Test if element with an input type text exists jquery

Question

I would like to test if an element exists but i cannot do it with $('#id')length > 0 because i am testing an input element which might not contain any characters and then it results in 0 even if it exists...

How can i test if this element exists??

What are you trying to achieve? If you are testing element exist to show/hide or any jQuery operations, then simply use $('#id').show() because jQuery internally will call the function only if it finds one or more matching elements. — Selvakumar Arumugam

length property is not returning the characters in the element. but the number of elements in the jQuery object. So you should be good to use length property in your case.

See it is not a typo in code, I think he wanted to test if an input elements has empty values.

@vega yes, it sounds that is not a typo, length of an id is weird. if ($("#id").text() != "")?

Do it like this, Demo on JsFiddle

With jQuery

$('#id').length > 0

With Javascript

if(document.getElementById('ID') != null)
{
    alert("Element found");
}

This is not correct as $('Anything') always returns jQuery object. It is never null. -1 >> jsfiddle.net/skram/RewrK <<
