javascript - for 循环中的引用数组生成悬停事件

Question

如何引用与 for 循环中使用的数组具有相同索引的数组项？

animations[i] 当前返回未定义:

var icons = ["#know","#run","#think","#done","#measure","#plan","#resolve"]
var animations = [knowTl,runTl,thinkTl,doneTl,measureTL,planTl,resolveTl]

for(var i=0;i<icons.length;i++) {
$(icons[i]).hover(
  function() {
  animations[i].restart()
  },
  function() {}
 );
}

Answer 1

这样做

for(var i=0;i<icons.length;i++) {
(function(i){
  $(icons[i]).hover(
    function() {
      animations[i].restart()
    },
    function() {}
   );
})(i)
}
