如何为此使用addEventListener？

Question

I am trying to add an event listener to child divs within a container div. I am having an issue with figuring out how to do this properly. The code I have so far is here: pastebin . The listener (click) is on line 35

Answer 1

You're calling the context function instead of passing it as a listener. I mean, this:

divs[i].addEventLisenter('click', context(divs[i].id), true);

should be:

divs[i].addEventLisenter('click', context, true);

And this:

function context(id) {
    console.log(id+' clicked');
}

should be:

function context(evt) {
    console.log(this.id + ' clicked');
}

Answer 2

JavaScript是经过解释的，因此您应该将docINIT的定义移至其使用之上。
