javascript-将事件和参数传递给使用addEventListener调用的函数

Question

window.addEventListener("keyup", eventkeyup(event, something), false);

    function eventkeyup(event, something) {

    //could not be able to get the event object here.

}

如何使用此功能访问事件？

Answer 1

传递函数本身，而不返回其值undefined。

window.addEventListener("keyup", eventkeyup(something), false);

function eventkeyup(something) {
    return function(event){
       // you have event and something here
    }
}
