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

I think what you're looking for is

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

Answer 2

Selecting by ID in jquery is done with the # character:

$('#my_id')

I invite you to read the documentation about jQuery Selectors

Answer 3

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.

Answer 4

var elem_id="my_id";
$("#"+elem_id);

Answer 5

You need this (I think):

$('#my_id')

Answer 6

In jquery the following code is being written as:

var elm = $("#my_id");

OR you can write as:

var elm_id = 'my_id';
var elm = $("#" + elm_id);
