Dugme za start JavaScripta

^{16.08.2010. u 20:09 - pre 167 meseci}

kao sto sam naziv govori, potrebno mi je dugme za start jedne skripte.
Skripta izgleda ovako:

Code:
<script type="text/javascript">
/*<![CDATA[*/var el="div_for_bg";var bgimg=new
Array(
"http://img819.imageshack.us/img819/",
"http://img651.imageshack.us/img651/",
"http://img801.imageshack.us/img801/",
"http://img64.imageshack.us/img64/",
"http://img820.imageshack.us/img820/",
"http://img85.imageshack.us/img85/551/",
"http://img5.imageshack.us/img5/2133/",
"http://img831.imageshack.us/img831/",
"http://img809.imageshack.us/img809/",
"http://img836.imageshack.us/img836/",
"http://img708.imageshack.us/img708/",
"http://img810.imageshack.us/img810/",
"http://img25.imageshack.us/img25",
"http://img832.imageshack.us/img832/",
"http://img821.imageshack.us/img821/",
"http://img576.imageshack.us/img576/",
"http://img534.imageshack.us/img534/",
"http://img186.imageshack.us/img186/",
"http://img689.imageshack.us/img689",
"http://img651.imageshack.us/img651/",
"http://img42.imageshack.us/img4");
var random=Math.round((bgimg.length-1)*Math.random());var cssStr="#"+el+" { background: url("+bgimg[random]+") no-repeat top left } ";var style=document.createElement("style");style.setAttribute("type","text/css");if(style.styleSheet){style.styleSheet.cssText=cssStr;}else{var cssText=document.createTextNode(cssStr);style.appendChild(cssText);}document.getElementsByTagName("head")[0].appendChild(style);/*]]>*/
</script>

to je skripta za postavljanje pozaadine sajta po "random" funkciji.
ali, skripta se pokrece zajedno sa stranicom sajta - i sve odlicno radi.
ali - ja zelim da napravim dugme, koje ce pokretati ovu skriptu izova svaki put kada se na njega klikne. Mozete li mi pomoci kako da napravim ovo dugme ?
Hvala !

Pa vjerovatno tako sto ovaj kod postavis u funkciju (npr test() ) i zatim napravis dugme u HTML sa onClick dogadjajem:

<input type="button" onClick="test()">

var random=Math.round((bgimg.length-1)*Math.random());
var cssStr="#"+el+" { background: url("+bgimg[random]+") no-repeat top left } ";
var style=document.createElement("style");style.setAttribute("type","text/css");

if(style.styleSheet){
    style.styleSheet.cssText=cssStr;
}
else{
    var cssText=document.createTextNode(cssStr);
    style.appendChild(cssText);
}

document.getElementsByTagName("head")[0].appendChild(style);/*]]>*/
        }
</script>

a dugme ovako:

Code:

<form method="post">

<input type="image" value="" size="" src="img/other_background_btn.png"
onClick="test()" /></form>

Moras pozvati tu metodu na pocetku.

Code:

window.onload=test;

ili u body

<body onload="test();">

ili je samo pzoves

test();

To sada napises unutra tag-ova JavaScript-a.

Napravio si funkciju, onda je pozoves na ucitavanju stranice (automatski) ili rucno kliktajem na dugme.
