javascript typeof class name

This article mainly introduces the class Array objects in JavaScript. an object is not created by the Array constructor and still presents the behavior of an Array. in this case, these objects are called "class array objects". For more information, see JavaScript. an array is a special object whose property

'); } return " -0-"; }); The Inherits method is similar to the Java extends. The Uber method is similar to the Java super. It makes a method call the method of the parent class (changing the name to avoid conflicts with reserved words). We can write this. Copy Code code as follows: Myzparenizor = new Zparenizor (0); myString = Myzparenizor.tostring (); This time, mys

defined while defining "class" in JavaScript. Using constructors JavaScript uses classes in the same way as C #, and the new keyword follows the constructor. var p = new person (); Defining Properties and methods Now that we have defined the person class, you can add some properties and methods to th

process, we have a wonderful name: Class instantiation. The newly created object will have all the attributes and methods defined by the class. In the traditional class-based language, we can do this: public class Shape {private int height;private int width;public Shape(int

immediately delete the original value's object form.For example:var num = 123; NUM.ABC = "a"; Num.abc = undefined　and a chestnut to digest and digest.var str = "abc"; str + = 1; var test = typeof (str); if (test.length = = 6) {test.sign = "typeof return result may be string";} Doucment.write (test.sign);　　　See what the final output is? A rough look at Test is a string, just good length is 6, print "

I have been unemployed at school for one and a half months. I haven't found an internship yet. It's a tragedy and it hurts. cookie. js has changed to the pure javascript version. For future projects, I only need to add a function to get all the cookie key values on the page. The function is assembled by analyzing the document. cookie string.

The function is assembled by analyzing the document. cookie string.Review the operations on cookies in javascript: You can use document. cookie = "userId = 111"; to add a cookie.The full version can be used:Document. cookie = "userId = 111; domain = .google.com; path = \; secure = secure; expire =" + date. toGMTString ();You can set the cookie expiration time, domain name, and path.You only need to delete i

Copy Code code as follows: function class name (parameter table) { this. property; ...... this. function; } In this way, functions and data members are all using the "this." To achieve. We define a simple class student and then construct it and implement an output function. Copy Code code as follows: (Hey, it's to

Some time ago, after learning "ajax self-taught manual", I realized that javascript can still be written like this. I have learned the concepts of classes in Java, C #, and VB, and classes have functions such as inheritance, encapsulation, and polymorphism. Javascript is not an object-oriented language, but an explanatory language. But we can also use JavaScript
