JQUERY Get Element By parameter ID

Question

just want to know what is the equivalent syntax of this to jquery.

var elm_id = \'my_id\';
var elm = document.getElementById(elm_id);

thank

Answer 1

var elm_id = 'my_id'; 
var elm = $('#' + elm_id)[0];

Adding the [0] gets the actual node which is what document.getElementById(elm_id); returns.
