JQuery focus an element

Question

In javascript the following works to give focus to the edit_2 input box:

document.getElementById("edit_2").focus(); 

However using Jquery this does not:

$("#edit_2").focus; 

Answer 1

You are calling a method, so:

$("#edit_2").focus; 

should be

$("#edit_2").focus(); 

EDIT: If you are wondering why the first line was not counted as a syntax error, it's because it is a correct statement saying "get the function focus" (and do nothing with it).

Answer 2

Your statement

$("#edit_2").focus 

is not calling the function 'focus', in order to call the function you have to use the syntax 'focus()'

try

j$("#some_id").focus() 

It is working fine.

EDIT Your statement '$("#edit_2").focus' is not throwing an error because it just returns a reference to the function 'focus', but it does not call the function.
