How to resolve problems when you declare a variable in a function or jquery plugin too much.

simpleDeclareFunction.js

/** 
* As an example, I use jquery plugins Chosen. 
*/
$('#firstid').chosen({});
$('#secondid').chosen({});
$('#moreid').chosen({});

/**
* How to resolve : Get id attribute from tag select.
*/
$('select').each( function(i,v) {
	  $('#'+$(this).attr('id')).chosen({ width: '100%' });
});
