javascript - Dynamic if statement using string variable -

i have object in javascript starts looking this:

variable = {1: 'no', 2: 'no', 3: 'no'}  

and dynamically changes based on user , updates this, example:

variabel = {1: 'yes', 2: 'no', 3: 'yes'}  

i want dynamically build if statement keys have yes this:

if (feature.properties.1.indexof(variable.1)!=-1 && feature.properties.3.indexof(variable.3)!=-1)   

is there way this? tried looping on object dynamically build string statement , attempted unstring used in if statement had no luck. appreciated.

var success = true;  (var in variable) {    if (feature.properties[i].indexof(variable[i]) === -1) {        success = false;        break;    } }  // evaluate success here
