javascript - I need to call a parent property from child object in an object literal

Question

I tried to call from child object a parent attribute

var parentObj = {  
   attr1:1,  
   attr2:2,   
   childObj:{  
      method1:function(){  
         return this.attr1 * this.attr2;  
      }  
   }  
}

but it doesn't work.

Answer 1

Try referencing parentObj directly:

var parentObj = {  
   attr1: 1,  
   attr2: 2,   
   childObj: {  
      method1: function () {  
         return parentObj.attr1 * parentObj.attr2;  
      }  
   }  
}
