Example Analysis of JavaScript object, object property and object method
This article mainly introduces the JavaScript object, object properties, object method example analysis, the article introduces in great detail, has a certain reference value, interested friends must read it!
The JavaScript variable is a container for data values.
This code assigns a single value (porsche) to a variable named car:
Var car = "porsche"
Objects are also variables. But the object contains many values.
This code assigns multiple values (porsche, 911, white) to a variable named car:
Var car = {type: "porsche", model: "911", color: "white"}
Values are written as name: value pairs (names and values are separated by colons).
The JavaScript object is a container for named values.
Object attribute
(in the JavaScript object) name: value pairs are called properties.
Var person = {firstName: "Bill", lastName: "Gates", age:62, eyeColor: "blue"}
Attribute value
FirstName Bill
LastName Gates
Age 62
EyeColor blue
Object method
Objects can also have methods.
Method is an action performed on an object.
Method is stored in the property as a function definition.
Attribute value
FirstName Bill
LastName Gates
Age 62
EyeColor blue
FullName function () {return this.firstName + "" + this.lastName;}
Method is a function that is stored as an attribute.
Example
Var person = {
FirstName: "Bill"
LastName: "Gates"
Id: 678
FullName: function () {
Return this.firstName + "" + this.lastName
}
}
