您可以在匿名函数内部调用该函数：
b.addEventListener("click", function() {colorIt(p)} );
function start() {
var p = document.getElementById("myP");
var b = document.getElementById("myB");
b.addEventListener("click", function() {colorIt(p)} );
}
function colorIt(ele){
ele.setAttribute("style", "color : red" );
}
window.addEventListener("load", start , false);
<button id="myB"> click me </button>
<p id ="myP"> test </p>
