[RESOLVED] need help for "looping"

[merhaba]

Hi, I want to use a "for loop" to shorten the coding for the "if....." part only, but I am not sure how to...
//I am tring this but..
for (var m=1;m<4;m++)
{
if(horse[m].style.posLeft>800)
{
alert(m+"..horse won the race")
}

}


could anyone help me?



Thanks

 <script> 
var sstop=setInterval("run()",50) 
function run() 
{ 
document.getElementById("horse1"); 
document.getElementById("horse2"); 
document.getElementById("horse3"); 
document.getElementById("horse4"); 
horse1.style.posLeft=horse1.style.posLeft+(Math.random()*10)+1; 
horse2.style.posLeft=horse2.style.posLeft+(Math.random()*10)+1; 
horse3.style.posLeft=horse3.style.posLeft+(Math.random()*10)+1; 
horse4.style.posLeft=horse4.style.posLeft+(Math.random()*10)+1; 
if(horse1.style.posLeft>800) 
{ 
alert("horse1 won the race") 
horse1.style.posLeft=10; 
horse1.style.posLeft=horse1.style.posLeft+(Math.random()*0)+1; 
//.................... 
//............... 
} 
} 
</script> 
<img src="horse.gif" id=horse1 style="position:absolute;top:200;left:10;"> 
<img src="horse.gif" id=horse2 style="position:absolute;top:230;left:10;"> 
<img src="horse.gif" id=horse3 style="position:absolute;top:260;left:10;"> 
<img src="horse.gif" id=horse4 style="position:absolute;top:290;left:10;">

Why not use while?

var i = 1;
while (i < 5) {
    var horse = document.getElementById('horse' + i);
    horse.style.posLeft = horse.style.posLeft + (Math.random()*10) + 1;
    if(horse.style.posLeft >= 800) {
        alert('Horse ' + i + ' won the race!');
        var j = 1;
        while (j < 5) { document.getElementById('horse' + j).style.posLeft = 10; j++; }
    }
    i++;
}

Remember to test with something else than IE, too. There are some differences between browsers.

Oh, just noticed:

horse.style.posLeft = horse.style.posLeft +

could be:

horse.style.posLeft +=

No need to repeat that twice
