Number
length
Specifies the number of arguments expected by the function.
Methods Summary
void
apply()
Applies the method of another object in the context of a different object (the calling object); arguments can be passed as an Array object.
void
bind()
Creates a new function which, when called, itself calls this function in the context of the provided value, with a given sequence of arguments preceding any provided when the new function was called.
void
call()
Calls (executes) a method of another object in the context of a different object (the calling object); arguments can be passed as they are.
String
toString()
Returns a string representing the source code of the function.
Property Details
constructor
Specifies the function that creates an object's prototype.
function Tree(name) {
this.name = name;
}
theTree = new Tree("Redwood");
console.log("theTree.constructor is " + theTree.constructor);
length
Specifies the number of arguments expected by the function.
function addNumbers(x, y){
if (addNumbers.length == 2) {
return (x + y);
} else
return 0;
}
Methods Details
apply()
Applies the method of another object in the context of a different object (the calling object); arguments can be passed as an Array object.
function book(name, author) {
this.name = name;
this.author = author;
}
function book_with_topic(name, author, topic) {
this.topic = topic;
book.apply(this, arguments);
}
book_with_topic.prototype = new book();
var aBook = new book_with_topic("name","author","topic");
bind()
Creates a new function which, when called, itself calls this function in the context of the provided value, with a given sequence of arguments preceding any provided when the new function was called.
var x = 9,
module = {
getX: function() {
return this.x;
},
x: 81
};
// "module.getX()" called, "module" is "this", "module.x" is returned
module.getX(); // > 81
// "getX()" called, "this" is global, "x" is returned
getX(); // > 9
// store a reference with "module" bound as "this"
var boundGetX = getX.bind(module);
// "boundGetX()" called, "module" is "this" again, "module.x" is returned
boundGetX(); // > 81
call()
Calls (executes) a method of another object in the context of a different object (the calling object); arguments can be passed as they are.
function book(name) {
this.name = name;
}
function book_with_author(name, author) {
this.author = author;
book.call(this, name);
}
book_with_author.prototype = new book();
var aBook = new book_with_author("name","author");
toString()
Returns a string representing the source code of the function. Overrides the Object.toString method.
function printHello() {
return "Hello";
}
application.output(printHello.toString());
