How do I get first element rather than using 0 in jQuery

Question

I m new to jQuery  apologies if this is a silly question   When I use it find an element using the id  I know theres always one match and in order to access it I would use the index  0   Is there a better way of doing this  For e g   var gridHeader       grid GridHeader   0

You can use  get 0  as well but   you shouldn t need to do that with an element found by ID  that should always be unique   I m hoping this is just an oversight in the example   if this is the case on your actual page  you ll need to fix it so your IDs are unique  and use a class  or another attribute  instead    get    like  0   gets the DOM element  if you want a jQuery object use  eq 0  or  first   instead

With the assumption that there s only one element        grid GridHeader   0       grid GridHeader   get 0       grid GridHeader   get        are all equivalent  returning the single underlying element   From the jQuery source code  you can see that get 0   under the covers  essentially does the same thing as the  0  approach       Return just the object    num  lt  0   this slice num   0     this  num
