How to get the caller event and dom element id

javascript

Solution

An event object is passed to the Hello function automatically. You need to receive it as an argument and then do some cross-platform work to grab the element. A JS framework will help you out here.

function Hello(e){
    var caller = e.target || e.srcElement;
    console.log( caller );
}

EDIT +1 Andrew's comment below. Use addEventListener and attachEvent for best practice.

Problem

``` <script> function Hello(){ var caller = arguments.callee.caller; alert( caller ); } </script> <input type="button" id="btnHello" value="Hello" onclick="Hello()" /> ``` How to get the button id from the the Hello function above with out passing the any argument in the Hello function
