Javascript getting property value

Question

My problem is:

Works:

console.log(variable[apple]);

variable: {
  apple : "xxx"
}

Not working:

console.log(variable.element[apple]);

variable: {
  element: {
    apple: "xxx"
  }
}

element is not undefined. Any idea?

This `req.body` should be syntax error. Also `[apple]` should be in quotes — Rajesh, Feb 05 '18 at 10:10

this req.body is just an example... but okay, I change the variable names — HowToTellAChild, Feb 05 '18 at 10:11

Dear Andreas! My desired behaviour is to wok this statement: console.log(variable.element[apple]); My specific problem is: This statement above is not working! You don't help in my problem, if you just insert quotations. — HowToTellAChild, Feb 05 '18 at 10:16

@Andreas if you want to really help me, or to others, then ask, if you don't understand something. — HowToTellAChild, Feb 05 '18 at 10:42

variable: {  //this is a code block labeled "variable"
  element: {  //this is a code block labeled "element"
    apple: "xxx"  //this is an expression "xxx" labeled as "apple"
  }
}

But there's no variable in your code. Read up about labeled statements

You probably mean

var variable = {  //now this is a variable containing an object
  element: {  //and these are properties of that object
    apple: "xxx"  
  }
}

console.log(variable.element.apple);
