How to print structured array and push value in array

Question

I am new to JQuery. I am here to learn JQuery fundamentals and serious to know how array works in jQuery.

<!DOCTYPE html>
<html>
<head>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">
    <style>
  div { color:blue; }
  span { color:red; }
</style>
    <script src="jquery-latest.js"></script>
</head>
<body>

<div id="myDiv"></div>

<script>
$(document).ready(function() {

    var testArray = ["test1","test2","test3","test4"];
    var new_array=[];
    var vPool="";

    /*i tried but this pushing code dosen't work*/

   //pushing values in new_array
    $("new_array").push({"test1","test2","test3","test4"});

    //fetching the values of new_array 
    $.each(new_array, function(i, val) {
      vPool+=val + "<br />";
    });
    $('#myDiv').html(vPool);--->
    //vPool="";

    /*But i tried this code it work fine */

    //fetching the values of new_array 
    $.each(testArray, function(i, val) {
      vPool+=val + "<br />";
    });
    $('#myDiv').html(vPool); 
    //vPool="";

});
</script>

</body>
</html>

And I want to know how to print structured array like we print in PHP:

echo "<pre>";
print_r($array);

Are you trying to print in order to debug ? If so use console.log(arr) and look at the console. — Denys Séguret

Array is part of JavaScript. jQuery is a library written in JavaScript. — nhahtdh

Remove the $("") arround new_array. Also you are pushing an object that is defined incorrect. And the push() function has nothing to do with jQuery, it is pure JavaScript.

About the printing of the whole array you should try console.log() in Chrome or Firefox with installed Firebug extension.

$(document).ready(function() {

    var testArray = ["test1","test2","test3","test4"];
    var new_array=[];
    var vPool="";

    /*i tried but this pushing code dosen't work*/

    //pushing values in new_array
    new_array.push("test1","test2","test3","test4");
    console.log(new_array);

    $.each(new_array, function(i, val) {
        vPool+=val + "<br />";
        console.log(val);
    });

});

The push() function returns the new length of the array.
