向对象添加属性

Question

I wrote this code and it`s simple , i have an empty object which will contain some other objects as properties , but the object stays empty and don`t add the needed properties ..

let buildProfileClientValidator = function(form , rules){

    let elements = {};

    function init(){
       //Some code that works fine
       addElement(elementName , elementType);
       addElement(elementName , elementType);

        //the elements object should now have some other objects as properties  
        //but it`s empty !!!!
        console.log(elements);
     }

     function addElement(elementName , elementType){
        //this condition works fine 
        if( !elementExist(elementName) ){
        //console.log(elementName , elementType); also works fine -> the values of  elementName , elementType are present
        elements[elementName] = {
            type  : elementType,
            value : '',
            rules : (rules[elementName] == undefined) ? '' :  rules[elementName].split('|')
         };
       }
     }
 }

so what i`m missing ?!

Answer 1

After examining your code, but not knowing how buildProfileClientValidator gets called (and specifically what the rules parameter is), I can trace the problem to this line:

 (rules[elementName] === undefined) ? '' :  rules[elementName].split('|')

I have modified your code (to make it testable) in the following fiddle ( https://jsfiddle.net/hssbsL19/40/ ) and when I replace that line with a static value, the code works.
