setInterval 在此代码中无法正常工作
<script language="javascript">
x = y = 0;
function mvtb(p, g){
i = 0;
tmp = setInterval(function (){
if(i < 100 && i >= 0){
document.getElementById("plan").scrollTop = 200*(y+((y-g)*(i/100)));
document.getElementById("plan").scrollLeft = 660*(x+((x-p)*(i/100)));
i++;
}
else if(i == 100){
clearInterval(tmp);
}
}, 10);
x = p; y = g;
}
</script>

试试这个.仅在动画结束后更新g和p,并在计算新的scrollTop/scrollLeft时交换减法.你还需要确保循环运行100次,而不是99. JSFiddle
x = y = 0;
function mvtb(p, g) {
var i = 1;
var tmp = setInterval(function() {
if (i <= 100 ) {
document.getElementById("plan").scrollTop = 200 * (y + ((g - y) * (i / 100)));
document.getElementById("plan").scrollLeft = 660 * (x + ((p - x) * (i / 100)));
i++;
}
else {
clearInterval(tmp);
x = p;
y = g;
}
}, 10);
}
