Element.classList 无法阅读属性 'toggle'

Question

我收到此错误：

Uncaught TypeError: Cannot read property 'toggle' of undefined at HTMLTableCellElement.toto

有人可以帮忙吗？

var comments = document.getElementsByClassName('organisation');
var numComments = comments.length;

function toto(e){
    /*this.style.cssText='background-color:white';*/
    comments.classList.toggle('.maClasse');
}

for (var i = 0; i < numComments; i += 1) {
    comments[i].addEventListener('click', toto, false);
}

Answer 1

很好！

var comments = document.getElementsByClassName('organisation');
var numComments = comments.length;

//function toto(e){
    //this.style.cssText='background-color:white';
    //comments.classList.toggle('.maClasse')
    function myFunction() {
        this.classList.toggle("maClasse");
    };
//}

for (var i = 0; i < numComments; i += 1) {
    comments[i].addEventListener('click', myFunction, false);
}
