How to handle multiple event in web control using javascript for ex handling onpaste and on keyup event in textarea

Answer 1

There’s no special trick to assigning different event handlers to an element, just define them as you would:

var tArea = document.getElementById("myTextArea");

// Define `onpaste` handler - note that Opera doesn't support `onpaste`
tArea.onpaste = function (evt) {
}

// Define `onkeyup` handler
tArea.onkeyup = function (evt) {
}

If you want to assign multiple functions to the same event, you need to use attachEvent for IE and addEventListener for other browsers.
