adding event

[bakhanbeigi]

How can I add an event in javascript ?
I want add a event for elements when an object droped on it do something

could you go into more detail such as what will be the receiving element and what will be dragged and dropped?

I have a function like this
function drag(object_id){
//that make drag an element
}

I want when this dragble element droped on another element for example on a div page do something (event work)
