var model = {
test:function(){console.log("hello")},
show: test() //ReferenceError: test is not defined
}
I want to have a key inside model object to hold a function. Not sure why it gets undefined error.

2You can't reference the contents of an object literal from inside while it's "under construction". You have to use a separate statement.Pointy– Pointy2015-02-19 17:53:56 +00:00Commented Feb 19, 2015 at 17:53

You mean I can only call this function outside of object?user2634156– user26341562015-02-19 17:55:27 +00:00Commented Feb 19, 2015 at 17:55

Yes. There's just no way to do it in JavaScript all inside a single object literal.Pointy– Pointy2015-02-19 17:59:51 +00:00Commented Feb 19, 2015 at 17:59

Hope it helps .
var model = {
test: function() {
alert("hello")
},
show: function() {
return this.test();
}
}
model.test();
model.show();use key show as a function, return test from it.

I know this is a duplicate but I can't find a good one. You have to do something like this:
var model = {
test:function(){console.log("hello")},
};
model.show = model.test();
If you want to make it less ... primitive, I guess, you can write a constructor function to encapsulate that stuff, or perhaps a "factory"-like function to do so.
