sending vars to a function on DOM event

[basher400]

Hi

I don't have access to the body of the page, only to it's javascript.
I need to call a function when a user pastes something on a certain element.
I need to send a var to that function.

this is what I came up with:

var myVar='342';

myElement.onpaste = function(myVar) {
	alert(myVar);
}

"myVar" in the alert comes in as "undefined", what am I doing wrong ?

myVar is a global variable, so you don't need to include that in the function definition:

var myVar='342';

myElement.onpaste = function() {
	alert(myVar);
};

Or if you do not want to use global variables, try out function closures:

function getPasteHandler() {
  var handler = arguments[0];
  var args = Array.prototype.slice.call(arguments, 1);

  return function() {
    return handler.apply(this, args);
  };
}

myElement.onpaste = getPasteHandler(function(a, b) {
  alert(a); // alerts 1
  alert(b); // alerts 2
}, 1, 2);
