Syntax

Parameters

Return

An Array object.

jQuery.makeArray( object ) ExampleTop

Return a JavaScript Array object created from an array-like object.

In the example below when we press the button the first time we create a variable from a node list and test to see if it is an array using the jQuery.isArray() type utility method which returns false.

We then create another variable from the first variable using the jQuery.makeArray( object ) general utility method. We then test this variable against the jQuery.isArray() type utility method which returns true.

$(function(){
  $('#btn1').one('click', function(){
    var pElements = document.getElementsByTagName('p');
    $('#div1').append('Is pElements an Array object? ' +  $.isArray( pElements ) + '<br>');
    var ourArray = jQuery.makeArray(pElements);
    $('#div1').append('Is ourArray an Array object? ' +  $.isArray( ourArray ) + '<br>');
  });
});
