javascript - Change attributes of a DOM element when it appears -

is there way change attribute of dom element created? have input (has id) created plugin. need change placeholder of input when appears.

i.e.

$("#token-input_sample").live("attr","placeholder","place"); 

code above doesn't work.

on() should used bind events elements exist now, or in future. manipulate properties or attributes of elements, should use prop() function:

$('#token-input_sample').prop('placeholder', 'place');
