Arrays are defined in four ways
Using the constructor:
var a = new Array();
var b = new Array(10);
var c = new Array("first", "second", "third");
Or array direct quantity:
var d = ["first", "second", "third"];
Extension:
function ObjStory(id,biaoti,author,type) // Declare an object
{
this.ID = id;
this.Biaoti= biaoti;
this.Author= author;
this.Type = type;
}
var arr = new Array();// Declare an array to store header information
var writer= new ObjStory(11, 'Everybody go to see the sea ', 'Li Dadan ', 'Literature and art ');// Declare an object
arr[0]=writer;// To add an object to a collection
Another method:
var Array=[];
Array. push (new ObjStory (12, 'Let's see the sea', 'Li Dadan', 'Literature and art'));
Array. push (new ObjStory (14, 'Let's see the sky', 'Li Xiaodan', 'Literature and art'));
