jquery each loop call function with parameter

Question

I would like to use an array of functions ins in a jquery each loop and pass parameters to sad functions.

Something like what is below.

var test = function(x) { return x+1;};
var test2 = function (x) { return x+2};
var mark = [test,test2]; 

mark.each(function() { $(this)(3)});

expected result
4
5

how do I achieve this.

Working example of answer

var test = function(x) { return x+1;};
var test2 = function (x) { return x+2;};
var mark = [test,test2]; $.each(mark, function () {
  console.log(  this(3));
});

Did you try this(3)

$.each(mark, function () {
    this(3);
});

also note, you need $.each to iterate and array not mark.each as .each is available only on jQuery object.

@Archer it works for me. I have updated my question to reflect it

How bizarre. I did it in the console on this page and it returned the functions as object references. When I did it in jsfiddle it worked. Oh well! +1 :)

you would need to put your array as the first parameter of your $.each() method

there are 2 different types of jQuery each() methods

the first iterates over both objects and arrays:

http://api.jquery.com/jQuery.each/

// array
$.each([ 52, 97 ], function( index, value ) {
   alert( index + ": " + value );
});

// object
var obj = {
      "flammable": "inflammable",
      "duh": "no duh"
};
$.each( obj, function( key, value ) {
      alert( key + ": " + value );
});

the second iterates over a collection of elements

http://api.jquery.com/each/

<ul>
    <li>foo</li>
    <li>bar</li>
</ul>

selector each look like this

// collection of elements
$("li").each(function( index ) {
     console.log( index + ": " + $( this ).text() );
});
