how to access array in jquery

The array is somewhat like this :

[[Object { button={...}}, 
  Object { input={...}}, 
  Object { checkbox={...}}, 
  Object { textarea={...}}],
 [Object { textarea={...}}]
]

In the curly brackets i have set some properties like color,value,type etc.
What i want is to get the each object of an array and check through the properties like type of an object and then call a function to perform further things. Just like in PHP we use :

foreach($a as $b){
 // and then do something here ..
};

Kindly help me through and i hope everyone can understand what i am trying to say.

// var i is the counter for page numbers   
function pagination(i) {
  alert(i);
  i--;
  //page is array 

  var result = page;
  //console.log(result[i]);
  var $currentElem;
  $(result[i]).each(function() {

    currentElem = $(this);
    console.log(currentElem);

  });
}

.each is used when you're looping over the elements of a jQuery collection. To loop over the contents of an array or object. use $.each():

$.each(result[i], function(n, currentElem) {
    console.log(currentElem);
});

And you shouldn't use $(this) unless this is a DOM element. If it's just a Javascript object, wrapping it in a jQuery object is unnecessary.

You can access the properties using the normal Javascript variable.propertyname syntax, e.g. currentElem.button and currentElem.button.color. To append elements to your view, you can do something like:

var button = currentElem.button;
$("<button>", {
    value: button.value,
    name: button.name,
    css: {
        color: button.color,
        width: button.width,
        backgroundColor: button.backgroundcolor
    }
}).appendTo($("#buttonDiv");

To iterate you can use for(in) or in jquery $.each.

for(var i in array) {
    console.log(array[i]);
}
