I'm trying, without success, to do like in other languages which the object can have a default return value, but yet has its methods. Like:
var o = {
this: "MyReturn",
SampleString: "My String",
MyMethod1: function() {},
MyMethod2: function() {},
}
Then, my output should be:
> o
< "MyReturn"
> o.SampleString
< "My String"
> o.MyMethod1()
< function() {}
Is it possible to do? (In a way that doesn't use Prototype, or it will conflict with my code)
This is not possible as-such. o would always be an object. The closest you could come would be custom toString method and casting o to a string or making the object a Function and call o like o().
Here are some option that get as close as JavaScript can get.
var o = function(){
return "MyReturn";
};
o.SampleString = "My String";
o.MyMethod1 = function() {};
o.MyMethod2 = function() {};
Output
> o()
< "MyReturn"
> o.SampleString
< "My String"
> o.MyMethod1()
< function() {}
var o = {
toString: function(){return "MyReturn";},
SampleString: "My String",
MyMethod1: function() {},
MyMethod2: function() {},
}
Output
> String(o)
< "MyReturn"
> o.SampleString
< "My String"
> o.MyMethod1()
< function() {}
In this second option, String(o) can be substituted for ""+o, o.toString(), or anthing that causes type-casting to a string.
You are looking for the toString() method.
Every object has a toString() method that is automatically called when the object is to be represented as a text value or when an object is referred to in a manner in which a string is expected. By default, the toString() method is inherited by every object descended from Object. If this method is not overridden in a custom object, toString() returns "[object type]", where type is the object type. Source: MDN Object.prototype.toString()
var o = {
SampleString: "My String",
MyMethod1: function() {},
MyMethod2: function() {}
};
o.toString = function () {
return "MyReturn";
};
alert(o);
// MyReturn;
alert(o.SampleString);
// My String;
alert(o.MyMethod1);
// function () {}
I think the closest is this
var o = {name:"myName"};
o.toString = function(){return o.name}
console.log(o+"");
