I have a jQuery object that is created via jQuery .find() as seen below...

var $mytable= $('#mytable');
var $myObject = $mytable.find("tbody tr");

This works great and creates a jQuery object of all the tr elements in the tbody. However, as I'm looping over the data, I need to be able to remove parts of the object as I go. For instance, if the above call returns a jQuery object named $myObject with a length of 10, and I want to remove the index 10, I thought I could just do $myObject.splice(10,1) and it would remove the element at index 10. However this doesn't seem to be working.

Any ideas why? Thank you!

UPDATE

I basically just want to be able to remove any element I want from $myObject as I loop through the data. I know it's zero based (bad example above I guess), was just trying to get my point across.

UPDATE

Okay, so I create the object using the find method on the table and at it's creation it's length is 24. As I loop over the object, when I hit an element I don't want I tried to use Array.prototype.splice.call($rows,x,1) where x represents the index to remove. Afterwards when I view the object in the console, it still has a length of 24.

  • @A1rPun $myObject.get().pop(); – A. Wolff Commented Dec 17, 2013 at 21:26
  • @A.Wolff I soon realised :) But the answer depends on what the asker is doing with the output. – A1rPun Commented Dec 17, 2013 at 21:29
  • It's difficult to give you a "best" answer since you're not telling us what you're doing this for. What do you want to do with this jQuery object after you've selected it? – Blazemonger Commented Dec 17, 2013 at 21:33
  • @Blazemonger I want to be able to remove elements from the object and have it re-indexed so if it has a length of 24, and I remove the data at index 15, it will show a new length of 23 – Phil Commented Dec 17, 2013 at 21:38

Use .not() to remove a single element, then loop through the jQuery object at your leisure:

var $myObject = $mytable.find('tbody tr').not(':eq(9)'); // zero-based

http://jsfiddle/mblase75/tLP87/

http://api.jquery./not/


Or if you might be removing more than one:

var $myObject = $mytable.find("tbody tr:lt(9)");

http://jsfiddle/mblase75/9evT8/

http://api.jquery./lt-selector/

splice is not part of the jQuery API, but you can apply native Array methods on jQuery collections by applying the prototype:

Array.prototype.splice.call($myObject, 9, 1); // 0-index

You can also use pop to remove the last item:

Array.prototype.pop.call($myObject);

This should also give you a correct length property.

splice is an array method, not a jQuery object method.

Try slice

Javascript uses zero-based arrays. This means that the final item in the array (i.e. the 10th item) will be at index 9.

$myObject[9]

So you need something like this:

$myObject.splice(9, 1);

This will remove the element from your existing array, and also return it.

You could also use filter :

var $myObject = $mytable.find("tbody tr").filter(':lt(9)');

You can use .remove to remove an element from the DOM.

So to remove the element at index 9 of the $myObject array, use:

$myObject.eq(9).remove();

If you want to keep the element that you are removing, you can also do:

var removedElement = $myObject.eq(9);
removedElement.detach();
