Adding dojo parameter to exsisting field

Question

I have a form created in php and I want to add some attributes to it from js dojo.

I can retrive the textfield by it's id (dojo.byId), but how to add the placeholder attribute to the node without creating a new one and replacing the previous field?

Answer 1

dojo.byId("textbox1").placeholder = "I'm your placeholder";
