How to find if element with specific id exists or not

Question

In my JavaScript I want to check whether the element with specific id is exist or not, I tried it with 2 ways

1).

var myEle = document.getElementByI         


        

Answer 1

document.getElementById('yourId')

is the correct way.

the document refers the HTML document that is loaded in the DOM.

and it searches the id using the function getElementById() which takes a parameter of the id of an element

Solution will be :

var elem = (document.getElementById('myElement'))? document.getElementById('myElement').value : '';

/* this will assign a value or give you and empty string */
