![]() Here we discuss the basic concept, syntax, working, and examples of javascript static method.Introduction to Programming Using Java Version 7.0, August 2014ĭavid J. This is a guide to JavaScript Static Method. For example ClassName.Static-method-name-to-be=called() Recommended Articles So basically static method does not require the instance to access them we can directly access them by the class name within they belong. Return "calling static method from constructor." Return "calling static method from non static method"Ĭalling a static method from the constructor.ĭocument.writeln (()) To show the static method with the same name. Here are some of the examples of javascript static method given below: Example #1 Below is the example to show how to use this with the static keyword. Getter and setter accessors are also introduced in ES5 and this can be used with the static keyword. So we can have subclass to a parent class and any method which we declare in the parent class which will available in the subclass as well. JavaScript also has the introduction of classes in ES6 so now we can utilize the static method, constructors, super calls to parent and inheritance which will make the interoperability much easier for the developer. ![]() 'static methed called using constructor property.' 'static method called using class name.'Ĭonsole.log(()) For this, we can go with either of the two approachġ) classname.static_method_name() : By using the class nameĢ) _method_name() : Or by using the constructor property.Ĭonsole.log(StaticMethodCallDemo2.staticMethodOne()) Return this.staticMethod() + ' static method two' īut what if we want to call a static method from the non-static method. Return 'Static method one is called from ' In order to call a static method from another static method, we can use ‘this’ keyword. Nonstatic methods can easily access any static and any static variable without the instance of class. Whereas in the case of non-static methods they do have any static keyword along with the method name and if we want to work with non-static methods then we need to create the object of that class because it belongs to the class only in which it is declared.The static method doesn’t know which instance’s variable value to use. The static method can’t refer to any instance variables of the class. Also, the static method cannot use the nonstatic instance variable.The static method also cannot see the instance variable state so if we try to call the nonstatic method from the static method compiler will complain. ![]() On-static methods use instance variable state to affect their behavior.
