how to use "attachEvent"?;

[SkyZhao]

i use attachEvent to bind a event ;
code:
img.attachEvent("onclick",alert("aa"));
div.appendChild(img);
div.innerHTML+="some text";

the event can not work; why can't i use it?

if i use nether code , it can work;

code:
img.attachEvent("onclick",alert("aa"));
div.appendChild(img);
spanWord = document.createElement("span");
spanWord.innerHTML="some text";
div.appendChild(spanWord);

do anybody know the reason?

Above you have used a function call as the second argument attachEvent

The second argument to attachEvent is a function...

img.attachEvent("onclick",function(){alert{"aa");});

div.appendChild(img);
div.innerHTML+="some text";

img.onclick= function(){alert('aa')}

never did care for attachEvent.

Loose coupling between chunks of JavaScript and event delegation must
not be your thing, eh? It is relatively frequently that I attach more
than one window.onload handler to initialize javascript pieces that
deal with different parts of the page.
