jquery convert object to array

Share this article

Some options for converting a jQuery object into an array. Also you can use a jQuery object much like an array. For example:

obj = $('p'); // Get all paragraphs into a jQuery object
  for (i = 0; i < obj.length; i++) {
    // Do something with obj[i]
  }
As you can see, jQuery objects have .length and []. But, .pop() and .reverse() are missing. And you may want to pass the array to a function that expects a native array. So do this:
obj = $('p'); // Get all paragraphs
  a = $.makeArray(obj); // One way to do it
  a = obj.toArray();  // The other way
also try:
$.each(piv, function(name, value)
 {
    console.log(name, value);
 });

 or this

 for (var key in piv) {
     // var obj = piv[key];
     console.log(key, piv[key]);
  }

Frequently Asked Questions (FAQs) about Converting jQuery Objects to Arrays

What is the difference between jQuery.makeArray() and toArray() in jQuery?

Both jQuery.makeArray() and toArray() are used to convert an object into an array in jQuery. However, there is a subtle difference between the two. jQuery.makeArray() is a jQuery utility function that takes an array-like object and transforms it into a true JavaScript array. On the other hand, toArray() is a method that belongs to the jQuery object prototype, and it returns a JavaScript array of the selected DOM elements.

How can I convert a JavaScript object to an array using jQuery?

var obj = { "One": 1, "Two": 2, "Three": 3, "Four": 4 };
var arr = $.map(obj, function(value, index) {
return [value];
});
console.log(arr); // Output: [1, 2, 3, 4]
