AddID In JQuery?
Answer : ID is an attribute, you can set it with the attr function: $(element).attr('id', 'newID'); I'm not sure what you mean about adding IDs since an element can only have one identifier and this identifier must be unique. do you mean a method? $('div.foo').attr('id', 'foo123'); Just be careful that you don't set multiple elements to the same ID. Like this : var id = $('div.foo').attr('id'); $('div.foo').attr('id', id + ' id_adding'); get actual ID put actuel ID and add the new one
