(2) module Mode

The module mode is based on the object literal. The most basic form of object literal is:

VaR car = {};

Implementation of the module Mode Based on Object literal volume:

 var Car = {        color: ‘white‘,        getCarPrice: function () {        },        getCarColor: function () {            console.log(this.color);        }    };    Car.getCarColor();

In the module mode, the private and public methods and variables are implemented.

var testModule = function(){        var privateValue = 1;        var publicValue = 2;        var privateMethod = function(){};        var publicMethod = function(){            console.log(privateValue);        };        var service = {            publicMethod:publicMethod,            publicValue:publicValue        };        return service;    };    testModule().publicMethod();//1    testModule().privateMethod();//undefined is not a function    testModule().privateValue;//no error , just console nothing

Continue to modify

VaR testmodule = (function () {var privatevalue = 1; var publicvalue = 2; var privatemethod = function () {}; var publicmethod = function () {console. log (publicvalue) ;}; var service ={ publicmethod: publicmethod, publicvalue: publicvalue }; return service ;}) (); testmodule. publicmethod (); // 2 testmodule. publicvalue = 3; testmodule. publicmethod (); // 2 cannot be modified,

If you want to modify internal variables, you can only modify them by providing external methods.

var testModule = (function(){        var privateValue = 1;        var publicValue = 2;        var privateMethod = function(){};        var publicMethod = function(){            console.log(publicValue);        };        var setPublicValue = function(value){            publicValue = value;        };        var service = {            publicMethod:publicMethod,            publicValue:publicValue,            setPublicValue:setPublicValue        };        return service;    })();    testModule.publicMethod();//2    testModule.setPublicValue(4);    testModule.publicMethod();//4
