Element.classList Kann nicht Eigentum 'Toggle'

Question

Ich erhalte diesen Fehler lesen:

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

Kann jemand helfen?

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

Es ist gut!

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); 
}
