Question

I’ve several custom widgets with dojo. and I am passing properties to constructor. What I want to know how to merge the default properties with the supplied params in constructor(params) ? jQuery has extend() do I need to use dojo.extend ? or dojo.hitch ?

Answer 1

dojo.mixin will do this. however, a widget does this automatically.

// from _WidgetBase.create(/*Object?*/params, /*DomNode|String?*/srcNodeRef)    
if(params){
  this.params = params;
  lang.mixin(this, params);
}

lang.mixin is dojo.mixin from dojo/_base/lang

var w = new CustomWidget({a:1,b:2}, node);
// w.a is 1
// w.b is 2
