, and the browser for in case is inconsistent . The code is as follows:var b = {"Name": "Txj"function() {alert ("I am ToString")}forvar inch b) { + ":" + B[key])}We have added a prototype to the B instance that has the method ToString. Modern browsers can recycle the ToString low-version browser but not. So when you give the instance a property name, do not match the original.4, each browser loop out the order of the properties of different . The code is the same as in 2:Object.prototype.test

Fastjson This toolkit helps us to convert between Java objects and JSON-formatted strings. The process of object-to-string, which we call serialization, is, conversely, called deserialization.Now let's talk about the deserialization method provided by Fastjson, this article only discusses the deserialization method of returning the corresponding object according to the specified bytecode, which has many overloaded forms, which are designed according t

Let's talk. Recently has been studying a domestic open source of MySQL database middleware, pull down the latest version of the code to eclipse, start up, and then do a variety of tests and code tracking, when you want to close it, pull out the stop class when you want to run, found that the class is impressively only write the following lines of code, So I feel a lot of hurt in a moment. public static void Main (string[] args) { System

virtual machines" in this article refer to the Java Virtual Machine specification for both Java EE and javase platforms. Virtual Machine Memory Optimization Practice Now that memory is mentioned, you have to talk about memory leaks. As we all know, Java is from C + + based on the development, and the C + + program A big problem is that the memory leak is difficult to solve, although the Java JVM has its own garbage collection mechanism to reclaim m

Talk about JS picture front end preview of FileReader and window. Url.createobjecturl Preview Img:filereader mode document.getElementById (' Imgfile '). onchange = function (e) {5 var ele = document.getElementById (' Imgfile '). Files[0]; var fr = new FileReader (); Fr.onload = function (ele) { var pvimg = new Image (); PVIMG.SRC = Ele.target.result; Pvimg.setattribute (' id ', ' previewimg '); $ ('. Pr

; } where the transformation constructor can be used. If the + operator is overloaded, two objects of the student class can be added, and the result is the sum of the member variables of the two objects. Student S1 (01,18); Student S2 (02,20); S1+S2; The value is S1.age + s2.age = 18+20=36. So what about S1+19 (class objects are added directly to int). Since we have defined the transformation constructor, then s1+19, if the procedure: the preferred call + operator, finds that 19 is not an

For code comments, the more consistent view is that the code must have a comment, there is no doubt, but how to write a note, but there are various statements, today see a blog, the view is: note Only write why, do not write what and how. Of course, the premise is that the code can easily see what and how. Read this blog, I would also like to talk about this point of view. On the issue of annotations, I had a long time ago quarreled with one of my col

at the closure problem. I set four buttons and click on each button to return the name of the response. Click to run, but the result is all btn5; We sat down with the analysis just now, first to invoke the anonymous function-> find I, not find->btninit (), find I in the For loop. Found it. We know that only the end of the function call is released, and I in the for is always visible, so the last I value is preserved. So how to solve it. To solve the I value is not always visible

Prototypes and closures are the most common in JavaScript, the most difficult to understand, the most easily as the problem of the two parts, of course, and their extension, such as the scope chain, inheritance, and so on, I recently also a variety of look, all kinds of turn, record points of their own experience, writing will always make their own understanding a little deeper. (with the title of the relationship is not much, the emotion sentence, each time always feel that they understand, and

In order to learn the database, reinstall the system, before the eclipse, is now ready to replace MyEclipse, which of course need to reset the environment variables, write down the JDK, JRE and JVM differences and contact for the exchange of reference. First, the JDKThe JDK (Java Development Kit) is the Java Language Software Development Kit (SDK).The JDK is the core of the entire Java system, including the Java Runtime Environment (Java Runtime envirnment), a stack of Java tools (Javac/java/jd

This time the project is useful to the interface, the beginning is not particularly understanding the interface, but simply know the interface definition is very simple, even feel that this interface is only superfluous (personal development time). Now start team development, only to find that the interface is so important and convenient! Next, I would like to talk about the use of the interface of the superficial insights, said to the hope that ever

1, we will find that after the rice painting can not talk, and now we enter into the phone into the dial-up interface input *#* #4636 #*#* will automatically enter the test mode. As shown in the following figure 2, enter after we click to set the preferred network type Select LTE GSM CDMA, now we go into the wireless network open effect as shown in the following figure. 3, if not yet, click the image below Smsc Refresh, and then click Updat

function that compares the content of two objects of the same type with equality. So we have a plural class in the following design, each of which consists of a real and imaginary part. The design feature can compare whether two complex numbers are equal. The code is as follows: public class ComplexNumber {private Double re; private double im; Public ComplexNumber () {re = 0.0;im = 0.0;} Public ComplexNumber (double re,double im) {this.re = re; this.im = im; Public double Getre ()

the Ajax return results to execute the next code, if the AJAX request requires 1 minutes, the program will have to wait 1 minutes. If you're doing it asynchronously, you're telling the Ajax code. "Dude, since you're not returning the results, I'm going to wait for you, and I have a whole bunch of code to execute, so just tell me when you're done." Ajax is asynchronously requested by default, so there is the result that we see above. That is, the code inside the Ajax is not finished, the follow

Again, the cause of today's problem, input a lot of words from the front, UTF-8 format each word up to 30 bytes, so it will be in front and backstage to do the verification, JavaScript is Unicode encoding, the back-end program with the UTF-8 code, now the solution is this Front fu

But the iphone will play its artistic temperament to the extreme, "You can talk to me, but can not exceed", in the consumer electronics market, than others late 3 months and no beyond, is tantamount to death. To the extreme, the iphone survives in so many strong worlds without being plagiarized. 3. How to achieve the ultimate creativity? If we open a happy farm, the games, 4399, how can we play to the extreme

Internet pornography? Most of this article is not related to the content, I would like to talk about attention, but it happened that "title Party" is an interpretation of this attention, I also tried to do a "title party." What is attention? Believe that everyone will have their own understanding. Now what I can be sure of is that he is a very important thing: advertisers want you to focus on his ads occasionally, so he designed a gorgeous picture, fu
