Insert a function into javascript object

Question

I tried to insert a function into javascript object but I get

undefined

This is supposed to return a message into div.

I would like to do it the first way, but here is the both way I tried :

var errorMessage = {
     empty: function(message){"<div class='field'><div class='csv'><span class='icon'></span><label class='manual' id='error-message'>" + message + "</label></div></div>"
    }
 };

console.log(errorMessage.empty("Hello"));

I also try this way

function errorMessage(message){
    "<div class='field'><div class='csv'><span class='icon'></span><label class='manual' id='error-message'>" + message + "</label></div></div>"

}

console.log(errorMessage("hello"))

What do you expect the function to do? It's literally just a string literal in a function. — Andrew Li

You need a return of the value literally.

The return statement ends function execution and specifies a value to be returned to the function caller.

var errorMessage = {
        empty: function (message) {
            return "<div class='field'><div class='csv'><span class='icon'></span><label class='manual' id='error-message'>" + message + "</label></div></div>";
        }
    };

console.log(errorMessage.empty("Hello"));

Your function needs to return the value

var errorMessage = {
     empty: function(message){
        return "<div class='field'><div class='csv'><span class='icon'></span><label class='manual' id='error-message'>" + message + "</label></div></div>";
    }
 };

console.log(errorMessage.empty("Hello"));
