This article describes how to use JavaScript arrays, multi-dimensional arrays, and objects in a hybrid manner. For more information about how to use JavaScript arrays and objects, see the following article, due to the weak check feature of JS, different types of variables can be stored in the JS array at the same time. For example, you can put numbers, strings, characters, objects, and other content in the same array. Objects can also do the same thing. The difference is that an object can speci

First, the PrimerTen years ago, there was an upstart who had three cars---Mercedes-Benz, BMW BMW, Audi Benz, and hired a driver to help him drive. But the nouveau riche is always a strange ride: After the Benz with the driver said "drive Mercedes!" "When he was in BMW, he said," Drive a BMW! "Take the Audi and say," Drive the car! ”。 You must say: this man is sick! Why don't you just say drive?!And when we

Js one-dimensional array, multi-dimensional array and Object Mixed use method, js dimension The main purpose of this article is to explain the mixed use of JavaScript arrays and objects. Due to the weak check feature of JS, different types of variables can be stored in the JS array at the same time, for example, you can place numbers, strings, characters, objects, and other content in the same array. Objects can also do the same thing. The difference is that an object can specify the alias of ea

First, Sort:1. Using the method sort () to sort the list permanently2. Use function sorted () to sort the list temporarilyNote: reverse () does not refer to arranging list elements in the opposite order of alphabetical order, but simply reversing the row of list elementsColumn order:Cars = ['BMW','Audi','Toyota','Subaru']Print(Cars) cars.reverse ()Print(Cars) ['BMW','Audi','Toyota','Subaru']['Subaru','Toyot

FALSE.var x=truevar y=falseBoolean is commonly used in conditional tests. You'll learn more about conditional testing in later chapters of this tutorial.JavaScript arraysThe following code creates an array named cars:var cars=new Array ();Cars[0]= "Audi";Cars[1]= "BMW";Cars[2]= "Volvo";or (condensed array):var cars=new Array ("Audi", "BMW", "Volvo");or (literal array):Instancevar cars=["

With respect to an array of string types, the array element does not need to be added "" Today, in writing swing, for a quick layout, you need to create a string layout array as shown: Careful readers may find that the array elements in this border array are not in "", and we know in the learning array that when we define a String array, the elements of the array need to be included in "", for example, we define an array string[]car={"BMW", "Mercedes", " A
