ES3.1 Draft: 11 June 2008 version available

[André Rømcke]

Hi, and thanks for any work on making ES3 better while we wait for ES4!


One thing I miss form the targeted additions part of the spec is:
function.bindEvent aka function.bindEventListener

The difference from function.bind is that binded arguments are appended
after instead of before the arguments when called.

Example code for function.bind and function.bindEvent (where arguments is
a true array):


function.bind = function()
{
    // Binds arguments to a function, so when you call the returned
wrapper function,
    // arguments are intact and arguments passed to the wrapper function
is appended.
    // first argument is 'this' and the rest is arguments
    var args = arguments, __fn = this, __object = args.shift();
    return function(){ return __fn.apply(__object, args.concat(arguments))};
};

function.bindEvent = function()
{
    // Same as bind, but prepends the arguments to the wrapper function
    var args = arguments, __fn = this, __object = args.shift();
    return function(){ return __fn.apply(__object, arguments.concat(args))};
};
