javascript - 如何阻止此事件监听器自动触发

Question

我有这个自执行函数，它将事件监听器添加到一系列链接中。但事件监听器会在页面加载时自动触发，而不是 onmouseover/out。我语法错误吗？我如何阻止它们自动射击？

;(function(){
    var menuLink = $('.navItem');
    var menuItem = $('.menuLinks');
    for (a = 0; a <= 5; ++a) {
        menuLink[a].addEventListener('onmouseover', linkChanger(), true);
        menuLink[a].addEventListener('onmouseout', linkChanger(), true);
    }   

    function linkChanger(event){
        if (menuItem[a].style.color == "white") {
            console.log("This is white")
            menuItem[a].style.color = "black";
        }
        else {
            console.log("This is black");
            menuItem[a].style.color = "white";
        }
    }
})()

Answer 1

menuLink[a].addEventListener('onmouseover', linkChanger, true);
menuLink[a].addEventListener('onmouseout', linkChanger, true);
