How Does A JQuery Instance Appear As An Array When Called In Console.log?
Solution 1:
I believe they have something like that:
// Adding items to an object like an Array:
var myObject = {splice : Array.prototype.splice};
Array.prototype.push.call(myObject, 1, 10, "foo");
// Getting items from an object like an Array:
alert(Array.prototype.slice.call(myObject, 0));
console.log(myObject);
alert(myObject);
Solution 2:
The console makes it look like an array because it has array-like properties. It has length and n keys using integers.
Solution 3:
When you call jQuery()
you aren't passing any arguments to the function so it is returning an empty object. WHen you pass a selector as argument it creates an object of the elements that match the selector
Solution 4:
It returns an empty array, because it did nothing - array of elements affected.
Proper way to inspect would be
console.log(jQuery);
if you would do
console.log(jQuery('div'));
you will see that it returns array of elements.
Solution 5:
I think what you're trying to see are your object's properties. If that's the case, you're inadvertently converting the object into a string when you append it to another string. Use the ,
operator instead of +
to show the object properties instead of the "stringified" version of the object:
console.log('test with string concat: ', j);
