Another method for passing object parameters to methods in JavaScript (Object literal volume)

Method functions:

Function Sendmessage (smsg, oobj ){
If (Arguments. Length =   2 ){
Oobj. handlemsg (smsg );
Oobj. Test ();
} Else {
Alert (smsg );
};
}

Sendmessage ("Hello world!");

 

Common method transfer:

Function OBJ (){
}

OBJ. Prototype. handlemsg =   Function (Smsg ){
Alert ( " This is a custom message: "   + Smsg );
};
OBJ. Prototype. Test =   Function (){
Alert ( " Test " );
};

Sendmessage ("Asdfsdasdfdfa",NewOBJ );

Another method (Object literal):

// Two parameters are passed in, and the second is an object.
// This object has a method handlemsg ()
Sendmessage ( " How are you? " ,{
Handlemsg: Function (Smsg ){
Alert ( " This is a custom message: "   + Smsg );
},
Test: Function (){
Alert ( " Test " );
}
});

I am not very familiar with the transfer of such methods, but I can. Give me some advice

Supplement:

This method is called in simple JavaScript.Is the object literal

How to create an object:
VaR OBJ =   New Object ();
OBJ. VaR   =   " ASDF " ;
OBJ. Click =   Function (){
Alert ( " Asdfas " );
};
Equivalent
VaR OBJ = {
VAL: " ASDF " ,
Click: Function (){
Alert ( " Asdfa " );
}
};

In this way, we can understand the above usage.
