check if element is inserted on page

Question

Possible Duplicate:
Is there an “exists” function for jQuery

Is there a better way to check if the element is already inserted on page? I'm currently doing this and is working fine, but doesn't seem for me to be the best/fast way

$(element).closest('body').length > 0

Thanks.

Edit:

I doesn't need to know if my element exists, I need to know if it's on page.

@JMax this is a different question. – DiogoDoreto Nov 28 '11 at 14:48 — DiogoDoreto, Nov 28 '11 at 14:48

You can use jQuery's built in .has function so your code should look something like:

$('body').has(element)

Thanks for answering, but my element doesn't have an id. – DiogoDoreto Nov 28 '11 at 14:47

Perhaps jQuery's .has() would be of more use? http://api.jquery.com/has/ – Gerard Nov 28 '11 at 14:50
and invert what I'm doing, right? like this: `$('body').has(element)`? – DiogoDoreto Nov 28 '11 at 14:54
Yes, it works and is better for reading :) Can you edit your answer? – DiogoDoreto Nov 28 '11 at 15:03

Try this :

$(element, 'body').size() > 0

It will fetch for the element within the body.

What you are doing is searching for element "body". It's not what you are looking for

$(element).length > 0

check whether an element exists

Thanks for your answer, but I already have _the element_ on var. I need to know if it's inserted on page or is detached. – DiogoDoreto Nov 28 '11 at 14:46

if ( $('element-selector-here').length )
{
    // element exist
}
else 
{
    // element doesn't exist
}
