Use Js to change a buttons onclick value

Question

I have a button

<button id="buttonOne" onclick="pressOne()">Press</button>

i was wondering if it was possible using javascript to change the

onclick="pressOne()"

to

onclick="pressTwo()"

so the button would be

<button id="buttonOne" onclick="pressTwo()">Press</button>

Thanks!

It would be better to contain the condition which determines which logic to run within a single function. What governs which function should be executed on click? — Rory McCrossan

You can change it using this:

$("#buttonOne").attr("onclick","pressTwo()");

For example:

function pressOne() {
    $("#buttonOne").attr("onclick","pressTwo()");
}

You can do that like this :

document.getElementById("buttonOne").setAttribute("onclick","pressTwo()");

jsFiddle

But it would be better to add an other function which handle clicks :

<button id="buttonOne" onclick="onPress()">Press</button>

With the following javascript :

var pressOne = function() {
  ...
}

var pressTwo = function() {
  ...
}

function onPress() {
  if(..) {
    pressOne();
  } else {
    pressTwo();
  }
}
