Question

onStartParams: Array
传递给onStart回调函数的参数数组，例如

new TimelineMax({onStart: myFunction, onStartParams: ["param1", "param2"]}); 

如果想传递时间轴对象本身，可使用{self}，如 onStartParams:["{self}", "param2"]
onStartParams适用于TimelineMaxTimelineLite

onStartParams的参数

onStartParams 示例

.box {
    width:50px;
    height:50px;
    border-radius:6px;
    margin-top:4px;
    display:inline-block
  }
.green{
    background-color:#6fb936;
  }

var tm= new TimelineMax({delay: 1, onStart: onStart, onStartParams: ["{self}", "param2"]})
tm.to('.box', 2, {x: 500});
panel = document.getElementById("panel");
function onStart(param1, param2){
  panel.innerHTML = param1 + param2;
  //param1是此时间轴对象，param2是传递的字符串
}

onStartParams返回值
