我想正确地旋转图标，点击相应的图标
提问于 2016-08-23 22:18:45
在这个html代码中，我尝试旋转一个图标180度，点击相应的图标，然后在单击其他图标或外部时返回。这里的问题是，当单击第二个图标时，第一个图标不会返回，而第二个图标是不返回的，要么单击第一个图标，要么单击外部。怎么修呢？
function rotate(e){
document.getElementById("me").className="spinner in fa fa-caret-down";
e.stopPropagation();
}
function resetRotation(){
document.getElementById("me").className="spinner out fa fa-caret-down";
}
document.addEventListener('click', resetRotation);
function rotatea(e){
document.getElementById("you").className="spinner in fa fa-caret-down";
e.stopPropagation();
}.spinner {
transition: all 0.5s linear;
}
.spinner.in{
transform: rotate(180deg);
}
.spinner.out{
transform: rotate(0deg);
