jquery: How to pass form element info to another function?

I am trying to do some things on a form element blur. The problem I'm having is passing the element's info such as ID, class, etc to a second function. I've simplified it down for this example:

function otherfunction() {
    var inputID = $(this).attr("id");
    alert(inputID);
}


$(".formelement").blur(function () { 

// Do some stuff here

otherfunction();

});

Of course, the alert box says that the inputID is undefined. How can I get the element's info passed to the otherfunction?

Pass the input as an argument:

function otherfunction(el) {
    var inputID = $(el).attr("id");
    alert(inputID);
}


$(".formelement").blur(function () {
    // Do some stuff here

    otherfunction(this);
});

Or, use Function.prototype.apply:

function otherfunction() {
    var inputID = $(this).attr("id");
    alert(inputID);
}


$(".formelement").blur(function () {
    // Do some stuff here

    otherfunction.apply(this);
});

Use $.proxy in case of:

$(".formelement").blur($.proxy(otherfunction, this));

And otherwise javascript's call or apply:

$(".formelement").blur(function () { 

    // Do some stuff here

    otherfunction.call(this); // or otherfunction.apply(this); 
});

I think u can use like this :

function otherfunction(obj) {
    var inputID = $(obj).attr("id");
    alert(inputID); }


$(".formelement").blur(function () { 

otherfunction($(this));

});
