You can use the "Impact on weight" text fields on the "Combinations" tab of the product editor to set the weight of each combination. You can choose to set a base weight and then add weight differences or set the base weight to 0 and then set the exact weight for each combination.

yes, but in my themes doesnt change weight if i change combination with different weight

 

edit:

 

im change file

 

product.js

 

im put in function

addCombination(...,...,weight) 

and after 

var combination = []; 

this

combination['weight'] = weight;

 

and in 

function findCombination()

selectedCombination['weight'] = combination['weight'];
var fweight= selectedCombination['weight'];  
$('.whatever-box').html('<span>Hmotnost: '+fweight +'</span>');  

 .. and in .whatever-box i have: Undefined
