Question

For example, the following selects a division with id=’2′:

row = $('body').find('#2'); 

How do I do something like this:

row_id = 5; row = $('body').find(row_id); 

The above syntax produces an error. I checked the jQuery documentation and answers here without success.

Answer 1

row = $('body').find('#' + row_id); 

More importantly doing the additional body.find has no impact on performance. The proper way to do this is simply:

row = $('#' + row_id);
