 
thelength=document.cmarquee01.document.cmarquee02.document.width 
scrollit() 
} 

function scrollit(){ 
if (document.cmarquee01.document.cmarquee02.left>=thelength*(-1)){ 
document.cmarquee01.document.cmarquee02.left-=speed 
setTimeout("scrollit()",100) 
} 
else{ 
document.cmarquee01.document.cmarquee02.left=marqueewidth 
scrollit() 
} 
} 

window.onload=regenerate2 
</script> 

我應該在劇本修改，使其在FF和Chrome瀏覽器？ 謝謝

Answer 1

您的代碼包含if (document.all)行，所以Marquee只會被寫入到IE中的文檔中。

我刪除了這一行，它似乎在Firefox中工作。我沒有在這臺機器上測試Chrome。

Answer 2

1. 缺少分號
2. document.write()
3. document.all
4. <marquee>
5. 全局
6. 字符串作爲setTimeout功能
7. 無壓痕

懷舊......它就像是1998年。
