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.

Answer 3

focus is a function and must be called like one, change your code to look like:

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

For reference, see focus documentation .
