learn javascript for unity

WedgeLao Yao Write this note at the beginning said: "Learn JS, do not understand the event mechanism, the basic can be said to learn JS, is the white school."I am very ashamed to see this sentence, if I understand the event mechanism, I may not order this note, and now I am the one who learned.Re-start to look at themselves, engaged in web front-end development This job has been more than half a year, never

Original: Learn JavaScript from the beginning (11)--object typeI. Type of ObjectAn object is a collection of properties, a property containing a name (attribute name) and a value (property value).Object is an ideal choice for storing and transferring data in an applicationSecond, create an objectThere are two ways to create an instance of an object: Use the new operator followed by the object const

which to learn first. I've met all these problems before. Remember when I was just learning Java, downloaded a bunch of video tutorials online, or do not know what to look at.I'm looking for a training organization to take a timetable, from beginner to advanced, I follow that timetable, with books and video tutorial self-taught, very tired, very slow. The company's several colleagues, I also have hands-on, do not understand the question at any time t

I wrote an article yesterday to learn javascript (1) Through jQuery source code. There is a method for defining Object C in it. I didn't pay too much attention to the technical details in the early days. Later, I checked the information and found that there were many clever places in it. Today I will share with you the clever 1: Functions Functions are a rare talent in

is called (that is, this in the method), and the last is the parameter list required by the method.We know that in Java the This keyword represents the current object, we cannot modify it, and the function is called directly in JavaScript, just like a Java function call, which represents the current object.If you want to modify this, you can use apply this way.Aobj. afunction ("1");Aobj.afunction.apply (bobj,["1"]);The first way, the this in the func

, and the stack in the monitoring area. It can be cross-referenced to the recommended blog. And then another example of this oneThe code is as follows: Copy Code code as follows: var name = ' The Window '; var obj = { Name: ' The local ', Getnamefunc:function () { Console.log (this.name); return function () { Console.log (this.name); }; } }; var c = Obj.getnamefunc (); C (); Still "Step into", you can see in the execution C () This line of code, e

stored in memory, memory consumption is very large, so can not abuse closures, otherwise it will cause the performance of the Web page, in IE may cause memory leaks. The workaround is to remove all unused local variables before exiting the function.2) The closure changes the value of the inner variable of the parent function outside the parent function. So, if you use the parent function as an object, and the closure as its public method, and the internal variable as its private property (priva

closures1) Because the closure will make the variables in the function are stored in memory, memory consumption is very large, so can not abuse closures, otherwise it will cause the performance of the Web page, in IE may cause memory leaks.

assignment that does not produce any unexpected global variables, such as: function foo () { var a, b; .. A = b = 0; Two all local variables } However, another reason to avoid global variables is portability. If you want your code to run under different circumstances (host), use global variables to tread on the ice, because you will inadvertently overwrite host objects that do not exist in your original environment Always remember to declare local variables with the VAR keywor

Closures are a unique concept in JavaScript, and for beginners, closures are a particularly abstract concept, especially the definition given by the ECMA specification, and it is difficult to understand it from the definition without actual combat experience. Therefore, this article does not have a large description of the concept of closures, directly on the dry goods, let you learn to close the pack minut
