Question

网页中一条JS可以多次调用么？帮写下第二个源代码，让两个都能被JS同时被调用。谢谢了

<script>
var $ = function(id){return document.getElementById(id)};
var wrap = $("wrap");
var a = $("a");
var b = $("b");
var show = $("show");
var d;
b.innerHTML = a.innerHTML;
function scrolls(){
d = "n";
if(b.offsetWidth - wrap.scrollLeft <=0){
wrap.scrollLeft = wrap.scrollLeft - b.offsetWidth;
}
else{
wrap.scrollLeft++;
}
}

t = setInterval("scrolls()",10)

function backScrolls(){
if(wrap.scrollLeft <=0){
wrap.scrollLeft = wrap.scrollLeft + b.offsetWidth;
}
else{
wrap.scrollLeft--;
}
}
function left(){
d = "n";
clearT();
t = setInterval("scrolls()",10);
}
function right(){
d = "m";
clearT();
t = setInterval("backScrolls()",10);
}
function clearT(){
clearInterval(t);
}
function runs(){
if(d == "n"){
left();
}
else{
right();
}
}
wrap.onmouseover = function (){
clearT();
}
wrap.onmouseout = function(){
runs();
}
</script>

Answer 1

<select id="s1"
id请不要设为一样，否则只有第一个有效...
